I would have attributed it to the SD card itself, except that the 
failure has happened with three different SD cards.

I've played around with that aspect a bit. I've been trying to sync 
about 25 GB of mp3s to the phone - that is, that's the size of the 
initial transfer from the desktop to the phone. Subsequent syncs should 
be much smaller, just transferring any new or changed files. However, 
because I keep having to re-format the SD card, I keep having to start 
over and suffer through the complete transfer.

It did occur to me that the failure might be related to transferring 
TOO much data at once (heat?) so I split the whole library into 4 
parts, each one being 5 or 6 GB and letting it "rest" between chunks. 
It seems to work OK some of the time, but other times it fails during 
the 3rd or 4th sync operation.

That doesn't seem to make any difference. The only way to bring the 
sick SD card back to life for the phone is to re-format it. :(

I hope it's not the phone, but I'm beginning to suspect you're right. 
I'm not in the financial mood to replace it right now, but I plan to 
try the test with another phone and see if I can make it happen there, 
too. If I can't, that should fix blame on my phone.
