Hey. Recently I wanted to install direct cd for formatting my CDRW drive to drag files into it from explorer. It was a very old disk for my HP 8100. After that when I try to drag large files from CDs to my HD (tried both cdrom drives and tried it on both my HDs) I get Cyclic Redundancy Check errors. These CDs worked before and work on other computers. I went to device manager and removed both drives, and readded them both. Still no dice. I reintalled XP. I removed the HP software also. I know the CDs are in fine condition. Any ideas? Thanks.
