Did you get the wrong parameter? -c is for checking for bad blocks,
-n is to do a readonly check.
No, I jumped ahead and suspected that there is something wrong with the
disks. If all Patrick did is what he said he did, like you, I don't
see how he could have affected all three disks with gparted. So, I'm
thinking disk malfunction of some kind. The -c will check if there are
a bunch of bad blocks on the disk (blocks that can't be read), an
indication of a failing drive. It is read only.
You're right, though, that specifying -n as well would be safer.
Something just doesn't add up here, this is way too much damage for a
simple single command error.
