Seems I am having a problem with my SuperDrive. Whenever I insert a DVD, CD, whatever, Mac OS X (10.5.1) pops up an error that says, Disk Insertion: The disk you inserted was not readable by this computer. It gives the option of Ignore or Eject (if you leave it it just ejects for you). I also tried my system disk it said it was a blank DVD. I figured it may be an OS issue, but restarting the computer with the system DVD in the drive doesnt boot to the DVD, and instead OS X just spits it out once it has loaded. I reset the PRAM and tried booting with option held down to select a boot device, but the drive didnt appear. System Profiler is giving incorrect information about the drive: LATSHITADVD-R TJ,825D: Model: LATSHITADVD-R TJ,825D Revision: FAND Serial Number: Detachable Drive: No Protocol: ATAPI Unit Number: 0 Socket Type: Internal Low Power Polling: No I know the drive is a Matshita, not a Latshita, and Im pretty sure it used to have a serial number and a revision *number*. System Profiler says it can burn discs, Disk Utility says it cant. Disk Utility also calls it a M@TRHHT@ DVD,R UJ-834E obviously not right. I read that it may be an issue with the ATA connector (since it is throwing up incorrect information). Of other note, System Profiler reports sizes when disks are inserted (my 10.4.0 Tiger DVD is reported as 2.51 GB, if anyone wants to confirm). I tried two drive cleaning CDs, but they didnt seem to do anything (in fact, the first one caused Mac OS X to completely freeze). The computer is a Jan 2005 rev. PowerBook G4 15, 1.67 GHz, 1 GB RAM (one Crucial DIMM, one Apple DIMM), 128 MB VRAM, 80 GB (Hitachi) HDD. Clean install of Leopard. Im guessing my only option is to bring it in to the Genius Bar but if anyone has any ideas that would be greatly appreciated.
