Comment 5 for bug 231575

I can confirm this problem with my hardware.

Lite-On DVD-RW SHW-160P6S
MSI K9VGM-V mainboard
AMD Athlon X2 5200+
SATA hard drive

The dvd drive will work just fine for many hours and then stop working for no apparent reason, even when idle. It then becomes inaccessible until reboot. Once the errors begin, the driver starts dropping the access speed until it reaches PIO0. Here are my messages from last night...I wasn't using the machine when the errors started appearing.

The drive is only about 1 year old, is this likely a hardware problem?
