I have this 1Tb external drive that says it only hase 115G left, and I went through all my stuff on the drive and I only have 620G on it. The actual amount of space on the drive total is 930G, but this still doesn't add up. Anyone know what could be taking up extra room, or suggestions on what to do? Edit: Running check disk right now to see if it can find any corrupted sectors or file errors that are large enough to almost take up 200G Edit: It's done running, it said that it found some corrupted files and fixed them, but it didn't free up any room on the drive. Now running Disk Defrag Edit: No fragmentation found, Avira finds no virus' on the drive.
