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 ?
HTH

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?
