Read before Installing New HDD
make sure your HDD works with the Xbox First
http://xboxdrives.x-pec.com/?p=statistics
ps… I have done this Many Many Many Many times and works 100%

if you can’t find the eeprom.bin look in E/UDATA/4541000d/000000000000/backup/
or E:\backup_linux
Or if you Used Krayzie’s Installer look in
E:/Dashboard/backup

(Note) If you used the Backup of your Softmoded Xbox Then to Resoftmod you MUST Delete the Save off Xbox HDD then Recopy a fresh one on the Xbox As that one is used

when it says (primary master) that means Master Cable look in Bios to see what is on primary master and put the HDD you are going to use on that one

To lockHD you need to go in to PC bios and set HDD to User not auto

How To Install A Bigger Hard Drive

Using this method you will not need to do anything to your original hard drive which means that if anything does go wrong you will still have an xbox 🙂

Needed Equipment/Software:

1) xboxhdm 1.9 http://www.smdepot.net/zzk/Exploits/xboxhdm_v1.9.zip

2) Torx 10 And Torx 20 Screwdrivers – To Open XBOX

3) A Spare/Blank PC Hardrive (Can be anything from 10 GB to 500 GB i use a 200g (you can set a Full 400gigs on F: )
(have test this and does work)

4) FTP Program (FlashFXP,Cuteftp,AceFTP, SmartFTP etc.)

5) A blank CD-R/W,DVD-R/RW and A CD/DVD Burner

Steps:
(Note) you DO NOT need to go to Backup in EVOX with Krayzie Ndure or Krayzie UXE)

1. On your xbox’s evox dashboard go to system utils and select backup. While your waiting for that to finish extract all files in xboxhdm 1.9 to your PC’S hard drive and open up the folder ‘linux’ in that folder is a folder called ‘eeprom’. Once the backup is complete, on your PC run the desired FTP program and access your xbox. Go to E:\ backup_linux\ or E/dashboard/backup/ and download a file called ‘eeprom.bin’ to the xboxhdm\linux\eeprom folder of on your PC’s hard drive. Then go to the root of your xbox and download the full folders of C:\ and E:\ (You can use F:\ to if you want it) to your PC’s hard drive to the xboxhdm\linux folder and overwrite the ones already there. Now in the root of xboxhdm is files named ‘make-iso-win’. You must run make-iso-win and wait for it to finish once it has finished. Now burn the .iso which was created to a blank cd-r/w/ DVD-R/w using nero or alcohol etc. When burning is finished shutdown pc.

2. Take out all other hard drives leaving a CD/DVD drive in and put in the hard drive you wish to make an xbox hard drive and set it to be the (primary master.) Boot up your PC and as it is loading press escape and set your PC to boot from CD. Now reset your PC and put the cd-r/w/DVD-R/w with the .iso you created on it, in the cd/dvd drive. You should be given a list of options. Choose Option 1 (by typing ‘1’) and press enter to boot VGA console with xbox-drive utilities (default). Type ‘xboxhd’ when it asks you for a login. Another list of options will show up, choose option 1 again (the one that says ‘Build a new Xbox HD from scratch’) and it will begin to format and write the partition table etc. If you put your C:\ and E:\ onto the CD then when it asks you about them type yes and when it asks you if you would like an F select yes, it is all pretty self explanatory. Now quit and reboot your PC. If this worked you now have a brand new nearly-usable xbox hard drive.

3) Now for locking the hard drive. When it boots from the cd agian, this time type ‘3’ and hit enter to boot linux with locking/unlocking utilities. Next, type in ‘lockhd -a’. It will now search for the eeprom on the CD and will automatically lock the hard drive. Now turn off the PC and take out the hard drive when it has finished locking.
(Note If HDD is locked you’ll see 2 Yes’s)
(Note security lock Is NOT you’re HDDs Lock security enabled Is

WELL DONE YOU NOW HAVE A BRAND NEW CUSTOM XBOX HARDRIVE!!!
