My G6 Shows 'Corrupt SD Card' Error but Fails to Format it

[INeedTogepi]

My G6 says that my SD card is corrupted, so when I go to format it the percentage completed immediately shows 20% then, after about 10 seconds, the formatting screen closes before it completes the format, and the whole time it shows that it's formatting it is always at 20%. Then my G6 acts as though there isn't an SD card in the phone, it only shows up again after I power cycle the phone. I have tested multiple MicroSD cards on this G6 and the same thing happens for every single one I tested, but I happen to have (limited) access to my mom's G6 and when I tested the same cards on her phone it says the SD card is corrupted, but successfully formats it and mounts it.

The MicroSD card that I would like to use with my phone is a 200gb SanDisk card.

Thanks in advance.

Hey, Can it be read/formatted in a computer with your sd adapter like a flash drive? if it can try reformatting it there then see if your device can recognize it. if it can't or it says corrupt / needs to be formatted and craps out... it's your SD card. it is the same one I had (probably..with red lettering on it?) That's the bad news, the good news is you can still go online and register it with SanDisk and they will send you a new one for free (cost of shipping to them the corrupt one, you have to pay.) But they will send a replacement, I think it took about 2 weeks to get one back.
Take care.

I can plug it into a computer and format it successfully, it works in literally every other device that I've tested it in, including my mom's G6. That's why I have a feeling that the problem is being caused by some sort of issue with my G6. I have tried factory resetting my G6 two times already and it failed to fix the issue. I want to root my phone, but my software version is H87211h, and the method mentioned here has (as far as I know) only been tested on devices running H87211g.

Hello there. I have same problem with my LG G6, It shows every SD Card as corrupt and tap to fix. when i try to fix and format it get stuck on 20% its been more then two months and i am unable to use the memory card on it..
There is nothing wrong with Memory cards , it is the problem with the LG G6 either it is software issue or may be due to the fact that i have changed the Sim Tray as my sim tray was broken... The Network sim card work fine only problem is the Sd Card.... If any one have the sim issue or any solution .. Please share.. Thanks

Same thing happened to me, my SIM Tray broke and I bought a replacement from Amazon and that's when the issue appeared.

I updated my G6 to Oreo and now it shows what command is causing the formatting app to crash. I've attached a screenshot.

OK, so with the new info (sd tray breaking) I think what happens is when the SD tray is breaking, it's getting caught up on the little pins inside that contact the SD card and bending them a bit, and then that pin or pins are screwed up so it can't read the SD, and because it detects that there is one in there, begins to format and go thru the sectors when it gets to the messed up pin it craps out because it's not reading anything so it's saying the card is corrupt at that point. You have to send it into LG for a warranty repair. I had to do this too. go on the website, register your device, tell them the SD tray broke inside and it won't read the SD card or the SIM, and you will get a repair number within 24 hrs or so. Send in the device and you will get it back about a week turnaround time.
Good luck.

Most every time I've had this issue has been after an update or switching ROMs or kernel update and usually the issue is the kernel.
So basically speaking if you have an SD card corruption after any of these particular events reflash your kernel first.

I just bought a new Samsung 256GB microSD. I copied everything from my old card onto my PC, then onto my new card, and then put the new card in my phone. Android says it's corrupt and needs formatted. I try to format it and it always gives an error saying the command failed. Put the card back in my PC (which now can't use the card either) and performed a format (without the Fast option). Android still says it's corrupt and always fails to format it. So I put my old card back in the phone, and now it says it's corrupt too...

I had noticed that when I first opened the tray door it was being janky and wouldn't come out but a half inch. After reading this and getting the error for my old card too I decided to take the tray all the way out. Wasn't easy getting it out and now it's broken. Or already was broken. I tried cutting off the broken part and put the tray back, but now it won't even see a card or my SIM. So I've ordered a new tray. Hopefully that will solve everything... Unless my pins are jacked up as suggested earlier....

Well, got a new sim tray, and now it can read the SIM fine, but every SD card still says corrupt, and it fails to format it each time.

Out of warranty -- I bet the repairs cost half what I paid for the phone (like $200, crazy sale, two years ago). Sigh.

Any other thoughts on this?
