did you actually _format_ it, or just repartition it? I see three possible options: 1. repartition it, hoping the filesystem has not been touched 2. run an undelete tool on it (don't know if they exist for reiser, certainly not for ext3 3. give up! If you "formatted" it, ie wrote "zero's" all over the place (or whatever a format does), then good luck, you'll need an "undelete", if there is such a beast for reiser. If you just repartitioned it (ie. wrote to the partition table that it was now an xfs instead of reiserfs) and you've done nothing else, not even mounted it since, then you _should_ just be able to use fdisk to redo the partition table. Use caution! I'd back up the drive with dd or something first, just in case you screw it up. repartitioning doesn't necessarily screw with the actual data on the drive - just the partition table. I once blew away my partition table by mistake, and rebuilt it by trial and error by guessing how big the partition where from memory, and then mounting them to see if I got it right. Of course, if you've run anything like mkfs over the partition then you're probably screwed. > The tool I used to create the xfs partition was a non-standard, and > quite possibly inferior one with non-standard behaviour. so long as it created the partition without mkfs-ing it! > P.S.
