[Q] Can't mount SD card SGH-T989

Hi guys,
I tried to find solution but couldn't find. the solutions were for different phone and etc. so not sure if that would apply to my case this is why want to make sure will get right fix for the issue
Phone was working fine for a couple months but couple days ago I noticed that I can't take pictures because it can't mount sd card
Well I'm thinking I will restore from backup but guess what I can't because clockwork can't see the sd card so I'm kinda stuck here. I think this is a phone's internal memory card not the micro sd card. Am I right?
Thanks for help in advance and if there is a thread with same issue and device please send me a link as I couldn't find it.

not sure if this is enough info but if you need anything else please ask
thanks for help
Oh well today I had some free time so I sat down and tried to look for fix, turns out it is was external micro sd issue which failed.
Phone was setup to use external card. So after I told phone go and use internal memory rebooted and all good, inserted smaller micro sd card, just to have some additional memory and all is good. So here you go if you will have something similar going with your phone maybe that will help you.

how did you tell the phone to use internal memory? i'm running across this same problem where my external sd card is not being mounted or read

64GB micro sdxc "damaged", unable to format

So I've been looking around for help on this across various sites and I've had no luck fixing my problem.
I'm running the most recent CM10 nightlies, which I read might influence which formats the phone can read, and even after I formatted the card to FAT32 via the gui app and easeUS partition editor my phone still says my card is damaged. When I try to format it it just says "unmounting card" with the spinning circle and sits there, never unmounting and formatting like it wants to. I tried to mount/unmount and format in CWM, no dice. This card is brand new out of the package today so there's been no previous use or problems.
Am I just going to be unable to use this card while running CM10, would I have to go back to a TW ROM or stock to make it read correctly? It will show up on my computer when I plug it in and files transfer to it fine so I figure it's a problem on the phone's side. My old 16gb card from my DX works fine and that's what I'll use in the meantime but the space is dangerously low, hence why I jumped on this 64gb card when it was an Amazon deal.
If anyone has some insight or experience with this I'd really appreciate it, I'm guessing it's a problem with CM10 or I missed some tiny step somewhere but I've tried a lot and had no success.

What exactly is the partition editor you used, and why? The GUI program to format it to fat32 is sufficient...
I would guess either it's the card(what brand btw?) or the partition editor.

It's the "SanDisk Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s with Adapter SDSDQUA-064G-U46A", I've noticed a lot of GS3 owners have been buying something similar or the same.
I used EaseUS Partition Master as well as the fat32 gui program that's been circulating, sounds like you know the one, and while the format was successful the phone still sees the card as damaged and won't completely unmount the card when I try to format it like it says.

You try formatting it on a windows computer

That's there exact same card I got. Format it again with the gui but DON'T use the partition program. I guarantee that's what is messing you up.

Did you use the sd adapter to plug into the computer or you did it while it was inserted in the phone already? I did the latter, idk if buying an sd slot to usb would change anything.

I am having the same problem. I thought I had a bad card, so I sent it back. Now I am searching for a solution as well. I will give this a try later tonight.

I used the adapter and put it directly in my computer to format it.

Ah ok, looks like I'll have to buy an sd-usb plugin then.

Had the same issue on two different cards and eventually they said that they were an unsupported raw format. Called sandisk and they said there are a lot of issues with the 64gb class 10 cards and the SGSIII. I am on my third one. This one has been working almost perfectly. I often get a unmounting remounting issue with the card, but I am not blaming the card yet as ever since I flashed the cracked aboot I have been having odd issues. I am going to put my phone back to stock and start over here today or tomorrow.

I fixed it
I bought a multi-SD plug-in with USB, slid my card in there, ran the gui on the card, put the card back in my phone and it worked fine, the phone recognizes it. For whatever reason the card didn't want to format while it was in the phone despite my manipulations, so plugging the SD into the computer is crucial I think.
Thanks for the support guys.

I have done everything described here, and still have what the OP says. Card is not recognized, like its not even plugged in to the phone, is formatted as FAT32 and works in windows.

Well, I literally fought this for 3 hours, and finally I just deleted the entire partition and formatted the card in the stock ROM. Then I pulled the card and formatted with EaseUS partitioner as FAT32 and put it back in and it worked. Then I flashed back to CM10 and it still works.

How frustrating this is....

[Q] SD Card Not Writeable?

It seems that my SD card is not writable when inserted. Is this true? I tried to create a new folder on it with root explorer (I am not rooted though) and it said that my device needs to be rooted in order to accomplish that task.
Any ideas?
Jonn

Did you try something like es file explorer? I would try that.

That didn't work either. It says "operation failed".
I actually noticed that it wasn't working playing act raiser and it wasn't saving my position. Moving the ROM to internal storage worked. I then tried to create a folder.

Huh. Just tried a different SD card and that one worked. Weird.

I spoke too soon. After removing the sdcard that worked and putting it back in, it no longer is writeable.
Sent from my Nexus 7 using Tapatalk 2

It works again if I pull the card out, restart the shield and put the card back in. Perhaps something up with the mounting process?
It appears that once a card is mounted, if it is removed and re-inserted, it remounts as read only.

It looks like sdcard mounting is messed up. I can't get any of the sdcards i have tried to mount.

Did you go into settings and actually click unmount before removing the SD Card? Many linux systems (android is linux) will mount devices which werent safely removed in read only mode for some bizarre reason.

I tried that as well. It still doesn't work.

when you go to storage under settings, under sd card does it show total space for card. if not maybe you have to format it to NTFS first. thats what I had to do with my new card. also said to do so on shield guide

I did not read the destructions. The destructions have useful information? Where may i find these destructions? I assumed fat32 so that is what my sd is formatted to.

Yes, I formatted it to NTFS before I inserted it. It shows the total space and space available, it just doesn't allow anything to be written to it. I can take it out and put it in a PC and it works correctly. I also have another SD card that I tried and it worked for a few minutes, but I haven't been able to get it to keep working.

sorry I dont know what else to tell you, i first had the same problem like yall when I stuck in a brand new card. nothing I downloaded would go on to card. and it didnt show the amount of space left under the storage menu. Then i found out it need to be formated to NTFS. Once i did that everything started downloaded and showing up on card.

The only memory card I have gotten working (about 1 minute ago) is 512MB and formatted fat32
The card i want to us is a 16gb microsdhc formatted fat32 when this memory card is in my shield it knows it has a memory card but says it has no partitions on it.
I am running testdisk on the sd card and it found 9 partitoins. I will try and clean that up.

To be honest, I've never tried SD card support on the device. So I can't say one way or another. But I'll be looking at it soon enough since I got my first build of CWM for SHIELD waiting for me to debug in the other room once the kids go to bed.

I just tried two different 8GB class 10 transcend cards, an 8GB class 2 generic card and a 256mb sandisk card. I put each card in and copied a file from internal storage to it. Then I removed each of the cards without unmounting and put them back in and proceeded to copy a file to the card again. Every time it worked successfully. I do not even know what format they are in and didn't format them before testing. And, maybe the issue didn't show up because I didn't give it enough time. I am not sure.
Also, I know this is probably a really dumb question but the micro sd slot is spring loaded. You are pushing it in until you hear a good solid click right?

issues
Having issues of my own.
Bought a 64gb sandisk SDXC card for shield. It worked 100% fine in my SGS3 formated for exFat. But not in the shield...
It seems to work somewhat when formated for NTFS. But the file path is really messed up and 1/2 my apps cant see the SD card because of this. It something like (root/storage/sdcard1/....)
2 apps that are basically usless right now due to this are Power amp & FPse.

Android doesn't normally support either exFat or NTFS. The shield may include support for them but if I had a shield I would steer clear anyway and go with what android definitely trusts in FAT32.
Hopefully NVidia will do a firmware update to sort these problems though

[Lenovo A850] SD CARD PROBLEM

Okay so it is been some months that I am using this phone, there is actually no problem with the SD Cards that I have used in the past few months, I bought this new SD Card(that has problem) in the last 1.5 month/s it worked really well and no problem at all. But in the last 2 days, I restarted my phone(changing sim card) turned it back on, then it did not detect the SD Card, I have tried some things like formatting the phone but it did not fix it, I have tried inserting the SD Card into a card reader and insert in my computer it worked, it detected the SD Card, I then tried formatting it from the operating systems formatting tool, I also tried formatting it with SDFormatter V4.0 but it did not fix it. There was a day when my friend tried to edit voldf.stab file from /etc/ since I want it to be like the External Storage will be Internal and vice versa. That is all the informations I can give and is in my mind right now, you can ask more questions regarding this tho thank you so much for reading and I really need help in here. I cannot figure it out.​

My assumptions-
-Faulty SD cage (in case you accidentally slotting in SD card with force)
-Recent change in kernel (I really don't know about kernels, check the other thread)
-Pathogens....( I mean viruses, probably system level that bugs the interference from SD slot to system)
That's my guess. You may try to consult an experienced phone serviceman, or Lenovo Service Center (if your city have one).

Major issue formatting SD card

I got a new phone today (ZTE ZMAX Pro) and I took the SD card from my old phone and put it in my new one. I formatted it, unmounted it, and removed it properly. Whenever I try to format it as internal on my new phone, it sticks on 20% and comes up with the following error message: "java.util.concurrent.TimeoutException:Thread Binder_6 gave up waiting for partitionPrivate after 180000ms." I also got another one, the only difference being "Thread Binder_B."
So, I restarted it, and wouldn't you know it - it recognized the card. So, I formatted it for photo swapping or whatever it is, and it worked. I then tried formatting as internal, and it did the same thing I mentioned earlier. So, the card will work as usual after some restarts and removals, but is it pretty much screwed for internal formatting?
The card is a 64 GB SanDisk, and it works just fine on my computer.
EDIT: I just tried with a 16gb card, and it worked fine. I guess the question now is: is the 64 gb card able to be saved?
