If the SD utility was not able to fix the corrupted directory, they
need to address that too. I've had no issues with SD's repair
utility-- but I've only used it a half dozen times. In theory, it
shouldn't make a difference how many files there are or their formats.
Its very possible that simplifying the interface from the Mac to the
Message: 2.
Subject: 5" drive might be more successful. Many times I found the FW
interface itself to be at the bottom of both internal and external
drive problems. SD had a heck of a time implementing FW.

I'm surprised it didn't and I'm even more surprised that SD could
still be hunting for answers. I was about to send my 744T for a
hardware upgrade,.. I'll wait on that now.

Dropping it under 10 volts once shouldn't hurt it. Or use an older
battery that will still output voltage for a while. Reporting to SD
that you've tried several battery types without success points to
hardware/firmware differences between our 744's. Rob D.
