Re: Partitions corrupted on a drive
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.

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

Re: Partitions corrupted on a drive
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-larger-ata-hard-drives.html for more on this and why it is possible that you see the partitions on the desktop after booting...

Re: Partitions corrupted on a drive
i'm not super certain and Mght 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) On Thu, Dec 29, 2016 at 7:34 PM, Bruce Johnsonwrote: > > On Dec 29, 2016, at 4:55 PM, W.

Partitions corrupted on a drive
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.
