My fix also corrected some problems with some of the "quirky" 525MB 1/4"
drives, according to Joerg Wunsch, which I thought it might when
I wrote the fix.  Since I don't have access to anything really
fancy or state of the art (just an old Archive 2150s), I can't verify 
if the above fix corrects some of the other "odd" SCSI tape bugs 
that have been reported lately.

The above problem ("bad request, must be between...") seems to come up 
here and in USENET fairly often, so perhaps this fix should be imported 
to the 2.1 -stable tree?
