How to reclaim device name after malfunction?

Hi

Sometimes when I hotplug a SATA device to/from say /dev/sdb on my
Mandriva 2009.1 system, it malfunctions/times out, and cannot be
detected. Then when I plug in another SATA device, it gets detected
as /dev/sdc even though /dev/sdb is no longer there. How can I
reclaim /dev/sdb in this case?

Thanks

You can't (short of rebooting).

You should consider volume labels or UUIDss and not depend on SCSI device names.

I have never gotten anywhere near sdz (using Redhat) but I assume there is
some scheme after that. Why is it you want to recover it? If you have some
mount script look into

mount -L label

and see if that is not a better way to do what you want.

As another shot in the dark I have found it the least frustrating to turn off
all automount procedures for a DVD/CD drive.
