Hi all,
So my SD card recently kept unmounting itself from my phone, and I've been allowed to get a full refund as it's a known compatibility issue with SanDisk cards and S4.
The problem here is that I cannot format my card using most means (through PC, MAC, Phone, and DSLR). The card is currently using exFAT. It mounts to my system fine, I can see all files stored perfectly, although whenever I delete the files individually and remount my SD card, all the files appear again!!
Through PC, I have used Disk Management, EaseUS Partition Manager.
Through MAC, I've used Disk Utility, SD Card Formatter v3.
At the moment, i don't feel comfortable in sending it back, with personal data easily accessible.
Anyone have any other methods / ideas?
Thanks!
GUIFormat ?
Same issue here. if anyone finds a solution pm me or reply
Sandisk messed up and make faulty card. It seem this only happened to 64gb SDXC card. I already had mine replaced under warranty 1 time and then after a while it's acting up again. So I ditch that card and buy the other brand.

I just recently bought a SanDisk 64Gb MicroSDXC. It's driving me nutts since last night! First I discovered that the phone cannot mount it if it is in exFAT mode. Then i Download a Verbatim Utility Program to format it in FAT32. I thought it was finally ok, I tried transfering some files both via phone plugged-into the pc, and with the card removed from the phone and connected to the pc via card reader. Last night I was able to transfer files from my computer, but when I check it within the phone, it seems it cannot identify the contents nor the folders! I tried resetting it, with and without the Card, but the problem persists. Not only that, it seems that the phone automatically unmounts it at random times!
If anyone can help I would highly appreciate it!
Try to use SD Card Tester to test it.

My 64GB Sandisk Microsdxc worked fine out of the box, although it unmounted itself once when I rebooted.
Like alot of you, I recently had alot of trouble with my sandisk 64gb micro sd card. this fix is pretty easy but it worked for me! so check it out:
you need two programs: SD formatter( can be found on the sandisk website) and easeus partiton master( you can use any program that lets you format partitions)
you will also need the sd card adapter to put you micro in, and an sd card reader
Step 1: connect your sandisk 64gb microsd card to the computer with the adapter it came with in the box. My laptop has the sd card reader built in
I dont think it will work unless you connect it this way.
Step 2: open sd formatter, it should have recognized your card if not click refresh. after its recognized click Options and set format type to full (overwrite) format the sd card. this will take a long while so you might wanna go watch tv or something?
step 3 : after its done formatting open partition master and right click on the sd card and format it to fat32. your going to have to click apply on the top right hand corner for it to work
you should be set. DONT FORMAT IN THE ANDRIOD SETTINGS. for some reason when ever i fixed the micro and tried formatting it in my phone it would mess up everything thing again.
I keep a 32 gb in my s4 now and use my 64 in my note 10.1 because i need the space there more. Let me know if this works for you!

It really depends on the troubles you have, most of them are some kind of incompatibility with the S4 firmware and the 64GB SD card and formating this will not help. My issue was each time i'd put music on my SD, my system status would trip to custom, also my music would not always show up at boot. This has been a recurring problem with the sandisk cards no matter how i formated it. And yes, i did use SDFormater 4.0 and still had the issue. My only solution was to get a Samsung 64GB SD and no issues since
Sometimes mine removes itself, but a media rescan or reboot fixes it. Doesn't really bother me.
I use a 64gb PNY class10 and its flawless for me.I think the issue is witg the sandisk bran.

Figured this is a good thread to post my experience.
I had a MicroSD card I thought was bad. What happened was I was formatting the device to ext4 at the time using a older microSD USB adapter i had. Basically, the microSD card reader died while it was in that process. Using a microSD > SDAdater and a built in SD card slot on my laptop I was unable to format the drive in Windows or MacOS. (I was formatting the device via the USB reader on my Desktop in Ubuntu). Ubuntu does not see my card reader on my laptop so I was unable to use that). I thought I killed it. It was a SanDisk microSDXC 64gb card.
So I ordered a new Samsung microSDXC and a new microSDXC USB card reader. I got them both. New card worked great. I decided to play with the card a bit. Using Ubuntu, gparted specifically, with the new adapter I could no create or modify partitions on the old microSD card. It would fail out every time, different errors for ext4, exFAT and Fat32. So. In Gparted I went to Device > Write new partition table.After I did that I would able to format the drive in Ubuntu to whatever filesystem I wanted, and the card works in the phone, mac, windows, everything.
Just a heads up to help any others with issues. Rewriting the partition table may help if somehow it gets corrupt because of some write fail,
I ve 2 64gb sandisk 10x microsd with Samsung S4 I9005 with Android 4.3. I formatted with android, also Windows 7 64bit with various types of sizes on laptop. However on laptop or on phone after writing some files and disk scanning, it gives many disk errors. I wonder if it is software or microsd hardware problems. There is no problem with 32 gb.

Found the Culprit!
Considering I encountered this write protect error TWICE with the exact same product, and after having read forums that show it's a common problem, I conclude that the problem is with either this specific SanDisk product or a particular batch of this product:
Exact product specs: SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 Memory Card with Adapter (SDSDQU-064G-AFFP-A)
These carry a lifetime warranty. A word of advice: if you go for a replacement, ask for a different 64GB model, or try a different size of the same model (I got 2 x 32GB cards instead). If they insist on giving back the exact same model, I'd suggest you use that card anywhere except a smartphone!
Hi Everyone
Any ideas why my Moto X Play would not even see my brand new MicroSD Card?
It's 128GB and so far I've tried it formatted as both EXFAT and FAT32 and no dice! It just doesn't even see the card.
Anyone have a guess at what gives?
**Edit**
So I've tried multiple sizes and brands of SD cards and none of them seem to be detected by android. Also tried resetting the device and no dice. Looks like my card reader may be borked.
** Edit 2**
I ended up having to return my device, as the card reader was pooched. The store simply did an over the counter exchange.
Can't see any reason why it wouldn't work. Maybe the card isn't mounted properly (in the wrong position) or as you said, you may have a faulty card reader on your phone.
I may be suffering the same issue. Have you been able to achieve anything regarding this?
I ended up having to return mine. The SD card reader was dead as I had suspected.
if you can format the sd card that means your phone see's the card and you can choose weather if you want to format as internal or external i like it internal but you have to get a faster card for sure and if you switching card from 16g to 32g....ect you have to forget the latter card then you can restore all your files. it worked for me.
Hi all,
I have a Galaxy S5 (SM-G900W8) Canadian model. I purchased a 128GB sd card and I'm running into some issues. My S5 can detect the card, and I can copy files to it. But it seems that one I hit roughly 8.08GB of used storage, anything more I add disappears after my phone reboots.
The card was formatted in FAT32 originally. I have tried exFAT but the phone is unable to read the card in this file format. I have also tried NTFS but same results as exFAT.
I have done some research and have seen others with issues regarding 64 and 128GB sd cards with Samsung Galaxy models, but no fix yet (or at least from what I've seen/read).
This card only seems to work in FAT32, but I am unable to use the full capacity of the 128GB sd card in FAT32.
I have a 32GB sd card that works just fine without issues. Not sure what file table the 32GB card is formatted in though as I did not know of this issue until recently when I discovered it so never bothered to check.
Is there a fix for this that I have not found yet? This is quite annoying.
Thanks
Probably a fake.
i dont have problem with Team MicroSD 64GB
you have to format it in your phone (ExFAT), use file explorer in your phone, do not format using PC

What sd card is this because it seems like it's a fake and may not really have all that storage. I've never had any problems with my 64 gb SanDisk micro sd card which I'm currently using.
try PC format

I downloaded the tool and just used the cleaner. I found problems and then I ran clean & fix and it seems to have solved the problem. Thank you very much.
Hi everyone,
i have a G900F running on the current version of the ALEXNDR Rom, rooted, Knox 0x1, Android 6.0.1.
I have my SD card formatted as (mixed) adoptable storage (via adb), so I have 50% of space as SD card memory, 50% as adoptable storage.
And now for the problem: The SD card is repeatedly shown as "damaged". As soon as I put it into my PC, it'll work without any problems, but the SGS5 will work for quite a time with it, and then suddenly shows it as damaged and will not mount it unless you format it. It usually happens when a larger amount of data is written to the card.
So I thought that the card might really be damaged (was an old and small and slow one) and went vor a SanDisk Extreme 64GB card - same thing here. Then I read about some problems with Samsung devices and SanDisk cards (may the be true or not, I dont know) and swapped it for a Samsung 32 GB Pro SD card - same thing here.
Does anyone know why this is happening and how to stop it? Or will the adoptable storage just not work?
In addition: I could reproduce this when I was downloading Videos to the SD card from Amazon Prime Video for offline use. Seems that a) this is a large amount of data and b) split into thousands of small files. I dont know if its the number of files or the amount of data, but when I deleted the folder on my PC and put the card back into the phone, it suddenly worked perfectly again. Any ideas on this?
Hey there how are you?
I recently have had an issue with my samsung 128 sd card that was formated in a 50/50 mix from adb too.
As the sd card was formatted in exfat I posted an issue on the exfat home page. https://github.com/relan/exfat/issues/49 I was provided with advice on my mac on how to reformat it using the dd command. This was the only command that I came across which gave me an input output error indicating a hardware issue on the sd card.
I have since purchased a new sd card. I'm thinking of formatting it as either an ext4 format or f2fd format to see whether this makes an impact of its longevity.
Hope this helps.
