No password, it was an old 1 from a laptop i just put it in a caddy but everytime a connect, it says you must format drive I tryed it in a vu and works fine, I'll try that gpart
You could try to make it an external drive using an old HD enclosure, and connect it to a Mac or Linux box to format it.
You could also create a bootable CD with Hirens Boot CD (h**p://w*w.hiren.info/pages/bootcd) and use one of the Hard Disk tools to reformat or wipe the disk.
I have used GParted many times in the past, and to great success! If I were you, I would absolutely take Little's advice. The program is very easy-to-use, and can be found in all sorts of corners of the internet. Both paid and unpaid... However, that's a topic for another day. With that being said. You can find out more about the program here...
