My RT seems to have a bad drive 2 or controller. Here are the
messages printed by the kernel:

This is not the first time this has happened. I have reformatted all
drives; this did not help. Drive 2 sometimes makes a whine that
sounds like bearings are worn.
Please have someone run diagnostics on this machine, and if possible
replace drive 2 (drive 2 is an IBM 310 MB disk; when I say "drive 2" I
mean the drive in the front of the machine under the floppy drives).
Relevant information:
Machine name: achates
Location: E40-342, SW corner
Machine type: RT 6150
Serial number: IBM 26-0002036, MIT tag 0233177
Contact: John Carr (jfc)
Contact me before doing any work. I need to shut the machine down; if
a drive needs to be replaced I also have to copy the data.
