Hi guys,

I want to partition my 64GB (I know, 59GB actually) microsd card into 2 x 32GB FAT32 partitions. I've tried to do it in windows, using MiniTool Partiton Wizard like I did with other microsd cards until now, but without success: the tool creates two partitions but the 2nd one is not usable (it does not have assigned a letter); any attempts to correct this were futile.

Can this issue be fixed somehow? If yes, how?

Start over, get it back to one unallocated partition, then use the Aparted app from play store.

Or you can try this

Thanks for your reply @Droidriven! :)

I've managed to create those partitions: sdcard1 and sdext2, both FAT32 and having 29.5GB each. First partition (sdcard1) is working flawless: access speed, read, write. The 2nd one...

The 2nd one (sdext2) has an issue - I cannot create files (.txt), in root or in other subfolders. However, I can access it, move data to it from the other partition or from the internal sdcard and I can create folders and subfolders. In android's settings->storage menu, my external sdcard is shown as it has only 29.5GB (out of 59GB) but nothing about partitions.

Is this a permission issue (platform.xml)? Can it be fixed?

I don't know what your issue is, maybe because one partition is the primary partition. Did you choose all the same options when you set the second partition?

What android version are you using? Lollipop and Marshmallow do have permission configurations that are a pain, especially concerning extsd permissions.

I'll see what I can find, can't promise I'll find you an answer though.

The partitions' settings are identical, with the sole exception that one has to be the primary one. The microsd is new and tested with a few software programs to be sure it's not a fake (it's not).

I'm using AOSP 5.1.1 and yes, I believe there is a L permission issue.

Don't worry a bit regarding this issue. :) If you or someone else will find the solution, it'll be great, if not, life goes on. :)

Thanks anyway for taking your time!
