Can you use xbhdm to make a bigger drive work on your xbox, (well it is called xbox harddrive maker

)
It's not what I know really I was going to upgrade my HDD I found one out of a old pc then I found out it was a 4GB (a bloody paper weight) so I didn't bother research it
As for the thanks button it doesn't appear untill you make 5 posts, but could you do me a favor could you remove your thanks from the post above and give thanks on the original post of the tutorial just so people know it has been used and it works
I did find this info for you
This is purely Ctrl+C and Ctrl+V
I haven't tried it myself (yet) and can offer no support to any one who does (yet)
Xboxhdm For Dummies - Scenyx Entertainment Community If you have Xbox LIVE, you CANNOT just upgrade the hard drive. You will be permanently banned from Xbox LIVE if you do that. The reason being is Micro$oft matches/pairs your Xbox's EEPROM to your Hard Drive's Serial Number. Your EEPROM is your Xbox's unique ID, your "fingerprint" persay. It contains all the information like your serial number, mac address, region information, video settings, and hard drive settings. Now, if your Xbox has ever been on Xbox LIVE, your EEPROM has been married to the hard drive. If the marriage is broken (EEPROM changes or hard drive is replaced), then the Xbox gets banned from Xbox LIVE. You can read more about the marriage theory Here.
The only way to upgrade your hard drive and still be able to go on Xbox LIVE is if you buy a new EEPROM that has never been on Xbox LIVE. After upgrading your EEPROM, you will be able to logon to LIVE with a new hard drive because the Xbox appears to have never been on Live, and the hard drive has never been on Live. In MS's eyes, you are a brand new Xbox connecting to Live for the first time.
You can buy a new EEPROM in the B/S/T forums.
QUICK TUTORIAL FOR UPGRADING HARD-DRIVE AFTER ALREADY SOFTMODDING STOCK DRIVE VIA NDURE
1) Get xboxhdm and extract it.
2) Use ConfigMagic to extract your eeprom. FTP this to your pc, rename it to eeprom.bin, and put it into the /eeprom folder of xboxhdm.
3) Go into File Manager on your xbox, navigate to e:/ndts and run the default.xbe in there. This will load an altered version of unleashx with full access to C and E.
4) FTP your C and E drives onto your pc and put them in the respective folders in xboxhdm.
5) Run make-iso-win in xboxhdm and burn the iso with alcohol 120% or any other alternative image burning software.
6) Place the xboxhdm CD in your cd drive and then shutdown your PC. Disconnect your hard-drive. Connect your new hard-drive to the primary master and then boot up your computer.
7) When xboxhdm loads up choose option 1, then when it's loaded type xboxhd. Choose option 1 again to prepare xbox hard-drive from scratch. Answer Yes to all the questions and when it is finished hit reboot.
8) Now when xboxhdm comes up choose option 3, and then once this is loaded type 'lockhd -a'. This will find your eeprom.bin and lock the hard-drive.
9) Your new hard-drive is now ready to put into your xbox and will be an exact mirror of your existing xbox drive but obviously with a lot more free space.
Q: Xboxhdm is telling me my drive is frozen, what can I do?
A: This seems to be a BIOS issue and happens more frequently on store-bought Intel-based computers. If your drive is showing up as frozen, do this. When you’re booting up your PC, hit the Pause Break button on your keyboard. Now - boot up your Xbox, let the drive unlock, and do the hotswap. Hit the Pause Break key again and it should work fine.
Q: How can I uninstall the softmod?
A: Since you backed up your C drive before installing the softmod, you can "reload" the backup and go back to a retail state. To do this, launch Ndure Toolset and choose Restore From HD Backup.
