here's a real puzzler. Today I noticed that my SD card wasn't mounting anymore. I'm rooted on stock ROM. Everything else seems to be working. It won't mount. I've tried using root Explorer and TWRP. Nothing. Thoughts? Anyone?! TWRP sees the card while I'm in recovery. Once I reboot into stock ROM, I lose it. I try to mount it, then I'm getting a 'safe to remove card' notification.

Stupid question, but have you tried physically re-seating the card? I had odd issues like that on my S2.
Other thought, can you mount the card using a PC?
I've tried reseating the card multiple times with no luck. TWRP will see the card while in recovery. But when I boot into the OS, I lose it. I'm stumped.

One random thought, and probably isn't your solution ... Is the card formatted with exFAT or ntfs. Gs4 won't natively support ntfs formatted cards. Plug it into ur pc and check the properties... Worth a shot

If this was the problem would it cause all sd cards to unmount? Or could it just effect 1?
I have a 32gb card that unmounts and remounts randomly. My 16gb card doesn't seem to have the problem.
Im not sure if the 32gb card is faulty or if it has a correctable error. So far formatting it does not help.
The difference between me and the op is that my card will mount, it will just unmount itself at a random later time.

Have you by any chance flashed a different kernel? I believe ExFAT file system is closed source and is not supported by most custom kernels, even if you're still running the stock ROM. If not, can you think of anything that you've changed between the last time you remember your card mounting and now?
Same here, plus viewing media on the card in the gallery seemed really laggy. I switched to a 16gb and have had no lag or issues with the card being mounted. The cards I got are both SanDisk Ultra cards

I just RMA'd a 64gb ultra for the same issue. I started researching....seems to be an issue with the latest Sandisk ultra. I pretty much went through the gauntlet trying to fix it.... Back to stock. Back to exFat, formatted with PC, Mac back to fat, either AOKP, or touchwiz. Same issue. At first it was fine. Then slowly started dismounting and remounting. Then refused to mount...worked around the issue by formatting in exFat, mounting in TWRP.and reformatting... This seemed to fix it for about an hour, I started downloading my music from Spotify...again with dismounting... Drove me crazy...ordered Samsung 64gb

I wonder what is different about those ultras.
Fun note...i put my San disk ultra back into my HTC sensation and it works fine like it has for 6 months. Then i put it in my samsung tablet and it fails there too. And in my samsung phone it fails.
Now i have a 16gb san disk regular card in the phone and it works fine.

OK, so I have more information. I flashed back to stock last night. The card miraculously worked. I was able to format, and store data on it, and read from it. Then I rooted via twrp, flashed Super and the pre-May 7th kernel. Surprise surprise, after a reboot, the SD card is back to not mounting. Anyone have any suggestions?

Same exact thing happened to me with my San disk ultra card. Worked on stock, not on cm.
Was yours the San disk ultra too?

Yes, as a matter of fact. Look up at the link I posted above. Turns out it has to do with rooting and needing to flash a SetUID kernel prior to flashing Super SU. Something in there about exFAT not working. Flashed the exFAT fix and I'm up and running! :thumbup:

My phone is completely stock and unrooted. It's an SGH-M919. I've had it for less than a week.
I too am having an issue with the SD card. I bought a brand new 32gb PNY card, class 10. At first it mounted fine and there was no problem. I transferred files to it from my old 16gb card that was in my Sensation for 2 years.
The following morning, after the phone slept and charged for the night, the card unmounted itself. There was an error message in the notification bar. I tried repeatedly to remount the card to no avail. I reinserted it a dozen times, rebooted the phone several times with pulling the battery, but the card wouldn't mount. I then tried the card in my wife's brand new S4 (we got both phones the same day) and the card didn't work in her phone either.
I then plugged the card into my laptop and it mounted just fine, and all data was still on it. I tried it in the phone again, but it didn't mount yet again. I even reformatted the card in my laptop, but it still didn't work in either of our 2 S4's.
I went back to Frys and exchanged the card for another PNY 32gb card. It mounted in the phone just fine, and again I transferred files to it. This morning, again after a night of charging the phone, the new card was unmounted with the same error message. However, when I woke the phone up, after a few minutes the card remounted itself without having to take it out and reinsert it.
So far it's been about 7 hours and the card has stayed mounted with no issues. We'll see what happens overnight again, when the phone is charging and sleeping.
On the other hand, my old 16gb card has stayed mounted in my wife's S4 with no problems for several days now.
My memory card keeps ejecting itself every time my phone gets the slightest knock, even when I'm trying to be gentle like putting it down on a table. I don't mean un mounting but actually coming out of the card slot.
Any one else having this problem?

I'm also getting that same problem. I tried cleaning the micro sd with an eraser and the holder but i keep getting that message that the memory card has been ejected and immediately the phone starts checking it up. This doesn't happen when i'm using the sd, like when listening to mp3 stored in the micro sd.
Does anybody have a solution for this?

Well all u can do ia format with sd formatter tool and try to use then if prob persist with this or even odr sd then ur phn slot maybe the culprit
I've got Samsung 64gb class 10. Problem isn't with the card because I've tried a few different ones and always get the same result.
I think I've narrowed it down to a little stub on the back cover which I think is supposed to help keep the card in tight. I've filed it off to see if that makes any difference and so far so good.

The PC can or can't read the card? Does your tablet read the card? If so go to settings and storage and try formatting it there first. Then try it in the PC.

i tried it first direct out of package into the tablet. I took a picture with the camera and I was greeted with "Cannot save to sd card, switching to internal memory" So i went to settings, the tablet seems to be reading the card, but not writing to it. So i formatted it in the tablet, still a no go. Put it in my pc and it works just fine. Back in the tablet, it reads, not writes. Back in the pc, formatted in pc, back to tablet, no go.

I've been having the exact same Issue! It's a brand new samsung 64 g class 10 micro sd. Formatted on my tablet. Works when I add files on my pc but in my tablet I can't write to it, only read.
And when I download new apps with the card mounted it has errors, I need to unmount the card just to install an app.........
What did you decide? I can't work out if it's a faulty note, faulty card, or if we just need to live with it?

Damn! Turns out i got a fake too! I messaged the seller and i received a whole refund. I went to radio shack today. $49.99 for a REAL (haha) Sandisk 64GB Ultra sd card. They were very nice about it too. Had to go in the back to look for it cause there werent any on the shelf. As i was pulling out of the parking lot a screaming employee was waving one in her arms haha. Made my day.
Now only if we can get google to allow play store content to save to sd like my phone does.....
Like the title says, picked up an SD card, doesn't show up under the Storage menu or when I connect to PC via USB. I've downloaded an app that lets me format the SD and it shows up there, but after formatting I still can't access or even see that the SD card in installed.
It's a GSKILL class 10 64gb SDXC
Hmmmm. Have you tried a different card to see if you get the same results? I'm using a Lexar 633x 64Gb card. No problems to report so far.

I am having the same problem with a dual sim D858 G3.

Hmmm, investigation with a torch and loupe revealed that one of the MicroSDXC reader pins were bent down.
Managed to lift it with a needle and now it works fine.
This was on a new phone, wonder if other people's problems had a similar cause ?
Format the SD Card in storage settings. It should format and be useable
Try couple things:
1. Try (may be borrow from a friend if you don't have one lying around) a different brand name card. Some generic brand cards (especially from eBay) are little flimsy and does not provide proper contacts. It happened to me on both HTC M8 and LG G3. Tried SanDisk card and all went well.
2. Try formatting the card using PC into Fat 32 format (you can always reverse this formatting to ex-fat) and see if this make any difference.
3. This one sounds very basic but under storage, sometime you have to manually click on "mount SD card".
Good luck!
Ok try this
1- but it in lapttop slot (card reader of laptop ) dont try another way .
2- use SDformatter 4 .
3- ok now put it in your device.
I hope it will work properly

Have spoken to a repair shop and what they said is that this is a typical issue with the LG G3, another one (which I also see a lot) is spontaneous reboots, even when the phone is seemingly doing nothing. And these issues get only worse over time. The only way to solve them is to replace the mainboard, which probably isn't worth it. Looked at alibaba.com, they are around 30-40 USD. I have reflashed the stock firmware in my futile attempts to get both issues solved, but it is obviously a hardware issue.
Yeah stopped working too. I've noticed an issue with a pin in the MicroSD card slot. I imagine this is the issue. I'll open it up when I have time.
Take the card out, insert it in a PC and check it for errors. DiskGenius or MiniTool Partition Wizard can help you here. DiskGenius can also check for partition table errors.
Also make sure the card is formatted exFAT, not FAT32 or NTFS and that the cluster size is either 8K or 128K.
If that doesn't work back up your files, format as exFAT with 128K cluster size, then copy the files back. You may have to do this anyway if a partition table error is detected.
Just received my unlocked 10, t-mobile. Put my 128gb sandisk card in and it works fine, but I keep getting a notification that the SD card is unexpectedly removed. Tried reseating it, still get it. Anyone else?

My PNY 128GB has been doing that too. It would show the message and when I check on it, sure enough, it's unmounted. So I took it out and formatted it in another phone and it's slightly better. I get the unmounted message, but the card stays mounted. I'll probably try a different card tomorrow.
I have same issue with my Samsung 128gig card. Random unmounted status.

exFAT Default allocation should be fine, but you can just format it in the phone. If you run into issues, try FAT32. If you still run into issues, try another card.
I'm going to try a reformat today, see if it works
I've been on a clean reformatted card for about 2 hours now, so far no error. I haven't loaded back up yet though.
My pny only gave me problems when I was writing a lot or something big to the card.
I swapped mine out of 4 different phones, then into this one, so it's no wonder it errored
I have a Lexar Professional 128GB Class 10 and am now getting the same problem.
It has been fine all week but all of a sudden from yesterday morning it has started playing up.
I have tried RE seating and it works for a little while then complains.
I have also found just restarting wakes the card up for a little while so am wondering if it is software related rather than physical?
I don't know, I did a full reformat on my laptop, then formatted it on my phone and haven't had any problems since.
