Corrupt Sd Card - MTCD Android Head Units Q&A

I'm having trouble with my sd card becoming corrupted, 2 or 3 times a day , I'm
only using to play music , I've no idea whats causing it (does it only happen to me)
the only way round it afaik , is to unmount sd card everytime I'm shutting down but that seems a bit extreme

Have you tried with another card?

32gb transcend and 16gb sandisk , same thing,
I cant format it in the system either , It says corrupt sd card and asks me to format , so I format it ,choose to use it as portable storage, when it finishes it starts checking for errors and always comes back as corrupt again , I have to format it in laptop and even then sometimes I have to do it 2 or 3 times
before unit recognises it as not being corrupt

Out of curiosity, what unit do you have (manufacturer)

Its a Erisin , model number A-MEDIA AUTO (1024x600 W)

No it is not. Erisin is the seller. Check what is after MTCD in the about screen. Kgl? Ksp? Etc. This is the manufacturer. I bet you it is a KGL

Yes its KGL v2.54_4 , and ES6700F but cant find that anywhere on unit

Kgl units are garbage. I returned mine with similar symptoms it killed an SD-card. Then it refused to recognize any other SD card.

To late for me now, I've put a custom rom on it,
it actually works ok except for the sd card issue , guess I'll just have to get used to
unmounting sd card before switching off

What does installing a custom rom have to do with your warranty.. just return it and ask for your money back

Strange problem, then... I have a KGL PX5 unit too and - so far... - the SD card is working good.
I'm using the 8 Gb card that came with HU (with GPS maps on it), so I suppose it's not even the best quality one... and never formatted it.

I am having the same issue with my Xtrons PA7739BP..It's a MTCD_GS
Already tried 2 different SD cards. And both give me the same result. Need to format, but after that still not able to use it.
First SD is unknown brand, second one 32gb Sandisk

If you want to format it because it seems corrupted (and cant do it in any way as you told) then it is broken and you need to change it at service.
I had also my 16G microSD changed
is it a branded card?
exactly WHY cant you format it?... wanna give us some insight into what happens?
I couldn't format a card with a number of programs - In the end I tried 'Flash Format' by CNetX (google it) - it worked first time on the free evaluation version.
Good luck.

[Q] sd card not detected anywhere

Hi,
I have a samsung galaxy note 2 and i bought a cheap micro sd card from ebay which was a big mistake. the card is 64 gb and i bought it a month ago. it was working fine until yesterday. i got a notification saying safe to remove sd card.i went into storage settings and it says mount sd card. when i mounted it,i got another notification saying blank card and then it asks to format the card. i took the card out and did the same procedure several times but the same thing. i've got important data on the card and have no other backup. i also used the usb cable to connect it to the computer but it only recognizes the phone memory and not the card. i dont have a card reader. i have checked several threads here on xda but i cant find anything related to my problem. please help me....please its really important. thanks.

[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?

corrupted sd card but PC sees it just fine

So, about the problem. All was fine untill a few hours ago. My note 10 notified me that my SD card is corrupted. OK, no biggie, lets just take it out and put it back in. Worked before, but not today.
Tried the same SD card in my laptop, worked without any problem. I'm feeling trolled. Next i tried with otg sd card adapter. It says "no supported partition was found".
Next, tried another SD card, still nothing. Tried that one with otg - bam, works. So, it's not card that's bad. Tried another one, was empty so i formatted it on phone. Nope - still corrupted. No matter how many times i formatted it, it's always corrupted.
But it works on laptop. All 3 of them work on laptop. Two of them i can see with otg, the one that was all the time in the phone says no supported partition.
Then i thought, maybe the sd reader in phone broke. Rebooted to recovery and guess what? First SD card that showed corrupted message works just fine in recovery. Now, one reset to factory setting would probably solve the problem but i have tons of apps that i'd need to backup and no space to do it because my sd card ain't showing in OS.
All i wanna know is am i doomed to reseting android or is there any trick i could use to avoid that?
Copy all things on your pc,format the SD Card in the Phone and copy all Things back to SD Card
nope, didn't work. had to reflash OS
