The drive in the 744 is accessible to utilities while connected by  
FireWire. I tried Disk Warrior and a couple of other recovery  
utilities. I made a clone of the damaged disk, too. Unfortunately I  
ran SD's repair utility right after the crash, which seems to have  
made the damaged files (four mono channel files of one take) more  
unreadable. I should have just left it alone but I wanted to record  
more.

I was using mono files because they were easier to load into Pro  
Tools. Now I've changed to using 4-channel poly files, figuring if  
there's damage a single file would be easier to recover than four  
files that would need to be synchronized.

I'm glad it works for you! I was really hoping the added load would  
fix it.

Not keen on running down my car battery...
