After using Drive Setup 1.3.1 to update the drivers for a hard disk drive, the computer may not start up due to an issue stemming from running Drive Setup 1.3.1 while At Ease Security was active (see article 22101: "
Global Product Support Flash: Drive Setup 1.3.1, 1.4 and At Ease").
There is a workaround for the Disk Setup 1.3.1 and At Ease Security (disk locking) issue. Follow the steps outlined below:
1. Restart your computer from a system CD-ROM disc.
2. Run Drive Setup 1.3.1 from floppy disk.
3. Update the drivers again and restart your computer.
4. Run Disk First Aid to make repairs to any errors returned.
This process should be attempted before formatting your hard disk.
