Inflated file size on Seagate NAS 4bay device

I bought two Seagate NAS devices (4 drives at 2TB each).  It is setup using a SimplyRAID config (default) and has 6TB of usable storage space.  I have copied 200GB to it but it is reporting that all 6TB has been used.  I called Seagate and they told me that there could have been corruption when copying using Robocopy and to blow away the volume and recreate it which I did and this time, I just did a drag and drop from Windows and I get the same thing.  Firmware on the device is at the latest version.  

Anyone else experience this or know what the issue is?  Thanks in advance...

Was a backup program of some sort installed when you hooked your device up?  If so, it could well be assuming it is going to manage the space, and thus showing nothing free.

Check your documentation.  Check for newly installed programs.  If you don't want their functionality, remove them.

before copying anything to it - did it show as 6 TB in disk manager ?

There is no backup program...It's a NAS device so I gave it an IP address and then I mapped a drive to it from the server.  Then I just did a drag and drop to the mapped drive (NAS).  It doesn't show in disk manager since it's a mapped drive.  The UI for the NAS shows that it was 8TB and it has 6TB of usable storage...

What Windows version are you using? It may be that your Windows is just reporting the available size incorrectly, possibly a driver issue. Can you use another computer/laptop device to connect and determine the available space? The GUI of the device, is that showing the 200Gb in use?

The drive itself is telling me that there is a certain amount in use, not Windows.  When I look at the size of the folder in Windows (mapped drive to the NAS), it tells me it's only 80GB.  But when I look at the space on the GUI of the NAS, it says that 4.4TB is free of 5.9TB so 1.5TB is used (not true since it's only 80GB of data that was copied to the NAS.  See screenshot...

Screenshot looks OK to me. What is your Windows version and do you have another PC/notebook to test with?

Using Windows 2008 Server.  Screenshot looks good to me too...Except that I've only copied 60GB to it, not 1.5 TB.

Ok, a few simple questions:
(can't explain this sofar)

- is the source file from a compessed volume?
- if you delete the file from the NAS, what is the available storage?
- what is the file system on the NAS?
- what is the file system on the Windows 2008 server?
- can you show all shares that are created?
- what is stored on each share?

Seagate called me back and said that for each file copied, it will reserve 1MB of space on the NAS.  Unfortunately, I have hundreds of thousands of files in that 60GB so that is where the size inflation is coming from.  A file may be 30K that is being copied to the NAS but once it get's there, it takes up 1MB.  Not sure why but that's what they said.

If that's the case, I would suggest that you store that huge amount of files into an archive (zip) on the NAS. That way you keep the amount of storage that you now loose because of the 1Mb per file usage.

That's exactly what Seagate recommended :)
