Hi ,
Our client has a server 2012 and on the E drive which is just a shares drive its showing on the properties of the Drive that it is using 145GB but when i do a  treesize it shows only 94 GB used.

I have not set up shadowcopy on this drive and there are no hidden files.

Any help would be aprreciated.

Regards

Matt

Have you had a look at System files/settings?

Page file, recycler ext?

Can you post screenshots of Disk management, E drive properties and treesize?

you must run treesize as an administrator to get accurate results

Probably or most likely, David is correct completely.

TreeSize may not be reporting data based on where it does not have permissions (this is not the same as a hidden or protected OS file).  The drive properties will report total disk utilization.

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

you can also run a chkdsk /f on the drive - it helps often

if you are admin, the remnant candidates are (might not be exhaustive)

- recycle bin (first most obvious and often forgotten possibility)

- system files : namely a huge pagefile.sys that may be located on the E drive, or possibly windows updates remnants (can't think of anything else that could take that much space). there is a specific setting in explorer (next to the hidden files) that will let you display system files. i'm unsure of treesize's behavior regarding system files when they are hidden in windows explorer.

- Alternate Data Streams. quite unlikely and would be the sigh of virus corruption or someone voluntarily messing with the system. i remember a rather old virus that would clutter a drive with ads until there was no disk space and that produces many strange crashes, because the system would think it had some space left while it did not. i'm unsure how the corresponding space is accounted currently but i'd assume it now shows in the total size but not in each file size.

- misnamed files : this can happen even involuntarily with some non MS clients when you store files with unsupported characters and/or charsets (UTF8 "\" for example). this will confuse software such as the explorer or treesize (which will quite often simply not display the file) but the files still take space. files that start with a dot can also do weird things in windows.

- failing filesystem. i deem this very unlikely given the size of the missing space and the fact it would most likely produce tons of alerts you would have noticed by now, but it is not 100% impossible.

btw, what is the overall size of the drive ?

if you found the remaining hidden 39GB (145-94+12 in the recycle bin) the answer may benefit others (including myself). thanks for sharing if possible. regards
