So I opened up gparted, formatted the partition as ntfs, then reformatted it to ext4 again.
A format doesn't erase blocks, it only writes a few structures at the start of the disk. Mostly. If you want to do something that clears entirely the disk, just overwrite it with zeroes: dd if=/dev/zero of=/dev/sdb5 just be careful not to write any typo: it will zero anything you tell it even if wrong. -- Cheers / Saludos, Carlos E.
