I am relatively new to the PC3000 so finding my feet slowly. I have a drive that has a corrupted the SA. Modules do not read and return UNC errors. However I am able to re-write modules. I have tried on a couple of lower level modules and they recorded fine. As far as importance goes, I see the Ad modules are unique for the drive, B modules can be taken from same firmware etc.

So can you overwrite Ad modules? or are they drive specific? The manuals don't seem to covert that.

Ad are unique to the drive, DO NOT overwrite them.

So if these are damaged, there is no access to data apart from attempting to repair them?

It's a real PITA, but it's usually possible to bodge together one "good enough" copy and work with it, but it's not straightforward especially if the SA has bad sectors, which it usually has in cases like this.

I would think that one way to attempt a repair would be to dump all the tracks as best as possible, carve out the damaged copies from the tracks, and then try to assemble one good copy out of two. Hopefully the damage will be in different sectors, otherwise you could keep targeting the bad sector(s) in the hope of eventually getting a good read.
