windows 7 - Hard drive appears in my computer at startup but disappears after approx. an hour

If I leave my pc off for a day, come back to turn it on my HD appears in My Computer and is accessible. But some time later it starts to make a noise as if it's scanning and it disappears from My Computer.



I tried restarting, but that didn't change the outcome. My BIOS settings show that it's there, but nothing on startup or in Device Manager or Disk Management.




It's not my main drive, it's actually my media drive and it's only ever done this since I installed Windows 7 32-bit on my computer. I previously had Windows XP on it.



The hard drive is about 2.5 years old inside a 5 year old computer so I didn't think it was a HD failure so soon, but I don't know a whole lot about computers so it may be that.



The last time I had this problem was when I initially installed Windows 7 on it but I found somewhere online where it said to change the drive letter and it worked after that. I tried that again but it still disappears.
