I have a blank USB flash drive I want to put a new filesystem on. If I try adding a new partition it complains "No partition table found on device /dev/sdc". Creating a msdos partition table seems to work correctly, except that when I go to add a new partition it complains with the same error. What am I missing?
Ubuntu – Why can’t I create a partition table on the USB flash drive using GParted
Trying using Disk Utility in the Administration Menu (command line:
palimpsest) instead of gparted. You should be able to create a partition table with it or replace the existing one.
It's entirely possible they use the same libraries & access routines - if that fails i'd suspect your hardware is faulty.
