So when I got my S4 I had a 32GB sandisk card (don't know what class it was, came with my HTC thunderbolt). Needed more room, so I bought this. My sd card f*cking unmounts 4/5 a day. When it does I have to reboot it and take it out until it fixes itself. Then it'll go a week or two without any problems. My 32GB sd card did the same thing, just not as often, and I gave that 32gb sd card to my girlfriend who got the AT&T version of the S4 and it did it to her a few times, she accidently had the phone format it, now she has no problems... the 64gb is formatted to exFat, I'm in the processs of formatting it to fat32 and transferring data as we speak, but am I the only one with this issue? I read on the CleanRom thread that S4 have issues with SanDisk brands, someone said they switched to Kingston becauee their S4 wouldn't mount their sandisk.
Is it software / root related? because my girlfriend is stock unrooted and hers works fine and it's an older card but it's also not the same size or class (honestly I know it's not just asking maybe there's a mount issue with debloated firmware) Or is it a defected card/phone?
The card itself is fine. Reads fine on my pc. I checked the sectors and partition with Ubuntu gparted utility and it passed the tests... but I still heard they can be defected and it's a big problem and they'll replace it.
Anyone have a 64gb sandisk class 10 and wanna give me their experience?

My advice is don't format the card to fat32 as fat32 causes data loss over time. Had it happen to me. Stick with exfat
Mine does the same thing...64gb...damaged or it unmounts. Not sure what is going on. I'm almost thinking its a software issue or incompatible with this phone. Never had this issue with my S3.

TL;DR: Buy a class 4 SD card
I bought the S4 on day 1 and started having the unmount issues with my 64GB SanDisk Class 10. When it started messing up my Spotify, I knew I had to try and figure it out. Well after testing with 4 S4s (2 of them mine as I returned my first S4 because of this issue), and a bunch of SD cards, I really think it comes down to the class. Class 4 provides a faster random write speed than 10s do, and I think that might help the issue. Both class 4's that I tested did not (and have not) unmounted once yet.
I bucked up the cash and bought all of these cards brand new for the testing. I ended up returning the Class 10's that I could and keeping both the Class 4's - 1 for a co-worker.
SD Cards Tested:
SanDisk 64GB Class 10 (x3) - One was brand new
SanDisk 32GB Class 10 (x2) - One was brand new
SanDisk 64GB Class 4 (x1) - Brand New
SanDisk 32GB Class 4 (x1) - Brand New
I have an open case with SanDisk and they are testing one of my 64GB Class 10's right now, and then are supposed to send me back another new 64GB Class 10 to help solve the issue. Pretty sure that one is going to unmount too though :silly:

Try fat32 no issues so far, but you're right I think it's an s4 issue because my brothers note 2, my two friends note 2, and an s3 all used my card fine with no problems.

Could be the class 10, but at the same time the class ten is the only one that comes with exfat, correct? I'm thinking it's a software glitch with 64gb exfat cards. Thanks for the info though.

Idk about your unmount problem, but u suspect bad card, I just got my 64gb replaced that had an issue like that.
Fat32 is only bad for 64gb cards because fat32 apparently doesn't officially support file systems over 32gb. 32gb cards obviously don't have that problem.

Hello,
I'm now on my second 16GB micro SDHC card, the first one by CoreMicro, and this one by A-Data and both are having the same problem. My Rhodium, with a stock rom, will stop detecting the card after a random period of time, or really quickly if a program is constantly accessing the memory card, such as with music or an audio book.
This has never happened with my 8gb Transcent micro SDHC card, and since its happened twice with cards from 2 different manufacturers, i'm thinking its not the cards, but the Rhodium itself.
Does anyone know of anything that might be causing this problem or how to fix it?

Thank you for that. I guess we can add 2 more brands that dont work: A-Data and CoreMicro. Sigh...
Did you format the card accordingly?
Google panasonic sd format. Use that program as it formats the card correctly using the correct allocations.

Good I just bought one. Decided to buy it over the transcend although my transcend 8gb worked better than my adata 8gb. Seems to be the opposite going on by what people have been saying on the thread. Will check back in if there is a problem with it.
I have been using a RiData 16 GB Class 6 for over a month without a problem on a Telus TP2
I would think it is a problem with the TP2.
I used my Adata 16GbC6 in the TP2 and had problems. Stuck it in my Canon camera and had no problems with it at all.
RMAed replacement arrives from AData today. Will see if I did in fact have a fault card. Doubt it.
I have a Verizon TP2 and am using an A-Data 16GB class 6 card with no problems. Heck, I didn't even format it before use.
I am having similar problems with a sandisk 16 GB class 2 on a Verizon TP 2. I'd like to try a newer Sandisk however to see whether that helps it. I can't find any class 6 Sandisks though. Are they not out yet?
I had a sandisk 16gb card which was fine, but somehow it got corrupted so I bought an ADATA card. it works fine EXCEPT I CANNOT flash roms off it. my device doesnt see it at bootup. very strange (so I have to install ROMS off an older card).
Any thoughts anyone?

I can confirm that I am having the same problems with my a-data 16 gig card class 6..

The transcend card and sandisk it works like it should.
Anyone else have this problem from a-data
my newly bought 8gb class 4 sd card keeps un mounting so I wish to upgrade it to 16gb card.
so I want to know whether class 2 card will work properly or will I have to get class 6
Class 6 would be the better and costlier option obviously. I am using a class 4 16GB SanDisk card and havent faced any sd unmount issues till now. try using a different rom. i heard it mentioned somewhere that some rom's precipitate more sd unmount issues than others.
The class ratings for memory cards are like mpg ratings for cars. They are a measure of the card's read/write capabilities. The class rating doesn't tell you if you are driving a Mercedes or a Kia. Cheap cards with high class rating have high rates of failure and corruption. All classes of cards can work with your phone. Get a card with good reviews. Beyond a minimum class rating, you are wasting your money. My class 4 Kingston card has higher read/write speeds than my class 10 a-data.
I have san disk class4 8gb card and it keeps unmounting.
this cars is made in china.
I have another 4gb class 2 card of transcend and it does not unmount at all. this one is made in korea.
Transcend 8gb class 6 never unmounted once.

I have 8GB class 4 card and i had unmounts in stock 2.0 ROM and also in void rom. But now i am on Gyanogen 7 beta6 and no more Also A LOT faster.
Well I'm using 16g class6 from a small brand in Taiwan.But it works very well, with speed r11 w8.
I know it's not that fast, but very stable.
I guess unmounts depend on the ROM, whether you're using Apps2SD and the class. I had unmounts on void with Apps2SD. Quite stable with Cyanogen so far. Class 2.
Will upgrade it to a Sandisk 8gb class 4 soon. Sounds like a safe bet.
so you recon I upgrade my firmware to 2.2.2 from 2.2?

I don't think 2.2.2 solves the unmount problem. Try a cyanogen mod beta without apps2sd. beta 5 has been stable for me. I hope this will be fixed when the official gingerbread comes out. Create a nandroid and titanium backup just in case. the unmounts were the worst for me with stock lg.
I bought a Sandisk 4GB class 4 card and still had unmounts and freezes. Now my P500 is in repair service...
I had an A-Data 8GB Class 4 .. it was a disaster... multiple errors and reboots on installing program... very very slow. on all Froyo ROMs it was the same. but only on Cyanogen ROM it works without errors and reboots. also the boot process on Cyanogen beta5 takes about 3 minutes that i think it was because of that...
PS. I changed my Memory card today to a 8GB Patriot Class 4... I am testing it right now
PPS. Until now the new microSD works like a charm... no problem at all... it is so much faster and better than A-Data
doesn't divx videos stop working if you install custom rom? I use this phone only for four purposes,
reading books

music
movies
I have a psp for games and another phone for phone and messaging etc
I dont have a computer though, so can't flash either.

I received my phone from LG repair service this week. They told me that they found nothing wrong, so they didn't do anything to the phone. Today my phone had again the "sd removed unexpectedly" message. It will probably have freezes again in a couple of weeks. These guys at LG service are useless. As my phone still has 10 months guarantee remaining, I will send my phone to repair service as many times as neccesary until they give me an acceptable answer or solution.
It's incredible LG doesn't have an official fix for this. Trying a different SD card is not a solution, since the SD provided should work, another SD is not guaranteed to work, and otherwise faultless SD cards are not working properly in this phone.
so I just bought this card cause I use lots of storage space pretty quickly, My question is wtf is going on here? it just sticks on "checking for errors" and never gets past it, it mounted up once and while I was dumping files on it over USB from my computer (in usb mass storage mode) both it and my internal storage just disappeared, the copy operation failed, so I restarted the phone and I have yet to get the phone to mount it since then.
I'm running eclipse 1.3rc2, is this because of the sd flip-flop, the size of the card or the fact that it's class 10?
the card works perfectly fine in my camera, and in multiple PCs, but as soon as I stick it in my X2, it just doesn't want to work.
I noticed the stock SD card has a "bootable" partition flag, whereas this one doesn't. maybe this is my problem?
also what filesystem should I use, I run linux on my PCs so I can do whatever I want with it.
what if I just delete its partition table, put it in the phone and then let the phone format it? I've reformatted it with my PC and no dice.

When I got the 8gb card and using now it was acting weird ...would copy files when in the phone. I formatted it using the phone and it has worked fine since.
Good luck.
I can't say it will work for u but it cured the problems I had at the time.
just make sure u format the right card since in eclipse its switched around and recognized as internal in menu.
well, It took exchanging it for a class 4, and now it seems perfectly fine.
so note to self (and others)
NO CLASS 10 CARDS IN DROID X2, IT DOESN'T FN WORK!

I don't think that is true...I thought I saw plenty of users say they use them.
Mine is class 6 and works just fine
Did u try formatting from in the phone while stock? Don't know if that would make a difference at all
I didn't read one single thread from someone successfully using a class 10 card without having issues, sometimes it took a few days/weeks, it only took me one mount/dismount cycle.
besides, the class 10 cards, while having a higher sustained transfer rate, their seek times and random access times are overall slower. basically these class 10 cards are ONLY good for digital video cameras and things that don't actually utilize a filesystem.
that or they're getting cheap chinese cards that are just remarked class 6 cards, the X2 can't read and write to a class 10 fast enough resulting in data corruption, period.
Yeah im not arguing
I understand what ur saying now
I can confirm class 6 being completely fine tho
I think the "issues" I had was the file size I was trying to transfer(4gb)
I don't think it's the class rating but the capacity. In my experience 32 gb cards just aren't as reliable as smaller-capacity ones. Perhaps it's a consequence of packing too many memory cells into such a small form factor, I don't know, but I've had three 32 gb micro-SD cards fail on me since the beginning of the year, whereas not a single 16 gb card has failed me yet.
I just dumped 4.8gb of crap on it, over usb and it took it like a champ, it's also significantly faster than the stock 8gb card in terms of mounting, remounting, scanning my media and even opening up fileexpert is faster.
class 6 i'm sure is fine, probably the best balance, but I can even take HD video straight to this card with no frame dropping or glitching. it's currently playing hd video on my hotel room TV right off the SD card w/ no issues (the stock 8gb couldn't do that)
Ha. Mine came wit a 2gb class 2 sdcard ...
Wait...now that I think about it.. I had bought a droid pro initially. It had a screen issue...I took it back and paid extra to get the x2. Then I told em I didn't wanna lose my pics/video I had taken and he switched the cards. So I guess he basically just kept the one I wax supposed to get instead of moving my data to the new one....prick...

It is speed. Sandisk has the fastest random write speed which is what seems to cause those lock ups. SD card class is just measures one (relatively unimportant) indicator of SD card "speed" (sustained read).
Sustained read and write are great if you're using your card to backup large media or picture files but more or less worthless for running an operating system. Same principle is in place for SSD. Manufactures advertise sustained transfer rates but the important stat for a OS drive is access time (which determines the speed of random read/writes).
Here's a link to a 32gb sandisk for $30 http://slickdeals.net/da/mem-i/p46847290/k4569/u125110/r4
These work just as well as the 16gb ones.

32gb is theoretically the maximum, since 64gb cards will all be part of the new SDXD standard. Then again, several people have found that the 64gb SDXC cards work in their SDHC devices so we'll just have to wait until someone tests one in the nook color to know for sure if it'll support it (I wouldn't hold your breath, our hardware is fairly old).
I can certify that the 32gb works fine, as can numerous others who I've seen post.
I'm using a 16gb card now but I want to upgrade to a higher capacity. I don't really know the difference between Class 4/6/10 or the different types out there. Also, does the S4 actually support 64gb and had anyone got it to work?
Thanks ahead of time.

The 64 gig works fine once you are booted into Android.
There is a huge difference in classes of cards. I wouldn't buy less than a class 10. I would suggest a class 10 "pro" that has read speeds up to 70gb/sec. I had a class 10 sandisk that was 64 gb in my phone. I just learned that my backup clockwork recovery will not access a card over 32 gb. I just bought a 32gb samsung class 10 pro card from Amazon. It was nearly $50 but the speed tests on it are much better than the old class 10 sandisk. If you plan to root and use custom recoveries and ROMS, I would definitely suggest a good 32gb card. Hope this helps.

if you're planning to go 64GB, it comes out of the package exFAT. Some ROMs and custom recovery does not read exFAT and needs to be formatted to FAT32. As mention, get class10 due to transfer speeds.
Samsung 64gb Class 10 Pro
Old thread but just an fyi...
I bought the Samsung 64gb Class 10 Pro and it did come formatted exFAT.
Just to see what worked and didn't work, I left it like that and copied all of my music, data, videos, etc. and put it in the phone and everything worked great with one exception. CWM recovery doesn't read it, I was bummed because I am a die hard CMW user.
I went ahead and installed TWRP and it reads the card fine, I have made a complete backup and then a restore and all worked well.
Guess I will get used to TWRP
Hmmm so Samsung Pro card over Sandisk?

I thought it was custom kernels that had the problem with exFAT due to licensing (and not open source). Not meant to exclude CWM as I understand there is an issue there as well.
Just format the card fat32
Here is a good explanation of the differences between the different formats.

So...if you guys could get a 32GB microsd for the S4, what would you recommend?
