    Hi there!

    Hopefully someone here are able to help me..

    My main developer-machine (powerbook G4)just died on me. It worked yesterday, but when i booted today i only got a grey screen. I have got a dual partiton, and OSX is running fine. My PFS-III-partition however running morphOS is dead.

    I'm able to boot from cd, and get the following errors on startup:

    PFS-III error request
    read error 45 on block 2
    make sure disk is inserted

    Device DH1:
    Alert:
    Wrong index block id

    Device dh1:
    Disk update failed

    .

    I tried pfs3Doctor, using repair i get the following message:

    Initializing
    Checking rootblock
    Read error
    Read error
    Read error
    ...
    Error: Rootblock could not be loaded
    Aborted


    I'm still able to see that the partition is 91% full, but can't access any files. I will have lost a serious amount of work if i loose this partition forever.

    so.. any ideas ? is there anything i can do? Thanks for your help!

    best regards

    Hopefully someone else from here will be able to help you with steps of how to recover your corrupted hard disk. I think all users (and specially developers) should always have a current (daily, or at least weekly) backup of all their data files. Secondly, I never fill up any storage device to anywhere close to 90%, as I believe this increases chances of problems on that drive or partition.

    I am sure this advice is NOT what you want to hear right now, but I wrote it to remind others, as well as yourself, to always back up your drives.

    kind of funny: yesterday my filesystem also crashed and I had to re-install... but it was a bit different from what you got.

    maybe the date, 2nd of March is to blame ...

    It really sounds like hardware or driver issue. Then you say OSX works fine on same HD. So strike that. Maybe PFS is trying to read outide of the HD limits.
    Then again, reading the rootblock should be at an absolute offset in most filesystems :) So PFS shouldnt get that wrong. Only guess is that partitioning
    structure is somehow broken. But then the OSX partition is working :)
    Maybe have a look with Mounter HDConfig to see if the partitioning looks weird. See if sizes of all partitions match what they should be. If "lucky"
    it might show itself clearly, if unlucky its only off by some small amount
    and there is no way to spot it unless you wrote down exact partition sizes
    somewhere :) Anyhoo, not sure how to fix that if this is the case anyway..

    Regular backups is the only cure. Especially on a system with no MP.

    Also, IIRC OSX has some tool to check HD SMART status. In case its the HD after all.

    Block 2 is the root block. And 45 is a hardware error.

    You should make a backup image of the whole harddrive, for example with dd on Linux or something similar which ignores read errors.

    Then mount the image, I think diskimage.device should be able to do this, and use for example pfssalv to rescue the files.

    Thanks for all your replies!

    I did find a backup of my recent work from the 17th of February. Copies of my older software was present on my backup powerbook, so i guess i was lucky this time :)

    Also, it kicked me into ordering a couple of ssd-disks to replace the old harddisks (they are probably way too old to be reliable anyway!).

    So i'm up and running again, and will use the next hours remaking the changes i lost :) (and start taking daily backups to my NAS from now on.
