Thunder7 recently told me that he bought an used Xbox gaming system and discovered that the hard drive was full of music files from the previous owner. The original Xbox uses an internal 10 gigabyte hard drive to store save games, patches, music and images. The new Xbox 360 and Sony's PS3 will also utilize a hard drive and the following tip is also valid for them.
If you do not delete the personal files on the hard drive before you sell the system the new owner will be able to watch, hear and view them just like you did. What Microsoft did not tell you is that it is possible to recover the files even though they have been deleted by connecting the hard drive of the Xbox to a computer system. File Recovery tools work on Xbox hard drives just as well as they work on your PC.
Besides files, it may also be possible to recover account information.
The new owner of your system could run data recovery software by connecting the hard drive of the Xbox to a computer.This way it may be possible to recover files that you have deleted prior to selling your old system to the new owner. The same holds true of course for every other sort of storage device that you are going to sell. It is possible to recover files even though you deleted them.Basically, as long as it has permanent storage, it may be possible to recover files from it even if you delete the files prior to giving the system away or selling it.
The only secure way that I know that would delete the files safely would be to connect the hard drive to your PC and use a tool like eraser to erase the personal files on it.
You need to unlock the hard drive of the Xbox before you can access the Xbox hard drive in windows.
It is also a good idea to remove account data from the system before you are selling it, this can be done using the Xbox configuration screens so that you do not have to use third party tools for that.
