[linux-audio-user] [OT] disk recovery problem

Hi there, It is a kind of OT, but I couldn't find any useful information, and I already wasted half a day on this problem, so I thought someone here would be able to help me. It seems like my partition table is messed up, and I am not able to mount all my partitions. For example, mount refuse to mount /dev/hda12 on any directory: when I do a mount -r /dev/hda12 /mnt/tmp, mount tells me that hda12 is already mounted, or that /mnt/tmp is busy. The partition is not mounted for sure, and I tried several other tempory locations, without any success. The "funny" part is that a fsck.ext3 /dev/hda12 doesn't give me any error when I check the filesystem (which let me some hope about the possible recovery). Basically, I think the problem is only coming from a wrong partition table, but I don't know how to recover the good beginning/end of the partitions (the partitions used for the OS itself seem OK, my linux is works flawlessly, "only" my last data partitions are not accessible anymore). All my partitions are ext3. Thank, and my apologies for the OT, David
