I dont know if you used AR and a save hack but you should know how to hotswap. You can rebuild youre HDD with the below, i peiced it together to help out someone else should help you to. You could hotswap to rebuild (i know its my answer to everything). This way you dont need youre eeprom, but still back it up when youre done. This puts on UnleashX, if you want evox and xbmc put them in when youre doing step 2*. Dont put to much or youll have to burn a dvd.
#1 stuff you need
get this program xboxhdm_v1.9 from the file bank here
you said you used zzk hotswap mod so make sure you still have that around
get a cd-r or dvd or something you can burn onto
a program that can burn a iso (i reccomend imgburn
http://www.mrbass.org/dvdburn/)
#2
extract xboxhdm_v1.9 and open the folder named linux
you should see a folder named C, E, F and some other files
take every thing out of zzk hotswap mod and put it in the corrosponding folders ( c to C, e to E, ect.)
*(put youre apps in a folder named apps in "f" folder, including xbmc and evox)
double click on make-iso-win
and it will make you an iso named linux
#3
sart imgburn (or whatever program) and burn the iso to the disc you have
#4
restart you computer and hotswap like normal (make sure the cd boots not you OS)
if the hotswap was done correctly the HDD is unlocked
type 1 hit enter
type xboxhd hit enter
type 1 (say yes to all the questions)
you should be able to keep your F drive if you want (or even have it)
just say no to the questions about the F drive
#5
now after that finishes hit 8 to exit
when it is finished exiting pull the ide plug and hook your HDD back up to your xbox and power off
when you turn it back on the soft mod should be in the original state
thats it now get your EEPROM and you should be go to go
this worked for me so it should work for you
hope this helps, just find a different ftp program or at east upgrade it.
