Ummmmmmmm................
My daughter has this habit of saying "be careful" AFTER someone slips, trips,
drops something, or just messes up in general. I'm not going to act like my
daughter. (suffice it to say, that "be careful is now treated as a joke
around here)
Have you tried formatting the partition? You just wrote a series of "0"s
across the partition...not as files, as raw data. You wiped out the inode
tables, superblocks, etc.
