Best CD reader for on the fly copying

[Mini Maggit]

HI!

Sorry for the offtopic but I notice problems when doing some backups from DVD to the hard drive...

My current set up:

Primary IDE connector: IDE HD1 (UDMA66 Quantum) as master and IDE DVD-ROM (Creative Encore 6x) as slave.

Secondary IDE connector: IDE HD2 (UDMA66 QUantum).

Problem comes when I tell SmartRipper (DVD ripping program) to copy files from DVD to HD2. Computer freezes every 10 seconds, but it copies everything fine. I just can't multitask when ripping a DVD to HD.

Ideas??

Thanks!
