parted should handle overlapping partitions more gracefully

[Agostino Russo]

When partitions overlap, (lib)parted throws an unrecoverable bug error. It should be a warning you can ignore.

[Colin Watson (cjwatson)]

This may be a duplicate of bug 232175, but I'll need to see the user's boot sector to be sure.

(Please do not make this a general bug about any case where libparted fails to detect partitions. I am only going to deal with such problems one at a time in separate bugs. Unless you're the "Chechuty" user on the forums whom Agostino has been helping, please do not comment here; open a new bug instead.)

Rosen: Thanks for this. Are you the same person as Chechuty on the forums, who posted http://www.sendspace.com/file/i8oyeb earlier?

This partition table seems to be fine in and of itself, but unfortunately I also need to get the contents of the extended partition table in order to reproduce this accurately. It's quite some distance into the disk. This additional command should retrieve it:

  sudo dd if=/dev/sda bs=512 skip=193478656 count=1 status=noxfer | od -tx1 -Ax

(Be sure to type this in accurately! The skip= number is the sector offset of your extended partition table into the disk.)

[Rosen (rosen1991)]

Yes I Chechuty

The output of the command sudo dd if=/dev/sda bs=512 skip=193478656 count=1 status=noxfer | od -tx1 -Ax

"Error: Cannot have overlapping partitions." says parted, so not the same as bug 232175. Will investigate.

[Rosen (rosen1991)]

Ok!

If you need something tell me ;)

I'm having the same problem on my machine:

This was fixed some time ago; parted now just throws a warning that you can choose to ignore and try to repair the situation.
