This is something like a Cyclic Redondancy Check i.e. a calculation on
written bytes (and the result itself is written). At read time, the
calculation is performed again and if the result is not the same, this is
because the bytes you read are not those who were written.
So basically it would mean that for some reason, you can't read correctly
the file back (damaged support or whatever, as it doesn't work here with a
particular machine, the drive might be a bit more sensible to external
conditions).

Hi
I get CRC-errors when I do System.IO.File.Copy from a dvd-r disc to a d:
drive. It works on many computers but not this one laptop.
best regards
