I bought 2 Sandisk 64gb Micro SDXC cards and put one in the pad ant the other in the keyboard using the SD card adapter that came with the cards. Everything was fine the cards were mounted and were also recognised in Windows XP SP3 when I connected the pad to my PC using the Asus USB cable that comes with the pad. The problems started when I had over 33gb of data to transfer to one of the cards, it was going to take a long time and I thought it would be quicker if I connected the Micro SDXC card directly to the PC using a USB adapter - one of those small adapters that I got with some 32gb Micro SD cards - I tried two, one was a Lexar LRWM01U-7000 (Rev A) and the other a SanDisk D33D21.
Windows said the cards were RAW and had to be formatted so I formatted them and ended up with cards of only 27.4gb. Asus support said "the TF700 has been tested with micro and full size SD cards up to a capacity of 32GB. You may find Larger capacity cards also work but these have not been confirmed".
The best help came from Sandisk who have been very good and quick to respond. They thought that the TF700T may not support 64gb Micro SDXC cards and even offered to replace my 2 cards with 4 32gb Micro SD cards. They told me that the adapters I used (Lexar LRWM01U-7000 (Rev A) and the other a SanDisk D33D21) support only MicroSD/SDHC cards up to 32GB, not MicroSDXC 64GB cards. They suggested I try again with a USB card reader that supports Micro SDXC. So I bought a Trust multicard USB 3 reader which supports MicroSDXC. I could now see all the unused part of the cards in Disk Management. I used the free EaseUSPartition Master to wipe the card and then set it as an unformatted active partition. I then used SDFormatter V3.1 to format the cards to exFAT and everything now works fine. (The Sandisk 64gb Micro SDXC cards come formatted in exFAT when new)
I have seen comments that the cards have to be formatted in FAT32 but I have not found this to be the case. exFAT seems to work fine on the TF700T. The problem lies with Windows XP it will not recognise an exFAT 64gb Micro SDXC card when it is plugged directly into a dedicated Micro SD slot on the Trust multicard USB 3 reader, however if you put the Micro SD card in the SD adapter that comes with the card and then put this in the dedicated SD slot on the reader Windows XP will now see the card (Windows 7 SP1 however will recognise the card without having to use the SD adapter). I presume from the comments regarding FAT32 that a card with this format may well be recognised by XP in the dedicated Micro SD slot on the reader but I have not tried this. If you want FAT32 then you can do this with EaseUSPartition Master but if you need files of more than 4gb you will have to use exFAT.
sorry, you need to rephrase that if you want anyone to read it. As it is now, it is way to compact to read.

Mmmm...lots of good info there thanx!
My dad and I bought a handful of these when they went on sale on Amazon. Mine worked fine after formatting, but both if his were saying the same thing yours did. I thought that was odd, it seemed like they were 32 gig cards. So I opened up a partition tool on my laptop and it turns out that Sandisk has over 30 gigs partitioned as unused space. All you have to do is delete the partitions and repartition the whole card on one partition and you'll be good to go. I used Fat32 if anyone is interested.

thanks for the helpful post. can you also run some sd card tests? i'm curious to see how true their class 10 rating is.

I ran a few compared to my Lexar class 10 and they performed about the same. ~10 write and ~30 read.

So I recently got a USB OTG adapter and it works fine with my thumb drives, but when I try using a microSD card with it, either through a usb dongle thing or a microSD to SD card adapter, it won't mount. The card is formatted in Fat32 but I have tried ntfs and Fat16. It is a class 10 card, but my class 2 won't work either.

Do you have any other microsd card to try? Or another adaptor?

Yeah, I've tried both the 8GB class 10 card that I have as well as a 1GB card of unknown class (It's older, so probably 1 or 2). I also tried both a USB to microSD adapter as well as a full size SD card reader with an SD to MicroSD adapter. I have the USB OTG Helper app by Ray of Light (in Play Store). I'm on Synergy right now, but I'm considering trying an AOSP rom to see if that is the problem.
Hey there folks, I was wondering if there was a special type of internal adapter to exist that would allow me to use 2, 64 GB micro sd cards in my phone. I'm looking for like a male micro sd card input-to-dual female micro sd card output adapter to connect to the female micro sd card input in the inside of my phone. It would use the same concept of the cable that is used to connect a desktop hard drive to the power source, then from the power source to the motherboard to make the drive primary or slave.... I think cuz I cant remember the name of that kind of cable?
Anyways, it would look kind of like this:

Why not just get a wireless hard drive? I have one and it's awesome.
Interesting - what brand do you have?
I have the SanDisk 64 GB Micro SD Card. It's the Class 10, grey and red-colored one. Iv'e never had any issues with my card, I just want to be able to add another 64 GB card without having to lug around a hard drive. There was a guy who had a similar kind of cable adapter setup but it was a male micro sd card input-to-dual female (reguar-sized) sd card output and his S3 was able to recognize his total memory of 128 GB's. How expensive, how big in physical size, and how big in GB size are wireless HDD's these days??

They had something like that before, can't seem to find it, you can try to contact them.
The price isn't cheap nor expensive.

The sandisk 128gb sd cards work with the s4, so this might be the easiest solution.
Yes, I realize the 128GB micro SD Card from SanDisk works with the Galaxy devices but I had initially asked the question way before the 128GB mSD came out this year. But still, if such a PCI type of card reader extender exists & it could let your galaxy device read (2) 128GB mSD cards.... WOW!

Ahh ha! I found it... kind of. It's basically this: http://www.aliexpress.com/item/2014...rd-Compact-Flash-CF-Card-Type/1889508912.html but has (2) strips coming off if it to tie into a set of dual micro SD TF adapters. This would allow you to input the male side of this adapter into the back of the phone/tablet, while you could potentially input (2) 128GB micro SD cards into each slot of the TF adapter. If I remember correctly, this guy's version years ago was similar to what I'm looking for but his had 2 TF slots each for 2 separate regular-sized SD cards and was able to read up to 128GB's or so with his. Im saying, take the same technology but add 2 TF adapters to input (2) 128GB micro SD cards instead and put the male end of the adapter into the female micro SD card slot into the back of the tablet/phone.

I bought a female USB to male micro USB adapter and I can plug a thumb drive into my phone. It works great for transferring files. Now I just need a splitter to power an external hard drive to see if my phone can read that too.
It also works with a wireless mouse and keyboard USB dongle.
Similar to this:

The only dual micro sd adapter I have ever seen was for the playstation portable. 2 cards into one memory stick adapter. I have used the full sd to micro sd with a 128gb card. Worked fine when formatted to fat 32.
Now that 128gb micro sdxc cards are availble, no need for that Macguyver stuff.
Now if you could find an microsd to otg cable adapter with multiple microsd slots, that would be a winner.
Yeah, now you're talking... with "the micro usb-to-multiple micro SD card slot!" Imagine if there was an OTG cable just like that with support for dual/triple micro SD cards each at 128GB's and that the OTG cable could read it on all Galaxy tablets & the S4 & S5's?! Ohhhh the insanity!! :what:
The iSheep would have heart-attacks!
I shall buy the first OTG triple micro SD card cable you make if you patent it and build it!

...or just get an OTG cable and format an external portable drive to Fat32 and duct tape it all together 2TB in the palm of your hand!
honestly, and thin film OTG ribbon cable with built in USB hub and multiple SD card slots should work it could be thin enough fold over and to be double sided taped to the exterior of your battery cover without being too obvious. this would add maybe 2-3mm overall in thickness. probably wouldn't be to durable though. maybe integrate it into a TPU cover/case to protect the thin cable...
but then we are starting to get ridiculous.
See, now you're getting somewhere with your "usb hub & multiple SD card slots" idea MadMan. I saw an OTG cable with dual female micro SD slots but it was too thick (like an inch thick) and had a super sticky/tacky tape on the back so one could attach it to the back of your phone or phone case. Just too bulky. Although, the Wifi idea is something to look into as well but I'm usually not in areas that have Wifi, thus the desire for more space without carrying around an external HDD.
I was looking for basically a male Micro SD Extension Cable (like you see below) with a ribbon type connection but has dual female Micro SD slots so it could fit between the back of the phone and front of the battery or back of phone and front of phone case... not for the extension cable to be put on the back side of the phone case.

Interesting
the psp adaptors work good but are very flimsy
Just get a dual interface flash drive, micro usb + usb PC storage. The sandisk ones are pretty cheap and go up to 128gb. Theyre really small too, dont stick out much on the phone. Plus the storage speeds are much faster than micro SD and all your files are on one storage. I use mine for screen recording games with no lag or stutter, whereas writing to the micro SD causes a lot of games to pause so the card can catch up. Easier transfer to PC or sharing with other USB readable devices too. Much more worth it than a dual micro SD port (though it sounds pretty awesome)
Ok, so ya'll can keep this post going but I have officially lost interest due to my S5 having caught fire last week! Due to the damages to the phone, being a very long-standing TMobile customer, and misinformation from a few folks.... I have now received a FREE upgrade to a Galaxy S8! So happy now! Now I'll just swap over my *still working, yet undamaged* 64 GB Micro SD Card but maybe get the 256 GB SanDisk Micro SD Card in the future just for the hell of it... cuz I can! :silly:
Here's a pic that I took with my burner phone of my S5 after it caught fire.

And how in the hell did you manage that? :angel:
I have an micro USB card reader (cheap aliexpress one but works great).
it works with all my SDXC cards up to 64 GB in my S7.
But with my new SDXC UHS1 [3] 128GB card it just doenst work in my S7.
When i plug the card reader in my desktop it works great (so the card reader isnt defect).
Is the OTG port not supported for UHS1 [3] 128GB cards?
edit:
my panasonic formats its as exfat.
Doenst otg support Exfat?
When I place SD card in my internal slot it works.
It seems the S7 doenst support otg exfat.
I took my sd card out to plug it into my pc with an adaptor so I could do some stuff with it but the pc refuses to read it, just says i need to format it! It's a sandisk extreme 128gb (which I believe comes pre-formatted and ready for use). I have a load of stuff on it which my phone can see perfectly fine, and i can access that stuff if i plug my phone into the pc. I just can't access it directly if I plug the card into an adaptor.
Could this be some sort of encryption done by the phone to the card causing the PC to keep asking me to format it as soon as I plug it in? I have *NOT* done an "encrypt sd card" on it so it can't be that. I dont know why else windows would not be able to read it.
What PC OS version?
exFAT formatted mass storages couldn't be accessed by some older OS's

win10
Windows10 has included support for exFAT.
I suspect your Sandisk micro SDXC 128GB comes pre formatted in exFAT,
My Samsung Micro SDXC PRO+ 128GB was preformatted in exFAT and has its own SD adapter included.
If you're using an adapter that was included with the Sandisk micro SDXC, it's possible that the SD slot of your PC is not compatible with the SDXC specifcations.
In that case I'd try a microSD USB adapter.

I am just using a tiny lexar card reader I must have had with an old lexar card, sd card goes in the little slot and it plugs straight into usb port. worked with my older sandisk 32gb card perfectly. maybe the reader is too old to work with the 128gb card.
