Sandisk 64GB MicroSD not detected by stock ROM. - Verizon Samsung Galaxy S 4

I've got a brand new MicroSD, but when I insert it, the ROM never detects it. The storage menu says to insert a card, but I've tried many times to remove and reinsert it. I saw problems like this with the S3, but I've never experienced it. Common issue? Ways to troubleshoot?

There are youtube videos explaining how to install micro sd cards and how to make them work. Just type ( micro sd card in samsung ) its easy.

You probably just need to format the card before you put it in your phone. Connect it to a card reader to your computer, and check what format it is. Either FAT32 or exFAT are the ones to try.

Thanks, I'll give it a look. I'll be surprised if it was NTFS out of the box.

I thought 64gig cards come formatted as exFAT which don't work in the phones, and you have to reformat them as FAT32 in another device that supports it, then put it in the phone.

Pretty sure this is exactly what the problem is...

I got a SanDisk 64 GB card, put it in the phone and formatted, and it works fine.. *confused*

I couldn't remember which was which, I use exFAT in my Note 2 but I'm running a custom ROM. It's probably FAT32 though, and I know I couldn't format it on Windows 7 using Explorer as it only allowed me to format it as NTFS or exFAT.

I think I may just have a dead MicroSD. Not being detected by either of my laptops, so that would explain it.

There is an program you can download to format fat32 >32gb on win7. Think it's called guiformat or some such.

It supposedly works. I have a 64GB sammy card on the way.

Already used it on mine. Was waiting on the swap mod to drop for the S4 before I replaced the 32.

You have it backwards.
Stock Samsung kernels all support exFAT now. Unfortunately because of Microsoft and licensing issues the code for this isn't in the Open Source release. So if you ever go AOSP or custom TW kernel, you have to switch to some other format.
By the way, the Samsung 64gb cards are testing way faster than SanDisk. At about the same price, get the Samsung.

Should we expect the S4 to have the same problems with MicroSD card failures as the S3? From what I've read so far SanDisk claimed responsibility for the problem yet folks here were talking about exfat being the problem. Did the exfat compatibility issue get fixed in the S4?

exFAT is and has been rock solid since Samsung's 4.1.2 or so... and since the S4 is on 4.2.2 to start, it's fine.
SanDisk has still been having issues, though, and given that and the speed difference I'd suggest buying Samsung microSDs in the first place.

Upgrading microSD from 16GB to 32GB

I decided to get a new larger microsd and it just came in.
Can I just mount this on one of my Linux boxes and copy everything over from the 16GB to 32GB one or is there something special which the Note does with it?
I have SD and USB adaptors so I can actually mount both devices at the same time.
I don't see why not

Well... the 16GB card flaked out upon insertion into SD adaptor and then into Linux box (write lock switch in place). Didn't look any better in USB adaptor on Windows. Says unformatted even when back in the phone.
So everything is fubared.
Not sure what component to throw away either.
Knew I should have manually copied the files while the card was still operational in the machine...
The key to backups is redundancy. If it's important you need more than a single backup.

The card was operating fine in the machine but I had seen some issues recording video and DragonBox+ didn't want to update itself. But it wouldn't update itself on either SD or internal, so I thought it was something else. So I ordered another card.
I actually found this card in the park in an adaptor last year and was surprised it even worked. I went to the trouble to save off the previous person's data in the hope of being able to return it to it's owner, but couldn't fine any identifying name address information.
The photos and video should all be synced to Google+ - I'm more annoyed about having to go and remove all the apps and re-install because you can't just refresh the install over the missing files on the SD.

I was amazed today to find that the new microsd seems to have all the files on it (11GB worth of files)! A friend thinks that the backup feature restored all the data overnight.
Oddly, ES File Explorer seems to indicate that the card only has 16GB, though. So I'll have to do some more digging tonight...

64GB MicroSDXC working

Hi everyone, just wanted to confirm that 64GB MicroSDXC cards do work. I bought this one http://www.amazon.com/dp/B007WTAJTO/ref=pe_175190_21431760_M3T1_ST1_dp_1
At first it will not work, but you must format it with the phone and it will work well. Reports 59.6 GB

Doubtful...sold by Amazon.com LLC. I don't buy eBay shiest unless I can't find it on amazon or somewhere that either accepts google wallet or is within driving/shouting distance. Still though, I took your advice and downloaded H2testw and will run the test tonight.
Thanks for all the ideas guys!
That used to happen to me, got very frustrated because I could never copy things to my flash cards. Turns out the problem was my card reader. Try getting one of the USB ones that can actually read SDXC. I don't have one, so what I did is put it in the phone, then connect via USB to the computer in mass storage mode and it worked great.
I had the 64GB SDXC as well, it at first seemed to work, but don't be surprised if it stops working. Motorola, and I believe stock Android do not support SDXC yet. I have a somewhat detailed thread here: http://www.droidforums.net/forum/dr...d-cards-hd-maxx-hd-class-10-32gb-vs-64gb.html
When I got my card, popped it in, it formatted correctly, and seemed to work fine. As I started to put it through its paces it started to just not work. On ICS when you used the Storage option to transfer media to the SD card, it would stop halfway through and throw out errors. Eventually certain apps would stop writing/seeing the card like backup apps etc..
Be careful going forward, and test it hardcore. Transfer files back and forth, I always had issues with movie files. See if Root Explorer or other explorer apps can see it, see if Titanium Backup or My Backup Pro/SMS Backup can see and write to the card.
And yes, I did not get a dud, its works in other non-Android devices and works and tests perfectly in multiple computers. Just be cautious.

These are all the same symptoms I'm having. Well, it looks like Motorola actually had testing and reasoning behind "supports up to 32GB" :-| That'll teach us to think we're smarter than the factory QA guys...
Still though, it's a little disappointing.

Indeed, some of the Sammy devices support the SDXC 64GB card, but I think that's baked into TouchWiz. Hopefully as SDXC gets more popular it will become supported by Android all together. It would be nice to have at least half of my music library on my car so I don't have to stream all the time lol.
Confirmed working with a 64GB SDXC, works pretty well actually, now I'll never run out of space.
I bought 2 64GB micro SDXC cards. One for my Xoom and the other for my upcoming XT925. My Xoom was unable to format it so I used EaseUS Partition Master to format my 64GB cards as FAT32 partitions. So far so good...
I tried my sandisk SDXC 64Gb yesterday with no luck. It was formated to exFat though. I will try EaseUS tonight and try formatting it to Fat32.

I bought a 64 sandisk sdxc class 10 and tried it in the phone. Didn't work. Formatted to fat32 with a partition program, still wouldn't work. Got fed up, deleted all the partitions, threw it in the phone and itr was recognized, but blank. Had the phone format it, and it works. Phenomenally actually. Haven't tested read/write, but I've filled it a few times over looking for problems and had none. Without looking I think I have just shy of 40 used on it right now.
You'd think Motorola would say something about that.
Got a 64gb sandisk class 10 and it's really buggy.
Forceclose/card disabled automaticly/cant see my files/Many lags.
So for me the xt925 is not compatible with it.
I've been using mine for about a year now, it's been working flawlessly. I had to format in my phone the initial time I first used it.

[Q] 64GB Micro SD card issues

Ok, after buying a cheap and corrupted 64gb micro sd card, I went and spent the money on a 64gb sandisk card. It works just fine. Now, I am rooted and have synergy rom build 104 which is also running fine. I noticed before I flashed the rom that cwm wouldn't recognize my external sd card. I read up on that and found that cwm won't read cards formatted to exfat. So, I formatted the card to fat32 and remounted, transferred all my music back onto the card. Everything worked just fine until I plugged my phone into my computer. I was able to open and navigate through the files like normal, except when I went to open the music folder where all my mp3s were. I tried this on 2 different computers and on both the computer froze with the sand timer. The phone itself was fine, my music player(poweramp) was and is able to play the files with no issue. Also, when I unmounted the card and put it into a card reader and then connected the card reader to my computer and voila! Everything was fine, I was able to open the music folder and scan through the music files. I am not sure what the issue is. Can anyone shed some light as to whether this is a phone/rom issue, a micro sd card issue, an mp3 issue? Any ideas would be appreciated.
That sounds like a bad sd card. Have you ran a checkdisk on it?

Hm, been searching around for this exact issue. Coworkers S4 with this exact SD card has been getting the removed unexpectedly error. Reformatted a few times, restarted phone, error comes back. It's in my Note 2 at the moment for troubleshooting, and so far so good, but this makes me move more toward an actual SD card issue in combination with the s4, and not the phone itself.

I called them and they are going to exchange it out for me. The weird thing is that I didn't get any damaged card error messages on the phone itself. It mounted it as soon as I popped it in. Even after formatting to fat32, it mounted right away with no issues. It only happened a couple days after I transferred all my music onto it. Is the free replacement they give you a newer card or newer model number?
+1 to the above. SanDisk told me they have a new version of the 64gig card with updated firmware, specifically for the S4. Package tracking shows mine is to be delivered on Monday.

They told me that too. My guess is it's due to the mass recall of the chips for the S3/S4. They said it's not present in Tablets so my 64GB in my tablet would be fine.
+1 problem with Sandisk 64Gb UH-1 card. Unexpected removal error. I am writing just for statistics. Just got my new Verizon S4 - and have problems...
FYI - I'm having a similar issue with a Samsung 64GD card. Got it to see the music for a while yesterday but after a reboot it can no longer see it.
Update, I received my new card and just popped it in. My phone automatically formatted it to exFAT. I'm not going to try changing it to FAT32, but is there any version or way I can get cwm to recognize the card in exFAT format? I tried TWRP, but when I flashed a rom it soft bricked the phone so I would like to stick with cwm.

Hey bro,
Not sure if this will help, I just got my Note 3, coming from an S4, where I had a WORLD of trouble with a 64GB SD, pictures, backups, data, corrupting left and right to the point where it was un-usable. For now, I popped in a 64GB card I had formatted using my S4, and took a few pictures and videos with it. *Knock on wood, it's been 5 - 6 hours so far, and nothing has corrupted. Not sure if that will change... I am hoping and praying that it won't!
I heard one thing to try (if Fat32 format fails) is to use a Recovery like TWRP and format with that and see if that works? Good luck!

if your having file issues across multiple device YOUR MEMORY CARD is very likely defective. Consider replacing it and until you resolve it do not put anything important on it.
I have a 64gb card in my S3 my Note II and my Note III with zero issues.
If you search the forums, you will find that it must be formatted in FAT 32. You also have to go into settings>wifi.advanced, and uncheck "always scan" or your device will double boot. Been using Sandisk 64GB class 10 since day 1 using above settings, and not one single issue.:good:
Think mine is formatted exfat and is by SanDisk. No problems here.

I have no idea of your hardware, but 64gb is where the switch from SD-HC changed to SD-HC (technically 32 can be either, but generally 32 are HC) and older hardware that didn't explicitly support XC wouldn't work... It either doesn't see it at all or sometimes it will work until you get to 32gb, then you can't write any more data.. I have older SD readers that so both.
But any phone or reader for the last 3-5 yrs handle XC, which has a theoretical 2tb limit, SanDisk has a 400gb microSD.. Insane.
Anyway that's all moot if it used to work in your phone and reader, but just doesn't anymore. Mostly if they're pre-formatted is exFat. If you formatted in TWRP I think it probably defaults to ext4, but TWRP can do a variety of formats.
I got to say though, if you can't reformat it again and TWRP that doesn't sound promising. Perhaps there is an Android app that will let you format with more control than the default tool (I have no idea since the last phone I had with SD was a Droid running GB)
Sorry I didn't really offer a solution, I have had problems with micro SD cards in general with generic brands... But I generally format them in the device I'm using them with and then I have a small USB thumb drive size thing that the micro SD card goes completely inside of and windows generally mounts whatever format it might be, provided drivers are installed.
Also sorry this is so long-winded I tend to do that when I'm voice dictating...
If you have more info that might be helpful drop a line. It doesn't take much to bugger up a microSD card though. Could be as simple as damage (static or physical) when removing it from the phone and putting it in the computer. But the proximity of time when formatted to not working makes that unlikely.
And I'm rambling again.
Cheers.

I have no idea of your hardware, but 64gb is where the switch from SD-HC changed to SD-HC (technically 32 can be either, but generally 32 are HC) and older hardware that didn't explicitly support XC wouldn't work... It either doesn't see it at all or sometimes it will work until you get to 32gb, then you can't write any more data.. I have older SD readers that so both.
But any phone or reader for the last 3-5 yrs handle XC, which has a theoretical 2tb limit, SanDisk has a 400gb microSD.. Insane.
Anyway that's all moot if it used to work in your phone and reader, but just doesn't anymore. Mostly if they're pre-formatted is exFat. If you formatted in TWRP I think it probably defaults to ext4, but TWRP can do a variety of formats.
I got to say though, if you can't reformat it again and TWRP that doesn't sound promising. Perhaps there is an Android app that will let you format with more control than the default tool (I have no idea since the last phone I had with SD was a Droid running GB)
Sorry I didn't really offer a solution, I have had problems with micro SD cards in general with generic brands... But I generally format them in the device I'm using them with and then I have a small USB thumb drive size thing that the micro SD card goes completely inside of and windows generally mounts whatever format it might be, provided drivers are installed.
Also sorry this is so long-winded I tend to do that when I'm voice dictating...
If you have more info that might be helpful drop a line. It doesn't take much to bugger up a microSD card though. Could be as simple as damage (static or physical) when removing it from the phone and putting it in the computer. But the proximity of time when formatted to not working makes that unlikely.
And I'm rambling again.
Cheers.

Well the Windows machine won't read ext4 without third-party software... But I don't see why that would keep you from formatting again. And if TWRP does the same thing, errors out, then I got think the card's had it.
If you're trying to use it in the phone you should leave it in ext4, but if you're trying to use it and windows you could try to format it exFat in TWRP.

I tried changing file system to a different type so that I could wipe it in twrp. But even after I do that, it still says it's ext4 on the pc

Nothing really.
I am curious though. Can you give me specs on the card brand/model/serial?
Also, I have had good results with UFS Explorer Recovery pulling data when nothing else will. I think there's a free trial, but you plobably have to pay for it to do anything other than verify it 'can' successfully recover, not sure, but if it is data that you need, it is good.
I only ask about the card because I found in the past I bought like three identical adata brand SD cards and one appeared to be DOA and I couldn't do anything with it and lo and behold adata had found a firmware thing that they could actually fix and they had a tool that did it.
If you want to go down a rabbit hole there is a sticky XDA thread https://forum.xda-developers.com/showthread.php?t=1355528&page=2 with various degrees of helpfulness. Its a little dated, but the ideas are sound for most of it.
Really i just googled "sd card bad after formatting twrp" and lost 2 hrs...
Let me know if you have any success, I realize this is either about data or just personal curiosity like mine... Because a probably sub $20 card is not worth this kind of investment... And if its a high end part, probably has lifetime warranty..

Did you request RMA?

I'm not sure if they are lifetime warranty or not, i have a couple ultra plus cards from Costco that were lifetime warranty.
Now on the less ethical side, if it's a current model, plckup a new one then swap/return. But obviously thats evil.

I would swap....but my data is on it. Lol. I can't delete ANYTHING on the card. Can't format, or right click a file and chose delete. It somehow got from ntfs to ext4
