Hi,

I need your help now.

I am trying to reformat my hard disk now. Because when I used unix command
"find", there is a error message: I/O error. Also many files are removed
on that disk when I used "fsck" to check the file system.

But format and label failed on that hard disk (second one in the
system). I tried to let the system re-probe it by using "probe-scsi" under
ok-mode, and the system did find it. Then I rebooted and logged in and ran
"drvconfig" and "disks" to rebuild the device files, and then ran 
"format", but I got these error messages as attached in the end of the
mail.

Could you help me in identifying this problem and suggesting possible
solutions? Is this possibly caused by a hardware failure or just by system
misconfiguration? How can I test if the hard disk is physically impaired
or not? Thanks!
