Hit exactly the same problem. You have to use both drive f: and drive g: for hardddisks bigger than 250GB.
OK so I have an xecuter 2 chip, an upgraded HDD, xbox has been running fine for like a year.
Basically, I have F Drive enabled, G drive disabled, and everything has been working fine for the best part of a year. I put xvids and stuff in my F drive and watch them using XBMC.
Today I was uploading a couple of movies to my F Drive, using flashfxp while Unlesh was booted. The F drive is like 80gb or something, and it was getting pretty full (from what I remember it was almost full with these last couple of files, dont know if that makes any difference) There were no reported errors in FXP, so I flick the TV over to the xbox connection, navigate to XBMC, from within XBMC, hit my videos, F drive, and to my disbelief it was empty?!
Well I thought maybe I had deleted everything by accident, how I have no idea, but I restart the xbox to see whats happening and then this starts happening, a very long boot time of Unleash.. Like 1-2mins, the splash screen is fine, then after the xbox logo fades away it takes about 2 minutes for the unleash screen to pop up (This is also sometimes as quick as 20/30 seconds but its clearly something to do with the F drive). Everything works fine in the dash. I have HDD info showing on the skin and its reporting the F drive as:
F: 0.00 MB Free
If I goto the storage menu under the settings menu (Hard Disk Settings Options) the F drive is shown as:
Drive F 0.00MB/0.00MB
??
So where has my F drive gone?! C E X Y Z drives all are fine, there is the usual 4.881.63MB on E, 499.92MB on C and 749.89MB on X Y Z, just F has gone all wierd.
If I log onto the dash via FTP there is no F drive in the listing to browse into..
If I use the file explorer in Unleash X, F is shown as 0, same as D.
I just cant understand whats happened, I didnt even touch anything. Any ideas? I could do with salvaging what was on that partition
Thanks.
(BTW using latest Unleash and XBMC, bios im not sure about but like I say Ive been using it ages with 0 problems and its definately an X2 bios)
