Mac G5 Hard Drive Partition Disappeared

We recently moved and when I set up my Mac G5 PPC at the new house, I found that one of the two partitions on the hard drive disappeared. Unfortunately, it's the one with all my files. I checked the disk utility and its not visible there.

Is there a way to find and recover the lost partition?

Mac G5 PPC
Dual 2.3 GHz processor
OS x 10.4.11

The easiest way would be to purchase a new drive

and restore all you files from your backup.

That said, I guess we be pretty sure that you do not have any backup solution in place, so you now have a decision to make on how much money you want to spend on this disaster.

$99 will get you a copy of Disk Warrior and $59.99 will get you an external 1TB hard drive.
From this point on you want to be using that internal drive as little as possible.

You didn't mention whether this is an iMac G5 or just a regular G5. If its a regular G5, then you will not need the external 1TB drive as a internal 1TB drive will suffice. The G5 has multiple slots for hard drives. (brings the price down too)

I suspect that the directory of the drive has become corrupted, thus hiding the partition, and the one thing that Disk Warrior does, and does really well, is repair hard drive directories.
If the drive has a mechanical problem, then you are looking lots of $$$ for a good recovery.

Do NOT try to recover lost files on the the drive that originally held them, that's what the 1TB drive is for. Writing to the damaged drive will just decrease your chances of a successful file recovery.

Thanks for the suggestions and info. I'm planning on replacing this computer soon, so I'm not sure how much money I want to sink into it. I have an external drive with most of the important files backed up, so I'm OK. I'll look around for Disk Warrior and decide from there if I would be better off just replacing the Mac sooner than I planned.

Follow up question on Disk Warrior

I'm working on the lost partition problem on my Mac again after setting it aside for the holidays. I found version 4.2 of Disk Warrior on the available hard drive and tried to open it to see if it could fix my problem. The "Authenticate" box opened asking for my name and password. I tried and it won't accept my password. Is there a way to get around this box or reset the password again? I didn't get the start up disk when I bought the computer.

Given the age of this machine,

it has not got the Recovery partition so the only way to reset the password is to boot from an OS X installation disk.
It does not have to be one that is specific to your machine but does have to be a retail version of OS X.

If you can beg or borrow one of those, you will be on the way to resetting that password.

Borrow a disk

I'll ask around and borrow a disk. Thanks for your help.
