Sorry for the delay. Life and stuff got busy. Im trying to locate some of the files to make this a bit easier. You can follow the guide bellow if you are in a hurry. The most important thing is to create an undo file. Because that is the main thing you will need to change. Use a 20Gb hddss.bin to actually do the flashing at first. You can find those just about anywherehttp://digiex.net/guides-reviews/consol ... -slim.html
Restart your pc and go back into windows. Make a copy of the undo.bin that is your usb flash drive and save it to your desktop. Better yet make two copies and save one online. Use a hex editor to open the undo.bin file you just created with hddhacker. It will look similar to the image bellow.
The serial number of the hard drive is highlighted. You can use the hex editor to change the serial number to whatever the original archos drive's serial number happens to be.
In the picture bellow I changed the WD serial number to a seagate. That was my original hard drive.
Red letters indicates change. If you still have characters left over from the original wd serial number you can use the space bar to clean it.
So the serial number is changed then just go ahead and save the modified undo.bin to the usb drive where hddhacker is located.
Go back and run hddhacker and this time select restore and follow the onscreen instructions. And the hard drive serial number is changed to match the original hard drive.
Ill add a how to for devices that use a sata drive. Its mostly similar though. If you have any questions please don't hesitate to ask. Ill post the bin files so you can save a lot of this work as soon as I can find them.
