System 7.5, Version 7.5.3 comes with two Disk Tools disks:
* Disk Tools 1 - for 68K computers with SCSI hard disks
* Disk Tools 2 - for all PowerPC computers, and the following 68K computers that have IDE hard disks:
Macintosh LC 580
Macintosh LC 630
Macintosh LC 630 DOS
Macintosh Quadra 630 series computers
Macintosh Performa 580 series computers
Macintosh Performa 630 and 640 series computers
PowerBook 150 series computers*
PowerBook 190 series computers
If you have a 68K computer and have installed a PowerPC Upgrade Card, you should use the Disk Tools 2 disk.
If you insert one Disk Tools disk into your computer and you see an error message on the screen telling you the wrong Disk Tools disk was inserted, use the other Disk Tools disk.
Using Drive Setup
This Disk Tools 2 disk comes with a new version of Drive Setup (version 1.0.4) that fixes a problem that occurred with some types of IDE hard disks. If your computer has an IDE hard disk, you should update your driver as part of the installation of this software. When using Drive Setup on some IDE hard disks, the "Update driver," "Customize volume," and "Test disk" options are dimmed. To use these options, back up all data from the IDE disk onto another disk, and use Drive Setup to reinitialize the IDE disk.
*Special note about PowerBook 150 series computers
You do not need to update the driver on your hard disk (as described in the user's manual) with Drive Setup. (The driver on your computer is contained in its ROM.)
