[ILUG] DAT problems

Andrew started the ball rolling today with SCSI device problems, so I'll
continue in like vein. I've been using amanda with a DDs-3 drive reasonably
happily EXCEPT that quite often when I try to verify a tape, I get errors
like this:

gzip: stdin: invalid compressed data--length error
/bin/tar: Skipping to next header
/bin/tar: Archive contains obsolescent base-64 headers
/bin/tar: Error exit delayed from previous errors

I swapped the drive out with another drive and still had the errors. Luckily
on the few occassions I've had to restore a file I could do so, but I'm
skating on VERY thin ice.

I did a test where I tarred a couple of big files onto a tape and then took
them off and got md5s of the in and out files and they were different but I
saw no errors from tar while doing this.

So, where do I look now to find out what's causing this breakage ?
