Well, I just tried doing this (actually, bs=64k, not bs=64, which would
yield less efficiency), and partway through my files, I got a:
tape transfer error, unit 0, grp 0x100, event 0150
I tried this over again, and even went as far as to try using another
TK50 and a different tape. If I let the writes go on too long, I get a
kernel panic, and something about uda0. I wouldn't know where to start
with using the debugger, so I kept trying it over again.
Do you know what this error means? I can't find any info on it in any of
the manpages. Again, I'm using snapshot 1.1A, with the kernel that came
with it.
