Problem with TDK 1280b (T7S4 firmware)

The drive read/write all kind of CD±R/RW perfectly. But it can only read “white-face” DVD-R and can’t read “color-face” DVD-R.

But when i put it to other PCs, a Pentium3 and Core2Duo, it read the “color-face” DVD-R very well. I can’t understand why?

My mobo is ASUS P4P800-SE. I’ve update the firmware of mainboard to the lastest, clear CMOS setting, and reinstall Windows but still the problem. I’m wondering maybe there’re some option in the BIOS that make the drive can’t read color disc. What should I do? Thank you very much!

Might be a power supply problem, if it works OK in another system.

Really? Thank you i’ll try out
