hi… maybe somebody can help. i had a problem with my writer. pc hangs when i try to read previously written discs. and also getting calibration errors when writing… (using cheap cdr) :frowning:

although there are some cd’s that are working fine. i checked on a burned cd, i can barely see the burn. i will try cleaning the lens of the drive.

i want to ask if light burns can still be fixed? and will upgrading firmware solve this?
