Hi there!
Followed this forum for a long time and this is the first time I've ever posted, but I've lurked and read for atleast a month or two before I actually attempted any soft modding.
Anyway, I used
xboxhdm 1.9 and the Ndure 3.0 Softmod, Hotswapped after error 13, and it was all gravy, no problems, booted into UnleashX, everything worked peachy, but the lack of space was annoying.
Got myself a 200 Gig Seagate, which according to the lockDB, is lockable, so I went about backing up the E:/ Drive and The C:/ Drive and everything was fine, but I accidentally put them in the wrong folder in the
xboxhdm 
So, when I used the xboxhd tool, I didn't install the dashboard or anything, and I locked the HD using my eeprom that I backed up off the HDD, and I popped it into my xbox.
Error Code 21

Did a little bit of reading, error code 21 during a HDD Upgrade is usually caused by bad files or mis-copied files, so I figured I'd just start over, simple enough.
Remade my
xboxhdm ISO, with the eeprom still in the folder, but now, I cannot use the Linux Unlocker to unlock my HD.
It keeps telling me no drive connected, but, when I boot into my bios, my computer sees it in the IDE List, connected to primary master.
Anyone want to help me out?
