I tried this: dd if=/dev/zero of=/dev/sdb bs=1M count=1 Now the KDE partition manager in Linux shows 1 MB unknown device as sdb, and I can't even create a partition table. I never seen anything like this, but sdb disappeared from fdisk and tons of /dev/ram appeared. Full terminal output is here: pastebin.com/tg09qeJr
