I've been using DiskStudio for a while, a really like the program. I've used it to jumble partitions on my PowerBook, as well as on other PowerPC based Macs.
My most recent adventure with DiskStudio was re-partitioning to make space to install Ubuntu 5.10 on my PowerBook. So, I had DiskStudio resize my OS X partition by 10 GB, and I installed Ubuntu in the 10 GB space.
Now, I've decided that I don't want Ubuntu any more. I blew up all the Linux partitions completely. However, DiskStudio deems my hard drive "unpartitionable". It would only show one partition, my OS X partition, before and after I had deleted the Linux partitions. I would really like to resize my OS X partition, or at least be able to partition the free space, so it's useable! However, with everything I've tried, DiskStudio still says that my drive is "unpartitionable".
I have been able to create, delete, and resize partitions in the past, using DiskStudio, with no problem.
Is there a way to fix this?? Thanks.

Re:Drive Deemed "Unpartitionable" Suddenly - 2006/04/22 07:33I will have to ask about Linux partitions on Monday, but as far as I know, the program deals only with HFS and HFS+ volumes.
On what type of volume was Linux installed, and how was that volume created?MicroMat Inc Makers of TechTool

Re:Drive Deemed "Unpartitionable" Suddenly - 2006/04/22 10:41Here is how I went about installing Ubuntu Linux on my PowerBook G4:
I booted my system using the DiskStudio CD
I had DiskStudio resize my OS X partition down by 10 GB.
DiskStudio wanted to create a partition in the non-partitioned space, so I created what it called a either Linux or Unix partition (I don't remember exactly) to fill the 10 GB of nonpartitioned space.
I rebooted and booted off the Ubuntu Linux install CD. Ubunt deleted the 10 GB partition created by DiskStudio, beause it needed two partitions, one for swap space (swap) and one for it's root (/). I believe the root partition was formatted as EXT3.
Finished the installation process. Ubuntu Linux installed, I believe, they yaboot bootloader so I can choose between OS X and Utunbu upon boot.
Here is how I went about trying to remove Ubuntu Linux on my PowerBook G4:
I booted my system using the DiskStudio CD
Whe the DiskStudio software was done loading, it only displayed the OS X partition and showed it as full. It also displayed "disk unpartitionable". I had about 10 GB free at that time.
I booted back into OS X thinking that maybe I would need to free more space. I managed to free a total of 13GB of space on my OS X partition.
I boot using the DiskStudio CD again, and it still shows the one partition, it being full, and deeming the drive "unpartitionable".
So, getting a little desperate, I decided to boot using a Linux LiveCD, and I remove the two Ubuntu Linux partitions (swap and root) manually. I'm hoping that DiskStudio would then see the unpartitioned space and be able to utilize it.
Unfortunately, this did not work. DiskStudio still only showed my one partition, as full, and still deemed my disk "unpartitionable".
I hope this helps. Thanks!!

Re:Drive Deemed "Unpartitionable" Suddenly - 2006/04/22 11:12I am sorry that you are having this problem.
I should have mentioned in my first posting that the current version of Disk Studio can delete UFS volumes created by Apple’s Disk Utility. The first release of Disk Studio could not.
By using a program other than Disk Studio to delete a volume, you have modified the partition map in such a way that Disk Studio is no longer able to use it. I will pass your experience along to the beta administrator for Disk Studio, so we can warn people not to do this.
Thank you for providing a clear and detailed description of exactly what you did. I doubt we will be able to solve this problem for you, but with your description we might be able to duplicate the situation and see if a future version of Disk Studio could deal with it.MicroMat Inc Makers of TechTool

Re:Drive Deemed "Unpartitionable" Suddenly - 2006/04/22 11:33Is there by any chance a utility I could run that would possibly fix the problem? If not, oh well.
I'm not sure what version of DIskStudio I have. I do know that I ordered it when I was at Macworld in 2005. Are we eligible for upgrades?

Re:Drive Deemed "Unpartitionable" Suddenly - 2006/04/22 21:13You can download the Disk Studio 1.1.1 updater. If you have another bootable device, you can run Disk Studio from that device. Making a new bootable CD is a task that requires Clone X 2 from www.tri-edre.com, and is not something we can support.
I doubt that any program is going to be able to fix the partition map in such a way that Disk Studio will be able to modify it.
You are doubtless aware of the fact that Apple’s Disk Utility does not allow the user to add or remove volumes without reformatting the entire device. Each of the third-party utilities that provides that feature does it in a way that makes the resulting partition map fully usable by the operating system, and the resulting volumes fully usable by the operating system and all disk repair utilities. However, the modifications made to the partition map by these third-party utilities differ somewhat in their approach, and the resulting partition maps are not compatible with the other partitioning utilities.MicroMat Inc Makers of TechTool

Yes, I am fully aware of that. Hence why I purchased DiskStudio .
Thanks for all your help.
