I've been rooted for a while without any issues, until recently I'm not sure what happened but suddenly TWRP won't show the /mnt folder or be able to access anything on my SD Card, I've tried mounting and selecting the SD Card in TWRP settings but it displays 0MB and won't select it. All I see is my Internal Storage files, which means I can't flash anything easily. I don't know when it happened but it was working about a week ago. I formatted my SD Card as ext4 in TWRP itself and also tried NTFS on Windows.
NOTE: I can view the SD Card in Solid Explorer and on my computer, TWRP is the only one that can't mount/read any SD Card files or even recognize it.
Is there any way I can work around this without formatting the SD Card?

As the tittle says, my external SD card will no longer mount to my computer. The internal mounts just fine. I can see the external using a file explorer when USB mass storage isn't connected. I use my external card as a "thumbdrive" constantly and it has always mounted just fine, this just cropped up today.
I am running Bionix2 if that makes a difference.
What can I try to get it mounting properly again?
UPDATE:
I have tried turning on and off USB debugging
I have tried pulling the SD card, booting, turning back off, reinserting the SD card and booting again.
I have tried uninstalling the LG driver from the computer and reinstalling it (ADB)
None of these have worked.
The empty drive shows up in "computer" as a drive, the SD card just never mounts to it. When USB mass storage is ON the SD card definitely unmounts from the phone.
This is very frustrating as I need some files off the card and I don't have access to a micro SD card reader.
UPDATE2:
Got the files I needed by copying them from the external card to the internal card, connecting, mounting and copying them from the internal card to my computer. It is still a PITA though not as urgent as it was.
So last night I pulled the SD card, copied everything off and formatted it on my computer, didn't change a thing. I was then going to reload the ROM I am using. This didn't work as I am running external CWM recovery and it wouldn't mount the SD card either.
As a last effort before trying another card, I formatted (erase=format?) the card through Android. Everything seems to work fine again. I copied everything back to the SD card without an issue. CWM sees it again as well.
What could have caused the card to spontaneously need to be reformatted through Android after working perfectly well for 2 months?

I had the same issue, I think when you install different roms some use different ext for the drives, thats why its critical that after each rom you wipe wipe wipe, and as we know now, lol format sd card

Hello. I was preparing for a full wipe of my phone (Galaxy S3 i9300) for a clean flash for my next ROM. So I did was I got a SD Card Reader and plugged my SD Card in and put it in a laptop to copy the files, while suddenly, my SD Card got corrupted. I tried to format the SD Card with the same SD Card Reader (not knowing the Card Reader was faulty) but it made things worse. So, I took a different Card Reader, and formatted the SD Card and now all seems well. Until, when I put the .ZIP file in the SD Card, put the SD Card on my phone, and install .ZIP from SD Card on my phone using TWRP (2.8.6.1), it displays the error "E: Zip file is corrupt!" So naturally, I restarted the phone into recovery, formatted the SD Card using TWRP, changed the file system to FAT (vfat) and it displays the error "E: Unknown MTP message type: 1", then I tried repairing the file system, and it was successful. So I did was put the .ZIP in the SD Card again and try it again, with no luck.
I have already used all of these to format the SD Card and the phone still thinks the .ZIP file from the SD Card is corrupted:
Diskpart
Chkdsk
EaseUs Master Partition
Windows Format
SD Formatter (v4.0)
---------------------------------------
TL;DR
Phone got fully wiped, SD Card got corrupted while transfering files because of faulty Card Reader, SD Card got formatted a lot of times, Finally got the SD Card running, but now, if I put it inside the phone, it thinks the .ZIP File from the SD Card is corrupted.
What should I do?
p.s. (I already downloaded the same .ZIP file multiple times to make sure it was healthy, and it is)

Yes, the .zip file does work. I can open it on my pc
Sadly, I can't get a new SD Card. Mainly because I need this SD Card because it is a 32GB SDHC Class 10 SanDisk SD Card, and it's not cheap to get a new replacement (of the same SD Card).
I would like to know how to fix this corrupted SD Card. Because everytime I plug it into my PC (and use Windows Check Drive for Errors, and Chkdsk) and find there's no errors. And then when I finished placing the files into the SD Card, when I plug it the next time, everything got corrupted, but Windows still does not detect any errors on the drive..... wut

Copy paste via USB cable? The ZIP might be corrupted in a way that the script is broken or somehing. Try copypasting the file via USB and if that doesn't work download a different ZIP.

Thanks for all the help. I was in contact with SanDisk and they are willing to replace the corrupted microSD Card. Anyways, thank you
Hi,
since the internal storage of my 8GB Moto G3 is pretty small, I wanted to move apps to my external SD, but there is only a hand full of apps I can move.
So now I wanted to partition the external SD I have, but when I want to start the partitioning, it says "E: Unable to locate device to partition".
When I google for exactly this error message, I can't find any solution. I formatted the SD via the phone, I also formatted it via PC to FAT32 and exFAT and I formatted it via TWRP to exFAT and also to EXT3 and EXT4, none of these methods worked.
I also tried it with the MicroSD mounted and unmounted, made no difference.
Also can I make the external SD to the main storage for the phone, so all apps put their files on the SD card like Whatsapp, without symlinking every folder manually?
All apps won't move to the SD. I'm guessing that if the developer specifies internal, that's all you get. On the first soak you could force apps to external which I tried with mixed results. A few would work, some wouldn't. Even on the latest, some app's widgets won't work if the app is on external.

Having the same issue here, I have a brand new Santin 128gb and I want to partition it to my HTC One M9, I formatted it and then wanted to immediately partition it and then I am receiving the same error and cannot find anything else online.
Same problem here I've got a Lexar 32 GB Micro SD.
Same problem here, with twrp 2.8.2.0
Hi everybody,
I installed CM13 ported for my Alcatel Pixi 4 (5) 5010.
Everything works fine, excepting the camera and the external SD Card. But the camera doesn't count so much. I want to make my phone detect and use the SD Card. There is a file mmcblk1, wich I think is kinda connected with the card. If I use apps like Aparted, Parted4Android and Mount2SD the SD card is founded. But wathever option I select(mount, delete, format, create) still no SD Card directory created. Is there something I can do?
The SD Card is detected by other devices. I also formated it in NTSF, FAT32, FAT16, ext4, ext3 and still no resolved. But it is founded in TWRP Recovery.
Thanks.
PS: I also installed other ROMS and all detected the card. But this is the only one having root. (Can't root this phone, not even by flashing zip files.)
hey guys i kinda screwed something up, i was going to swap from using my sd card internal storage to portable so i backed up the data folder and the obb folder, then i formatted the sd card to portable storage and then i realised that there was no where near enough space for all my apps and i found out you cant move them to the sd card so i switched the sd card back to internal storage.
so formatted the sd card but now when i use es file explorer ti says the the card cannot be found so i cant set thing back to how they were?
any idea how to get the sd card to work as it did?
What format is your SD card? You may have formatted it wrong.

i just checked and my sd card is formatted to f2fs mate but it is working now somehow
You optionally need twrp with f2fs support, you can find it on xda, not on twrp.me. @robgee789
I think you need only twrp:
