This is the next morning .. problem came back. I had written yesterday's post about blowing out the dust from my Super drive and it worked, I successfully burned 2 dvdr+ disks and they verified.
I rebooted and tried another disk (Verbatim) and got the "error 0X80020022 because communication to the disc drive failed". I sprayed the inside of the superdrive again with compressed air and tried two more times. Each time the burning began and then failed after different duration of the burn. The last session I tried, the disk burned but then failed to verify. The only way out of the situation each instance was to hard boot the computer. I repaired my permissions after each hard boot.
I tried a Sony dvdr+ disk and it immediately failed. I know the Verbatim disks are OK because I am using them on the PC with no troubles (as well as the Sony), and the two successful disks I burned on the Mac were from the same Verbatim spindle.
Driving me nuts as I have been burning disks on this computer for years without problems.
It must be really, really dusty in there or there definitely is something to a software issue. I have another Superdrive from my old G5 iMac, the one that has the bursting capacitors on the logic board which is another Apple horror story. I may try and salvage that one and swap it but if the issue is more to do with OSX itself then it's probably a waste of time.
I will try and clean the lens with a lens cleaner first if I can find one.
