I will try it I got another g4 plus and it doesn't recognize the card or says it is corrupt  will try it  

with my first one  i just kept mounting and unmounting about 20 times then it took it been working for 8 months now 

When formatted as internal storage, SD cards take a beating and it's not uncommon to see them fail.  

 

That being said, when a card, regardless of how it's been formatted, exhibits unusual behavior, I'd offload the data onto my computer and then format the card, but I don't think I could trust it.  I'd get another.  If a card is showing signs of corruption, it's time to replace it.  

Problem finally solved!  After more than a year I have solved the problem.  I got another (Non IBM/Lenovo/Motorolla) phone.  

I've learned my lesson; never buy anthing else from these people.  They don't stand by their products.  Goodbye and Good Luck. 

Moto Sr Moderator,

 

Have you not read the other posts in this thread? It is obvious that this is not an issue of SD cards taking a beating. The issue is that SD cards will not work in the Moto G phones as internal memory. Period. And they are not stable or reliable even as external memory. Motorola owes its MotoG customers apologies and refunds.

That's funny I have a 128 Samsung memory in my g4Plus and it's been working as internal memory for 6 months now ?? 

i had to mess with it at first but once i got it to take it it is Fine 

Hello everyone.

I am writing to inform you that i found a way to work around the problem.

Reading everything i found on the net, i managed to restore all my data.

I think that this means that the card is not actually corrupt.

 

The procedure is as follows:

 

1. DO NOT DO ANYTHING ON THE PHONE! Do not factory reset, do not erase, do not format. If this happens, no restoration can be done, as the key to decrypting the card is lost.

 

2. Connect the corrupr card to a windows or linux pc. It will not be able to read it probably, because it is decrypted. It will only show the existence of two particions.

 

3. Use a cloning tool to make a clone of the card. I used WinImage. It doesn't matter that you don't see anything in the card. Datta is there, but it is decrypted and therefore can't be read by anything but the phone.

 

4. After opening Win Image, go to Disk/Create Virtual hard Disk Image from Physical Drive (reads all card data as raw in a .vhd file).

 

5. Take another card with the same storage capacity as the corrupt one.

 

6. Connect the new card to your pc and again using Win Image, go to  Disk/Restore Virtual Hard Disk Image on Physical Drive. This will copy the clone of the card to the new one. In my case i had a SunDisk 16Gb card and i bought a Transcend 16Gb card. It worked perfectly, despite the difference in the brand.

 

7. Insert the new card to your phone and everything is there. All of my photos, videos and apps. My phone recognized the missing/corrupt SanDisk 16 Gb external card, as internal storage.

 

8. Back everything up, and buy a phone with more internal storage next time.

 

That's what i've learned.

 

The whole "set sd card as internal" thing is at beta stage i thing...but with a phone with 8Gb of internal storage it seemed a good idea. But sd cards are not intended for such a use.

 

Hope all this was helpfull.

Moto ZPlay and it just did the same thing. 

This was an AWESOME workaround with this crap Moto G Play. I have a SanDisk 128gb Ultra Pro and using it as internal memory beat up even a top quality card to the point it wouldnt read it anymore giving me the common "Sandisk Card missing, please reinsert" and rebooting didnt work. I should have listened to those posting when i thought my Transend 128gb was the problem the first time this happened 3 months ago but it's the phone not being able to handle Micro's as internal memory.



I tried every software to recover but it's encypted as internal and can only be read by the phone, I even made a mirror MicroSD that didnt work. But once i verified with EaseUS Data that my 57gb of my data were readable and on .SWF shockwave files. I figured i'd give this a try.



I used a VIVTAR 5-in-1 multifunction card reader stick (VIV-RW-7100) with a built in micro USB that i just plugged right into my MOTO but surprisingly it took it right away so I'm backing up all my data to Google Drive that wasn't backed up over the last week before sliding it as internal memory again. additionally only issue is that it's creating all duplicate photos and videos to Google Photos but that a small price to pay so i can backup everything else including all my app data that wasn't backed up yet..apps reappeared too. Thanks again!!!!

I have this problem with a 32Gb Sandisk card formatted as internal in a moto G3 with 8Gb RAM. Happened shortly after marshmallow upgrade to 6.0.1

 

Card won't read after power off/on,

Card won't read inserted into phone via external reader

Of course card won't read on PC, although data recovery software recognises partitions

 

Have tried to clone the corrupted Sandisk onto a PNY 32Gb SD card, but it seems that there is not enough space on the new micro SD card. ?!!

 

Motorola online chat has just told me to reformat the unreadable card

 

It would be nice if a large international company could come up with a better response to what is an extremely annoying (and apparently fairly common) problem. 

 It is fairly impossible to use a phone with less than 4Gb spare memory without an SD card.
