    Default How to recover from DVD-R ???

    It's a udf formatted DVD-R with a VIDEO_TS folder in the root
    full of jpegs that plays fine on my Philips DVD-724 standalone.

    Surface looks unblemeshed.

    Tried to mount in two macs:

    1) G4 with a stock superdrive Pioneer DVR-103
    2) G4 with stock Pioneer DVR-104 - both with current firmware upgrades.

    Tried with System 9.2.2 with all combination of foreign file access
    extensions
    and even the old Adaptec udf driver, speed tools, cd/dvd kit, and more

    - keep getting the old "This disk is unreadable by this computer.
    Do you want to initialize the disc?" message.


    Tried with System 10.2.6 - no go

    Tried VPC 6 running Windows 95 - crashes

    No matter what I can never keep the disc in the drive,
    or keep it from crashing things, or get it to show up in a
    data recovery program (i.e. Norton's "show missing discs")
    so I can scavenge the jpegs off it.

    DVD rescue looks like a growing field over on the PC side of things,
    but how about us mac users? Anyone?

    This is just a wild guess, but maybe you can connect
    your Philips DVD player to your Mac and read the files
    off the disc that way.

    sounds like the drive doesn't like the disc. have you had problems with
    other discs of this brand in that drive? try the disc in a non-pioneer
    burner, like a plain ol dvd rom reader.
     

    cd and dvd rescue is pretty weak on the mac side....

    As weird as that sounds - I'm considering that option.

    I assume I would need a video card and read from the RCA video or the
    S_Video output...

    If luck was on my side an app like iPhoto may pull them off...

    You say that you tried this with 9.2.2. Have you tried it with OS X

    on either my iMac, my G4, or my G3 PowerBook running 10.2.6 -- the iMac
    has the DVR-104 and the other two have DVD-ROM drives.

    While the next is something you probably won't want to hear, it is
    pretty much the current state of the Mac world: People continuing to
    use pre-OS X MacOS releases are unlikely to have _new_ capabilities
    added. The development efforts of almost every company are directed at
    OS X.

    Oh i know that... but sometimes older stuff works (often in the case of
    licensing issues, learning curve, etc.)

    But yes, I tried 10.2.6 - don't have panther yet.

    I actually could see the disc using the new version of Data Rescue X
    (which looks very promising) , but it fails trying to recreate a
    partition (I/O error), and thus has no files to recover.

    I can play everything else in the drive including other dvd-r data
    discs; in fact I thought about force ejecting a good udf-data disc,
    then inserting the bad one, but i can't keep the good udf disc icon on
    the desktop... can it be done?

    I've never been beat by a bad disk yet... but it's looking grim.
