For your consideration at this wonderful auction is a rare and vintage Apple External SCSI Hard Drive with 9GB (gigabytes) of capacity. Gigabytes are larger than megabytes. This rare drive will give your vintage or legacy Macintosh an unprecedented and spacious upgrade. The external 20SC enclosure (based on Apple model numbers M2603 and M2604) was retrofitted with a faster and more quieter 9GB drive. These beige enclosures are rare and highly collectible among Mac Classic fans. A 50-pin to 25-pin SCSI cable and SCSI terminator will be included complimentary with the drive purchased. You may use a standard power cable - does not use an external power supply. Drive is formatted with the Mac OS Standard specification allowing compatibility with 68040 and PowerPC systems, not the Mac OS Extended format (limited to PowerPC systems). Once mounted on the Macintosh Finder desktop, the drive has an available 7 gigabytes (7GBs) of free space after formatting because the operating system calculates the drive available space with an indexing system. This drive was setup, configured and tested on a Power Macintosh G3 desktop with Mac OS 9. This drive is supported with Mac OS 7.6.1 or later with 68040 systems (Mac OS 8.1 is suggested when using 68040 systems), and is expected to accommodate booting the computer with a valid System Folder. Full drive capacity will not function on System 7.5.5 or 68030 processors, it is unsupported. The yellow/orange LED glows solid when the power switch is switched from "off" to "on".

Although multiple units are available for purchase at this auction, two or more of these specific drives may not be configured together on the same SCSI bus because of the unique SCSI ID address.

Buyer or user assumes all risks, as any unusual modifications or adjustments made to the device may cause undesirable results. Additional reformatting or different drivers are unsupported.
