Glad to hear it.

In that case, you'd probably like to hear about the other disk as well.
Originally, I suspected the disk was about to fail, and bought another
one - a Samsung SP2504C. I never succeeded in copying the data off the
Seagate onto the Samsung. The farthest I got was about 2 gigs. The error
messages would be from sdb (the Samsung):

Feb 21 20:08:31 parus kernel: ata2: command 0x35 timeout, stat 0xd1 host_stat 0x61
Feb 21 20:08:31 parus kernel: ata2: translated ATA stat/err 0xd1/00 to

Feb 21 20:08:31 parus kernel: ATA: abnormal status 0xD1 on port

I didn't bring this up originally, since it looked like the Seagate
problem was a known bug, while Google didn't turn up anything on
Samsung. After reading linux-ide through gmane, I've seen similar issues
about Samsung. You guys should get an archive which Google knows
about :-)

Certainly.
