Dock SD Adaptor card with micro SD will not read - Asus Transformer TF700

Got new TF700T 64GB. Trying all the features to ensure my unit is fine and come across one issue.
Inserting Apacer 2GB micro SD into Apacer SD card adaptor slot in dock and will not read. Comes up for a second reading but will not mount. Tried normal full size SD card in slot and works fine. Also tried taking Micro SD out of adaptor and putting into Micro SD slot in tablet and reads fine. Upgraded to .26 and same issue. Guess the Micro SD adaptor is faulty? It works fine in PC and other devices. Anyone else experienced same issue with SD Adaptors with Micro SD inserted into SD slot in dock?
I think my unit is fine and no need to return.. Thoughts?

yeah, it might just be the adapter. try with a different one. i had a 64gb micro in an adapter and it worked just fine.

I've had a microSD to SD adapter once that worked fine in my computer and my wife's laptop but nowhere else. That turned out to be caused, in all probability, due to some contacts being out of line and seemingly the contacts on our own systems were screwed up as well. The fact that it reads correctly in the main unit itself does suggest the fault lies somewhere in the adapter and not in your system.

Just tested my Sandisk 16gb MicroSD card in an adapter in the dock SD slot and it worked fine.

MicroSDHC not recognized...

When i got this tablet, it came with a 16 GB Lexar Micro SDHC card. The only problem is that my TF-101 doesn't recognize it even though it says preparing External Storage. I have a SD card adapter, but idk if it will work with a SDHC, so idk if I can format it to Fat32. Any ways to solve this?
Plug it into a PC if you can, and check what filesystem its formatted as. Then try reformat it to fat32.
And just to clarify, the "HC" part in SDHC simply stands for "High Capacity", which generally means SD cards larger than 2GB.
Some devices can have issues with certain SDHC cards (like my Wii and my N7B), but to my knowledge TF101 is not one of those devices.
Of course, that said, that doesnt mean some weird china-knockoff brand will work, but Lexar isnt that bad and shouldnt pose any issues imo.
So uh, yea, try reformatting it to fat32.
I've several MicroSD cards. One of them, a 16GB one, is unable to work with TF using internal slot. The card works in my PC under Linux and/or Win7, but NOT in TF using internal slot. If I plug an external SD reader in the dock USB port, card is read without any problem.
Of course my other cards work like a charm with internal slot. Why? I don't know.
My solution: use this 'special' SD microUSB card in other device and buy a new one with my TF.
My Lexar 32gb class 10 quit working suddenly as well...the past couple of days it has not been recognized when in the micro SD slot BUT when I put it in an adapter and insert it in my dock it will work just fine. The only thing I have changed was update to the latest OC ICS kernels...wonder if that's the issue?

No 64gig sd card support

I just popped out my SanDisk 64gb micro card from my TF 300 and inserted to my new 700t and nothing! External storage inserted notification is there but can't prepare it. No micro sd in file explorer. There is removable option sometimes but empty. TF300 with 64gb sd card support, TF700t with none. That's a bummer.

Asus Transformer Infinity TF700T and Sandisk Mobile Ultra 64gb Micro SDXC cards

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.

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

[Q] SanDisk Extreme Pro

Hello everyone. I have two problems and thought that you will be able to help.
I've bought sdcard (name in topic) to use it with tablet, partly as a swap memory and rest for storage. First I formated it to FAT32 and thought about checking how is it working before making a swap partition.
I plugged sdcard in but my transformer can't see it. It will just blink the info about external memory but that's all. Funny thing is that tablet responds with another sdcard and SanDisk is working with my Xperia Play. When I connect SanDisk to microsd adapter and then plug it into dock everything is working fine.
EDIT
Init.d problem solved.
Hi, I experienced the same problem with the sd card but with other brands. I tried 32 gig. class 10 cards by Samsung and Kingston with no luck. When plugged into the tablet they did not show, when plugged into the dock they worked fine. SanDisk is the only card I've had success with. The SanDisk that I'm using is class 10 but not the extreme pro. This tablet is finicky when it comes to storage media.

[Q] CM 10.1 + non-functioning dock SD card slot

Is there currently support for the dock's SD card slot in CM 10.1? The "nightly" thread doesn't seem to mention any problems in this regard.
For me, no SD card inserted into the dock's slot seems to be recognized by my TF700. I also don't get any entries in /dev/block.
The USB-port on the dock seems to work fine with USB-sticks. I was wondering if the non-functioning slot on the dock is a known issue with 10.1. Unfortunately I didn't test the slot with the stock firmware, so I am also wondering whether there might be a hardware defect.
Any input is appreciated.
Best regards,
eigengrau

Thank you for your answer. Sadly this doesn't seem to be it. The cards which I've tried were all formatted as FAT32.
The micro SD card, which is working fine in the interal slot, is also not recognized when inserted into the dock's slot using an adapter.
Is there anyone using QM 10.1 on his TF700 who can ascertain that the dock's SD card slot should work?

Try changing it from fat32 (I know if it isnt a stock kernal they arent able to use it) and try that. I cant remember where i read it from but some cm10.1 roms have difficulty with acknowledging the card. If all else fail try a clean download with your computer and slide it over to your tablet re-install (no dirty flashing lol) and see if that improves it. If you know anyone else with an infinity try it out with there pad to see if its hardware related
