i have tried several roms, sd fix apps, and have modified the platform.xml manually and gave permissions to the mnt folder.
Nothing lets me write to my 64gb card anymore.
I've tried formatting the card via phone and pc disk management and several format exFAT utilities.
Nothing works.
Is my sd card screwed?

Go in to system etc then platform and make sure it looks like this
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>
yeah, i've done that. ever since i moved to a kitkat rom 6 months ago, i've only been able to read from it. Even when plugged into a sd card adapter in PC.
I don't know how my sd card got corrupt.
Sandisk brand?
yeah, is that bad?
I had that same issue and it is a simple fix, at least for me. I was embarrassed to know what it was. Anyways. On the SD card adapter you use to insert into the PC is a lock slide knob like mechanism. If you locked it then you will have your issues. Put it back in that adapter and slide it the other way. At least it worked for me after weeks of research.

If you try to format and it says successful but all your original files are still there, there's a good chance the card is corrupt. This happened to me recently. I was still able to read the files so I backed the card up and had it replaced through SanDisk warranty.
This tool saved my life on a 32 GB Card - not sure if it's relevant to the OP, but anything is worth a try after a certain point, you know? lol. The low level format using this tool took around 11 hours, significantly longer than the built-in windows format... it was an overnighter. I went from the card un-mounting anytime I tried to copy a file over (While I had borked my ROM and was trying to copy a new rom over to flash, of course!), to having no issues whatsoever. I really thought I was going to have to buy a new card but... HP Format tool to the rescue!

So why is it that every android I have does this to my apps? Randomly they get "uninstalled" meaning the apps just don't work and don't show up and it says they're on my sd card but it won't let me move it back or forth. Also I have a class 10 16GB micro as card. Jmzonev Rom btw. Thanks guys

Happens to me toooo..... Just dont move them on sd card.... Let them on fone memory.... They will be f9.... Also, go to manage apps and open the app... Force stop it and reboot... It will be back with no data loss and move it to phone.... Dont kno the reason why this happens... Maybe, someone would be able to tell...

unmount your external storage from setting for a while, then remount it again...

Do you use Sandisk or anther sd card?

I've had this, sort of behaviour happen before, but it was because the flash memory was corrupting. You may have a bad SD card, it does happen. I push many of my apps to my SD card, so I can tell very quickly if the card is at fault.
You should back up your SD card, and reformat it in FAT32, as the filesystem itself may be malformed.
I've also heard that PNY has fallen lately in their quality, so you may want to try another SD card, if the above doesn't work.
My app of choice for keeping apps on my SD card is Link2SD: https://play.google.com/store/apps/...=W251bGwsMSwxLDEwOSwiY29tLmJ1YWsuTGluazJTRCJd

Ive had my tab 3 sprint model since day one and never had any issues. I recently got the ota for 4.4.2 KitKat and now my SD card has mad issues.
I've always used a 64gb micro SD card without any issues.
Now, after updating, I'm unable to copy or move media (docs, music, pics, videos or anything else for that matter) to and from my SD card. It reads as app storage only and I'm able to send apps to SD via applications menu and thru titanium back up as well.
I'm fine with app only storage as I have a premium Dropbox account and unlimited data from T-Mobile.
The real problem is - anytime my tablet sleeps or the screen locks, my SD card vanishes. Its not mounted anymore nor did I get a toast saying its has Ben unmounted.
After taking out the SD and putting it back in, my tablet reads it and tells there is an unsupported filesystem! Then immediately asks me to reformat.
I'm constanlty reformatting with the built in formatter on the tablet and it still happens at least 9 to 10 times a day.
Very frustrating when your using an app that located on the SD card and it unmounts and all my data, even the app dissapears and has to be reinstalled.
I'm rooted running clockworkmod on the sprint factory 4.4.2 firmware.
Any help with this will be much appreciated, my class 10 Samsung 64gb is useless when in my tablet now.
Works perfect on my S4 and S5!!!!
Happened as soon as I locked the screen after creating this thread! Why the hell is this happening?!?!?!?

Hello guys! Just wondering if you could help me...
I bought a SanDisk Extreme 64gb SDXC card and when I place it in the M9 it doesn't recognise at all. It doesn't even give me the option to mount - it's as if nothing is in there.
Strange thing is it works perfectly in my PC and Mac and even detects in a very old HTC I have lying around. Also, if I put an old 2gb card in the M9 it recognises that perfectly.
Anyone got any ideas??

Format it into a different format, exfat. Try fat32 if that doesn't work.

Maybe try formatting it directly from the phone (I didnt have to, i used the PC with a card reader), but wanted to let you know it works fine for me.

That's the exact one I have. I can't format it with the phone though because it won't even detect it at all. Not even allowing me to mount it. Just states it as unavailable in storage settings.

Umm it's very strange. Only thing I can think of is whether the partition map itself makes a difference. With a partition manager, I seem to have options for MBR, GUID and others, but I'm assuming this won't matter considering it's not being used to boot anything up? I've left it as MBR because that seems to be the default. Have also scanned it numerous times with PC and it seems to have no bad sectors. I would return it and try another but obviously the fact that it works in every other device I have tells me it isn't actually faulty.
May just have to bite the bullet, buy another and hope for the best. Does the class rating make a difference when purchasing these things?

Shoved it in another Android phone. Recognises fine, used it to format it in storage settings. Still won't detect in the M9! Very confusing!
I would return it, get a normal SanDisk sdxc

Not the gold one the grey one. If you say it's defective then they may test it and tell you it's not
http://kb.sandisk.com/app/answers/d...l-to-restore-full-capacity-on-sdhc/sdxc-cards
I had a similar problem with a 64gb regular sdxc sandisk. I did the entire low level format and electronic partition check. Try that before completely giving up.
hey there xda peeps!
I know there are like a dozen of posts like this, but my problem seems to be slightly different from everyone else's.
when I insert the sd card into the phone, nothing happens, and the phone doesn't scan it. however, it seems to detect it, as I can still scan the sd card using sd insight.
when I go to settings>storage, the option to mount the sd card is available. however, when i click on it, a window pops up asking whether I would like to format the card or cancel the operation. if i click cancel, the window goes away, and I can click on the button once again. however, this causes the storage page to freeze, while displaying the notification"preparing external storage..." if i select format, it formats the card and...it goes back to square one, with it not being detected.
I have read other similar threads, all of which were resolved by pushing in the sd card slightly, formatting the cache from recovery mode and changing the card's storage system to fat32. I have tried all of them numerous times, but to no avail.
I am quite certain it is a software-based issue, as my other sd cards which I know to be readable could not be read as well.
my sd card is a sandisk ultra 32gb, while my phone is a zenfone 2 ze551ml. my phone's software version is in the attached picture.

Does the card work in another phone or on the PC? You might have a bung sd card which is not unheard of...
You could try another sd card in the phone, might be a warranty fixable problem (unless you have fooled around with it)...

yep, the sd card works in a pc. tried other sd cards, they don't read either. and I think my warranty just expired, but I left the phone completely stock.
What makes you think it's a software issue? If no card is working with just that phone, you could very well have a bad card slot.

it seems like a software issue to me due to the problem arising after a software update quite some time back. my phone was functioning all well for about a year or so before this problem popped up. sorry for the extremely late reply.
So I recently flashed the marshmallow resurrection remix ROM on my M8 and it was cool...been using it for some time now...no bugs whatsoever...until I decided to insert an SD card for the first time ever since the flash...as usual upon first insertion it tells you to format it into either internal storage or the other option (forgotten the main terms they used)..now I already know that there's an SD card bug on all CM powered Roms..but the way the error occurs on my device is abnormal...after I select how I want it to be formated and start the formatting process it immediately crashes in like 2 seconds and returns to my home screen leaving this error code

I haven't seen that particular error. When I've had problems with CM13 reading the SD card, what sometimes works for me: insert the SD card into a card reader attached to my Windows PC. Then Windows pops up a dialog box, which indicates there is a problem with the card, and you can pick whether to fix it. I forget the choices, but there is a quick one, and a slower one. I pick the quick one, which just takes a couple minutes; and also preserves the data on the SD. Then re-insert SD into device, and CM13 seems to read it fine. This doesn't always work, but often does to fix the problem with CM13 reading the SD.
May or may not work in your situation, but just throwing it out there, as its worth a try.

But here's the thing...I placed that same SD card in another M8 using the ViperOme lollipop ROM and it seemed to format and most as internal memory or external storage just fine...so I'm sure it isn't a hardware problem

Removable storage is what you want. I'm pretty sure you'll run into problems if you try to format as internal storage (it becomes a part of the internal storage associated with the other M8) and swap the SD to another phone.
Why not try what I suggested, just to see if it works or not? It just takes a couple minutes, so it couldn't hurt. That is, unless you don't have a card reader connected to your PC.
Just tried your way...still giving me the same error...it crashes immediately when the formatting process starts...don't even think it even gets time to initiate the process..could it be that this particular ROM is bugged?

If you try another ROM, and don't get the problem; than its pretty likely a bug in the ROM. But on the other hand, if its a problem with the ROM, I would think that others would have reported it in the ROM thread.
Is your firmware up to date?
