I screwed up my partition table today and, like an idiot, I don't have a record of it. Are there any tools I can use to determine where my partitions were?
I have a 10GB IDE disk, hda. I had hda1 as /, hda2 as swap and hda3 as /home. The space was approximately evenly divided between / and /home and 256MB swap. Obviously / starts at sector 1. I determined, through trial-and-error, that / ends not before sector 748, but fsck doesn't complain if I make the partition too big. I don't think I have the size quite right because when I add 256MB to that and allocate /home I get errors about an invalid superblock. I can run debugfs on / and see all the data in that superblock. There must be some way (even looking at the raw bits on the disk) to determine where the partitions started prior to my screw up. It is (was) a woody system and I have potato CDs (ie rescue disk). Thanks for any pointers and suggestions. -D
