Hello everyone!
Something strange just happened.I have about 66GB left out of 120GB and i got this warning message.I checked my computer and i saw that there were about 10KB left!In a couple of seconds,it went up again to 66GB.
Why did that happen?I don't have any problems so far,though i am really worried after this.I scanned the disk with an AV program,nothing was found.
Any opinions?Do i have to worry?
Btw i am running Windows 7 64bit.

I just checked Samsung Magician and the date and time of last performance optimization was around the time i got the warning.I guess that was it?
