I'll have to look -- I *think* they're both on the same tape, LTO-4. We've only 
got one LTO-4 in the library showing errors, and it's in a different storage 
pool.

I'm still bothered by the fact that the TSM server goes into 'sendw' and shows 
300 to 500 Bytes per second transfer rate to the Win2003 system -- which is 
showing 99% CPU usage in System Idle Processes (and I'd love to kill the 
MickeySoft idiot who decided to report network overhead as 'system idle').

Hey Tom,

THAT is an interesting bit of information.
What media is that 38GB file on?  Do you know the volser?
If I were going to work on it, the first thing I would do is copy that tape
to a different tape and then try the restore again.
