What makes you think it's a software problem?
Use ImgBurn and check tools->Filter Driver Load Order. That will let you see filter drivers attached to the CDROM class... if there's nothing suspicious there, it's most likely not a software issue.

well i thought it may be a s/w issue because a) the drive still reads b) i updated the chipset drivers in between the last working burn and this problem. c) hope.
I am starting to believe that the drive is just dead though... I can't find my live CD to test it under there. and after flashing the drive ImgBurn gave me this:
ImgBurn

DeviceIoControl(FSCTL_LOCK_VOLUME) Failed!
Device: [0:0:0] Optiarc DVD RW AD-7170A 1.04 (G:) (ATA)
Unable to lock volume for exclusive access.
Reason: Access is denied.
Hint: You've got another program running that's using the drive, close it and then click 'Try Again'.
though nothing else was running nor should have been using the drive, so i told imgburn to ignore exclusive access in the settings and it gave me :

etc etc etc...
i looked @tools->Filter Driver Load Order and it looked OK to me, so i guess I'm going to save up for a new drive. are lite on good?
