Just joined so that I could reply to this thread. Thank you for posting all the information! I totally freaked last night when the 300GB drive I had placed in an external drive fell off the top of my PC (dont know how this happened as I wasnt even in the room) and it started playing its tune. Fortunately I didnt lose any data as I was ghosting my C drive to it as I was going to swap them out. Luckily this happened now rather than later (assuming that it might have occured on its own in time to come).
I couldnt get mine to boot up again after it died even though I did try knocking it a few times. Occassionally the sound would stop but the drive still wouldnt appear.
Just to be safe, I am replacing it with a Western Digital 300GB. Anyway, a big thanks once again. Having the mp3 to verify the sound was excellent.
