Howdy, I've just given my LiteOn 48x24x48 CD-RW to my dad and he's bunged it in his computer to find that when he copies lots of files off a CD it gives an I/O error. It's the master on the secondary channel with a CDROM as the slave. We've tried making it the only CD/DVD drive in the computer as the master but it still does it. His comp is a 1.7GHz P4, WindowsXP, ... Does anyone have any ideas on how to fix it ?
