Directions

We sell several kinds of hard drives, ZIP drives and CD-ROMS for your Mac. This Web page assumes you know about SCSI drives versus IDE/ATA drives, and external versus internal drives, and active termination versus resistive termination. If not, go to my detailed and technical discussions of my hard drive and CD-ROM inventory. If you want an old Apple brand drive like a HD20 or HD 20 or HD20 SC they are also in my collectables Web page. Our floppy drives & diskettes are on another page. Sorry I maintain many pages, but there's a lot to say and I have a lot to sell!

Go to our Mac home page for links to the other Mac systems and accessories I have available. Follow this link to contact me and to see ordering information and terms and conditions of sale.

Introduction

We sell hard drives and CD-ROM drives, for older Macs. We have both Apple brand and non-Apple brand drives. We have internal drives, and external SCSI drives (which are just internal SCSI drives in a case with power supply). We also offer external SCSI cases without drives. We don't provide "how to install" instructions or technical assistance beyond the notes elsewhere on our Web site. Check my more detailed drive page as mentioned above for links to that info. Items on this page of SCSI drives, and links to other pages, are:

Internal Mac-formatted hard drives

Internal Mac-formatted SCSI hard drives

I have internal SCSI hard drives available for the Mac, from 80Mb to a few Gigabytes. Typical drives from several manufacturers are immediately below. Newer, larger drives are in the next section. Shipping weight 2 lbs for one drive, add one pound per additional drive. "1.5 inch tall" drives are a little taller physically than the typical 7/8" high drives like the one pictured here, they are also older but they are cheaper. Drives below are all 5400RPM drive; if we have 7200RPM drives they are in the next section.

More information

For laptop drives, check my page of Mac Laptops drives.

Apple "branded": The drives I sell are Mac tested, partitioned and initialized. Mac hard drives require "initialization" and "partitioning", some call this "formatting". There's issues about doing this under System 7 and earlier, with drives not purchased from Apple which I call "not Apple branded", and about partition sizes. Check my Mac Frequent Questions, about drive partitioning and init, for details.

Don't forget a drive bracket carriers or sled if you need one. For more technical information and pictures, check my SCSI drive technical page. See this Web page for descriptions of SCSI connectors.

As of 2011, we only have a HANDFUL of working SCSI drives. They are getting old and scarce to be in working order. Be prepared to accept a larger or smaller drive than you request. Also consider whether you need an "Apple brand" drive or not. If you want a specific brand and model I charge more, if I have it.

advanced SCSI hard drives

The SCSI drives listed below are NOT "Apple branded"; we will init or format them for System 7 or OS 8 or OS 9 use. Drives at 7200 RPM provide data FASTER than the more typical 5400 RPM drives. All drives are used, tested and Mac formatted. All of these have the Apple/Mac typical SCSI drive connector: 50-pin flat cable. For technical specifications, use the brand name and model in a Web search to get that information. Only a few drives available per description. When you order, please copy the description below into your email order; and make TWO choices so I can more likely provide one of them!

advanced SCSI-2 hard drives and Apple controllers

The following drives are for use with Apple's SCSI-2 drive upgrade, which provided higher performance than Apple's on-board SCSI-1 controller and SCSI-1 drives of the era. The upgrade consisted of a PCI SCSI-2 card and SCSI-2 cable, to these SCSI-2 drives. The SCSI-2 drives below are used, tested and Mac formatted. All have the SCSI-2 drive connector: 68-pin D-shaped connector. See this Web page for descriptions of SCSI connectors.

The PCI ultrawide SCSI-2 PCI cards and cable are available via this link.

See Apple's Web page for a description of the SCSI upgrade. For additional technical specifications on these drives, search on the Web for these brands and models. Only a few drives available per description unless noted below. When you order, please copy the description below into your email order; and make TWO choices so I can more likely provide one of them!

Internal Mac-formatted IDE drives

For laptop drives, check my page of Mac Laptops drives

I have 3.5-inch internal IDE, ATA or EIDE hard drives available for desktop and tower Macs. Shipping weight 2.5 lbs for one drive, add 2 lbs per additional drive. All drives are tested and formatted on Mac equipment - that effort sets a minimum price.

The drives I sell are Mac tested, partitioned and initialized. Mac hard drives require "initialization" and "partitioning", some call this "formatting". There's issues about doing this under System 7 and earlier, with drives not purchased from Apple, and about partition sizes. Check my Mac Frequent Questions, about drive partitioning and init for details.

Don't forget a sled carrier or bracket if you need one. For more technical information and pictures, check my (mostly) SCSI drive technical page. See this Web page for descriptions of SCSI connectors.

IDE drives under 400Mb: only by request, minimum price $35 due to age.
IDE drives 450Mb to 1.5Gb, $25 plus ship.
IDE drives 1.9 to 3.0Gb, $29 plus ship.
IDE drives 4.0GB to 6.0Gb, $35 plus ship.
IDE drives of tens of GB available, ask.

Requests for specific drives by brand and model: add $5 to above prices unless listed below. Older Macs (or Macs running OS 7.X) may not be able to handle drives above 2GB unless "inited" with smaller partitions. YOu may need an "Apple branded" drive for some early systems.

Sleds, carriers, rails, brackets to mount drives and CD-ROMs

Most Apple computers have a sliding base for the hard drive or floppy drive or CD-ROM drive. A plastic part is screwed to the drive. This plastic part is generally called a carrier or "sled" as it slides in and out of the Mac case. Here's an image of some floppy drive and CD-ROM plastic sleds. Also, early Macs used a metal frame to hold drives, so did the G4's and G5's. Or, a drive may have "rails" on either side which slide into the computer. We have those too. Please tell me the model Mac you have if you order these parts. If you can, look for the Apple part number molded onto the part, if you have the part.

Most CD-ROM drives and internal hard drives require a sled or rails which attach the drive to the Mac cabinet. Sleds are typically plastic devices which screw underneath a drive. Rails are a pair of plastic bars which attach to either side of a CD-ROM, for Macs like the 7100 which have drives that slide in and out. Brackets are typically pieces of sheet metal which form a cage around the drive; these are more common to older, pre-PowerMac systems.

screws and standoffs

In external drive cases or enclosures, there may or may not be "sleds" or "brackets" - there are no standards, every brand and case is unique. In many cases, drives are screwed directly to some surface or to some raised platform. It's generally a good idea to make sure the "bottom" of a hard drive (usually the top of its circuit board) is not in direct contact with a metal surface. Such contact limits air flow for cooling, and increases the chance of shorting out electroni components. Consider the use of screws with "standoffs" or with short lengths of metal or hard plastic rod, to provide some "air gap". That screw hardware may be available from large hardware stores.

Be sure that any screws used to hold drives are of the right "size" - diameter and thread pitch. Again, there's no sandards. Don't "force" a screw, that suggests it's the wrong size. I cannot provide further information on the general use of screws, standoffs and fasteners. I cannot guarantee that drives and cases I provide will include all needed fasteners.

Apple Mac sleds, carriers and rails

Here's an image of some floppy drive and CD-ROM plastic sleds. I do not guarantee the system lists below for each carrier sled, look at parts on your own system to buy duplicates, etc.

plastic CD-ROM sled 5.25-inch drive sled for most Macs, stamped 815-1122, Apple part number 922-0850, are $5 each.
Plastic 5.25 sled with mounts for 3.5" drives (see photo above), found in PM 6400 and 6500 systems, stamped 815-2501 or 815-2730 - ask if available.

plastic 3.5" hard drive sleds:

---sled with 1.5 inch wide "wedge" or stop, 815-0446, 922-0621, $5 each
--- used for 7000, g3, 6100, 8100, 9500, etc.

---sled with 1-1/8" wide "wedge" or stop with square hole, 815-1688 $8 each
---used for grey G3 model ATA drives near motherboard

--- rectangular sled 922-0445 $10 each
--- no wedge, drop-in and lock. for 8100, 8500, 9500, 610 systems.

CD-ROM rails (for 7100 Macs and others) are $6 a pair.
metal brackets to hold or encase a drive (Mac II series and compact Macs) vary in price, specify your Mac model.
G3 tower, 8600, 9600 bracket for ATA drive: 805-1464-B $5
G3 tower, 8600, 9600 metal shelf for drives: $3
g4, g4 metal sleds: $3

carriers, brackets: Some hard drives are held in a metal carrier, case, or bracket. I describe these on my Mac Parts Web page under floppy drive carriers, as most Macs use these cases for floppy drives. If your Mac hard drive needs one of these, tell me the model Mac you have, and I'll see what I have available. Generally these carriers have a stamped part number on them, if you have one to reference.

CD-ROM wiring adapters for 6300, 630, etc.

SOme Mac models (630 series, 6300 series, 6400 series, 6500 series) used a wiring scheme that required two "adapters" on the back of a CD-ROM to "plug into" the cabling. One adapter has a 50-pin and a four pin adapter for SCSI and power (Apple number 613-0312). The other is a four pin connector for audio (unnumbered). Here's a photo of some in a baggy. Contact me about price and availability.

When ordering, please follow this link for ordering information, terms and conditions, and info about orders outside the USA.

CD-ROM drives

For laptop drives, check my page of Mac Laptops drives

INTERNAL CD-ROM drives

Tell us your Mac model (and CD-ROM model if replacing one) when ordering. Don't forget sleds or mounting hardware, we have that stuff too. Shipping weight of these drives, 3 lbs. Drives are tested again before shipping. For more technical information and pictures, including "caddy" pictures, check my SCSI drive technical page. cable and terminator sold seperately. If you are trying to "upgrade" your Mac to a faster drive, please note that very old Macs using System 7 *may* not accept the newer drives such as 8X or 12X. However, due to age and increasing rarity, the oldest Mac CD-ROM drives will cost more than newer models. Be sure what you buy will work with your particular OS and Mac.

SCSI CD drives:

Apple 150i or 300i internal drives which use a caddy, $49, caddy extra. Here's the CD300 type drive.

When ordering, please follow this link for ordering information, terms and conditions, and info about orders outside the USA.

EXTERNAL CD-ROM drives

We have a number of external CD-ROM drives, but they are getting harder to find, so prices rise as demand continues. Ask for details and include the model of your Mac. If you are replacing an external drive tell us its model and manufacturer. Typical shipping weight of external CD-ROM drives is 8 lbs. SCSI cables, terminators and CD-ROM caddies are sold seperately.

Note: we ofer some of these in non-Apple cases or in Apple cases labled for other Apple drives. THE DRIVE DETERMINES THE SPEED AND FUNCTIONS, NOT THE CASE. The case is only a box. OK? "Caddy" versus "tray" is discussed

Apple CD150, with CD150 case and 1X Apple drive 150, requires caddy. SCSI-1 connector. $79 plus shipping if available.
Apple CD300, with CD300 case and Apple drive 300, requires caddy, SCSI-1 connector. $59 plus shipping.

We may have some of these Apple CD 300 or CD 600 drives in non-Apple cases - ask

CD-ROM caddy or caddies: purchased with CD-ROM drive, first one $2, subsequent ones $3 per caddy; without drive $4 each. You do not need these with tray-type CD-ROM drives. Caddy and trays are discussed on my SCSI drive technical page.

The Apple CD SC or AppleCD SC is described and priced on a seperate page; follow the link.

When ordering, please follow this link for ordering information, terms and conditions, and info about orders outside the USA.

IOMEGA ZIP 100 or 250 drives, disks, hardware

ZIP drives may offer you a way to move megabyte-sized files from old Macs to new. There are USB ZIP drives available for iMacs, eMacs and so on; and SCSI ZIP drives for PowerMacs and older. If you don't have a CD writer, ZIP disks are good for backups. Pentium/Windows PC's can read ZIP disks, we have some parallel-port external ZIP drives for those systems as well. You may also need a sled, bracket or screws to attach internal drives.

We have a number of IOMEGA external 100MB SCSI ZIP drives. These are complete with cable (DB-25 to your Mac) and AC power supply. Used but tested and working OK. 1.4M Mac floppy with ZIP drivers V4.3 included, check the Web for other software. $49 plus shipping, shipping weight 8 lbs. (Note: we will not sell "ZIP Plus" drives because they are known to have problems.)

We also have a number of IOMEGA external 100MB parallel port ZIP drives. These are for Windows and PC systems, not for Macs. 1.4M windows/DOS diskette with ZIP drivers included, check the Web for other software. These are complete with cable (DB-25 to parallel port) and AC power supply. Used but tested and working OK. $29 plus shipping, shipping weight 8 lbs.

We also have a number of IOMEGA external 100MB USB ZIP drives. These are for Windows and PC systems AND for Macs. Most computers which have USB will have an operating system which will accept USB ZIP drives. Check the Web for other software. These are complete with USB cable and AC power supply. Used but tested and working OK. $49 plus shipping, shipping weight 8 lbs.

We also have Zip 100 internal 100Mb drives, either SCSI or IDE (ATA).
Working, pulled from Mac and PowerPC or Pentium systems. shipping weight 4 lbs.

Unused ZIP drives are on my new parts page. (Note: ZIP drives don't need to be "Apple branded" to work with older Mac OS's, as do hard drives.)

ZIP 250 drives: Pulled primarily from Windows/PC systems, internal or external. ask about price and availability, will cost more than 100MB drives of similar connections.

ZIP disks: Used ZIP 100 disks, $5 each plus shipping. UNUSED sealed ZIP disks, $9 each. Specify if you want "MAC" or "PC" disks, these are pre-formatted for Mac or PC use. Generally you can reformat (init) a ZIP disk on a Mac or a PC - some customers prefer not to do that.

For specific Mac models, we have ZIP drive mounting hardware and front panels. PLEASE name your specific system model! With ZIP drive, add $5. Bought seperately, $10. You may also need a drive mounting plate or screws; drive sleds and related information are in another section of this page.

External hard drives

When ordering, please follow this link for ordering information, terms and conditions, and info about orders outside the USA.

EXTERNAL SCSI-1 hard drives and cases

We have a variety of external SCSI hard drives, mostly one or two of a kind. Drives are tested and inited/formatted on early Macs. All have A/C switches and outlets for A/C cords (cords included); and cooling fans for the internal power supply. They may have other features, we'll list those individually. Some of our stock is described below by model and capacities. A description of some common cases we have follows that list.

See this Web page for descriptions of SCSI connectors. For more technical information and pictures, check my SCSI drive technical page. SOme drives are described as not "Apple branded" drives that means System 6 and 7 Apple utilities won't "init" these drives, you need other programs to do that. Please follow the Web link for further descriptions.

My apologies for all these "technical" details. But the fact is, these drives are no longer made, and few technical people today know these details. YOU, THE VINTAGE MAC OWNER will have to be your own "tech support" and know what you are buying, to keep your vintage Mac in use. That's our policy, informed customers. - Herb Johnson

external SCSI hard drives

I have assorted external SCSI drives from a few hundred Mb to a few Gb. All are tested and working, in clean external drive cases, with AC cords (not "wall warts"). They have SCSI-1 connectors on the back unless noted, and will need SCSI-1 cables and possibly terminators, sold seperately.

As of June 2012 we have several external SCSI drives in cases. We have also have drives, and cases without drives. Contact me for what I have available and prices. Items below are examples based on recent stock, not all may be available and we may have others. Prices will start at $59 plus shipping, due to rarity of good working SCSI hard drives AND the difficulty of installing drives in cases to match internal cabling.

The Apple HD20, HD 20 and HD20 SC are described and priced on our "collectables" page; follow the link. Check our hard drive technical section for a review of the HD20 and its use on 128K's and 512K's.

When ordering, please follow this link for ordering information, terms and conditions, and info about orders outside the USA.

External SCSI-1 hard drive cases

I have a number of various small and large external SCSI drive cabinets, without SCSI hard drives or CD-ROMs. Many have a SCSI-1 connector, a few have the older DB-25 connector. They all have an internal SCSI cable and power cable that's compatible with older Mac SCSI-1 hard drives. We test the power supplies on these and can run a hard drive to test the SCSI cable. That's the limit of our testing. Shipping weight typically about 10 lbs with drive and SCSI cable, 6 lbs for case only - we will quote shpping based on actual weight and size.

Sold with tested and working power supplies, and in acceptable or better cosmetic condition. Some have open fronts for CD-ROM drives, most are closed and so for "internal" SCSI hard drives only.

What's involved in putting a SCSI hard drive in a case?

You might use these to power and contain SCSI hard drives or CD or DVD drives. YOu will also need external cables to connect them to your Mac's SCSI controller; we have SCSI-1 to DB-25 cables for these, and some DB-25/DB-25 cables too. See this Web page for descriptions of SCSI connectors.

If your Mac does not have a SCSI controller, you will need one. See my Mac Web page of Mac cards for SCSI controllers. You may also need a sled, bracket or screws to attach internal drives.

Note on SCSI addressing: Drives in external enclosures have cables to the SCSI drive address jumpers, which connect them to the case's "SCSI address switch", a numeric switch which allows you to change the SCSI address of the drive without opening the case and changing these jumpers. The problem is that the drive's SCSI jumpers are not "standard" for all SCSI drives. So a connection for one kind of SCSI drive's address switch may not fit another drive. The alternative is to put physical "jumpers" on the drive's jumpers and ignore the SCSI address switch and wires. See this section to see photos and buy jumpers.

There's a similar issue for the case's LED "drive ready" light - it needs a cable with a connector to match the drive's. No standards for that.

SO, because there's no standards for SCSI addressing cable or drive-ready LED cables, we can't guarantee a case will "fit" those connectors on your drive. But the SCSI-1 cable and power connectors ARE "standard".

If the above is technical gobbley-goop (makes no sense to you), please don't buy a SCSI case from me. This is not "plug and play" technology. Check some of my "frequent questions" on my Mac frequent questions page and some of my other SCSI Web pages for more information.

Typical external SCSI-1 drive cases

As of June 2012 I'm working on photos and descriptions of our SCSI-1 external drive cases. Some examples are below. Ask me what I have and current prices; but I won't sell a case for less than $25 plus shipping. If you want a SCSI external case with hard drive, I have those listed seperately. I may also have those cases available without drives, ask me. - Herb

Here is a Mirror brand external hard drive cabinet, which requires a 50 pin SCSI-1 cable. It is typical of the SCSI cabinets we have in stock. The low-profile cabinets are 2.5" to 4" tall and about 10" by 10" or so, and hold one 3.5" SCSI hard drive of about 1" height. high-profile cabinets are about 5" tall and will hold a full height (2" or so) SCSI drive. The back of cases have a SCSI ID switch AND some have *AC outlets* to switch both your Mac and another AC device! Most of these cabinets do not have a switch for SCSI active termination, the drives in them have passive termination (good for very old Macs) or you can use a SCSI-1 terminator.

THey will have SCSI-1 connectors and may have SCSI address selectors on the back - but I cannot guarantee those selectors will exactly "fit" your drive. Most have audio/RCA plugs on the back for audio connections. ask for price and availability, shipping weight 8 lbs.

SCSI-2 external cases

"SCSI-2" refers to the SMALL narrow D-shaped 50-pin connector. (NOT the LARGE 50-pin Centronics SCSI-1 connector!) Some Mac controller cards, and USB to SCSI controllers, have a SCSI-2 connector and so these cases support that connector. See this Web page for descriptions of SCSI connectors.

The following are small white cabinets, measuring about 10 or 11 inches wide by 10 or 11 inches long, 3 inches tall for the one-drive cabinets. They include an AC power supply, and they use a standard "computer" A/C power cord. While these held 5.25 inch SCSI-1 drives, you can add "rails" to fit 3.5-inch SCSI drives. Cabinets have SCSI address switches but the wiring for these may not fit your drive's SCSI address jumpers. Prices do not include shipping. Shipping weight for single-drive cabinets is about 9 lbs; for double-drive cabinets about 12 lbs.

See my note on SCSI address switches and jumpers, for a discussion about connecting SCSI drives inside SCSI cases. You may also need a sled, bracket or screws to attach internal drives.

Photos of the one-drive cabinet:
Here's the outside; here's the inside; here's the back with SCSI-2 connectors.

case 3.0" high, SCSI-2, will hold one SCSI drive, closed front, $39
case 3.0" high, SCSI-2, will hold one SCSI drive, open front (CD or DVD), $45
case 7.5" high, SCSI-2, holds two SCSI drives, open front, $55.

External SCSI drive, 25-pin DB-25 connector

I have a few external drives with 25-pin connectors on them, like the SCSI connector on the Mac. They mostly have low-capacity hard drives, or the drives have been removed. We don't recommend these. we recommend you buy a case with a SCSI-1 connector and use a DB-25 to SCSI-1 cable. If you insist you want one of these cases, as of Jan 2012 we'll price them from $39 plus shipping. Let me know your considerations and I'll offer a selection - please don't ask for "like new" condition, they are all "old".

SCSI controllers

Check my Mac NuBus section for Apple and other brands of NuBus and PCI SCSI controller cards: these are used pulls from Mac computers. Pentium/Windows SCSI controllers are available from me, ask for specifics and say if you want 8-bit or 16-bit ISA, some PCI, some VESA local bus(!).

SCSI cables and terminators

USB (or FireWire) to SCSI "cables" is an incorrect way to describe what is a device or controller. These are not wires or cables but electronic devices. See my USB or FireWire to SCSI controllers Web page for more information. See this Web page for descriptions of SCSI connectors.

SCSI cables, terminators:

DB-25 to SCSI-1 cable, 1 to 2 foot $8
DB-25 to SCSI-1 cable, more than 2 foot, $12-$20 depending on length.
DB-25 to DB-25 cable for SCSI, 1-2 foot, $10; longer costs more, ask.
DB-25 SCSI terminator - ask
SCSI-1 to SCSI-1 cable, under 1 foot $8; 1-2 foot $10; longer from $15 depending on length.
SCSI-1 external terminator $8
SCSI-1 terminator with SCSI-1 connectors at each end, allows both cable and termination, $10.
SCSI-1 "active" terminator, has LED, $12
Powerbook or Laptop SCSI cables: see my Mac Laptop page.
SCSI-2 to SCSI-1 cables: $20 for cables under 18 inches. Ask about longer cables or adapters or SCSI-1 to whatever connectors.
SCSI-2 external terminators: $12
cables with different SCSI connectors: specify connectors and length. Limited supplies.

The Macintosh IIfx apparently had an internal SCSI termination block. Check our Mac II systems page for specifics.

drive jumpers, straps, shunts

Hard drives and CD-ROM drives are set up at the factory or by installers with particular features; such as a SCSI address, or "master" or "slave" for IDE or ATA drives, and so on. These features are set up by using tiny "jumpers" or "shunts" which short out connections between physical pins on the drive.

At the drive end, these pins are usually in rows of pairs, on the edge or the back of the drive. Older hard drives, and CD-ROM drives, use rows of jumpers that are seperated .1 (one-tenth) inch apart. Newer drives may use jumpers that are 2mm (two millimeters) apart. Here's an image of a drive with .1 inch jumpers in place. Measure the space between your drive's jumpers to determine what size you need. Of course the jumper blocks are wider than the .1 inch or 2mm space between the rows of pins they "jumper".

Drives in external enclosures, often connect cables to the SCSI drive address jumpers, which connect them to "SCSI address switches", numeric switches which allow you to change the SCSI address of the drive without opening the case and changing these jumpers. Look at our section on external SCSI drive cases for further discussion.

2mm hard drive jumpers. $1 each plus shipping and handling. If ordered seperately, minimum charge of $4 for first class mail within the United States. We suggest you order these with other items.

.1 inch hard drive jumpers. 2 for $1 plus shipping and handling. If ordered seperately, minimum charge of $4 for first class mail within the United States. We suggest you order these with other items.

Roland sampler and SCSI drives

Note for music sampler customers: some people buy external Apple brand Mac SCSI drives (hard drives or CD-ROM drives) and cables for their digital music sampler equipment. Roland is one manufacturer of audio samplers samplers. Please do a Web search for your sampler to confirm Mac or SCSI drive by brand compatibility, or for more information. I have a bit of info on this page, and a FAQ (frequent question) reference on my Mac FAQ page. When ordering from me, tell me what kind of SCSI connector is on your sampler so I can possibly offer a matching cable. I don't have your sampler so I can't test and guarantee results. But a number of customers have bought old Apple Mac SCSI drives and seem to use them OK.
