My Samsung/TSST SH-224FB (6 months old) is installed in a Windows 7 x64 machine. When reading data from DVDs for copy/transfer to my hard drive, the optical drive spins up and down in short bursts -- approx 6 seconds each -- clearly not handling data at a steady rate. This makes all such operations extremely slow (DVD playback, eg movies, is fine). I've confirmed the Windows driver is correct, and the firmware (SB00) is the only version available.
Anyone have any ideas about this behavior? I've sent a note to Samsung Customer Service asking if it may be defective, but even if it is it'll probably cost more to ship than to replace. Meantime any hints/fixes appreciated.
