The only thing that might help you is "and Ive done this" If you did a backup with evox and saved it in your computer "You should have this 5 file in you Backup Dir.Bios.BIN , Disk.BIN , Eeprom.BIN ,HDDKey.BIN , HDDinfo.txt.
I copyed this from the Evox tuts......
Locking the drive
Start by making sure that you can access the Xbox via your Network. Also be sure that you have a working bootable DVD/CD-RW that you can using to access the Xbox if you make a mistake.
If you ever accidentally make a mistake in renaming a file or in the evox.ini file youll need this disk to recover from problems.
You should also have a full backup of the C: & E: partitions of the Xboxs hard drive for safety.
I cant stress this enough! Burn it to CD and put it away.
Since the new password file for the hard drive will be written to the same folder Evolution-X is initially run from, Evolution-X itself must be booted from the hard drive. You cannot use DVD/CD-RW.
With Evolution-X installed, select the Backup command from the menu. You will see a sideways smiley face to let you know that the files were created in C:Backup.
Use FlashXP to copy over the C:Backuphddinfo.txt file to your PC and print it out. Youll need the hardcopy later.
The file will look something like this:
Disk Serial Number : "WD-WMA8C1313646"
Disk Serial Number : "WDC WD1200JB-00CRA0"
HDD Key : 65:fd:29:ca:25:4d:78:cb
f4:41:f7:b8:c3:69:15:0f
dd:dc:97:a9:00:00:00:00
00:00:00:00:00:00:00:00
On the page you printed write down the HDD Key numbers in this format:
65fd29ca254d78cbf441f7b8c369150fdddc97a9
omitting the zeros and the colons. This is the actual password that the Xbox will use to unlock the drive, and that you need to utilize to lock it with.
Shut off your Xbox, unplug it and remove the hard drive from the machine carefully. You should already know how to do this.
The drives arrive from the factory jumpered for cable select. Make a note of how your working drive is currently jumpered as you need to restore the Berg jumpers back to the same settings.
On your PC create a DOS floppy boot disk, preferably using Windows 9x or below. Make sure that there are no IDE/CD or SCSI drivers installed and that Himem.sys and any other memory managers are not on the floppy.
Copy the following files to the floppy.
ATAPWD.EXE
HDLOCK.EXE
HDUNLOCK.EXE
There should be ample space left over for text files on the floppy when you are done.
Connect the drive you removed from the Xbox to your PCs PRIMARY IDE channel. You may want to remove your existing drive from the IDE cable for safety.
If you have no other drives on the primary channel cable, jumper the Xbox drive to be only drive or no other drives present. If you do have another drive on the IDE cable jumper your new drive to be either MASTER/with slave present, or Slave accordingly.
Dont forget to provide power to the drive.
With the drive installed boot your PC up from the floppy you created
