Difference in available storage space between WebGUI and Finder(AFP)

Running 6.5

A couple of weeks ago I removed a "private time machine" allocating roughly 500Gb. The avaialabe storage in the WebGUI differs about 500Gb compared to what I can see in Finder, mounting a AFP-share.

 

Any idéas?

    The NAS uses base 2 (like most PCs) whereas the Mac uses base 10. So you will get a larger number on your Mac but the amount of free storage is the same.

    Also the Time Machine tab won't let you set a quota that is as large as all of the remaining space (it's not advisable to completely fill a volume).

    What numbers do each report? And how much space is on the volume?

        I´m doing a huge sorting of my data, all across my computers, external drives and the NAS. 

        This problem came when i removed a private time machine and I´ll soon be doing it again. 

        Can I fix this some way and how do I remove private time machine the right way so this does not happen again?

  • So it's just a coincidence that the size of my deleted time machine matches with base 2 vs base 10?
    Even though I never seen any difference in available space before?

      Base 2 to Base 10 conversion would be e.g. 

       

      1GiB (base 10) = 1024 ^ 3 / 1000 ^ 3 GB (base 2)


      Disk manufacturers and Macs use base 10 whereas most PCs use base 2. PCs tend to call GiB, GB.

        That´s not the case for me. Using your formula and to my current numbers:

         

        NAS Webgui 2,95TB equals 3,021TB. Finder shows 3,24TB. 

         

         

        EDIT: I stand corrected! I was wrong, mdgm was right!
