MicroSD Card problem - One (M8) Q&A, Help & Troubleshooting

Device: HTC One M8 Bell
Firmware: CM13 Nightly
Recovery: TWRP
Android Version: 6.0.1
Security Patch: April 2, 2016
So lets start it off like this, I had this 32gb lexar micro sd card that I have been using for quite some time. I decided it was time to get a new one so I went over to amazon and bought a well regarded 64gb patriot micro sd card to replace what I have in my phone. Once it arrived I unmounted the lexar micro sd and put in the patriot micro sd. I had this strange message pop up instead of it going oh hey lets set up your storage I got unsupported lexar sd card. I decided to tap on the notification and run the sd card set up stuff multiple times and just ended up getting errors that wouldn't allow it to be mounted. The phone is detecting the new patriot 64gb micro sd card as the old lexar 32gb micro sd card. I took it out and threw the card into my desktop system running windows and boom 60 gigabytes of micro sd flash detected everything came up fine it was partitioned and everything. So I decided maybe the file system is wrong and since I couldn't format in android storage settings anywhere until the card is set up I did it in the TWRP recovery where the card is fully detected and works fine. I can move files to and from it and everything without any issues but as soon as I go into android I get unsupported lexar sd card. After a while of having no luck at all I just decided to flat out wipe everything through recovery except the micro sd card and do a fresh android install and see if any system files in android were causing it. Here I am sitting in android with this brand new install with the message in notifications "Unsupported Lexar SD card" I have dug through system files tried wiping the cache for external storage. Nothing is working I have no idea. I really do not know what it causing this. Is there anything else I can try to see if I can fix this? Thanks.

Try formatting the SD card on your PC. Folks sometimes have better luck that way, than using the phone to format.

I have tried that already in multiple formats too, I ended up leaving it in fat32 since well that is the standard filesystem supported. I had no luck with anything I even reformatted it on my phone later with twrp because I thought the filesystem windows gave it was an issue. Nope it wasn't, I still have the same unsupported sdcard error. Something really weird though, I took out the new 64fb micro SD card that was having this issue and put in some ancient sandisk 2gb microsd that I have lying around, it worked fine. Android popped up with setup for the card. I still don't think something is wrong with the 64gb patriot microsd like twrp sees and and everything that it in it. Files can be moved around and so does windows just not android

"Fresh Android install" meaning what? Did you try a different CM nightly, or another ROM (like Sense)? Maybe just a bug in the particular CM nightly.

I reinstalled a newer version of CM 13 Nightly and before that I did an advanced wipe cleaning all partitions except for micro sd, usb-otg, sd-ext. I left the micro sd because it had the cm build on it. However yes I did also wipe the micro sd card card just earlier in the day, the problem still persisted once in android.

Have you tried a low level format ? and/or partition-table reset on your SD-card, it may fix it

SD card problems stemming from CM10?

Ok. Here is the scenario. Was on stock rooted LCJ. SD card working perfectly there. I flash to MIUI after doing a totally clean wipe and I'm able to access the SD card via the rom and PC when I sync. I go into recovery and do a full wipe and then flash CM10 with gapps. CM10 loads up okay but i notice that i have a notification that the SD card is broken and I should try formatting it. I attempt to sync the phone to the pc via USB cable but only the internal storage will mount.
I go into recovery and confirm that TWRP can still see the contents of the SD card. Having confirmed that TWRP can see the SD card I do another full wipe and then restore my stock rooted LJC. However, after restoring LJC the SD card issue persist. The phone does an error check but it doesn't fix the issue. It recommends that I format the SD card which I don't want to do and don't know if it will work. I attempt to sync the phone to the PC with the USB cable (which has always worked) but only internal will mount. Go into recovery and the SD card's contents are still showing up.
Also, I have a Kingston Media reader which I pop the SD card into and connect to the PC. Even using this media reader the SD card is still not being seen and the PC says the card should be formatted. Basically the only damn thing that recognizes stuff on the SD card is TWRP.
Anyone have any good advice on this topic? BTW...I have a class 10 64GB sd card. As mentioned above I never ever had a problem with this thing. Have always mounted it to the PC w/o a problem and has always appeared on every rom I have ever tried until trying CM10 today.
41 views and not one person has any input? guess i'm going to have to format the card and hope that works. really sucks balls. wish i at least knew for sure what caused this problem.
had the exact same issue. I had just purchased a sandisk 64 gig the week before and when it happened I had a hard time believing it was the card that went bad. I had no luck recovering anything off of the card but did format it and it has worked fine since.

its not the card...............its the formatting of the card. it has to be formatted fat32 for it to be recognized in cm10. stock format is exFAT
I had the same issue with my SanDisk 64 GB drive. I went back to Synergy and the card is recognized in that ROM. I can't get CWM or TWRP to recognize the card though. I get an error whenever I try to access the card from recovery. It sucks that I have to put anything I want to flash on internal memory

Trouble with 64gb sdcard

anyone have issues with their sd card?? i have a sandisk ultra sdxc 64gb micro card. i have to format this thing about every 8 hours! insert the card and the phone will not recognize it. i take it out, format it on the pc, insert the card, format it on the phone and its fine. the next day i go to access the card and its not listed in the file manager or in the recovery. in settings i click mount sd card, phone shows "preparing SD card" then nothing. i have to do the whole format thing over again.
any ideas?? is there a firmware update i need? phone is build # 1.54.401.10
doesn't matter what rom i use, i have tried 3...phone is fairly new.
i have done root, s-off, recovery, SU, busybox, etc. phone works great! other than the sd card issue.
thanks
figured it out

well i figured it out...did some sniffing around online and found a thread in the SGSIII forum. someone had a similar issue. apparently after doing a bit of additional reading, the htc one m8 does NOT like exFat cards. so while it CAN accept 64gb and 128gb cards, it doesn't really work right. to fix this i used easeus partition software, deleted the partition on the sd card, created a FAT32 one for 64gb, yes it will do it, and it works perfectly. hope this helps someone else.
I have problems with mine. I have a 128GB and haven't formatted it, and it works fine.
Thanks

64GB Sandisk SDXC memory card unmounts and corrupts after every reboot. Ideas?

Alright though I think the title says it all, I have a 64GB SanDisk micro SDXC card that I bought for my T-Mobile M8 and the card is formatted exFat using the built-in storage menu in settings.
My dilemma is that though everything seems to be correct, every time I reboot the phone or remove and reinstall the card or unmount the card, it can not be remounted without formatting it first and my PC doesn't recognize the card until it's been reformatted and remounted in the phone again.
I've read all about KitKat's ridiculous new sdcard policies and restrictions but I genuinely don't believe that my problem is related to the security updates that came with KitKat. I'm thinking there is another underlying problem.
I'm currently running ViperONE 1.8.0. Though I don't believe ViperONE is the cause.
any ideas or suggestions would be greatly appreciated.

I had same problems and i did format my sd card on my pc with win 7 in fAT32 using the "GUIFORMAT" free software, just do a search on Google, then I did put back my sd card in the phone, reboot the phone multiple time, copy files and after more than 3 days still work no problem

And this is with a 64GB card? I had it formatted to FAT32 earlier today and to my surprise it did not corrupt the card after a reboot but it DID have trouble re-mounting the card.
I'll try it again with the program you suggested and see if that changes anything. Thanks for the suggestion.

[LG D855][CM 13] Issue with sd card and what ROM should I choose?

Hi everyone!
Today I upgraded from CM 12.1. something to CM 13 and got a kinda weird bug, where google play services kept crashing, so i reflashed the gapps, and got another bug where the starting presentation program (don't remeber the exact name of the program, "guided assistance" or something, the one you get at the beggining explaining how to set up your device) kept crashing, making it impossible for me to continue using the device. Decided to restore factory settings (clicking between a crash and another xD) and everything works fine, except the fact that I can't use my sd card any suggestions? Any other info needed?
Is there a marshmallow rom with a working sd card?
P.s. I just read that is a issue that the developers are aware of, but i can't find anyone complaining about this error (the sd card not working) in the xda CM13 thread
Thanks to all!
MicroSD card support in CM13 ROMs is borked - the only thing you can do is wait it out!

Im on the latest CM nightly and I have no issue with my 64GB sd card. I used the built in format option and I seem to be fine

Does the current CM nightly that you're using support exFAT out of the box? The reason for me asking this is because on the 20151207 nightly, it was still complaining that the 'SD card is corrupted'.
FAT32 support for SD cards is fine on portable storage mode but when formatted as 'internal', people are still reporting problems as well.
I got that message as well but when I formatted I got my full sd card

If that is the case, then what file system is your microSD card using currently?
From what I can tell exFAT. My transfer speed was much faster then when I had to use FAT32. Is there an app that can tell me what format my SD card is?

Soorry if this is a stupid question, but what is the built-in format? Can I use an SDXC card from another Android device (Samsung Tab S) or this a special format option found only in CM-13/Marshmallow devices?

When you put a SD card in the phone on 6.0 it will ask if you want to format it. With 6.0 you can use it as portable storage or internal memory for more room for apps and such. I use portable storage but as of the last nightly I didnt have to format my SD card. CM fixed exFAT support in their latest builds.

Hey can you tell me your SD model? And filesystem? Just plug in your pc and see in the properties settings. Can you tell me your CM build?
Little update, I flashed Cloudy 2.5 and Gabriel kernel, thanks all
I figured out the SD card problem , i couldn't fix it for nothing until i did this.
FOR ANYBODY THAT GETS STUCK AT 20% or any other sd card problem with 6.0 roms
1. Backup all files on SD card (This will delete everything on your sdcard)
2. Install minitool partition wizard on your computer
3. Inset Sd card into PC with and adapter and/or card reader (NOT WITH PHONE)
4. Remove all partitions from SD card with partition wizard (Do not reformat) Be careful to only select the SD card
5. Place SD card into phone
6. Let the phone detect SD card and try to reformat
7. chose either Internal or Portable Storage
8. Enjoy because it works perfectly for me now.
btw. im running a LG G3 D850 ATT
there was a fstab issue with external sdcards, the fix has been merge already though.

Having trouble with my Micro SD card

I have an LG G3 D850 currently on Fulmics 5.2. I have never had this issue before but maybe someone here has run accross it. 2 Days ago I realized that my phone was not picking up my SD card memory. Today I decided to check it out to see what it was. First, I tried it on another phone and it picks it up just fine. All my files are there so it is not the SD card itself. I then thought maybe something got corrupted on the rom I am using but when I booted into recovery, it doesnt pick it up either. Could it be that the SD card reader on my phone is fried? What can I do to pin it down to the exact problem?

can still be the sd card backup your sd card and format to ntfs then to fat 32 on pc and see if that helps, also try a different sd card if you can. from personal experience a newly bought 128 gb wouldn't pick up until i formatted to a different filesystem than the fat series, or try a low level wipe on the sd card (extra careful with this one 1 pass only first 100,000 sectors)

But the weird thing is that I have been using this SD card for over a year now without a problem. So the first thing I thought was that the problem was with the SD card card until I put it into another phone and everything showed up fine. So the problem seems to be with my phone, either related to hardware or software.
To try your idea of the backup and format, what method do you recommend?
