Thank you!
I must have had a very bad day when I created my disks, and another bad day when I did not realize the problem.
I got several responses indicating that I had overlapping partitions on the disk, which was true. So I will spent the next night in reorganizing the disks.
Thank you very much!
Original post:
> We are having trouble in our Lab with some 9 GB disks. It is the second time now that on a 2 GB partition of this disk all the directory information dissappeared over night. The first time was about 3 weeks ago, and this morning _another_ partiton on the same disk was "empty". Running fsck got back all (? have to check this, but I think so) the files in the lost+found place with all the directory names substituted by those fancy numbers. I have a backup too, so the real damage is not the problem. But we have some very importent data and programs on this machine too...
