CRC Errors on copying files

[rpmzzz]

Thanks for your answer, I will try that. Something else unrelated to hoster program if anyone wants to take a shot at it. I have backed up my DJ drive which is G to my backup which is E, both externals, a couple of times now using the copy this file task on my computer, and keep having a problem. I have about 13,000 DJ Song or about 65 Gigs. Somewhere during the copy process it will stop and come up with a cyclic redundancy error. I then have to go through a process to find where I was and skip that file and then continue process. Doing this I am however losing a handful of songs everytime I backup as it is always a different song, and if I try to copy it over even as a single file same thing. It is however fine at the source as far as playing, but if anything happened to that drive it would not be on my backup.... what to do.....???????? Thanks again.
