I have an interesting question. I have an exchange server that is on windows 2008 r2 and have 5 HD on it. C: windows files, E: that holds one of our Mailbox databases 87.9 GB with 28.8 Free, F: that holds 3 mailbox databases, 147GB with 43.9 Free, G: for Intronis(Thats our offsite data backup), H: Pagefile.
So if go into the E: Drive and add up whats in there and subtract it from the total I get a number that's not the same as whats free. So for this drive I showing that I'm using 52GB. But if I subtract that from the total on the drive I should have 35GB free? What does the drive not reflect this. This also happens on the other drive with the other databases. Also, what is interesting that during the day the size of the drives that show free slowly drop. The somewhat recover the next day but not as much as it went down. Would there be hidden files that I'm not aware of. I already have show hidden files and do not see anything. Does exchange hold onto space somehow? and how do you reclaim it?
