I used TestDisk to find the partitions.

Then I used pdisk to make a new partition table.

I checked the results with Drive Genius 2.

What I found was a very small partition that had not shown on TestDisk.

Each partition on the drive had an Apple_Space between one partition and the next.

I have a Seagate Barracuda 750 Gb hard disk that has 5 partitions. An accident with some OS 9 based software damaged the partition table.

This is the first time I am trying to use TestDisk. So far I've tried it but not sure I have used it correctly so I have not implemented the results.

Pursuing my rather old topic, I have the Firmtek 1V4 SATA controller in place and Firmtek 1SC1 adapters that allow a PATA/IDE drive to be attached to the 1V4 SATA controller.

The G4 AGP Mac sees the 1V4 controller as a SCSI drive.

SCSI drives are not restricted to LBA 128 Gb or less on any Apple ...

M. Grenier,

I have tried a different approach.

I have installed a PCI card that has an LBA48 compliant controller. The computer sees the card as a SCSI card.

Even Macintosh computers that are not LBA48 compliant for ATA drives (and also run OS X) can still see drives that are larger than 128 Gb ...

If I put the drive into an LBA48 capable Macintosh, then TestDisk might be able to reconstruct the partition table? Or is that ability (to find and reconstruct the table) restricted by how the partitions were made originally?

Thank you.

So it appears that it is not possible to use TestDisk to find or to restore the partition table? I believe I have the correct understanding?

Thank you.

Before I go any farther I should make certain that TestDisk will or will not work on my G4 Sawtooth Macintosh. It is a non-LBA48 computer. So, (as I understand it) boot information must be in a partition that is 128 GB or less.

I have had a partition failure on a 750 GB Seagate hard drive.
