Problems Formatting SD Card/Working In Phone

I seem to be having problems formatting my Sandisk 64GB MicroSDXC (Class 10) card in FAT32 & having it work in my AT&T Galaxy S3. The card comes preformatted in exFAT, and it works in the phone just fine that way. But, I heard it's best to format it in FAT32 due to some issues I saw about some people having some of their music files not show-up (if they have a rather large music collection, which I do - 85GB's worth!) in whatever music playing program they're using, so I'm attempting to format it with FAT32 to avoid that. Now, Windows 7 (x64) does NOT allow you to format drives via FAT32 (unless you go into DOS), so I've used a couple of different programs (Fast32Format, EASEUS PartiionMaster); I got a message on my Galaxy S3 saying my SD card was damaged or missing when I used Fast32Format); a bunch of services stopped working on the phone when I formatted it using EASEUS PartionMagic, and I even tried formatting it in NTFS (which I think that Android doesn't support) & got a message my SD card was blank and Android wouldn't even mount it!
What am I doing wrong? How can I format it in FAT32 and have it work in my Galaxy S3?!! Do I even really need to use FAT32 instead of exFAT?
Thanks,
Dennis

EaseUS worked fine for me - the one thing that screwed me up the first time is when you tell it to format it, you also have to tell it to apply it. And hopefully the "Fast32" was autocorrect - you should just be using FAT32 - and I don't think I changed the block size. HTH

I apologize for bringing up this old-ish thread, but I always see that every time someone makes a new thread, they get bombarded with "use the search feature", so uhh, I did .
I've got a Class 10 SanDisk Ultra 64GB MicroSD XC card, that refuses to work with my Galaxy S3. I've got CM10 on it, do you think that might be the issue? If so, how do you think I can rectify it (what format would work?)
I've used EaseUS to delete the partition, and recreate using FAT32, but no dice, still getting a "damaged card" notification. I can seemingly use the card fine on my PC and my Mac, but nothing on the phone.
Any help would be greatly greatly appreciated

Well, this is ominous given that I ordered this micoSD and it just shipped. I read lots of reviews on Amazon and those with S3 phones seemed to have no issues using card as is, although they didn't specify precisely which version of S3 they had. The S3 natively supports 64 GB, so I would think it would work out of the box, so to speak. A number of reviewers said they used this microSD in older phones that supposedly supported only up to 32 GB. They formatted in phone, getting something like 59 GB of usable space.
I'm using stock ROM with CWM on I747.

A more complete response...its a known issue with AOSP based JB ROM's. This is pulled from the AOKP FAQ, since it is an AOSP based ROM as well this should help you out.
Will my 64 gb sd card work? Except it works fine with a 64GB card. http://rootzwiki.com/topic/28124-doe...card-standard/ The SGSIII is the first phone to support exfatl, but the support is Kernel based, some people are having trouble with the replacement kernels and exfat support. The solution is to force it to format in FAT32. http://www.online-tech-tips.com/comp...ive-to-fat-32/ I know, because I've done it. --- Don't respond without actually doing research. I have no problem spoon feeding information, especially when the information you put out there can increase misinformation. The SGSII also supports a 64GB card as well. http://androidforums.com/samsung-gal...ing-sgsii.html naturefreak85l;
EDIT - Apparently the links are dead, but there a many methods to choose from to format and SD in FAT32.

Card problem

Hello, I'm new to the forums.
Today I bought a 32 GB MicroSDHC memory card for my at&t s3.
Behaviours:
1) I inserted it into my phone and then I tried taking some photos. I set the output path to the card and I took a picture. The picture was successfully saved to the sd card, but when I tried taking a second picture, I received an error: "Cannot write file in SD card. Default storage set to Phone". If I try again to set the memory card as default storage I can again take another photo, but the next one will fail as described again.
2) With SD card mounted to the S3, I plug in the USB to connect it to my computer. I can then see the card and view the files on it. However, I'm unable to write anything on it. (Copying something to the card will freeze my windows explorer)
3) If I insert the card into my computer via adapter, then all works fine. I can write to it fine.
It seems that the problem only occurs when the sd card is used by the S3.
Note: I have checked the card for read-only notches and it has no such thing.
Note2: I have a rooted phone running JB 4.1.1 stock.
Any help will be appreciated. Thank you.

Maybe you can try reformatting it.

reformat it in what way? I've already tried exFat, Fat32 and NTFS. NTFS and exFat give a "blank card" error, while Fat32 won't let me write stuff like I described. And I've reformat the card a couple of times already.
Edit: well, I did so using windows format app.
Do you know of other better apps?
Also I forgot to mention that I can't format the card via samsung s3 built-in app because it always returns "blank error" in that case.

I also had a problem with a new card and I took mine out and put it back in the phone and it finally worked. I just made sure it was pushed in all the way and seated properly.

I have just tried to use the card on a Galaxy S Plus. It worked flawlessly. I format it from that phone and then I inserted it into the Galaxy S3. It still won't work on the S3.
Why is this? I'm becoming desperate. This issue is bugging me a lot. Please any help will be appreciated.
Update: Even tried a galaxy S2. It works fine. Same problem on S3 though.

[Q] MicroSD Question/issue

I have the Tab pro 12.2 KK4.4.2 and purchased a patriot Micro SDXC 64 GB. My question is similar to other posts and I will try the posted solutions when someone can confirm the validity of the SDcard. Samsung specs for the Tab(SM-T900) state support for micro SDHC up to 64 GB. All of the reading I have done shows that the largest SDHC cards is 32GB and anything larger is a SDXC. So is my64GB SDXC card actually supported in my device? I have not been able to write MP3 files from my PC to the card or any other files with any success. Put I am able to do it fine on a smaller 16GB SDHC card. Can this version SM-T900ZKAXAC be rooted?
Thanks

I contacted Samsung and they are going to escalate the issue up the chain. It seems as though the tablet only supports Fat32 file system, while SDXC cards are only can only be formatted using exFat or NTFS. That being said I tried formatting my card with NTFS in hopes it might allow Fat32 after but it wouldn't format using NTFS.
Is no one else having this issue, as I have not seen 1 other post regarding this particular problem?

Mossey, do you happen to have a Windows computer?
plug the sd into a different phone if you can and connect as external. Click Start->My computer->right click and format to Fat32. I do this all the time

I thought for second you had the solution. I have another tablet and tried reformatting using it. I had the stick showing fat32 file system but it was 32gb vs 64gb. But the tablet recognized it initially, so l reformatted using the tab, but now the tablet looses the sd after it writes a few files to sd. Then if I try to view files on the tab, I get a message that the ext sd card may not be readable.

Hm interesting, it seems like it might be a permissions issue.
Can you try doing this on a device that runs something before 4.4.2? Kitkat is known to cause lots of problems with SDcards
hope you find the solution.

Again- Thanks. I thought it odd as well and it didn't add up. Although the SD card was working OK in my new Sony camera I decided to return it to C.C. for an exchange, voila problem solved. This still tells me that Samsung Technical support is useless. Everyone spent a lot of time trying to solve this issue. I still am finding odd things happening with Kies but I have found some work a rounds.

64gb micro SD problems

I'm running Jasminerom 4.0 and I cannot get 64gb micro sd cards to work properly on my VS985. If I format via settings, it defaults to exfat. Performance suffers and I seem to get random corruption of files. I've tried formatting to fat32 via TWRP and via Windows. Performance is better for a bit, but in time the phone starts not writing to the card for some reason. I've tried 2 different cards, Samsung evo and SanDisk ultra. I'm currently using a 32gb SanDisk ultra which works as it should.
Any others have this problem with 64gb cards?

Yes i have this problem too. I somehow semi-repaired files corruption by formating the 64GB card with Easues partition manager. Format it with this program as FAT32 and see if it helps.

Thanks I'll try that and let you know how I make out.
Using a 32gb card is an ok workaround but this problem really bugs me. I'm hoping the lollipop update might fix this issue. We'll see...

Like mentioned above, formatting your card to 2x fat32 partitions should fix it. The problem is with exFAT. I doesn't see it as a removable memory and ends up getting corrupted, sometimes, a reboot will fix it but after a while, it needs a fresh format.
I'm thinking the problem is with the kernel as stock didn't give me issues, could be wrong though. I know CM broke it last week so ROM that are base off it would have it broken as well but could be fixed by now.

I used Easeus to format to fat32. The card worked great this weekend.
This morning I checked for some files and several entire directories had been deleted. Looks like I'm having the same issues as before, and I really don't know what is triggering it. I'll stick with my 32gb card for now.

has anyone found a solution for this I've bought several different top of the line cards, anything over 32gb stuff gets corrupt.
appreciate any help, thanks in advance

Asking for help with a micro sdxc 128gb problem

Hello this is the first time I'm posting here
I'm sorry if this has been asked before but I couldn't find any answer other than "xiaomi didn't fix it"
I bought a sandisk 128gb microsdxc after double checking that it could handle this amount (It's listed a having a max of 256gb) I tried it on my pc and it was golden until I tried to use it on my phone, it shows up and says it is a 128gb sd and lets me use it as a internal or external memory but that's about it, it can't read or write on it and my pc can't detect it when it is on my phone
I also noticed that it doesn't let me take screenshots without my other 16gb sdcard, it says there's not enough space for it even though I've just used 18gb and clearly have enough space
I'm curious if there's a fix like changing to a custom rom, flashing certain file or something like that
Thank you!
Edit: If I use it as external it lets me write and read but it doesn't work as I want it to, also if it's as external it doesn't let me take screenshots as I stated above

I advise trying other brands than Sandisk, if problems persists. There are some problems when using Sandisk SD Cards like sudden read-only SD card. I've tested other cards (Eaget, G.Skill, Gigastone, Samsung, Transcend) and they were better to me.
Also, SD cards should formatted to FAT32 if using it with this device, as Xiaomi did not implement exFAT support for this device. You can search how to format huge cards to FAT32 on Google.
Also, check if your card is genuine. If your card has huge CE stencil on the back, it is fake. Sandisk shouldn't have that mark; it should have serial number and Made In China/Taiwan on it.

I formatted it to fat32 and still no luck, it works with any device except my xiaomi so that's weird, I checked the back and it's genuine btw, I guess I'll just use it on my camera or as a usb, thank you anyways

Sorry bro but Xiaomi didn't fix it lol. I've had this issue constantly on Pie, but it worked OK in Oreo, maybe you downgrade or try another ROM?

same 4 me

Yeah, I agree. I have 2 MicroSD cards that being destroyed by Xiaomi stock ROM simply by self-ejecting itself numerous times, and also it lagged a lot because it always check for 'corruption' where their firmware causes it.
The simple solution that I took is to get a custom ROM and kernel installed on my device and since then, these MicroSD card problems were gone; hell even better that custom ROM / kernel can handle exFAT than that of Xiaomi AndroidOne.
