[gentoo-user] Accidentally reformatted my EVMS root partition. Any hope of recovering data?

[Robert Persson]

I have, much to my intense surprise, managed to reformat my root
partition unintentionally. It was an EVMS native reiserfs volume, but
now it is a normal xfs partition. I haven't, as far as I am aware,
written any files to it since the unfortunate accident.

The tool I used to create the xfs partition was a non-standard, and
quite possibly inferior one with non-standard behaviour. It is also
likely that the xfs partition ends at the 128gb (i.e. 137gb) point on
the disk due to the circumstances in which it was created, whereas the
original reiserfs partition extended beyond the 128gb point.

Is there any possibility of recovering some of the data (there are some
family photos and a few other things I would very much like to retrieve)
or should I just put it down to experience?

Many thanks in advance
Robert

P.S. In case you are wondering how I managed to do this, it was like
this: I need to run a video editing application and one or two other
things in windows 2000. The crossmeta virtual file system drivers
sounded like a good way of sharing the work areas between windows and
linux, especially given the unreliability of ntfs even in windows.
Unfortunately the crossmeta stuff is very poorly documented. Quite apart
from anything else, there is no indication that the drivers just don't
actually work at all, hence lots of pointless troubleshooting and a
boundless potential to create much bigger problems. Add to this the
unfamiliar device naming scheme of crossmeta, and the fact that windows
2000 doesn't, by default, support large drives, even though the disk
manager behaves as if it does, and you have a recipe for a very big ****
up. Honestly. How could I pass up such a splendid opportunity?
