Hi all,

While copying a CD into harddisk, I got the following in the syslog (and
on the console):

The copy finished successfully. What is this? Should I care about it? Why
is it? :) (so many questions...)

I was copying copying from hde to hdg. dmesg is at the end.
The cdrom is connected to via a 80c udma66 cable to the first port of the
HPT370 on my Abit VP6 motherboard.

dmesg:
