Problem in Exchange 2013 C: Drive

Dear All,

i'm facing issue in C: Drive which Exchange installed on it, till now, 160 GB is utilized for C Drive, although the total size for Drive contents with all hidden files is about 95 GB, which means we are missing 65 GB, so where is that spaces goes?

Exchange 2013 SP1 CU7 installed in Windows 2012 R2 fully updated up to today.


Kindly check the below:

Do you have Volume Shadow Copy enabled?

Could also be that Windows is reporting its free space incorrectly. Try running CHKDSK against the C: drive and see if that fixes it.

You could also check the IIS log files, antivirus definitions folder, temp folders, and exchange setup folders etc..

Make sure your full backups are 100% OK. The transaction logs exchange creates only get purged if a full backup is done and it has to be successful. The backup utility used also needs to be exchange aware.

If you don't do full backups, or your utility isn't exchange aware, turn on circular logging so that old logs automatically get cleared.

I would download TreeSize Free from here and then use it on the C: drive to see what's taking up the space as it automatically sorts the folders from largest to smallest in a nice GUI format. Remember to right click and Run as administrator when you run it as well.

@Gareth Gudger, Volume Shadow Copy is not enabled

@Zacharia Kurian, IIS log files, antivirus definitions folder, temp folders, and exchange setup folders ... are all calculated in the size which mentioned in the picture

@SatyaPathak, i did all of that before i post the question, i'm talk about 65GB which is not appear

@rindi, exchange DB and Logs in another volumes

@VB ITS, i use the tool, it's appear what i can see in the picture, it's good, but it didn't appear the missing 65GB

Can you run a CHKDSK against the C: drive to see if Windows is just not reporting the space correctly?

Is there only exchange on the server, or does it do something else too?

@ exchange, it's only Exchange 2013 server.

Yeah I'm with Gareth, run chkdsk /f /r c: in an elevated Command Prompt window (i.e. right click Command Prompt and Run as administrator) then check if this fixes your issue.

Hi,

Could you please try removing Recycle Bin directory with the following command to see if its clears any space?

rd /s c:\$Recycle.Bin
