I was backing up my Lisa Pascal Workshop 3.0 disks using BLU last night and was getting really pleased that they were all reading without any problem. Until disk 8, which nearly finished before catching on sector 29 :( I assume it was a bad sector because the drive head kept seeking, presumably to track zero and back to retry the read? I let it keep re-trying for a couple of minutes in case there was a timeout, but finally interrupted it. Is there a way to get BLU to skip bad sectors?

IIRC, normally BLU will retry briefly, including a recal to track 0 once, then report the error and give you some choices:
F - Fail
R - Retry
G - Read Ignoring Checksum (has never been useful in my experience, but the FDC offers it)
V - Read Varying Speed (Twiggies Only)
S - Skip This Sector
If you want to continue with the rest of the disk, you would use S - Skip This Sector
However, from your description, it sounds like BLU is retrying continuously without you asking it to... is that correct?
If so, please turn on Verbose logging (in the Miscellaneous menu), and send me an email with some of the logging output that is sent while it seems to be stuck in the retry phase.

Yes, it sounds like continuous retries. I will send you the logging.

From the looks of it, BLU isn't seeing an error. Here's the tail of the log:

It is at this point the drive just keeps retrying. I can't tell if it is actually seeking to another track and back, or changing the drive speed. But it just keeps going for minutes until I interrupt with the clear key.
