Please include also TestDisk and gpart.


Usually I recommend the above two to people because based on user
feedbacks they do the best job in general. Unfortunately from all the
three basically only TestDisk is maintained and developed. Due to lack of
developer resources Parted is quite dead for over a half year (no patch
integrations, bug fixes, etc).

Will it be publicly available? ;)

Just FYI, you can create NTFS on Linux also with mkntfs from the ntfsprogs
package. The only drawback is that it creates NT4 NTFS and you can't use
sparse files on them. But just for testing partition recovery is enough
because the filesystem signatures and the crucial metadata layouts needed
to do the recovery are the same.

Do you have a 2.6 kernel? People report problems with those but usually
nobody has the time to care to fix them or add support. Let's hope it will
change in the future ... There were attempts to restart Parted
development/maintaince but they didn't get very far. Debian has a somewhat
patched Parted what fixes some issues and that's all so far, AFAIK.
