[nflug] tape drive problems (scsi)

[Darin Perusich]

i'm curious as to why you are erasing the tape, there really isn't a 
need to do this. because you are using /dev/st0 you do not need to 
rewind the tape it will rewind automatically, /dev/nst0 is the no-rewind 
device on linux. try removing the rewind to see if it makes a difference.

try dd'ing /dev/zero onto the device to see if it errors? something like 
'dd if=/dev/zero of=/dev/st0 bs=512k count=10000' will write alot of 
nothing to the tape for you.
