We have a dell small business server that has a 25gb primary partition on it. The disk is repeatedly saying it is full however when we go into the contents of the drive and select all>>properties it only shows 16gb of data on the drive. Basically we are missing 10Gb and the drive keeps filling up. Even when we erase things off of the drive it still just keeps filling up repeatedly. I suspected a virus but symantec endpoint protection was fully updated and i ran thorough scans and it picked up nothing. I also ran a rootkit scanner and it did not show anything either. I am quite dumbfounded and would appreciate the help.
