I have a problem with my hard drive. I have tried everything. My SSD drive space keeps disappearing. I have turned off page file, hibernation, index and have everything on other drive. I freed it up to 16.3 gigs free. Left and came back and it has 13.8. I have ran disc cleanup...treemap and cc cleaner...Sometimes when I reboot 2 to 3 gigs reappear. What is going on here...Has anyone seen this issue?
