Just joined this site and I am not 100% sure if this is the correct format, but this is what I have. I have DFS setup on two servers. One is 2003 and the other is 2003 R2. I am not sure if that is important or not, but it is why I need to figure out what is going on here. The FRS staging folder is on another drive. I used TreeSize and determined that there is 30 GB of data on the 75 GB drive in question. Windows shows 9 GB free. I have looked through several different posts, but none seem to answer this part of the issue. The used space in explorer shows 66.5 GB. I can double click on the D: drive and right click on the two folders there, do the math and it adds to 30 GB (thereabout). Any ideas what could be accounting for the missing HD space? I have checked for fragmentation and run an error-check. The drive manager shows it as a healthy drive, but I need that missing space.
