Hi k3ro120, that message indicates that windows has detected the disk you're using is not reliable any more and is likely to fail in the near future. Actually it's not really Windows that's doing the detection, but for simplicity's sake let's say it is.
My suggestion would be to buy a new hard drive and back up to it as soon as possible.
If you're confident you can disassemble the drive from your laptop and replace it, then by all means buy an internal 2.5" drive and clone the existing one onto it, then switch them. Otherwise go to your nearest PC shop and tell them that you need to replace the hard drive and clone the existing one onto the new one.
Hope it helps!
