MicroSD HC Sandisk 16GB not recognized as 16GB. Memory settings of storage card shows 3868MB. This is occuring on two different AT&T Tilt's 8925. One with older ROM.
Any ideas. The microSD card in an adapter shows up on the PC as FAT32 16GB so can't be a defective card??

Repartition using gparted! If still doesn't work it's a fake one.
sounds to me like a cosmetic non-issue.
you see, the software/OS on the phone determines available space and free space using in-memory counters (variables in a programming language). often, the developer might choose a variable type that doesn't have enough "range" to count up to 16GB. so it "overflows" one or more times as it counts up to 16GB, eventually landing on an overflowed value of 3868MB in your case.
if the card is showing up as 16GB on the PC, it is no doubt a 16GB card. on the phone side, you mention you tried it on two different tilts. did you happen to note exactly which ROM versions they were using (its not enough to say "older ROM")? it might be worth trying another ROM if the mentioned tilts were using WM6...maybe this free space counting bug was resolved in WM6.1 and/or later?
just my 2 cents.
flash a newer rom, a 6.5
I got the same problem with another device... and in the end I found that my card was a Chinese fake! They sell you a smaller card reprinted with larger size capacity... but the inside is still "small"! You can use a program called H2TESTW to check its integrity, however.
I hope you guys can help me with the following problem.
I have bought a 16gb MicroSD card (it says it's class 4) from eBay. I copied the files from my old 8gb card to my PC and from there copied the files onto the 16gb card (I put it in an SD adapter and into a USB-stick/adapter and plugged it into a USB port on my computer).
The copying seemed to go well. But when I put the card in my HD2 it can't find the files it's supposed to find. When I put the card back in the USB stick most of the files are replaced by one with a strange code, so all the files I had copied seem to be gone.
I checked if the card was actually 16gb and it was.
Any suggestions for what might cause this problem?

Two possibilities.
1: "most of the files are replaced by one with a strange code" = You're in the Matrix, agents are coming, RUN
2: You have a dodgy card or a dodgy card adapter.
Format the card, copy files one at a time via active sync. If that doesn't work it's a dodgy card.
i don't want to open another topic... i'm about to buy a 16gb card... what should i look for?... i want something to sustain long video shots... that's why i go 16gb...
so... anyone has a recomandation as in brand or technical details....?
Hi
In my experience when you copy files to any memory stick or card and they become garbage text and can not be found by your device or pc it means it is a fake card and not the stated size. SEND IT BACK !!!
If its cheap its bound to be fake!!
There is a tool online to test memory cards and usb flash drive to prove if they are fake and can hold the amount of data stated.

Hi, that's what I thought at first, but I used such a tool (I may haven't used it the right way though, should check this out again) and it said it actually is 16 gb. If it keeps giving errors it may be fake, I knew the risk when buying the card (it was cheap, but didn't buy it with Buy It Now, just by bidding). We'll seee what happens, if it keeps giving the errors, I may wait until the 32gb is released.
Ok, I've tested the card and it turns out it's defective. So I'm going to ask for a refund. New and more trustworthy 16 gb card already ordered (still a bit cheaper than the soon-to-arrive 32 gb ).
This may just be a case of me being genuinely unlucky in my purchases but humour me anyway!
Like you lot I have an SGS and with all the recent mods regarding sound I like to use it as my mp3 player, so buying a micro sd card for additional storage was a must.
I had a spare 4gb class 2 card lying around so I've been using that for some months. Finally decided to upgrade to a more meaningful 16gb class 4 card.
Ordered one off Amazon through a seller. As soon as I put the card in the phone, it refused to recognise it but my PC, digital camera, old blackberry 9000 and n95 saw it just fine. So I formatted the card in the pc using the downloadable SD Card formatter as some googling suggested this might return the card to a working state. After that the phone saw a 16gb card, so I copied some music onto it, it worked for about 30 mins and then the card died totally. Upon reinserting it into the pc, windows only saw an 8mb card in RAW format and nothing I've done since has recovered the card. Card was dead.
Anyway I contacted the seller who posted me a nice shiny Kingson 16gb class 6 card right away.
New card arrived last night, appeared in the phone straight away as a 16gb card. Great start.
Plugged the phone in, started copying some music on it - the write speed was incredibly slow. I mean really slow, 100mb of mp3s was taking the best part of 3 minutes. Popped the card in the PC, same problem.
I find that I can actually write data to the card till its full (albeit slowly) but once you've written more than around 4gb of data, the files start to vanish.
I know it sounds incredibly stupid but anything written after around the 4gb mark just doesn't appear when I plug it into the phone or the PC. The card claims it is full, but only 4gb of data is visible, let alone accessible. I've done the usual formatting of the card and changing card readers etc etc but the result is the same and this is starting to grow boring.
So, question. Am I just incredibly unlucky in my purchases or is my SGS killing cards? Because I'm quite weary of buying yet another card now.
Funny enough my old 4gb card still works just fine like it has for years.
I know you'll have a FAT (file allocation table) that usually reserves a predetermined amount of space on the card for file locations. But your memory card should not be able to accept more than whats available and should be displayed correctly no matter what your using. IE pc or phone. Kingston are fairly reputable, but is your dealer reputable. There are a lot of counterfeits out there. I don't believe the phone itself is damaging these cards. Since your stating your old trusty card still works like a champ

I have been trying to find the best method for getting a 64gb SD card to work with my phone, and it has not been all that successful. I have formatted in NTFS, exFat and FAT32, all with varying degrees of success. Either copying files over leads to data corruption, or I cannot write from and to the SD card when it is being accessed by my device. Any help would be greatly appreciated.
I am currently running CMPrime ROM v1.1Beta with the included kernel. I have also tried using it with Unnamed Kernel.
I just received my Samsung 64gb EVO MicroSDXC UHS-I card this morning. I popped it into my phone and it asked me to format before I could use it. So I clicked yes and then after that it just worked.
I am not sure what would be different for a custom rom as IU use the offical Lollipop 5.0.2. It shouldn't be much different though.
FAT32 is your best bet. I have a 64GB Lexar card formatted in FAT32 working fine with Titan Prime.
It's possible that something is wrong with the card. Does the card work fine in other devices? What brand is it?
Could also be a hardware issue with your phone, have you tried other cards?
Use fat32 no other file system

I bought a no-name SD card from a Chinese manufacturer, because I figured "why not." I know quality of SD cards vary across manufacturers, but since it's an established technology and relatively easy to make, I thought it'd be worth a chance. Some quick Google-Fu showed that it is not a completely isolated issue related to SD failure.
I have a 32gb card that I'm using without any issues. I'm asking specifically about 64gb, because 32gb seems to be the max size for external storage.

I usually give ROM info, because it is common courtesy for dev communities. I have read that formatting through the device only accomplishes a rather crude job, and that file structures can be unsound. I know FAT32 is the standard, but it is an old format that has size limitations.

I believe you should be able to use NTFS or exFAT with the kernal you're running, though I don't know if there might be any bugs or compatibility issues with some cards. If even FAT32 isn't working correctly, my suspicion if that you have a bad MicroSD card. As a rule of thumb I always buy brand name from reputable sources when it comes to microsd cards. I know those cheap ones look tempting, but the quality issues with them are legit, so it's a real crapshoot.
And yes, you'll run into the same old limitations with FAT32 in terms of file size, etc., but I use it anyway since it has the widest support across devices and I sometimes swap my cards.

I am inclined to call this a bad SD card, but I want to rule out all other possible reasons. Null Hypothesis and all that.
In terms of performance of FAT32, it is registered by the ROM, and it is visible in recovery. But my music files are not readable in Google Music or any other music app. I've tried moving them to /sdcard1/media/music and it is still balls. This kind of behavior leads me to think that it is an actual formatting issue.

Max file size for fat32 is 4GB-1byte. Should be not a problem unless you plan on putting e.g. large hd-movies on the card. Speed isn't affected by the partition type (actually it is, but it's negligible in this case). No-name sdcards are often manufactured with low quality check standards. They sell cards that would normaly get tossed into trash. I use a 64gb card with no problem whatsoever. On windows use http://www.easeus.com/partition-manager/ because windows will only allow up to 32gb. On linux use gparted.

I occasionally save audio recording/mixing sessions as OMF files, which can end up being really large, particularly if I export at 64-bit sampling and 96khz frequency. So the 4gb limit can be a bit annoying to deal with, in that regard.
I wasn't aware about the cheaper SDcards potentially being of b or failed stock. I'll probably buy a new card under a trusted brand, and report back.

Acquired a Sandisk MicroSDXC Ultra UHS-1 64gb card. Tried using it in my android phone. I am able to load files onto the SD card as before, but I still experienced the same issues with Media Scanner failing to account for my music files on External SD. Worse yet, my Titanium Backup files became corrupted when trying to access them via the device. I did a Nandroid Backup and tried a clean install to rule out any potential conflicts with my ROM, only to find that the issues remained, and the Nandroid disappeared from the TWRP backup folder.
At this point, I'm starting to think that it's an issue with the phone itself. WHY CAN I NOT HAVE 64GB OF SPACE, MOTO G!!!?
I bought a sandisk 64gb card off amazon on black Friday, immediately put it in my phone and let the device format it.
Later, I put the SD card in my computer so I could create a 2nd partition for ext4 storage.
The phone had formatted the card Fat32...has been working just fine since then.

When I try to mount the SD card in the phone, it does not register. It only works after I format to FAT32 using TWRP. So I will probably try that.
So 32gb in FAT32, then 32GB in Ext4, and leave back-ups/other files there?
64 card files wont all play
Hi I have a new moto g, I also put in a 64 sd card, while the music files seemed to play fine, video and other files the phone reads some of them not others, I put the same file internally and on the sd card and it reads the internal version of the file. I gather from this forum (though I may be wrong) I need format the sd card, I have no idea how to do that, any help would be appreciated.

My understanding is that, if you have a FAT32 SD Card, then larger files (4gb+) cannot be read. ExFAT and NFTS should solve this problem, but I am still dealing with issues of reliability with my card accessing my music files post-formatting.
Finally discovered the problem. I downloaded SD Insight from the Play Store, and I found that the SD cards I got off ebay were invalid (including the Sandisk SD Card). I picked up a PNY High Performance 64GB Micro Secure Digital Extended Capacity (microSDXC) Flash Media Card from a local computer store, and after formatting to FAT32, everything works.
Moral of the story: buy your **** from a store.
I'm currently using CM 14.1 20161225 with a 32 GB SD NTFS formatted and experiencing some weird problems with Camera/Gallery, Music, etc. when on the SD.
So before I go back to FAT32 on a 64 GB SD I now have I would like to ask if anyone can comfirm exFAT would be working fine on titan CM14.1 or LineageOS?

Sorry no good option when pushing files over and back from Win10 so I would prefer to know exFAT experiences since Win10 should be working fine with it.

That's strange, i have no problems with mtp in win7, looks like win10 doesn't worth updating. Btw, i tried exFAT before and it strangely limited file size to 4 GB like in FAT32.
Note 9 corrupted two sd cards I tried. Lost a lot of movies. I don't dare try another. I reformatted one and it looked OK in the phone but I don't want to reload it and have the same thing happen over. One was a Sandisk, the other a Samsung evo 128.
Right now I'm even afraid to try OTG.
Any thoughts?
Thanks, Rich
Copy your SD Card/OTG contents to your PC,use your phone to format,copy the files back to your SD Card.
FWIW,I have a Samsung 256 GB Card that's been used in several phones over the past two years or so,never had an issue with it in any phone.
I have no idea as to why your SD Cards became corrupted or if it matters who's the mfg of the SD Card,but,just posting what's worked for me.
I would contact the card manufacturers and send them the cards to be check out. As sometimes you may have received a card from a bad batch these sort of things happen. Also take your device to a Samsung Service Center and let them take a look at it.
try using extfat instead of fat32 if not done alredy.
your unit allocation size (block size) might also have been an issue. ive had cards fail in one device but work in an other because of this. played with block size till both were happy. but this was because of fat32 on 128 and up sd cards. extfat got rid of the issues altogether.
also it might have been ejected improperly during a write sequence a few times and accumulated corruption without you noticing it till one faithful day phone decided to access that part and failed miserably.
you could have probably recovered your files with proper disk check or different tools on a computer.
it is strange though that you have 2 failed now. might want to review how you handle and use these. sometimes we want to blame the devices when in fact its ourselves.
im not in your shoes but sometimes its good to reassess ourselves first.
