[FIX] sandisk 64gb micro sd card

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!

64GB Sandisk Ultra micro SD cards not working on S5 and Note 10.1

So,
I understood that I could use up to 128GB on the S5.
If this is true, why Can't I use a standard sandisk Ultra micro SD card of 64GB? The menu shows me I can unmount and format, but that doesn't seem to work. I tried formatting in MS-DOS (FAT) format using my Mac (I don't have windows), which worked for my Note 2 but not my S5.
If I try writing a file to the micro SD card it says: "ERROR, could not write file".
When I try to format using the phone, it says no card installed (despite the card being installed, its size being indicated, the unmount and format options being available, etc).
Interesting, I have a second one installed in my note 10.1 2014 edition, and that one behaves a little different. It is also not usable but it greys out the unmount and format options as if the card does not exist (yet still it indicates the available size). Note, for this one I also used the MS-DOS (FAT) formatting method on my Mac.
I know the micro SD cards for both the S5 and the note 10.1 2014 edition are both ok, because I tested them on my Note 2, which reads and writes to the cards perfectly fine.
Both the S5 the tablet and the microSD cards were bought on Singapore Airport.
For info, the tablet runs 4.3 and the S5 runs 4.4.2 straight from the box.
Can someone help me with this?

So I found for the Note 10.1, if I format it with my Note 2, it accepts the card and I can use it normally.
The S5 does not do this, so I suspect this is another major issue with kitkat 4.4.2 (I also have VPN issues with 4.4.2 which I don't have on 4.3)

I have the same card you have in my S5 (it was in my S4 before). I have no issue with the card. But I cannot use other app than the stock file manager to write to it. This is a Kitkat issue though.

i have a 64gb sdhc and i get the error icon on pic and videos when i try and transfer from laptop, phone storage to sd or any type of way the s5 will show the crash icon on the pic and wont view it. Ive used a new 64gb sdxc and 64gb sdhc both did the samething.

I've had 2 of the same genuine SanDisk 64gb cards fail in a similar way on my S3 because I tried to format in Fat32 so it would work with directory bind to move data to external but both times it killed the cards and only a few formatting programs even recognised the card in the end, So this time I'm taking no risks and the card was formatted in S3 then S5 and has gone nowhere near a PC and has run perfect for over a year now.

And I regularly put my Micro SD into a PC to copy files without issue.

Just try to avoid formatting in PC because that's where you might get the problems... And anyway I just backup on flash drive through OTG because it saves all that hassle of installing drivers on everything and sitting at the computer or removing the card most days.

I have the same problem here. I have two microSD Samsung 64GB class 10 original (one of these I got on the launch event of Galaxy S5 at Barcelona). Before S5 I had a Galaxy Note 3 and it worked without problems. So I changed my phone to a S5 and both can't be recognized in it. So I bought a 32 GB Sandisk 'cause someone suggest an incompatibility with 64 GB / FAT 32. On the microSD slot, the phone won't recognize it. At USB OTG, S5 recognize only the 32GB... both of 64GB still can't be recognized. WTF?
And yes: all the SD cards can be used normally at PC, W10 tablets...

[Q] Weird MicroSd issue

Hello world,
I'll try to make it as short and accurate as possible. I have an S5 SM-G900F and until recently I was using a 32 GB micro sd card (formated in Fat32) that i had on my S2.
A while back the card just unmounted and died (i tested in another phones + on 2 pcs through card reader).
1st i bought a 64 GB card on ebay (a cheap one) and when receiving it I had 2 issues: the card was slow to read/write and no matter what method was used and how many files were transfered, after a reboot it would only display the first +/- 7.5 GB. The remaining folders remained, but with no files in them. I thought the card was defective and got myself a new one but went for a 128GB this time Read/write speed were correct but i still had this +/- 7.5 gb limit on it. I do not have any phones to test this time, due to the capacity, but on several computers, the size of the microsd card was correct and when connected through USB OTG when i had more that 10gb files on it, they displayed and played just fine (movies and music). It appears that the phone just "deletes" files going over the 7.5 GB threshold. I used the following methods to copy files to the card:
1. USB cable and MTP.
2. Card reader
3. Over wifi using ES File Manager
I thought that maybe the stock kitkat rom i had was the problem so i upgraded to a stock lollipop 5.0 (spanish one) but i have the same issue. I even tried unrooting the phone.
Has anyone ever encountered this kind of issue? Does anyone have any suggestion to try resolving this?
Feeling desperate here

can anybody help? please

Hi :good:,
Sorry to hear that you are faced with a Defective SD Card. Stop buying from ebay as the sellers most of the times are not authentic and the electronic products you buy will be fake from inside but looks absolutely genuine from outside.
Currently ONLY 'SanDisk' and 'Samsung' produces 128GB mmc card.
Try to reformat the Card as Full Format in Windows and check if it works.
if not then Delete the Card partition from Windows. Put it in the phone and it will be identified as Damaged Card. Go ahead with clicking the message and the Phone will Auto Partition and Auto Format the card.
If its still not working... then you are married with a Damaged Card.
Check if you are accessing the SD Card Folder over WiFi not the Phone internal memory Folder which is anyways will be much lesser. KitKat do not allow accessing the SD Card to 3rd Party Apps but there are few tricks here in XDA (search for it) which will overcome that.
Happy Troubleshooting.

External SD card issues

Hi! First of all sorry for my english. Not my best language.
I'm having issues with external SD card on mi note 4 (910H). On KitKat I noticed that some files became corrupt after some time (mainly pictures and videos). Now with lollipop I thought that the problem was solved, everythimg was ok, but now I'm facing the same issues with corrupt files. It seems that mostly everything copied to the SD card becomes corrupt or damaged except for some small files. I've formatted it several times but after some time it comes back. I've read that it's an specific issue with Galaxy smartphones. Anyone with the same problem? I want to know if there is a possible solution or if there's no solution at all.
Sorry if duplicated post.
I have a 128gb Samsung SD card.

probably a bad card. replace it and enable sd card encryption. that way the system can at least detect it.

The system has no problems detecting it. Some people was talking about this too in other forums. Going to replace it and test what you say.

Hi
I have a similar isues with multiple Note 4 's please see my thread , i hope it helps
http://forum.xda-developers.com/note-4/help/please-help-strange-problem-t3030198

I found the possible solution for Note 4 SDcard Issue after dealing so much with it, posting here it may help some people.
History :
If you own an SDXC or 64GB+ SD card with exfat you probably faced suddenly disappearing all the sd card contents where says the sd card is empty, mine started with this and formatting it using Windows, Note 4 and etc goes to same scenario, it actually happens because Note 4 and Windows formatting them using exfat FS.
In this guide you need a windows PC or TWRP or Mac at your choice.
Steps to fix the issue :
I assume only high speed sd cards (SDXC and U1+) with exfat larger than 32gb are problematic with note 4 and smaller size than 64gb can be formatted to Fat32 without any tools already in Windows, so this guide is intended for high end ones, like the one i had Silicon Power SDXC U1 Elite class 10
Metod 1: (recommended)
1. Detach your MicroSD card (most known to be problematic typr sd is SDXC)
2. Insert it to SD Adapter place to your laptop (if your computer has no dedicated sd slot attached to motherboard better use a laptop otherwise use Card reader) and remember drive letter
3. Store your sd content to your pc to restore later.
4. Download EaseUS partition master (free or other type) all will do the job
5. Right click on the right drive letter corresponding for your SD Card and select Format
6. Give it a name Like "SDcard" or what you like then select Fat32 for file system, finally select 64kb for cluster size, and press OK button
7. Finally press the apply button in top left and magic happens
8. Now you can place back your files, your sd card is ready.
Method 2 TWRP
1. Backup your data in an OTG drive or Internal storage or cloud.
2. Boot into the TWRP select wipe menu
3. Push advanced wipe, select MicroSD card, push change File System button.
4. In this menu choose Fat and press the button, wait for it till the a message says successful appear.
5. Now boot to your system and you'll notice it's fixed and you can place your files back.
Method 3 Using Mac OS X:
If you own a Macbook or iMac or anything similar just attach your SD card to it using its Adapter then run the "Disk Utility" app in others folder or type it in Spotlight (don't forget to take a backup already) then Select erase button on the sd card and use Fat in the menu, just you need to do it Twice, then you'll good to go.
I was able to do that in Sierra with latest updates.
If you find this article helpful don't forget to press thanks button or send me some good and positive energy

128GB MicroSD card - Disappearing files/folders

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.

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.
