There are two options:
  - Open the library, get a mirror and flashlight to try and read the label off
    the drive.  For example:  FECODE   8CC-0730
  - Try the following AIX trace:
      + trace -3
      +     -> trcon
      + Start some ADSM activity to the drive, like a MOVE DATA
      + Cancel the ADSM activity
      +     -> trcoff
      + trcrpt -t /usr/lpp/adsmserv/ps_format.trc /var/adm/ras/trcfile.3 > file
      + Search the file for dd_check_condition
      + Look for a nearby string like EXB8500C8CQANXR40730
      + The last four digits are supposed to be the microcode level.

I have not personally tried the trace, so this may not be exactly correct.
