    Hey guys,

    Well last night i decided to give my mbp a clean install of snow leopard. After the reinstall I found out my external -Western Digital Mybook Studio 1TB (500GB partioned for timemachine and the other 500GB for my larger files and movies) only mounted the timemachine partition and not the other one. The other partion cant be mounted and cannot be repaired using disk utility. For some reason even the partition name has changed from 'My Actual Book' to 'disk1s5'. Both partitions are on Mac os journaled. Is there anyway i can recover my files and reuse the external? Please help me. :(

    Ive included what disk utility says:

    Verify and Repair volume "disk1s5"
    Checking Journaled HFS Plus volume.
    Invalid node structure
    Invalid record count
    Catalog file entry not found for extent
    The volume could not be verified completely.

    Volume repair complete
    Updating boot support partitions for the volume as required.
    Error: Disk Utility can't repair this disk. ... disk, and restore your backed-up files.

    tried tech tool but no luck. Using disk warrior now its been stuck at Step 5: Locating directory data. Speed reduced by disk malfunction: 1,227. That number seems to be growing from time to time. Its been a couple of hours.

    Disk warrior eventually finished after 6 hours. Was able to salvage the data. Brilliant software!
