I have a sony CRX160E. When booting up after memory check, and hang at
IDE checking (can't found the CD-RW device). The CD-RW door can open
and close itself, but i done nothing. Sometime BIOS and OS can't
detect the device. Sometime it operate itself and hang, i can't open
the door or the door open itself but can't close it. If by pass the
IDE checking, OS were auto uninstall the device, or software can't
found the CD-RW, making a lot of problem in OS. I try to check/remove
the IDE1&2/power cable, problem still remain. No differ when install
the device at other PC.No driver/firmware for this device.
