Hi guys,

Not really a discussion here.

I bought a 64GB SDXC Card and came across the following discussion...
https://forums.synthstrom.com/discussion/2151/deluge-sd-and-formatting

Short version of their issue:
Extending the storage size above 32GB (and format in FAT32).
FAT32 (required by Deluge) can handle up to 2TB.
But the Windows default tools reach their limitations, when it comes to sizes larger than 32GB.

I (...kind of) went the opposite way and wanted to share it:
Shrinking the volume of a 64GB SD card to 32GB.
At the moment no more storage is needed and it is easier to achieve with windows default tools.
May be this is a little help for some Windows-users.
An addition for Linux (manjaro-noob here) or MAC OS as completion would be welcomed. :)

The task you'll have to do:
You'll have to shrink the volume on your SD card, so it does not exceed a size of 32GB (32768).
Otherwise the Windows default tools can't format the volume to FAT32.

Finally, the steps:
1. Connect the SD Card to your computer.
2. Open a command line by using the search function within the start menu. Just type "cmd". [PRESS ENTER]
It will be presented to you.
4. Within the command line type "diskpart". [PRESS ENTER]
With this you'll startup the windows default partitioning-tool in another window.
6. Within diskpart, excecute the steps shown in the following:

  • list disk (lists all hard drives, plugged-in USB devices, etc.) [PRESS ENTER]
  • select disk x (where size refers to your SD card) [PRESS ENTER]
  • list Volume (presents volumes on the selected disk) [PRESS ENTER]
  • select Volume x (where size refers to your SD card) [PRESS ENTER]
  • shrink desired=32768 (32GB) [PRESS ENTER]
  • format fs=FAT32 quick [PRESS ENTER]

Roll back:
1. Connect the SD Card to your computer.
2. Open a command line by using the search function within the start menu. Just type "cmd". It will be presented to you.
3. Within the command line type "diskpart". [PRESS ENTER]
Startup the windows default partitioning-tool again.
6. Witin diskpart, excecute the steps shown in the following:

  • list disk (lists all hard drives, plugged-in USB devices, etc.) [PRESS ENTER]
  • select disk x (where size refers to your SD card) [PRESS ENTER]
  • clean [PRESS ENTER]
  • create partition primary [PRESS ENTER]
  • format fs=FAT32 quick OR format fs=NTFS quick [PRESS ENTER]

Cheers and Merry Christmas!

P.s.: If I dropped this at the wrong place, please let me know.

    I don't mean to diminish or nullify your amazing and caring effort. However, EXFAT should be used as the successor of FAT32 and it can handle bigger sizes without issues. I hope this helps
