The hard drive nevr stops spinning until I eject it. What I mean by working, is that it makes the usual HD noise as thought it is being used by some program. For instance, if you copy a large file to an external HD, it will make the usual HD noise as it writes to the disk. This is the noise I am talking about. I don't know what is causing it to make this noise, because It will do this even when my computer is Idle. It also does it when i play my iTunes, and can interupt a song that I am playing because the drive is being accessed.
If i can give any more information, please let me know. I hope this isn't a serious problem with my drive.
