I use a BenQ 1620-Pro, with Philips DVD+ media using Nero Tools. Now i use my dvd burner primarily for back-up of my files, and to save precious HD space. I just burned some video files into a dvd, and filed it away. Later on, i had to re copy some of the files to my HD, and i couldnt copy about 4 out of 10 files, because of some cyclic redundancy error. Now my questions:
1) What does cyclic redundancy error mean? What caused it? Is my media worthless? Is my pc too slow? Is it because I had other programs running while i was burning (programs like bittorrent and DC++). How do i avoid seeing this error in future sessions?
2) As stated above, i use the burner primarily for back up. Is Nero the best program to use in this case?
I'd just hate to lose some of my backed up files to this cyclic redundancy error thingy (yes, im a total noob). ANy helpful advice would be greatly appreciated
