cyclic redundancy check

CRC is error checking. Usually means either the file is corrupt or a
hardware problem is causing file corruption in the copy process.

What are you copying?

I was just copying 20 gigs of stuff over to another drive.. but it wouldn't
even start, because the target drive had that error.

Should I just toss the drive and not risk it?
 
I'd try to copy some of the files to another directory on the same drive
first to see if it's a file corruption issue, then test the other disk
for errors. I wouldn't just toss the disk without checking it first. I'd
also try another disk cable on it. Can you copy anything at all to the
other disk?

I'd second checking the cable - the disk electronics are supposed to
detect/fix CRC errors at their end, and relocate the bad sector if
necessary .. of course, there is only a limited number of spares. It
might be interesting to fire up aida32 (www.aida32.hu) and look at the
'storage', 'SMART' tab and see if the disk admits to anything strange
going on.

Might also be worth trying the disk on the other EIDE connector (just
swap the two connectors at the motherboard end, unless you have hard
drives on the second one too, which would mess up booting), in case it
is the motherboard EIDE controller which is playing up.
 
Okay, I've tried both connectors, both ide cables and used one from another
computer.

Same thing.

All of a sudden, all the sectors showed up. I don't know why.... but I'll
take it!

Thanks for the help.

Be a good time to backup those critical files - these errors that just
'go away' are prone to come back equally fast. Keep an eye on the event
log, just in case something shows up, and if you get a minute to
download/run Aida32, it would be worth looking at the SMART data from
the offending hard drive.
 
I've since quit using the drive after transferring everything to a different
work drive.

When I get the time here I'll run Aida32 on it and see what it displays.

Thanks.
