Yeppers, I wasn't the sysadmin at the time, but some schedule of testing
was done. The tape drive was what crashed the machine, and it did so with
the spectacular results one would expect from a 1000W switching UPS
(spitting hot metal which KOed the disk). No other tape drives would read
it, and I believe a data recovery service made $1000 evaluating 5 tapes (at
$200 per tape) to report that nothing was recoverable. The WorkGroupServer
Motherboard and case and floppy were reused, but not as a WGS. The HDD,
the tape drive, the power supply and the cabling had to be trashed.
And you are exactly right, no other tape drive would read the tapes.
