Hi, This is the sad story: Just got a new disk, wanted to install DOS on a small piece of it (last time I make that mistake), so I booted a DOS floppy. Without any input from me, the floppy comes up with "OK it looks like your configuration is incomplete ..." or something similar, and proceeds to FORMAT THE HARD DISK!! I go spastic and start banging keys and yelling, finally resetting when nothing seems to stop the monster. So the first part of the disk is history (I hope I am correct in assuming that the format starts with the first cylinder and works inward?), but the rest of the disk should be OK. In particualar, my /usr partition, which starts about 45 meg in, should be fine (please, please...). The problem is that I can't find that scrap of paper where I wrote down the partition info, so, My questions: How can I reconstruct a disklabel? Is the disklabel/partition info stashed in some other well-known location on disk? Do superblocks know about there own partition? Other partitions? How can I locate a superblock --- do they have some kind of magic cookie that I could scan for? Any and all help will be hugely appreciated!! Thanks Alan Alan D.
