I'm using a hard modded xbox with a 2 TB hdd since a couple of years without any problems. Now I'm modding another xbox for a friend of mine. The xbox is also hard modded (aladin) and has a 2 TB HDD (Western Digital) with a delock IDE/SATA converter (same configuration as my box).
For the initial setup (formating partitions, installing EvoX dashboard for FTP access) I used AID and later Slayers disc. But since two days I stuck in a crazy problem:
Initially the F drive has the full capacity so I used XBPartitioner 1.0 to resize F and G to about 260 GB and then use XBPartitioner 1.1 to resitze to about 927 GB (like in this tutorial. All went fine, no error, I see the correct size. But after rebooting / shutdown my F drive has still the initially size of nearly 2 TB

I repeated the hole process a couple of times, made a full cleanup, used another installer disc (slayer) and so on - and after reboot the initially size of partition F is back.
Hope anybody can help me. Thank you!
