I am trying to format a new hard disk (and a USB-stick) using GParted. After successfully formatting the drive (to ext2, ext4, ntfs, fat16, whatever), GParted tries to reload the partition data and concludes that the partition type is "unknown".

I tried to use testdisk, which also seems to be confused about the state of the drive. It detected a 2GB partition to be 29GB big. Rewriting boot table data, recreating the partition table and others have not worked.

What is there left for me to try?

may be time for a new "stick" – Ringtail Jan 9 '13 at 5:31
@RickGreen-Turbo Really? Never mind the USB-stick, I am trying to do this on a brandnew 320GB HDD. Why wouldn't it work? I am guessing you misinterpreted my title, because surely you aren't suggesting I should just try it on another new hard drive...? – Earthliŋ Jan 9 '13 at 5:41
Don't know - why don't you edit your question to reflect that issue - I was lead to believe it was a thumb-drive. – Ringtail Jan 9 '13 at 5:51
