[Q] List of ROMS that support micro sdhc cards?

I'm a regular user of XDA roms for flashing, but I ran into a problem that I think should be included in every rom listing, which is the type of micro SD card supported by that particular rom. I flashed a rom a few months back that, I thought at the time, had made my Sandisk 64gb microsdhc card unuseable. The Samsung Galaxy S3 has native support for these cards and the exFat file system. I ended up recovering my data on a PC, but I sent 2 cards back to Sandisk thinking they were somehow corrupt. I eventually switched to Scott's Roms which recognized the cards just fine. My humble advice is for developers to please state which types of microsd cards are supported so that others avoid this problem thinking that their sdcards are bad. Thanks .

Why not just format it to fat32? That's what I did to mine. Also cwm does not support exfat (I found out the hard way)

This is not a ROM issue this is a Samsung issue. If you search for microsd error or microsd no longer working you will find people having this issue. The consensus I got from researching is that it has to do with how Samsung handles exFAT and that you should go with FAT32 over exFAT. I had a microSD UHS-1 Class 10 card just stop working and didn't work anywhere and I was using CleanROM.

Cards using the exFAT file system cannot be read by open-source ROMs like Cyanogenmod because Microsoft owns the exFAT file system and in order to support it, Microsoft would have to be paid a licensing fee. Touchwiz-based ROMs can read them because the support is baked into Samsung's software.
If you want your card to work with all ROMs, you have to format it with the FAT32 file system. Additionally, not all formatting utilities seem to do it right for SDXC cards. I used the GUIFORMAT program detailed in this thread: http://forum.xda-developers.com/showthread.php?t=1773735. Unfortunately this means that you won't be able to store files larger than 4GB on your SD card.

That was my understanding of the Touchwiz roms, but I just installed Galaxy MOD RLS11 and it is giving me that error "SD card safe to remove". I know there are some utilities that will format cards above the 32gb limit, but the 4gb file size is a pain for some of the movies,etc. I get with Adownloader. I have the 32gb S3 and the 64gb Ashcroft which makes me want to never own a Nexus device . No issues on Scott's rom, but it isn't as fast and it doesn't have the 4.2 camera or gallery, which I really like.

Kernel has to support ExFat also so if using stock kernel and modules are still in rom should work.

[Disussion] Micro SD Cards SGS4 I9505 64 Gb

Recently went from SGS3 to i9505 as Samsung has left us not much space on the 16gb version I purchased a Samsung 64Gb class 10 SDHC card .... Welcome to my nightmare. ...
1. Could not restore via CWM recovery I would always get MD5 mismatch
2. Take a photo it would just dissappear after a couple of hours
3. Folder mount or LinktoSd would not work correctly
4. Media files would not play correctly become corrupt
The CWM not restoring was the worst its kinda like playing Russian Roulette .. So I dusted my 32 Gb card off cleaned it up .....No more problems.
I've noticed alot of people seemed to face the same issues with 64Gb cards . So I thought I would start this thread to see if we can find the common denominator with this issue
Please post your experiences with SD cards here. Should I just write that one off to experience and go buy another 64gb card ??
Which format is best SDHC or SDXC
Should we format exfat ext4 or fat32
Please post any information regarding SD Cards and what dramas you have had

Micro SD on GT-I9505
GALAXY S4
Hello, i just have got a Samsung Class10 not (UHS1) micro SD Card 64GB. And i put it on my Galaxy S4.
All was ok, until I passed some archives from the Internal memory to SD and Recorded some videos, then it appeared a message Saying "Empty Memory Card or Incorrect File Format" and tells me to Format it. Even it says I need to Format when i connected the Micro SD on PC (I connect it Through a Printer SD port with SD Adapter).
Now Im afraid I will lose my recordings and files.
So Should i have Formated it before giving a use?
Well the other detail is that after formatting it, looks like it cant be readed, my printer gets stuck saying Loading Photos.*
So it isn't readable on PC after formatting it on my android device?
Then I tested it on my Canon camera and it reads.
Looks like its defective. Many files got corrupted or simply dissapeared. And if I try to read via card reader on pc it says that doesnt have format and ask me to format it. Anyways it cant be formatted, an error appears.
what should i do with this card?

Marshmallow SD Card Issues

Hey guys,
I was hoping someone with some experience with Android M could help. After installing the OTA update and upgrading to Marshmallow, it seems that the OS makes you format microSD cards as either portable or internal storage. The issue that I'm running into is that after formatting the memory card as portable storage, the system formats it as Fat32 so I can no longer transfer large MKV files to play in Kodi. Prior to installing the 6.0 OTA, I had no issues transferring the files to my microSD card.
As a workaround, I tried using my USB OTG drive to play the videos but I can't get Kodi to recognize the drive as a source for my video files. Does anyone have any suggestions on how to get around these new memory card complications that Android 6.0 has introduced?
I would greatly appreciate some help on this as this was one of the main reasons I purchased this tablet so that I could use it as a temporary HTPC when I'm traveling. Thanks in advance!

Have you tried removing the SD CARD and formatting on a PC?

Seems that Marshmallow's not all it's cracked up to be.

Don't have marshmallow, but have you tried reformatting the SD card on your PC using exFat or NTFS instead?
I don't know if marshmallow will prompt you to reformat again when you put the card back in the Shield though...

You didn't mention what size of card, but if it is larger than 32gigs you will need to put the sd card in a computer and format as NTFS. Android doesn't support exfat, only fat32 and NTFS. Try that and let us know what happens!

Oh, wow! Your personal experience with two different phones made by two different manufacturers running an old system that was never designed for what Marshmallow does obviously contradicts and demolishes what I said.
(/sarcasm)
ExFat support can be added to android kernels, if the manufacturer decides to do so. Samsung, a maker of sd cards ranging from 4gigs to 200+gigs, has an interest in making sure that their devices work with their cards that also work in a variety of consumer computers. ExFat support can also be added in customer kernels, should the maintainer decided to do so (in fact, many kernels that I see for modern devices that also support an external sd cards proudly show that they support ExFat).
Android AOSP, without any mods or other built in support, does not support ExFat well, if at all. It may or may not work. The fact that nVidia has written that any cards over 32gig must be formatted to NTFS tells me that they have not chosen to build in ExFat support into their devices. Should someone desire to flash a different rom or custom kernel that support ExFat, that is their business. But since the OP didn't list what size of card they used, or if they were using any mods or a different kernel, I had to go with the most basic support.

ST8 = Shield Tablet 8" (original vs. K1 model).
Point is, this goes against your open ended and incorrect "Android doesn't support exfat, only fat32 and NTFS" statement.
Supporting exFAT in Android makes sense as it's the recommended file system by the SDCard association for SDCards larger than 32GB.
NTFS is in the same boat - it's also not officially supported by all Android implementations.
Marshmallow formats SDCards to Ext4 (and encrypts) when configured as internal storage. When configured as portable both exFAT and NTFS (and Fat16/32) may all be an option - OP can try both if using the portable option.

Similar problem with lg g2 on marshmallow
Hi,
Having a related problem with kodi on my phone.
On lollipop, kodi found my 16gb Fat32 otg USB drive as a source, but won't show up now I'm on marshmallow. I can still play video through mx player, fx explorer media viewer, and os video player. I searched around storage and mount folders, but can find no access to the external drive browsing the file system unless I'm using the native file browser.

Marshmallow detects partition very different with Lollipop. on Marshmallow your device can use sdcard with 128 GB like internal
its mean sdcard needed change partition format to another type (not FAT, NTFS or exFAT) the matter here then you plug that sdcard to windows, windows wont detect your sdcard but you can see it through another program like MiniTool Partition Wizard.
The problem with marshmallow and this partition used to drop out connect with your sdcard. only one way to fix it reboot your device. also, sometime they cant turn wifi on then you just needed to reboot again to let your device working normally.
We needed to wait for a new patch.

Adopting internal storage results in corrupt storage

I have recently got a Shield Tablet and I have attempted to add a 128GB to the internal storage but every time I go through the adoption process to bring it into internal, it formats it and results in it being corrupted? The sdcard is brand new.
Tablet is on Marshmallow.

I am having the same issue with the Shield tablet and a 128g sd card. I can use as portable, but trying to adopt as internal storage always returns the "damaged" partition after formatting and starting the moving process. I have tried formatting as ext4 in a PC first as recommended by others to no avail. If anyone is able to get this working please post your fix.

Found the below "Notes" on Nvidia's site. Looks like you'll have to format NTFS on your PC. Some PCs will not allow you that option out of the box, but you can easily change Windows' built-in formatter's options to allow it to format NTFS. The settings are somewhat hidden. To enable it, open up Device Manager and find your micro-SD card, go to the Properties -> Policies tab and then choose "Optimize for performance". Once you've done this, you'll see the NTFS option in the format dialog. Just make sure you "Eject" the card properly, as it seems it's more easily corrupted if not ejected properly.
NOTES:
The ability to move data to SD card is variable for select*apps*and games. Onlyapps*that developers have opted in as moveable to external storage can be moved.
The SHIELD tablet K1 only supports writing to FAT32 and NTFS formatted cards.
64*GB*(or higher) microSD cards – Android does not support the exFAT file system out-of-the-box. Because the standard FAT32 file system does NOT support partitions greater than 32*GB*by default, 64*GB*cards come pre-formatted as exFAT. If you want to use a 64*GB*microSD with the SHIELD tablet K1, it has to be converted to a file system format that is supported by stock Android, which in this case is NTFS. This can be done using a PC.
Android KitKat significantly changes the way applications are allowed to use SD cards. If you use SD Card to store data, please read here for further details."

Hey, I have a similar problem but wanted some opinions.
Received my new K1 and updated to MM and everything is cool. Installed PNY 64GB (10 class) and chose the integrated storage option. The K1 sees the storage and I'm able to move apps to it. My problem is that new apps cannot download due to no storage. The message "whatever app cannot be downloaded. Install a SD CARD......something, something" (sorry, I'm at work).
Will formatting my sd card to FAT32 or NTFS fix this or is there something else wrong? I haven't seen any messages or errors regarding corruption and the sd card is working.
Thanks for any helpful suggestions!

When my 64Gb card was formatted exFat as it came stock, i had the same issue. I'm on LP. I had an almost empty card inserted, other than some mp3 files, and kept getting the message that my storage was full and that i need to delete some apps. I've since formatted it NTFS but i have not checked to see if items are being sent to the external SD. Don't have my tablet with me right now to check, but i wanted to reply to you that you were not alone in seeing the out of room message.

I had my PNY 64GB formatted with exFAT and it worked ok. I've switched to adopted storage and that worked too. But I saw other glitches with internal storage, such as MTP not seeing all files/folders even after reboot. I think "adopted storage" is buggy in general currently. It's also quite slow. Not impressed.
I prefer the Move to SD of Lollipop and Kitkat.

Do we already have a fix/workaround for this? I have a K1 (with the latest OTA 1.2) and 64GV Samsung Evo, formatting the sd card as adoptive storage still says corrupted. I already tried formatting it as Fat32/NTFS but to no avail.

I also couldn't get adopted storage to work.
The best fix for me is not using adopted storage
Instead I use an app called FolderMount which simply creates a symbolic link (is this the correcton term?) on the device's internal storage for whatever folder/file you like. It integrates moving data and managing it as well making the process as easy as it gets though you can of course do the same thing manually as it's using linux operations to do these things.
After you make the symbolic link when apps look for the data in the usual place on internal storage they "see" it but the data is actually whereever the symbolic link points to ie. on your external SD card.

Not found any real workaround for this it makes the tablet a bit of a dud

Caveats: I actually haven't tried it on Marshmallow since I went back to LP however I cannot see any reason that FolderMount will not work as it's using underlying Linux operations to do all the work. But YMMV.
I like this approach since you can move any folder from internal storage to microSD which makes it very flexible. For example you could move:
/Download
/Images/DCIM
/Android/obb
/Android/data
/where you store recorded videos/
and never worry about internal storage again (until you run out of microSD of course lel)
Or whatever you wanted.

There's a problem with cards 64GB and up. I managed to format as internal storage a 32GB one, had no succes with 64 and 128 ones

I couldn't get portable storage to work on the stock MM RoW LTE rom. It works perfectly fine on all the custom roms I've tried (Bliss, Temasek, RR, etc) but none of those have LTE so for me it's either or if I want to use a MM rom. Otherwise, I'd have to use a LP rom for both to work...

I've hit this issue using the RR rom with my 128gb SD. But then if I keep the card in portable mode, I have those permission issues with my emulators. Has anyone got any suggestions or recommendations?
I've so far tried xInternalSD, SDFix and FolderMount with no success and I don't want to do that solution where I have to adjust the permission xml of all my apps. Its micromanagement I don't want.

I just have to use fat32 to get my 128gb card to work.

To work as adopted storage or portable storage? Because mine is working in portable mode, just has write to SD permissions issues for any apps not updated to deal with MM's new OTT security requirements on External SD's (which is most apps to be honest).

Adopted storage, I only tried it once but didn't like it so using portable.

Being Fat32 initially shouldn't have made a difference, because the card is reformatted to ext4 when its made into adopted storage and the tablet just seems incapable of reading an ext4 encrypted SD Card, so it comes up as corrupted.
What brand and model is your 128gb micro sd? And was it the stock rom you did it on? I'm using a Sandisk Ultra myself, and this definately does not work.

It's been awhile so I don't recall all the things I've tried nor the roms. All I know is I got it to it to work once. Think I have a SanDisk something. Just wasn't worth it in the end to me. If you're trying to get it to work, doesn't hurt to try. Stranger things have worked to fix issues in android.

Help with external SD card

So i have had the P900 for a few years now and want to try and get some use out of it. Im into photography and would like to use the tab for some light editing while on the road. My question is, will the tab be able to read a Sandisk 64gb Extreme pro SD card if i get an OTG? I am running and old version of Android, 4.4..2. I believe its original firmware only thing that was done was root. Thanks

First of all you should update to stock 5.0.2.
I'm having a 200GB card internally but if your OTG is good enough it should be able to read it of course depending on the file system it uses.
Why don't you want to insert it?
Btw my P900 is working with Lineage OS 14.1 = Nougat perfectly well.

Went ahead and updated to stock 5.0.2. Got scared there for a minute as i had done a mistake trying to flash a custom rom and took mea while to find stock rom. Now in regards to the external SD card, I use it on a Fujifilm mirrorless camera and my understanding is that the SDXC cards use the exFat format. I want to make sure, before i buy a OTG cable, that the tab can actually read the card. I want to be able to transfer pictures from said external SD card into the tab and edit them with Lightroom or Snapseed.
I also have another tab, the Samsung Galaxy 7.7 tab, and that one doesn’t read the SD card, i get an error message when i connected the sd card on its OTG. Something about “high power device” or something similar.

Afaik you can format cards like you need it.
Of course with the appropriate formater.
FAT, exFAT, NTFS, ext2, ext4.... depends on your necessities.
My P900 card was formatted exFAT and can read/write.
In other devices I use other formats (SDHX as well).

I believe I read somewhere that someone connected a 1TB portable HDD. I'll try to find it...
