[Q] Flashed to CM10M1 now having SD problems

I just flashed to CM10M1 and it now tells me that my SD is damaged. I have tried to format it using the phone but the unmounting seems to be taking really long. I have already tried formatting it on my PC, which works, as well as transferring files over, which also works, but when I put it into my phone i comes up with the same error. It is a SanDisk 64GB Mobile Ultra MicroSDXC Class 10. Any help?

I've heard some people had a problem after flashing CM10 with backups done with ROM manager. They said deleting the backups solved it, which doesn't really make sense if you've already formatted the card on your computer, but maybe it'll lead you in the right direction.

What format are you running? I think it has a problem with exFAT format.

Running exfat, will try reformatting to NTFS and will get back to you

How exactly do you do that?

I figured out how to format but it just tell me now that it is ready to be removed. Does it have to be in exFAT or NTFS when I format it

Try FAT32. It worked for me. It does say ready to be removed in your storage settings but you should also be able to see the external SD card. Use Solid Explorer and see if you can see the external SD.

TWRP microSD problems

Hey guys, I did a quick search and couldn't find an answer. Basically, I'm having trouble with TWRP -- it won't mount/recognize my SD card at all. All the advice I've seen so far is to format the microSD card as fat32. Unfortunately, this fix doesn't work for me, as my SD is already formatted to fat32.
Are there any other alternate options?
Thanks!
EDIT: this is on TWRP 2.3.2.3

you probably need to update TWRP. If you rooted using the Galaxy Note 2 tool kit, it's a slightly older version. Here's the thread on TWRP, which you can find the latest version.

I think i'm on the newest version. I updated it a couple days ago using goo manager to 2.3.2.3, which seems to be the newest one

that would be the newest. I had that problem till I updated. My SDXC card is formatted in NTSF. Maybe, you need to reformat it in your phone.

yea, I'll try that. wish me luck

Strange I threw my brand new 64gb in and it recognize it. Showed 59.45gb. I still formatted it and showed 59.47 now

That's about right for available space you'll get. But can you mount or browse the card in twrp?

I'll check in a little bit phone is dead and cycling battery. But my 32gb showed up. Are you sure you're not changing it to show external storage
Sent from my Nexus S 4G using xda premium

you need to go into advance menu, file manager. Then you need to look externalSDCard directory or similar name. That's your SDXC card. Don't use that external/internal option in one of the other menus.
This tends to be case in some of the file manager apps as well such as ES File Explorer.

ok, so, it seems it's not under external_sdcard, but under sdcard. So I guess to access the sdcard i have to go through that. Thanks for the help
Is there any way I can change the default backup location for TWRP to use the SD card? I can't backup to internal storage since I don't have enough space

I had a similar issue with this 2 days ago. ..Could not mount the 64gig sd card in trwp but works fine on the phone. ..I updated to the newest twrp yesterday and that resolve the issue. ..

I don't understand your problem when you go to twrp click install, you have the option to check to either internal or external right at the top.

This internal/external partition card storage is kinda hidden in plain sight...presuming the OP's SD card isn't toast.

Hidden in plain sight, really not that hard to see lol. If you can't take the 3 seconds to look where it says internal or external you shouldn't even bother trying to worry about it simple as that.

Tapping on "use external SD" just has it snap back to "use internal storage" and the error message "unable to mount '/external_sdcard'" comes up. So no, it's not that I'm blind.

MicroSD card losing connection with phone = MTP issues on JB 4.1.1 official release

Every time I flash anything based on the official JB 4.1.1 release, my 32GB MicroSD card (Patriot brand?) freaks out. The phone will say it's "unexpectedly removed" and then adds it back in, and removes it, over and over.
It's happened on all three JB 4.1.1 ROM's I've tried.
I thought my MicroSD was going bad so I low-level formatted it in Windows (hated doing this) and still had trouble. But ONLY with the card in the phone. Windows usually liked the card just fine.
So what I did to resolve it was use Titanium Backup Pro to "freeze" the "MTP Application". After doing that, my MicroSD works great in the phone and AFAIK, I haven't lost any functionality. So I'm not sure what the "MTP Application" is or does, but so far.... so good.
This post is just a heads up to others, in case anyone else runs into this problem.
Or in case anyone wants to tell me WTF is wrong.

Ive had this issue as well twice. Both times I had to format the sd card in my pc and it will work fine for a while. Im curious to know if you are using es file explorer? Im thinking it might have something to do with this issue.

Hmm come to think of it I just recently purchased root explorer about the time all this started but surely an app couldn't cause this issue? Heck I dont know it happens so random it hard to pinpoint the problem thats causing it. If I figure it out I will let you know

Ive been trying to duplicate the problem all day with no success. However I have froze the MTP app so maybe thats what the cause is? Would you happen to be using a sandisk micro sd? Because I am..
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2

Ahh hah I duplicated the problem on my phone anyway. I used the my file app to move a rather large file from the internal sd to my external sd and afterwards it lost connection. I had to remove the sd card and install it several times to get it to mount back again. Im not sure if its the moving of the file or the my files app itself that is doing it. I also noticed the media scanner isnt running after moving the file. So I hadnt pinpointed the exact cause but im dang sure getting closer. And I dont think its a bad sd card because I tried another and it did it with it too
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2

You were able to duplicate it even with MTP frozen?
Wow, I have yet to recreate the issue with MTP frozen.
My SD is a Patriot brand. Purchased at Fry's Electronics.

Yea it happened with MTP frozen and unfrozen. Ive tried freezing the my files app and every file explorer on my phone. I just cant put my finger on the cause it happens so random. But it seems me and you are the only ones having this issue so im wondering if we didnt get a bad flash when we updated. When I updated via kies it did not do a full wipe update it did what is known as a dirty flash which I never do because you end up with issues like this. So if we continue to ask each other questions we will eventually figure out what the common link as far as if its an app we are using and things like that.
So did you update via kies or odin?
If you updated via odin where did you get your firmware file file from and if you used odin was it odin on the pc or mobile odin?
And was your update a full or a dirty flash?
We are gonna figure this thing out one day lol.....
Edit.... well apparently we are not the only ones having this issue. Over on droid forums there are several s3'owners most on t mobile but anyway it appears there are a few phones out there with this problem and the only fix is to replace the phone and sd card because the phone ruins the card by unmounting it without stopping it first. My phone is still under warranty so I will be calling ATT tomorrow for them to replace my phone and throw a fit for them to replace my micro sd. I paid 48 bucks for this card and I think ATT should replace it since their faulty phone ruined the card

Wow.
I had the problem with two or three different ROM flashes. So it wasn't just one ROM flash.
Each time, freezing MTP Application has resolved the issue for me.
I'm going on ~4 days now with my current ROM and no more issues since freezing MTP.
Maybe there are a couple different SD card related issues out there.

I had the same problem with ADATA and Kingston brand sd cards. I tried the Sandisk 8GB from my old phone and no problems so far.

Freezing the mtp app has seemed to slow it down. The only problem with freezing mtp is that is how the phone mounts to the pc. Mine just did it again but I unfroze mtp to hook my phone to the pc and right after I backed some stuff up and unplugged it, before I could freeze mtp again it unmounted the card. Ive also tried several different sd cards and several different sizes even tried a 2gb Samsung card with the same results. Im thinking hard about going back to ics to see if that will resolve the issue. ...

I found that my 64GB card was not recognized by the newer kernels - when I use the older kernels or stock, it is recognized, otherwise, the ROM attempts to read the card, and then states it is 'ready to be removed'.

Try reformatting the 64gb card to a fat 32 file system. 64gb cards come formatted exfat and some s3's have had trouble reading them. Put it in a pc into the card reader and open my computer. Then right click on the drive thats showing your card. Ex drive E or F. Mine is drive N. Once you right click on it click format and a box will pop up and you will see the box that says exfat. Click the drop down box and change it to fat32 then click format and your done. Once it finishes put it in your phone and it should recognize it...

Well my 64gb micro sd came today from Amazon and from what ive read on xda and the net I would need to change the file system from exfat to fat32. So I put it in the pc pull up mini tools partition wizard and it gives me no option to format it, I try windows no option for fat32 only ntfs or exfat so I try a couple of others with the same results. Then I try hp format tool and finally format it to fat32 then put it in my phone and it says its damaged and needs formatting so I do and put it back in the pc and im back to exfat. So it seems to only work in my phone in the exfat format soooo im just gonna leave it alone. Oh I even tried formatting it in command prompt and changing the file format and it fails so now im starting to wonder if thats what happened to my old 32gb card and why I suddenly starting having trouble out of it when I updated to jb is because it was fat32. Maybe this new jb dont handle fat32 well or maybe my s3 dont like fat32. Hell I guess its just a mystery. ....
So I would suggest if your having sd issues try formatting your card to exfat and see if that helps the connection issues

Problem with new 64gb SD Card

Hi All
i have just purchased a 64gb microSDXC memory card driect from Amazon, to replace my 32gb card that was full, here is my problem, i have copied the contents of my old card onto my pc, put the new card into the phone and formatted it. then took it out and placed it into the pc, copied the files from the pc to the phone.
But when i put the new card in the phone and power it up, the phone starts up then i get the symbol of the sd card in the top left saying its checking it for errors, then the phone freezes up, loads of messages come up about things stopped working like settings, internet & other apps.
the phone then goes into a kind of reboot and then comes back on but then freezes again!
i have put the card into the pc and run check disk but no errors were found?
Please can someone help me with this, otherwise i wasted my money.
I am rooted and also running directory bind.
Thanks
Pete

[Q] Fail to download and or write to SD.

I have scandisk class 10 SD card 64 GB.
its formatted using the note 8 device (exFAT).
Whenever I try to download a file or copy a file in note 8 to the SD. It fails and reboots my device. knowing that reading from the SD is perfect. I can play music and movies from SD with no issues.
the only way I can transfer files to the SD if I connect the SD to the PC directly.
I am not sure if this is an issue with Note 8 or SD. please help!

Mine does the same thing. Ive tried formatting in exfat and fat32, didnt help. It writes fine to an old 16gb class 4 card ive got but not the 64gb. Sucks but at least it reads fine

I'm afraid nothing beyond painfully obvious ones - trying with another similar card, trying the card on any other device supporting exfat (if ok, this would provide definitive proof that card is ok), trying on freshly installed latest ROM, trying with the same card formatted in fat32.

It seems like this is the last resort. I will reformat my note 8 and try again. I also forgot to mention, that few weeks ago I was able to transfer one 800 mb file but this stopped happening. So it seems like there is not enough memory to transfer although I tried clearing the memory.
I will let you know if this reformatting the note 8 will fix the problem.
