[about fs recovery] > dd the whole disk off onto a file and mount it on a vnode? You might unfortunately is 1.6GB ... I need to find a bigger unit! > have to reconstruct the label and such, and using fsck's '-b' option actually an annoying thing with fsck -b is that I never know what to use as an alternate superblock number. 32, says the manpage, is an alternate superblock, but what are others ?
