[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.

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

internal sd card wont mount

I was going to post this in the AOKP rom page but i figured it'd get seen more here and maybe its not even a problem related to the rom. I recently installed the AOKP rom located here http://forum.xda-developers.com/showthread.php?t=1831858. everything was great the first day then i started getting random reboots and losing my data. So I flashed a back up and still got the same problems. I lost my data yesterday, fixed that by manually changing the APN settings and everything was fine other than still getting random reboots. today I went to take a picture and it says "no external storage". I opened root explorer and I can access my EXTERNAL SD card but not the INTERNAL. I tried to mount in via the setting, storage menu and it wont mount. Also tried mounting in CWM recovery, no dice.
Is this a hardware problem or something software related? Anyway to get my stuff back or is it gone? I thought about trying to format it through recovery but how can I do that if it wont mount? Any help would be greatly appreciated.
I'm about to go through and install a "clean" copy of this ROM hopefully. Or I might try another ROM I know works like it should.

Installed a new Rom. Everything works perfect so far but still can't access my internal sd card. Any tricks how to get this back or do I need to just turn it in for warranty?

Warranty may be your best solution, you'll have to revert to stock using kies/odin which may on it's own fix your issue.

Are you also receiving the "Blank USB storage or has unsupported file system" error?
I have been battling this issue for a friend of mine (I own only the I9300) and I believe I have somewhat of a fix. It will allow you to use an external SD card.
If you can use / access the external SD card on your phone then disregard this message.
If you can't access any of the storage, including the external SD card try following this short tutorial I made:

Im still able to use my external sd card. I can read and write to it from both phone and pc.

The internal SD card is essentially part of the motherboard. If it's corrupted, you have no choice but to warranty the phone out. Kishke's right in that restoring to stock might be your last, best chance.

[Q] need mnt/sdcard/<files>

i lost my mnt/sdcard/<files> i delete them oh what a mistake!
but they were useless .
they story was began from 1 day i decided format my internal sd card then i did it from >setting/sd car and phone storage/format internal storage.
at this time i had 2.2 froyo . i tried flash 2.3.6 GB ,scan sd card for viruses , format ex sdcard.
but when i did the last thing (format ex sd card from>setting/sd card and phone storage/fromat ex sd )i lost my ex sd card too (must mention it i did format 3 time internal sd card and 5 time ex sd card again and again cuz i had sd card removed unexpectedly issue and somewhere said it happen by virus (i guess true cuz i downloaded some app recently and after that the sd card removed unexpectedly was occur)but those formats clear all thing. phone doesnt recognize both sd cards even .
now i live with a 4 gb ex sd card and unavailable int/ex sd card. (yea its unavalable but when i put it off without 4 gb ex sd the phone wont boot up)
in my phone i just see system root (no sd card no internal memory) .
the one thing i am thinkin about that is .maybe should i have this directory files backup mnt/sdcard/<files> .maybe if i copy & paste those files again my sd card come back again .maybe .cuz i have no doubt it mnt/sdcard/files wont change after flash official rom.and i cant flash a custom rom jelly bean (i hear that directory is /sdcardo )till phone cant recognize ex sd card.
i have no other idea.
so plz upload these files mnt/sdcard/<files>

[Completed] system unmount edited

Hell everyone I'm not a tech but just an Android user with a broblem. OK, I own an ainol numy 3g Chinese version. It came with 1gb ROM, 4gb Ram storage space, I also install a 16 gb SD card in there. My problem is that, every thing I down load apps or data it goes to a 1 GB internal memory storage. And the 4gig storage is there untouched and the phone doesn't give you an option as to where to choos to store your data.
However the sd card was being recognised but the system was not automatically using it. I had to manually coppy data to it. All of a sudden the system unmounted the sdcard. It would no longer see the SD card.
So I decide to root the phone and install Root explore to check if I can detect the sauce of the problem.
First thing was I try to write to vold.fstab and Rexp reported that the system is not mounted. Same thing for the 4gig storage and the sd card. So I downloaded adb tool.
When I try to check for my system adb reported that the system is un available. Go back to root explorer it reported that my USB is not mounted. Can any one help me to solve this problem. Thanks in advance.

Broken storage and /boot missing (or unmounted)

Hi,
so I have a really weird issue with my Redmi 6. As you've read from the title my phone's storage is broken and /boot is missing (or maybe unmounted).
Let me explain what happened.
So my bro needed 16 GB SD card for postmarketos (the SD card was in my phone) so I told him that he could have it. He had 4 GB SD card which wasn't enough for the postmarketos so he gave me the SD card. When I inserted it to my phone, MIUI asked me what to do with it. There were 2 options. Use it as external storage or extend internal storage so I selected extend internal storage. When the process was done, internal storage was unmounted... I tried mount /sdcard but it didn't work. Then I came across a video that has sm command in it and it was a partition management command or whatever. So I tried mounting internal storage, and it worked! BUT when I opened file manager it detected internal storage as USB. I literally have NO idea why (MIUI file manager detects it as USB but Google file manager detects it normally). I tried to fix it with the sm command, but I only made it worse... When I tried mixing the partitions I accidentally typed disks instead is disk (sm partition mixed disk"s":128,179 50). Then I think is started formating the partitions. I was lucky enough to cancel it, before it formats the whole /. It formated only the SD card and I think /boot. I don't think I can give any more info about what is did. I hope someone could help me.
Thanks for your time.

PS I don't have my phone rooted or unlocked bootloader or a custom ROM

Note: Everything happened when the phone was on

Please someone tell me a fix
I'm waiting almost a month and so far, no answer

Thanks
