A partition or partitions are corrupted on one of the drives on my G4.
The drive is a Hitachi HDP725050GLAT80.
When I boot off the system CD, it can see two partitions, but not the
other three.
I have an older version of DiskWarrior (3.0.2) which also can see two of
the partitions, but cannot fix the problem.
Would a newer version of DiskWarrior (4.0) be able to fix the problem?
I downloaded a free program called Test Disk (7.0). Is anyone familiar
with that software?
So far, all of the partitions show up on the desktop.
The disk was partitioned originally using the free version (came with
the drive) of Intech Hard Disk Speed Tools.
I am thinking of buying the current version and seeing if they can
suggest anything.
Another thing I should do is to buy another disk of the same size, and
the necessary software, and back up the drive with the partition problems.
Anything I do must be in the $80 or less price range.
Thanks.
Neal Lewis

Disk warrior fixes volume catalog and index issues, not disk and partition issues.

i'm not super certain and Miiiight cause more problems than it'd solve but
there are partitioning tools in UbuntuMATE that should work on your
Powermac Model After you'd install hfstools (which can still be done in an
liveCD Session)

Hello!
You failed to give some vital information. Is this a bootable drive in a
Power Mac? Which version of Mac OS X are you running? Are the partitions
accessible at all?
Normally the Apple Partition Map (APM) is stored in the first 64 sectors
and if they are not corrupted the partitions should be available from
every OS that can read APM partitions.
TestDisk should be able to find partitions for a APM partitioning
scheme, but I personally never tried it. Someone else didn't either,
https://www.broes.nl/2008/01/restore-an-apple-partition-map/ , but has
found an alternative solution to reconstruct the partition table.
You say that all the partitions show up on the desktop? I would
definitely safe all precious files from the disk before I would try to
"fix" the partition table.
Which Power Mac are you using? Because if it is a Mac prior to the
Quicksilver 2002 then it's natural that you don't see partitions behind
the 128 GB barrier, due to LBA with 28 bits versus LBA48 with 48 bits.
See
https://4thcode.blogspot.co.at/2007/12/using-128-gib-or-larg er-ata-hard-drives.html
for more on this and why it is possible that you see the partitions on
the desktop after booting...
Good luck!

Bruce,
Thank you.
I wish it did.
However, that information puts me one step closer to a solution.
Thanks again.

Bruce,
A very interesting idea. I have been thinking about getting into Linux
and this may be the opportunity.
Which version of Ubuntu (or Fedora, maybe?) would run on a G4 PPC?
I'm game to give it a try, but would need to back up the disk that has
the problems first.
Thanks.
