    I am trying to recreate partition map for one of my firewire drive that has partition or directory information lost. I used testdisk to find partition information, start and end point, and it asked me to re-create same partition by using pdisk, problem is when I use pdisk, it said it does not support Intel mac, and always gave me:

    Error message: No valid block 1 on '/dev/rdisk0'

    All my partitions are HFS+

    I guess I need a tool that works for Intel mac not ppc to recreate partition?

    please help.

    ok, I managed to find out fdisk - is probably pdisk version in Intel Mac, but somehow, I cannot use fdisk -l to retrieve drive list... there is no -l in param... how can i see the drive list?? I could use pdisk -l.

    Why are you going all around Job's barn? Just use Disk Utility.

    disk utility won't show jack if your partition table is fubar.

    fdisk -l is the correct command, but again, if you've zapped the partition table, it won't show anything.

    i have done what you are attempting to do before, but for the life of me i can't remember exactly how i did it and it was in 2007 with the first intel builds. googling should turn up enough information...

    [edit] actually it was 2006. how time escapes.

    a quick search indicates that i made use of the tools Testdisk and PTedit

    you haven't fully explained your situation, but if your disk was a single partition, it shouldn't be too hard to figure out the correct numbers, create a blank partition and change the partition type to AF.

    will try to help as i can.
