Partitions Not Shown, but Exist

Apt Quadruped · 12-05-2007, 05:29 PM

Alright, it appears that after I recovered some deleted partitions by using testdisk I can no longer view my partitions with some necessary programs. I can't view partitions in Gparted or the partition manager for a Debian system install. However, fdisk can detect my partitions perfectly. I can run all my OS's fine (at the moment Gentoo and Windows). Any suggestions?

How do you know that fdisk is detecting the partitions "perfectly"? What is the output from fdisk -l?

What do you mean that you can't view partitions in Gparted ? Do you get an error message? A crash? A blank display? What?

I have seen Gparted get confused when partitions overlapped. I have seen testdisk recover old versions of partitions and build a partition table that has overlapping partitions.

I have seen operating systems work with these overlapping partitions...for awhile. Then one day, something gets overwritten, and the resulting crash is spectacular.

When I say perfectly I mean that it can delete, detect, and make partitions without error. Here is my output from fdisk -l. (displays the partitions correctly)

In Gparted and Debian's partitioner they believe that there is no partitions, just unallocated space. I've never had a problem with either of these partitions before, until now.

That partition table looks fine. I see no problem with it, and have no clue why Gparted wouldn't see it. I have never worked with the Debian partitioner.

Try starting Gparted from the command line and see if you get any useful messages.

By running Gparted I get the following message.

Code:
