Hello,
I would suggest give HBA & Overland support a call, there may be specific
driver & HBA bios settings that may need to be applied.
As a test try backing up directly via Windows utilities, this may help you
isolate problem within Legato or OS. I would also suggest using adaptec
drivers.
Are there any errors in the Windows EventLog ?

I'll try to answer these best I can ...
1) The tape heads were cleaned to begin the process, and I have cleaned
them once since. So, best I can tell, the heads are clean.
2) Have not run diagnostics specifically on the Overland, but I have tried
two separate Overland Powerloader LTO jukeboxes, both with the same
result. So, since I've tried a couple of different units, that was my
attempt to rule that out as a possible reason.
3) I am receiving the errors on multiple tapes. In fact, I recently took
out a few tapes that were empty that I had been attempting to use and
replaced them with newly opened tapes, and the result has been the same.
This is one thing I have done that may be helping though ... last night, I
changed out the SCSI card for another one we had, a LSI Logic PCI-X
Ultra320 SCSI host adapter. Windows picked up on it right away, it appears
to be using a generic Microsoft driver (which is different than the
Adaptec, which was using a newer driver from 2007 off their site).
When I attempted to re-run the tape label from the GUI, it did not take
the long period (30 minutes) to time out, it finished its efforts in about
2 minutes. The error I got then was a tape rewind error, saying that the
tape status was that the drive was ready.
Additionally, when I ran scanner -vv \\.\Tape2, it did not show the block
error. It then (properly I think?) showed the default block size zt 32kb,
and the maximum at 64kb.
Not sure at this point, might be making progress on it, hard to say. What
settings in Networker should I be looking for at this point, should I hard
code the HBA size to 64kb or leave it at handler default?
