The 16Gb speed 6 does't see on Gtab !

I have 16GB Class 6,and 4GB class4,Fat 32 .Both work on my Nokia N8.
My Gtab was able to see my 4GB class4 after update 3389 ver.only.
Have anyone test on 16 and 8Gb yet??

I have a Kingston 16GB class 4 microSD card. My gtab sees it just fine. One time it didn't recognize the card. I popped it out and back in again, and the gtab recognized the card immediately.

I had the same thing happen with a SanDisk Micro SDHC card. I popped it out and back in and it was recognized.
Beyond that, I don't understand why a PC will not recognize the removable SD card when it's in the GTab. I'm used to connecting my Droid X (previously by Blackberry Storm) to my PC and treating it as a removable drive. I'm surprised I cannot do that on the GTab.

Someone mentioned that Winamp has an automount option that allows seeing sdcard2 from PC...

Mine is a Polaroid 16 Gig Class 2 Micro SD HC that the Gtab does not see. Do I need to buy a new micro sdhc card?

my Sandisk 8GB Micro SD class 4 card works. I am awaiting a pair of 16 Gb class 4 cards (Sandisk), I hope to have no issues with them.

I'll let you know once I have it. I'm hoping it will arrive early next week.
What brand of card are you using. I personally try to stick with Sandisk if possible.

faulty microsdhc card reader on TF700?

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

Can anyone post where to buy a MicroSD that actually works?
Thanks

[Q] 64GB MicroSD Class 10 slower than 32GB Class 10?

Hey all,
i bought a 64GB MicroSDXC Class 10 / UHS 1 for use in my HTC Sensation XE. It came formatted with exFAT which isnt an option on the Sensation so i reformatted the card to FAT32 (allocation unit size 32KB, was the default setting in the tool i used). Now, when i transfer files while accessing the card via card reader in my computer, the write speed is somewhere between 9 and 10 mb/s, which is fine. When i use the card in my phone though, the write speed for large files is only about 5 mb/s. The really odd thing: for the last months i've been using a 32GB card that also has class 10, and it gave me those 9-10mb/s while using it in the phone, too. Which means the bigger card is considerably slower than the old one, although the speed class is the same, and they both work at they same speed when plugged in in the card reader. Why is the new card working so much slower in my phone?

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.

Problem with Samsung 64GB microSDXC (UHS-1)

Hi
I read quite a lot about problems with UHS-1 microSDXC cards with other devices. I tried some of the possible solutions on my A700, but it all failed as soon as I try to do write access to the sd card.
Any one who has a possible solution on the A700?
BTW. I tried to use FAT32 and NTFS, both lead to the same error

Well, don't have one of those sd cards, however, you may want to use an app for your PC that specifically is designed for formatting SD Cards.
Try MiniTool or SD Formatter. You should be able to Google those and get the download links. Just remember, FAT32 is always your primary partition.
MD

The problem is not the file system. It works both with ntfs and fat32.
The problem is that the card is ejected as soon as I write some larger amount of data to it.

In the meantime I contacted German Acer support and received an answer: They claim that their tablet is only tested with class 6 32GB microsdhc cards. Also Acer clearly states the maximum capacity to be 32GB.
However I found an offer in the official Acer store of Acer Australia that offers a combo of the A700 with an UHS-1 64GB microsdxc from SanDisk (see http://www.acerstore.com.au/acer/store/index.php/iconia-a700-32gb-wifi.html)
So they promised to check this and hopefully they don't just delete this offer...
