- A friend has 486 EISA system using an AMI motherboard and AMI SCSI
- controller. He has a big Seagate Wren SCSI drive.
-
- He uses MSDOS 5 with SMARTDRV.EXE configured with write-cacheing
- turned off. No multitaskers, nothing fancy except QEMM running
- in non-stealth mode. He uses the AMI SCSI device driver for safety
- even though the single physical drive would be adequately serviced
- by the SCSI ROM BIOS extension.
-
- He uses this machine to do his business stuff at home. The other night
- he was arranging things on the floor, with his machine sitting idle at
- the menu of his DOS-based billing software, when he accidentally kicked
- the switch on the UPS and powered down the system.
-
- When he turned the UPS back on, the system booted but everything
- acted funny. Lockups, etc. As a generic trouble shooting measure he
- ran CHKDSK and it found zillions upon zillions of lost and crosslinked
- clusters in the root and every subdirectory.
-
- A backup fanatic, he had a pretty current backup on tape so he just
- reformatted the C: drive and did a restore rather than fiddle with disk
- repair utilities.
-
- It's worked OK since the restore.
-
- Question: how can a power-down, with the machine sitting idle with no files
- open for writing in DOS, cause a scrambled SCSI drive?
