XJ-HD166S DVD (can't read disk's?)

Hello,

I have the drive updated with the currect flashes. I am operating on XP (with all the current updates) here’s my problem.

When the computer has been left on for a period of time and I insert a CD/DVD ect into the drive, it “tries” to read it. The drive makes a “scraching” sound, and the drive keeps spinning. It revs high, then low, high then low. The only way to make the drive active again is to reboot the computer, and it reads the CD/DVD fine?? I have tried disabling the power management without any success…anyone have any suggestions??

Thank you
