Moto G 4g LTE - Sandisk ultra 32gb microsd card won't mount

[Arthemedus]

I picked up the Moto G 4g LTE version recently hopping on the fact that they added an sd card slot. Anyway, I purchased this http://www.amazon.com/SanDisk-Ultra-MicroSDHC-Memory-Adapter/dp/B007XZM6VG/
microsd card hoping for some nice expansion. But for some reason whenever I insert it it says damaged sd card, tries to format it, then says blank sd card, and basically loops this process. Now here's the weird thing, this sd card works fine (can read and write) in other people's phones, but just doesnt seem to work in mine!

I even tried my friends 32 gb microsd card and it worked (it was a slower class 6 varient),I tried *my* sd card in that persons phone, and it mounted and worked fine, the sd card works in my PC also.

I'm wondering if I need a slower speed card? Maybe class 6 or 4. Because I read up on another guys problem on here, his is freezing but he got a slower 32 gig card and now it works without a problem. I know he was having a different problem but I'm wondering if the phone is having an issue with class 10 cards.

Anyone having the same problem or have any idea what might be going on?

Hi,

As I mentioned on the "other guy"'s topic, I experienced this kind of issues with my previous phone, which were entirely solved by replacing my 32 GB Sandisk class 10 card with a 16 GB Samsung class 6 card. AFAIK, fast cards may cause malfunctions with some Android phones, because of the access response times.

Had the same issue. resolved by getting a different brand and lower class. all issues resolved.

I'm using this card bought thru Amazon for 17.99 ------Samsung Electronics 32GB EVO Micro SDHC with Adapter Upto 48MB/s Class 10 Memory Card (MB-MP32DA/AM)------
I have had 0 problems with it and high benchmarks, I use to use Sandisk but after multiple problems with multiple cards over they years I have completely abandoned them for Samsung and have yet to have a problem.

The problem comes from that, some cards won't fall back to lower performance level and thus causing issues for the device that it is inserted in.

Some devices does not have problem with that tough.

Another reason could be the file system used, but that's less likely, although not very rare.

And one more thing is that brands like SanDisk, Samsung, Kingston etc are the actual developers of the SD technologies and sometimes you may get a product that is using newer technologies, which often causes troubles.

I purchased same Sandisk micro card from Amazon as OP did. I got same results. It is sitting here on my bed with RMA on it to back to Sandisk. Just got a new speck sheet which was posted from the motorola forms that says the following:

Micro SD UHS-1 "The card will work, BUT the Moto G 4F/Lte WILL NOT SUPPORT UHS 1 - SPEEDS.

So it appears, a slower speed card is in order. I just had to purchase a Samsung 16 gb class 6 card. Would rather have had a 32 gb but could not find in class 6.

Thanks so much for the input and advice guys! I was too impatient to order another sd card and wait for it to ship so I went and bought a random 32 gig class 10 card from a brand i've never heard of called "Monster digital" and it works perfectly. So I'm not sure what really fixes it, if it's a brand thing or size or speed or what. But my change from my non working sd card was Speed: UHS-1 -> Class 10, and Brand: Sandisk -> Monster Digital

Regarding the SD card issue. I tried with three separate phones with a 32gb class 10 and and a 16gb class 4 -- failed on two of them, but works fine on one of the phones. So there is definitely a build quality issue ( and/or difference ) between the phones, aside from the mentioned 'supported sd card class.' Both of these cards work fine on all other devices ( pc/laptop/tablets including old SD card readers with adapters )

Wanted to give an update. Tested with four devices now ( 2 black, 2 white ) and First one ( white ) worked, next two did not work, but the fourth device ( black ) it worked to detect 32gb sandisk without fail. So there is _definitely_ a difference between them from device to device -- maybe even assembly line quality control issues depending on week of manufacture, who knows.

Very interesting (and puzzling). Do they all run exactly the same version of Android? Are they all exactly the same model (eg. XT1032) and the same internal storage capacity (8/16 GB)?

Oops, Moto G LTE is 8 GB only, sorry.

 

[interessant]

Yes.. exact same model/capacity and OS, all ordered within the same 1 week period ( two being RMA )

 

[NWKENT]

Can verify that the XT1045 4G LTE performs very well with a 64GB SDCard inserted internally, ALSO..with a 32GB MicroSD card inserted into the USB / Charge port..and runs both very well, and with both cards mounted..

I have a Moto G LTE on order, and am wondering if the various problems people are seeing are due to the file system used on the card: exFAT or FAT32. I would assume the newer SanDisk cards are formatted with exFAT. Does the flavor of Android on the phone support exFAT ?

Another issue I've found in the past with some other devices and ROM's is that if the card is formatted as exFAT, it might need be set up as a primary partition and not a logical drive (using MiniTool or some such).

But we'll see what happens when the phone & card actually arrive

As far as I'm concerned, my cards were all FAT32-formatted, both the malfunctioning SanDisk and the Samsung that worked well. Nothing to do with exFAT vs. FAT32 then.

Exact same 2 cards ( check my previous post ) , tested on 4 (four) MOTO G LTE , 2 Samsung and a Camera and a Tablet worked only on 2 of the MOTO G LTE's + all the other non motorola devices. It cannot be the formatting or even the make of the card if it's a compatiblity issue.

DId not work with same Samsung microSD

I'm using this card bought thru Amazon for 17.99 ------Samsung Electronics 32GB EVO Micro SDHC with Adapter Upto 48MB/s Class 10 Memory Card (MB-MP32DA/AM)------
I have had 0 problems with it and high benchmarks, I use to use Sandisk but after multiple problems with multiple cards over they years I have completely abandoned them for Samsung and have yet to have a problem.

I am getting 'Removed SD card' / 'SD card removed, Insert a new one' error by using exact same Samsung 32GB EVO Micro SDHC. I could not format it by using Moto, so I did a full format in my PC, Same result. The microSD symbol is UHS-1 (one capital U with '1' inside') - matched Amazon's picture.

Try a slower card (class 6 fort instance).

My XT1045 and sandisk ultra 32gb card both arrived, and they seem to work together just fine. Android version is 4.4.3. Card came formatted as fat32. Promptly unlocked the bootloader in hopes of flashing slimkat at some point

Just got my moto G 4g delivered today and My 32gb Sandisk Ultra (which I had for 2 years in 6 different phones) won't work. looked it up, saw this thread and I'm kinda sad that I have to buy a new sd card for this when I paid a premium to have the ability to use a sd card in the first place. Nonetheless, I'll take the safer route you guys talked about and try for a lower class speed. Just ordered a samsung 32gb (not the evo model) class 6 from amazon for about 19.25 after tax. it should be here on the 25th I'll let you guys know if it's a good one to use. I knew kit kat didn't play nice with sd cards but this is ridiculous.
