Before flashing the tsop I had a M8+ bios on a Matrix modchip, now I have a IND bios. The problem appeared after a reboot when I was messing with the hd through Xplorer360 on my computer.
At first I thought it was hidden or maybe inactive, but as gparted is showing the hd as empty I don't know how to check that, maybe Xbox Linux?
That partition was full of games, so in fact what annoys me is to have to backup again all of them, but there's no loss of data. Is it possible to format F through xbpartitioner or do I have to do it with another program, maybe with EvoX?
Thanks anyway for the tips.
