I should leave that to the SCSI-device.Quote:>I've got a SCSI hard drive w/ a bad block. It gets reported int to

Utilities exist to change the configuration of SCSI-devices.
Look around on bulletin boards for SCSICNTL.EXE or something like that.
Linux comes with a utility like that too. I have no experience
with it though.
Good luck,
Toon.

We bougth here a 1G scsi drive for an AcerPower 433 computer in our lab.
The computer has an integraged SCSI interface (a 152x job) and an IDE
interface. Everything worked fine for a few weeks but now reading some
specific files hangs the SCSI interface (I need to reboot using the reset
button). The scsi driver prints the message:
nele kernel: scsi0: resetting for second half retries.
and I cannot access the disk anymore. After reading the SCSI-HOWTO it
seems that the most probable cause for this are bad-blocks.
My questions are:
1.- SCSI drives have an internal list of bad-blocks (true?) how do I
force a disk check to update that list?
1a- If I should use an utility to check for bad-blocks, would it crash
also since the problem ocurrs at the kernel level?
2.- Is this normal? I formated the drive and received no error messages
and now I am encountering all this problems. What can be creating this
errors, can heat be a problem?
3.- Isn't device drivers reentrant? Why would the kernel block any
further access to the disk? I guess the problem is with the SCSI interface.
4.- Am I wrong to assume that the problem is related to bad-blocks?
Phew!! Thats it... Thanks for any help you can give me with this. I am
using kernel 1.2.8.
