How to fix the Save to Disk Feature on Laptops

Hey everyone, Ive read that the Save to Disk feature is pretty important for your laptops data. Currently when its on the save to disk mode this error comes up:

"Save to Disk partition not found
Save to Disk feature is disabled
Run Phdisk for information.
File: creat new. PARTITION: consult manual.
Hit any key to exit."

and the computer will boot normally and work fine. I was wondering how i can fix this without losing my information on my hard drive? All your help is very much appreciated. Thanks
