I had an ext3 partition. I ran a dd command like this:
dd if=/dev/urandom of=/dev/part2 bs=1024 count=15000 seek="various values"
various values are basically 0, 15000K, 30000K etc.
The point is I ran the dd command on the entire partition.
Now the partition won't mount. I get an error "Can't find ext3 partition on ..."
What exactly happened to the partition? I know it got corrupted, but what exactly happened? As a clue
fsck /dev/part2gives "The superblock could not be read or does not describe a correct ext2 filesystem."
How do I format it back to ext3?
