I know the sizes of the partitions, and have successfully gotten access to the 'a' partition, however, I can't seem to get access to any of the rest. There is a 32M 'a' partition, a 100M 'b' swap partition, a 100M 'e' partition, 100M 'f' partiton, 200M 'g' partition, and a 1021M 'h' partition. The problem lies in that I don't know if the swap partition is interspersed with these or not. I've tried many combinations of offsets and can't seem to get a recognizable superblock magic. I have dd'd through most of the drive, so I know that the data is there. Is there anyone out there that has been through this and knows how to reliably determine partition offsets and sizes by scanning the output from reading the raw device? Or is there some way to "force" a superblock magic? Thanks for any and all suggestions! -matt -- Matthew C. Mead mmead@Glock.COM http://www.Glock.COM/~mmead/
