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?
I just got my Sandisk Ultra 32gb microsdhc UHS-1 (Class 10) card from http://www.amazon.com/gp/product/B007XZM6VG/ref=oh_details_o01_s00_i00 today and my TF700 (rooted) is unable to mount the SD Card. Everytime I try to "Mount External Storage" from settings, it displays "Preparing External Storage" for 1 second and then disappears, with no SD card mounted. I've formatted this SD card using FAT32 (4kb, 8kb, and 16kb cluster sizes), NTFS, and exFAT file systems as well as using my phone (Droid X) and none of them have been able to be mounted on my TF700, although the FAT32 formatted SD card was able to be mounted/recognized by my Droid X. However, I'm still not even sure if it's a faulty card or a faulty card reader because my TF700 was perfectly able to recognize and mount my phone's 16gb microsdhc card (class 2 or 4) without any problems.
I've read in another thread (http://forum.xda-developers.com/showthread.php?t=1761861) that people were having some trouble using microSDXC cards, but the one I have is just microSDHC (UHS-1), so there shouldn't be any problems recognizing it. Does anyone else have any idea what the problem might be?

Everyone's having issues with microSD cards lol...Strange that SDHC and SDXC both aren't working right. Does anyone else have a SDHC card that is working? I can look at it when I get my tablet tomorrow, but I'm not sure if I have a SDHC card laying around.
I've just confirmed that my 32gb class 10 (UHS-1) card formatted in FAT32 works on 2 separate phones but is not recognized by my TF700 (32gb grey model). I've also confirmed that the TF700 is able to recognize and mount two separate 16gb microsdhc cards (class 2 or 4, obviously not UHS) formatted in FAT32. I'm beginning to wonder if it's just the UHS-1 compatibility that's causing the problem (maybe TF700's are not compatible with UHS speeds?) or if 32gb is too much for the TF700.
I have a 32gb microsdhc (and no at the moment I can't tell you anything about the class or speed or whatever) but I can say it works fine where my 64gb sdxc won't mount.

It looks to me like people are specifically having issues with UHS-1 cards. There's like a 6 page thread about it in the General forum. I know my 16GB microSDHC (not UHS-1) works perfectly fine.
im trying to buy one on amazon, can anyone post a 32gb that works

did you use SDFormatter to format the card? it might be good idea to do so prior to initial use.
My 32gb class 2 SDHC works fine. but my 64gb sdxc, which was fine in my xoom, is not recognized. Both are formatted the same
This is interesting. I have a dock and when I put the microsd into the SD converter, it works great. But if I take it out of the converter and put it in as a micro into the pad, the pad knows it is there, but will not mount it. This is very strange.
I found that the micro slot handles a 32gb card just fine, but not the 64 gb card. The SD slot in the dock handles all cards. I hope they come out with an update that corrects this.
Microsd card Lexar 32gb
I have the Microsdhc 32gb class 10 from Lexar i bought from amazon. This works fine, but just got my scandisk 64gb in mail today(uhs-1 class 10) and the tf700t doesnt recognize it like the rest of u guys. guess ill put it on my phone for now until they fix this issue.
I had the same problem with my kingston 16GB HC4 card.
My old 4GB HC6 card worked, but my 16GB not.
Reformatted with sdformatter and it didn't worked.
Changed the label of the card from "ASUS 16GB" to "16GB", and behold, it worked.
Tried to change the label back to "ASUS 16GB" and it is still working.
Strange problem...
Future firmware update will fix it.

Micro SDcard receptacle
I can top some cards not working. Got my TF700 Wednesday and was pleased that everything seemed to be ok. Started to insert Micro SD and discovered the slot was empty. No receptacle was in the slot. Card was flush withtablet body, had to retrieve it with a pin. Replacement on the way. Asus needs to give little stickers to QC inspectors so they can tell who lets this kind of thing through. UPDATE: Asus tech told me to use small object to press edge piece of metal inside MicroSD slot. Viola the receptacle is alive and working.

ASUS TF700T 32GB Grey
I have tried:
2GB SanDisk (normal Micro SD)
4GB SanDisk SDHC
16GB SanDisk SDXC
Also took the card out of my RAZR Maxx and it too did nothing in the device.
I also note that there is absolutely zero indication that I have even plugged anything into the slot. There no message "preparing media" that I have seen others post. I also do not see any option for preparing any external storage from the menu in settings.
I am wondering if the slot is bad, or the device has issues with SanDisk cards.
Detect it for a second
Hy, i recibed the infinity today and bought it with a microsd card y got from amazon
http://www.amazon.com/gp/product/B004G60AD6/ref=oh_details_o03_s00_i03?ie=UTF8&redirect=true
The tablet detect the card only for a second, but it goes way, the same problem as some guys that posted here.
Can anyone post where to buy a MicroSD that actually works?

I got a class 10 Patriot micro SD from Frys and it appears to be working fine.
Had same issue here with a SanDisk 32GB Mobile Ultra® microSDHC™ UHS-I card, after the update to version 9.4.5.26 it worked fine..
kind regards,
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.

Thanks guys!
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.

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.
