[Bug 48229] Re: Partition table destroyed when resizing NTFS

[Szaka]

Parted  (what gparted uses for partition table manipulation) doesn't
touch NTFS at all so it can't destroy it. What it did was that it
changed the NTFS partition start to an incorrect place in the partition
table, so it became completely inaccessible.

Unfortunately neither gparted nor testdisk can still find the NTFS
partition reliable, so I wrote a simple utility two years ago which
finds all possible real partition starts. It worked fine in the past for
everybody. It can be downloaded from:
