I've noticed the odd occasion when a bad disk will cause a crash re the
drivers that read from the drives. I'd suggest rebooting and trying to read
some known good disks. Hopefully all will go well. If it does then retry the
disks which have failed to read in the past. If when you try to read them
they fail to read again and give you the same symptoms, then the disk is
likely the culprit
