I have been having this problem off and on for sometime, and was wondering if anyone else has had this happen? The problem is at some point during the write phase of the copy CloneDVD2 will just stop. No errors, but just stops and it takes a reboot to get it going again. This might happen anywhere during the write from 10% to 98% complete. Each time this happens I have a brand new coaster. System Windows XP, P4 2ghz, 512 ram, Optorite DD0201 at 2.6 firmware. Media is TDK +R, and Memorex +R both 4X. Sure would like to get this problem fixed, due to it is getting kind of expensive. Thanks for any help.
