really odd MicroSD problem

well been using the standerd 2gb sd card with my phone fine but upgraded toa 16gb card over the last 2 days...
soo i took the files of my old card using active sync
put the new card in the phone.. formatted it then transfered the new files.. gets to about 250mb then says... write protected please make sure the file is not in use bla bla.. sometimes it gets to 2gb but it always does it on a diffrent file and none of them are protected and the card shouldent be as its formatted and 16gb
can anybody help or does anybody think its a duff card?
any help would be much greatful!
Thank you
Sam Morgan

forgot to say the sd card quick fix is installed aswell

Don't use Activesync to copy the files - use Disk Mode.

tried using disk mode but still get the dodgey things of writing a certain amout.. not being able to delete some files.. even after i just put them on there... any way ive orderd a new class 6 16gb card from a data and hopefully should do the trick as i think this chinese crap is duff

your case sounds awfully familiar to those of the people who bought the "16gb usb pendrive" from chinese resellers, which were actually 1gb pendrives with modified onboard chips to make it appear as 16gb devices. The first GB you copied was fine, but whenever you tried to access data over that limit wyou would obviously get errors. In this case, if you bought a cheapo card from an "unkown" seller, he probably gave you a 256MB hacked microsd.

also worth making sure the card is formatted to fat 32,4096 block size for best results.

thanks for the replies guys...
samsamuel: i used the formatting tool on the phone
oh just tried formatting again it saud card is broken or damaged then tried againa and let me format it... must be broken then

Hi, did u fixed it? I faced with same issue. Im looking for solution, will let you know if i get some.

Even I have the same problem I called customer care and they told me to visit service centre. I also tried factory reset but no use

Same here. I tried format the SD card in a Mac and a PC, tried again with other cards, but I have the same (frustrating) result. The only thing I didn't try yet was restoring the device, and I don't know if is a good idea (seems didn't working for any other person with the same problem).

Hi did you get that resolved?
I am having the same problem. I was using my old MicroSD Card. After the update for Android 6.0.1 it appeared a message saying that the card was corrupted or something like that and i might need to format it. I try to do so and and error appeared while formatting it as Internal so i remove the SD card and restart the cellphone and tried to do it at least as External Storage but i got the same error. So i bought a brand new MicroSD Card Class 10 32 Gb and had the same issue. I did a hard reset and start over and i have the same outcome.
All my SD Cards that i tried to use got recognized on my friends cellphones. Moto G Turbo, Moto G 2nd i got a Moto X play. The difference between them and i is t hat i have Android 6.0.1 and they 6.0.
Does somebody found the solution to this issue? . Which version of Android do you have 6.0 or 6.0.1. Everything got screwed up after the update.
Additional Details:
1. After the error appears the SD card is not being read anymore even if i eject it and insert it again. So i erased the Media Storage Cache and External Extorage Cache, restart the cellphone and put back the SD card again and i got recognized with the message that i need to format it. I try too many time reproducing this issue and i always got the same frustrating result. The SD cards were formatted on Mac and PC and also other Motorola phones and Same ****.
2. Called Motorola Services Desk on USA and LATAM. One of them told me to restore the cellphone to brand new state. I did it and same ****.
3. Am so sad for this not much information available

The same issue is there in many custom ROMs as well. I feel it's got something to do with 6.0.1 rather than the sd card itself.

Will try to factory restore and let you know !

No. I just bought the Moto X play. I was working fine with an Old SD Card. After i upgrade to 6.0 to 6.0.1 the SD Card is not read anymore and showing errors while format it internal or externally. I bought a faster card class 10 and same error. The thing is my friends with no update can read my cards without problems using same cellphones.

My sd card went crazy too after 6.0.1 though after a few tries I did manage to save everything on it into my pc using the sd card adapter. Then I did the slow format in Windows and put it back into the phone. So far it seems working fine.

I will try on a pc...did that on osx with Parallels Desktop...no go!

I have had the same issue as some above. Went wrong two weeks ago when the latest OTA became available from Motorola. The moment the phone restarted I received a warning that the microSD was not formatted, which had been previously set up as internal storage. I am 100% certain that it was the upgrade to 6.0.1 that did this, and not anything physical. I've tried approx 20 different methods to try to format it, both in the now-rooted X Play and on my PC, and even when it appears to be successful it actually isn't. Windows 10's diskpart will show the partitions, whilst most will not. It's as if the card has somehow become write-protected. The 128gb card was not cheap, so if anyone has had the same issue and has a solution, please give any tips you can!

Hello any solution for this ?

I'm willing to try and flash the 6.0 stock. Reporting here asap!

I need a fix for thisssssss! SD Card is not garbage now is it?

no way
sorry guys, bad news! I downgraded to Stock Android 6.0, it didn't fix the problem.
will try with a brand new sdcard...to see if the mxp is somehow very picky...or more simply the sdcard reader is damaged

hi guys!
i have the same issue with new 64 Gb microsd card. did anyone get the decision?

Disappearing microSD

Hi, I recently stumbled upon an unpleasant issue. I got xt1562 (stock 6.0.1 EU, no root, no cwm) and sandisk ultra 64gb. Sometimes (I fail to identify the source of issue) the memory card just disappears and the phone doesn't see it. Since the card is formatted as internal, i cannot take even pictures or download anything via browser. SolidExplorer doesn't see it in the list of storage as well. Restarting the phone or replugging the tray helps for an uncertain amount of time, the card becomes visible and then disappears again. I looked for obvious answers, but it is something special (not mentioned here or in google to my best knowledge).
Does anyone know how to solve the issue? I would appreciate any comments as well.
Thanks.

I had this same problem, but it solved by itself.

for this particular reason I stopped using the memory card as internal storage.

I had the same disappearing issues before but since I did a slow format in Windows, the problem seems to go away. Never had any disconnect or disappearing issues again until now.

I'm getting exactly the same issue. I'm using a 128gb card formatted as portable storage (exFAT ). I know when the issue starts because taking a picture with the stock camera app causes it to crash, and spotify complains about there being no access to storage. The card is being detected by other apps and Androids built in file explorer. I have to restart the device to cure the issue.

I have the same issue since updating from 6.0 stock to 6.0.1 stock.
What changed? There must be a reason for this behaviour.

Same issue here too after updating to 6.0.1 ota. Have to restart for it to fix itself. I'm beginning to think it might be linked with charging but not certain yet.

Searching the net it seems that Samsung users are on 6.0.1 are having the same issues. Google must be aware by now.

I fixed it with a different kernel.
Phoenix --> permanent dismounts
Optimus --> works

Well, stock ist stock.
After updating to 6.0.1 I had no dismounts with stock kernel, but I didn't use it very long.
I flashed Phoenix kernel which resulted in lots of dismounts, this was fixed by Optimus Kernel for me.

I used to be have the same problem with a Sandisk Ultra 128GB.
I need to backup all files in windows and format it to back to normal.
This problem appears every 30-40 days after formatted.
The problem was finally solved by buying a new sd card (samsung pro).

Well, I was too fast reporting it fixed.
I still get unmounts. Not that often but it ain't fixed.
Never had a single unmount with 6.0.
Actually thinking of going back as this sucks balls.

I tried formatting my card back to exFAT. The dismounts were as much as every 10 minutes. I have now formatted the card back to FAT32, of which i had more stability, but this time I have started fresh with a completely empty card. Formatted in gparted then straight into the Moto. See how this goes.!!

Me too had similar issue after the latest ota update.
Everytime When I connect phn to PC via cable SD card disappears. SD card will not show in PC and phn. I need to restart phn to get it back. I'm using SD card as portable.
1st I formated the phn. But still the problem occurs
2nd I formated SD through PC. Result was successful. Now the card is OK not disappears while connecting to pc

This is the exact same issue I had since stock lollipop. I updated it to 6.0 since I though that this was the reason, It worked for half a day before it stopped and even on 6.1 it doesn't work.
For the record I also have Sandisk 128 gbs class 10. The only message I get is "Corrupted SanDisk SD Card”.

Some solved this problem with slow format option on PC.

Still no progress in resolving the issue
SInce my last post, I have formatted the card as external. It worked fine until i filled it up to 10gb (out of 64gb). Now I have exactly the same issue. Does anyone know how to let Google, Morotola know about it? Is it covered by any guarantee? I start thinking that I am back to 2007 with first android versions

Galaxy note 3 doesnt recognize my SD Card

Hello all,
I have been using Galaxy note 3 for the last 3 years or so, have rooted it, installed AOSP and stock ROMs (including the latest Note 7 ports) on it. So I have a fair understanding of how the phone works, and am able to work with errors on a very comfortable basis (sometimes, with help from other XDA members as well).
Now, here's where I am stuck. I was running a Note 7 port ROMs (Phronesis and Magma-NX), and also ran an AOSP ROM. Since last week, my phone has not been able to recognize my SD Card (I have two cards: one, a 32gb card, and the other a 128gb card) on either of the stock or AOSP ROMs. It says: Corrupted. So I begin to format the card (both of them) on the phone itself, and I keep getting this message when I try to format my SD Card via phone:
thread binder_7 gave up waiting for partitionPublic after 180000ms
The SD Cards format properly on my laptop. The end result is my phone doesn't recognize any memory cards, and I basically end up working with the internal storage of 32gb. I havent encountered this error before, and I have no clue about what to do. I have tried googling it, and Google gives me a result for partitionPrivate and not partitionPublic. I dont know if these are the same things or not, and in either case, I absolutely dont know
what to do.
Can anyone suggest/guide as to what should I do?

I had an issue where my phone wouldn't see an SD card unless it was given a name when attached to a PC, might be nothing to do with it but could be worth a try?

Sorry buddy, but didn't quite understand when you said" given it a name". How and what did you do to name your SD Card? I will definitely try anything to make it work

I have same problem and I never fix it. I follow so many guides from Google without luck, seems that my N3 decide to not read external memory any more.

Hey buddy, in that case, what did you do? Did you end up using a lot of cloud based storage on your note 3?

I guess that is probably working good for you; do you have your photos and videos setup to be directly posted on the Cloud then?

Definitely, you have various options how to upload directly, with mobile plans, only with WiFi, only on charge.

Awesome, thanks buddy.. Did you try to have someone look up the SD Card slot to see if it was damaged or if it needed a replacement?

Just to check, have you tried to convert your sd cards into internal storage (adoptable storage) before the problem occurs ?

@zlazaar I'm not sure bro.. All I did was just copied one app from my internal memory to the external SD Card. But I didn't jot try to convert Tele external SD into an internal memory.. Do you think that's what the issue is here?

Can you try this please :
- Format one of your sd cards using your PC (use this recommended tool)
- Make sure you choose FAT32 as file system before format
- Check if you got the correct total size of the formatted sd card
- Shutdown your phone, put your sdcard, boot directly to recovery
if the recovery is able to recognize the sd card with the correct total size, then you don't have a hardware failure.

When you connect it to a PC, when viewing My Computer as it used to be called, you can see all of the drives, C:, D: etc, on that screen if you right click above your SD card drive select rename, it should be under removable drives. A long shot but also an easy one so worth a punt.

@zlazaar Hey buddy, so I downloaded the SD Formatter, and did a quick format (should I have done full Format - if yes, which one - Erase or overwrite). I also tried the Format Size Adjustment ON and OFF.
I have 2 SD Cards, one 128gb and the other a 32gb. The SD Formatter formatted the 128gb card as an exFAT, and the it formatted the 32gb card as a FAT32. However, TWRP still didn't recognize either of the cards. I still dont have the cards running on the phone..

Samsung SD Card corrupted | All Kernels

Hey guys, I've run into a little of an issue. I flashed various kernels on my AZMPM with stock android 8.1 , however none of them is correctly supporting my 64GB Samsung Sd card. It just says corrupted. When I format it by pressing the pop up,it says SD card ready ,but then again it says SD card corrupted. the first time I popped in a 16GB Samsung SD card ,it gave the same error,then I formatted it on my phone itself,it gave an erro,I popped out the card and popped it back into the phone and Voila! No problem! Everything is fine. However the same is not happening with my 64GB card, it just says SD card corrupted! fix now! I fix it then again error.
Please help.

1. Try reformatting the sd card via pc with correct format
2. Check if the card works correctly in some other phone
3. If the card gives you same issue in other phone then kindly replace it.
4. All the kernels out there are almost stable for daily driver now so maybe its not a kernel issue now.
5. Try flashing your stock firmware again, maybe it would work.

Thank you for replying ,but there is no issue with the memory card. I have gone back to stock rom plus kernel,with the 20th Sept OTA through TWRP file,now there is no issue with the card. Am I doing something wrong? I just flashed a kernel on top of the stock rom through twrp that gave me max clock speeds of 2208mhz on the bigger cores and 1800 something on the smaller cores. Everything was fine but the memory card.

Even i cant explain how this happens to you bro, but remember to wipe cache/dalvik cache even after flashing a new kernel or rom (not necessary for kernels but as a clean & safe side i recommend )
