Create VHD (virtual disk) from Windows on TC to avoid FAT32 issue.

To answer another thread,

I spent a bit of time messing around with fixing the FAT32 limitations from windows, by using the same trick Time Machine does, ie create a virtual disk on the TC and write to that instead.


This is not a question but would appreciate others giving it a try.


I have a newly installed Win10 on a computer to run this configuration.


Open the Computer Management /Disk Management.


Create a VHD on the TC drive. (My test device was a Gen4 2TB).


I used a size of 100GB and VHD rather than VHDX ..


It took sometime to create the file and it might need a reboot of the computer and open the network to connect to it.. you can then open disk management again.. I set it as GUID drive and formatted it NTFS.


I have it mounted now and can copy files larger than 4GB FAT32 limit to it.


No idea how well this will work long term.. but it might help someone else.


I am still checking if the TC disk will spin down even with the virtual disk open.

How about the following:

  • Open Windows text editor.
  • Enter: net use <drive letter>: \\<servername>\<sharename> /persistent:yes

    Substitute the mapped drive letter for <drive letter> above.

  • File > Save As
  • Save as Type: All Files
  • Name it something like: mapdrive.bat
  • Add batch file to: C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup


Have not tried it after PC hibernation, so I may have to do some more digging.
