One program I did not see talked about is testdisk. It is designed
to find deleted partitions. I have not needed to use it for real,
but I have deliberately messed up a partition table to see how well
it works. It does a great job on drives that have only been
partitioned and formatted once. If you have had different
partitioning sachems, you may have to pick out the correct
partitions from a list of partitions it finds. But it usually isn't
too hard.
Well I didn't mention it because I said:
anaconda [...] removes magic numbers from partitions superblocks
[...]
and
none of automatic "lost partition detection" tool could
find them.
I tried testdisk with a few different settings, none of them worked.
Only partition it was kind of able to detect was the first on (/boot)
and even there it messed up starting point (2046 instead of 2048
sector).
But yes, nevertheless, if someone "just" wipes out his MBR testdisk
would be very useful I agree.
