The size of the drive and whether ot not a third party partioning program was used might be the source of your problem. Partioning software such as Western Digital's EZ Drive move the boot sector from sector one to sector two. A boot sector virus will move sector one to another location that it can access and write itself to sector one. Also note that fdisk does not remove partion information but modifies it after a disk has been fdisked once. I didn't look up your model number, but if this is a laptop, you might have to have the manufacturers support to restore it. If it is a PC, you can probably run a debug script to remove any partion information stored on it and then fdisk/format normally. You have most likely already lost any drivers for your audio/video/etc so will need to locate them on the internet. If you want to try a debug script I will post one. DISCLAIMER: It is not advisable to run a debug script on a laptop. For most PC's it is OK, but you do so at your own risk.
