I have an ST-251 and an ST-251-1. The -1 had a few more badblocks, but no
heat damage on the PBC where the normal 251 had it. Both are still
working but they seem slower than the RD54 to me...
The -1 is no better. Considering they are a stepper they would be slower
than the RD52,53,54s that have both more heads and voice coil positioner.
I don't have any idea about the drives used in a DEC environment, but in the
IBM PC world, the best program I have found to date is Spinrite for doing a
check of the HD media. Having used Nortons NDD, that joke of a program
called Scandisk, and a couple of others, Spinrite is the only one that has
never caused more problems than it solved. I just ran Scandisk on a Win98
drive that was beginning to fail resulting in the drive being unreadable.
Ah, the fun of working with computers!
