Why won't my SM-T320 read my micro SD card? - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

I'm running a custom MM ROM on my SM-T320. Everything is smooth and stable except when I insert a micro SD card. I know the pros and cons of "format for internal storage". That's not my issue. I know that you can have the T320 reformat a micro SD card to make it readable external storage. That's not my issue either. I can't figure out why, when I insert a working micro SD card with readable music and video files on it, the music and video apps on my device can't see those files. I know that the DEVICE sees the files. When I pull down the notice in the system tab about whether to "format or explore", if I select Explore, the utility sees every file on the drive and can play every one perfectly. So, why won't my media apps see those files?
If all I wanted to do was to plug that micro SD card in the T320 and leave it there for storage I'd have the device reformat it and be done with it. That's not what I want. Before this, I could have different micro SD cards with different selections of media and other files and plug those cards into whatever device I wanted to use to read the files. All of the devices would recognize and read all the micro SD cards. With Marshmallow that seems no longer to be true. Am I doing something wrong or is there a work-around?

That's a known limitation of CM13 for mondrianwifi. We have to wait until the maintainer submits this fix to the build.

64 gb micro sd problem(s)

Hello,
I just got a 64 gb micro sd and just been experiencing issues since. I have formatted it to Fat32. It would randomly not show up when I plug in my phone, it does not show under it.
When I transfer music...they break? Will say something like so and so cannot be played, format is not supported or file does not exist. When I look at my musics on the computer, i cannot delete because it says i need written permission.
I am at lost for word at the moment because it is the second one I got...all having the same issue. When I format to exFat it does not even get mounted.
Backup your SD Card to your PC. Use the phone to Format, then put all your files back onto the Card.
I have already done that, it doesn't work...wouldn't mount

[Q] How to Force the M8 to use USB Mass Storage, not MTP?

Hey everyone,
I know we all have our opinions on MTP, some like and some others don't.
As a Windows and Mac user, I think it is horribly implemented on our HTC One M8s. Large MKV and Flac files do not copy correctly (completely) to my phone's external micro sd card that is formatted with exFAT, and it's terribly slow. The problem also occurs with normal micro sd cards.
Is there any way to use a mod/application or system setting that removes all aspects of HTC Sync and allows me to mount my external SD card as just normal USB storage? I have 64 GB on my micro SD Card but cannot use it because I cannot copy over large files correctly because of this issue, and it's extremely frustrating.
Does anyone have any ideas?

Unfortunately, that's not really a solution. Android File Transfer is just an app that provides a connection between the phone and the computer. Additionally, it cannot transfer files over 4GB in size, which is absolutely ridiculous. I want a way to directly mount my SD card on the computer, so it is seen directly as an SD card in Finder. I don't care about accessing the internal memory.
What is the point of having an external SD card slot if you can't really use it properly? I'd rather not have to boot into windows to make this work.

And unfortunately, that is the only way wired to OSX ... Google changed the way storage is accessed (around ICS I believe) ... so MTP is the only protocol available ... even in Windows, the drives connect via MTP and not like a USB drive .... Try doing multiple actions like copy/paste simultaneously on Windows and you wont be able to

Remove SD card from phone. Put SD card into USB SD card reader plugged into PC. Profit.

Look, that makes sense, but it's ridiculous I need to buy a peripheral to use the external SD card on my phone. USB devices have been able to easily and quickly interface with computers since the 90s, it's absurd that I have to do that in order to do what I want.
And how reliable is that tray? How long before it doesn't go in properly because I have taken it out and put it in so many times?
I'm in the same boat. I use OSX as my primary OS and I'm just having to use AirDroid to transfer over files for now.
In http://forum.xda-developers.com/showthread.php?p=54035979 I may provide a partial solution; depending on your exact need. Look for the post I sent a few minutes ago. More to come in the next days; I will test other apps, and report.

SD card bugged after upgrading to marshmallow

Hi, I recently upgraded to CM13 (Marshmallow) to have a look at the new features. One of those was the new SD card management. I decided to format my sd card and make it part of the internal memory but something went wrong and i ended up with a 15mb sd card (instead of it's original 16GB) that I can't reformat in any way. I downgraded back to lollipop hoping I could format the SD there and recover my lost memory space but I can't manage to do it. I tried with many root apps on play store for that purpouse but none of them worked. I think it's maybe because marshmallow encripts the sd card before formatting it but I dont know how to remove that encription.
Anyone has any idea of what can I do to solve this? Thanks.
Make a format on PC. You'll lost your data whatever, but I think it may help ? but the best way for you is to flash another rom. I think.
You have to recreate the partitions on your SD. If you have a USB adapter, you can just do it in your PC (via right click on Computer, Manage and Disk Management or fdisk in linux). If you don't have a USB adapter, you can try to recreate via TWRP (I never tested this).
Delete all partitions and create just one VFAT/NTFS/exFAT
The problem is that I dont have a usb adapter or card reader and if i plug it via phone it doesnt detect it as mass storage so i can't format from there.
Go ahead and buy a USB Card Reader they are super cheap and handy.

SD Cards with Filesystem other than FAT32

Hey,
has anyone had any success with using SD cards formatted with something other than FAT32 on the Redmi Note 8 Pro? The 4GB file size limit and limits on usable characters in file names (although there might be easy workarounds for that one, haven't tried yet) make FAT32 a really poor choice for me. I have tried formatting the card with exFAT, NTFS, as well as ext2/3/4, but it recognized none of them. I get that Xiaomi haven't licensed exFAT or NTFS, but I don't see why ext2/3/4 wouldn't work. Probably just disabled in the stock kernel?
There's also this option to use the SD card as an extension to the internal storage. Not sure what filesystem that uses, but it doesn't seem like a very transparent and portable thing to do.
My device is rooted, so I'd be interested in root-only options as well. It's probably possible to get it working with external apps that include FUSE drivers (I have exFAT working using EDS on another device), but I'd prefer a "native" solution.
Thanks!

When I cannot answer your other questions ATM, I can already answer that one since I tried it with other devices and this one is no exception.
As you suspected, that's definitely is not a portable solution. You can no longer use the SD card as a plug and play portable solution.
That said it does not sound like a very good idea to keep ejecting that SD tray to transfer files, that would be done more easily with either an hybrid USB-C USB-A pendrive or just an OTG USB-C cable.
However that's always good to have an SD card in there to backup important files with a few thumbs presses at any time.
Speaking of USB-C drives/OTG cables, it is possible those do not have the same limitations SD card might have when inserted internally. I have not looked into it just yet because I usually do not put files that big on my phone, but I can see it could be a problem (large video files or backups for example).
Hope this helps (a bit).
Regards.
PS: As root have you tried to manually mount those drives formated as ext{2|3|4} from a terminal?
Try this, -
Connect SD card to PC.
Do back up of important files from SD card.
Open 'Disk Management' in Windows.
In 'Disk Management' delete all partitions on SD card.
Leave SD card unformated.
Download software 'SD Card Formatter'
Format SD card with this software.
Test SD card on Redmi Note 8 Pro.

SD card issues on reboot

I bought a G7 Play during Thanksgiving sales at Wal-Mart. It's been running fine until today, when I rebooted.
It's stock. I haven't unlocked the bootloader or rooted it.
I have a 64 GB PNY Elite SD card configured to be portable storage.
Today, when I rebooted, I got a notification "SD card issue. Tap to fix." When I tapped, it wanted to know whether I wanted to use the SD card as adoptable or portable storage, and wanted me to reformat the card regardless of which option I chose.
I turned the phone off and removed the SD card, replacing it with a 2 GB Samsung card. That one functions as expected.
Has anyone else seen this behavior, and is there anything to be done to fix it, or should I just contact Lenovo?
Thanks!
Try using another phone with this SD Card. If it works then your phone is having incompatibility with the card. Didn't work? Your SD Card data has probably got corrupted. If you can plug it on computer with an adapter check if it shows RAW in disk management. If it does try formatting with windows usual format procedure. If that shows an error your last resort would be using diskpart. use list disk, then select the disk which is your sd card, then type clean, then create partition primary, then format. That didn't work too? Then it's a hardware issue and what you got there is part of e-waste now.
