I've done my fair share of XBox mods (I'd say I'm approaching 100) from mod chips, to TSOP flashing, and Soft Mods, so I'm no newbie. I've done searches and read many posts, but I can't find a solution to my problem.
I have a 1.6 Xbox with the stock hard drive that I Soft Modded with Krayzie's Ndure kit for Splinter Cell. No troubles, done it more time than I can count.
I decided to put a bigger hard drive in my 'box (80 GB Maxtor Diamond Max 16 - to be more specific). I did the same thing I always do when adding a bigger hard drive for soft mod: I put the EEPROM that was in the backup folder of the E drive created by the Krayzie Ndure kit in the EEPROM folder of XboxHDM 1.9 and made a boot CD. Booted my computer with the CD and locked the drive. I put it in my XBox and got Error 6. Okay, maybe I messed something up (highly unlikely), so I put the drive back in my PC, booted up the XBoxHDM and attemted to unlock the drive. No dice! What the heck gives? I couldn't unlock the drive with the same CD (EEPROM) that I locked it with! This has never, ever happened before!
I decided to try every other method of unlocking using utilities like atapwd, hdunlock, and hddisabl since I have the EEPROM and hddinfo.txt. Again, no luck.
Has this happened to anyone before?
I've burned the CD again 4 times, just to make sure that isn't the problem. I even formatted the stock drive to remove all traces of the soft mod like the shadow C drive and IMG, restored it to stock, copied my Splinter Cell save (the one I use for Raincoat TSOP flashing) back to it, backed up the EEPROM with Evox, FTPd the EEPROM back to my PC and tried again. I'm out of ideas.
I appreciate the responses and ideas from people. But I ask, please don't make suggestions about checking my Master/Salve/Primary/Secondary settings and disabling the drive in my BIOS, etc. Like I said, I've soft modded at least 20 Xboxs with larger hard drives using this exact method and have never had a problem before.
Thanks X-S members!
