You did used a paper clip on the reset hole did you not of the player?
If you are lucky it is not the hard drive that went bad but some other part of your player and if so it might be a good idea to buy a second hand player of the type on ebay and change out the drives. Doing a fast look on ebay you should be able to pick a working used one up for 60 dollars or so.
You could removed the drive and look at it using a USB to hard drive adopted however I have a feeling that you are going to be looking at a database that contain your music that you will not be able to deal with directly and an adopted will set you back almost the same as just buying a used player.
Second in the future back up your important information including you music library! An external USB hard drive of 500 G is around 80 dollars!
