Hi,
I have (had ?) a perfectely running win98/win2000 system with a 30 Gb IBM desktar Ata100 disk.
Well, I tried DiskKeeper and O&ODefrag and several days later, the disk would not boot under Win98 (but accepted Win2k). Data were OK, as far as I can see.
The message xas : "I/O error -- Non-system disk -- replace disk and hit any key" (I translate approximately from French)
That kind of message you get with a non formatted floppy.
I rushed at microsoft.com and found very few infos - some speaking about ifshelp.sys. I replaced the damn file, tried a reinstall. No way. In despair, I formatted again the drive and it SEEMS to be working again.
For future maintenance I wonder
1) if it may be a hard drive physical error (no probs following scandisk, though - any tool to check it further ?)
2) if it may be related to DiskKeeper or O&ODefrag.
3) if a low-level fromat could possibly cure this (any tool for doing it? I haven't play that kind of sports for many years...)
Cheers.
