Two Drives

Im not sure of the best way to explaine this, so bare with me here. Lately (3-4 months) I have been getting pop-up error messages saying that my memory is to to low. So I clean Temp files, Recycle bin... all that good stuff and its fine again, but not for long. I went and clicked on My Computer to see if I could figure whats going on.. when I saw.... HP_PAVILION C: which is correct, then I saw Local Disk F:. Seems this local Disk F: is backing up everything as well as running. So everything I do is on there. Its a small drive Total Size: 4.39GB Free Space: 305MB. My C: drive is Total Space:32.8GB Free Space: 22.8GB. Looks like im not touching that one...
I have tried running a System Restore (or Recovery.. get mixed up) and all it does is back everything up yet again... piles and piles of backed up stuff. I want a totally new cleaned out Hard Drive.. or to figure what this F: drive is.

Thanks for all your help!

open task manager and try and determine the program that is doing the backup operations. If possible I would get rid of this program as you can do backups yourself.
