But keep a copy of the partition around (as mentioned in the other posting), just in case you find a better way to rescue your files Good suggestion, Wolfgang. I did manage to recover a very small number of useful files that way. I didn't back up the partition because it is just too big to have hanging around taking up disk space. The reiserfsck man page says that if you have used a repartioning tool you need to find the correct start of the partition. I had guessed that it would be where it was before, but it looks like I was wrong. What I cannot find anywhere is any instructions on how actually to find the start of the partition. If anyone knows the answer then please post it. It won't help me, but it might help someone else with the same problem. Thanks Robert -- gentoo-user@gentoo.org mailing list

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

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. 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.
