I have a couple old MP3 players kicking around and have always wanted to try this. A lot of MP3 players are just USB flash drives with the brains to play music from the files stored on them.
You can open the MP3 player up in Windows Explorer and music files are usually stored in the root of the device or in a folder called “Music”. Simply adding songs or removing them manually is usually easier than trying to do it in Media Player or iTunes.
So, what I did is take one of these:
Copied all the information that was on the MP3 player to a backup folder on my PC (in case things went bad). Downloaded Ubuntu 11, and it’s USB installer and loaded Ubuntu onto it:
I then rebooted my PC, selected “boot from USB drive” from the Boot menu and got this:
Finally I copied the music files back to the MP3 player, ejected it from the PC, plugged my headphones in and it played music like a champ. Now, I have an MP3 player and a bootable USB drive.
I was thinking of installing Backtrack 5 on it and making it into a inconspicuous looking penetration testing platform, but the MP3 player just did not have enough free space.
Pretty cool, just a note of caution though, this may not work on every mp3 player. Only try it on one that you can risk ruining.
