Hopefully this will be the last question regarding this subject:

What happens if the checksum finds an error? Is there anything you can do about it?

For example:
I just checked the md5 file for Disc 4 in the Jewels and Binoculars 1966 (26 cd set) - which I got here.

This is the error I got from xACT (checking the file(s) that I b/u'd to DVD-R):
d04.md5: FAILED
Track01.flac: OK
Track02.flac: OK
Track03.flac: OK
Track04.flac: OK
Track05.flac: OK
Track06.flac: OK
Track07.flac: OK
Track08.flac: OK
md5sum: WARNING: 1 of 9 computed checksums did NOT match

This Disc only has 8 tracks, so what's the 9th checksum refer to?
I get the same error when I check the file on my HD.
