No luck with class 10 SDHC 64gb

I got a 64gb Sandisk Micro SDHC class 10, and have had no luck getting it to work. It came as exFAT, no luck. I formatted as NTFS, no luck. I formatted as FAT32 using a tool I found since Windows can't do beyond 32GB for FAT32, still no luck. Not sure what else to try. The 64gb Sandisk SDXC class 10 card I got for the dock works just fine.

Oh, and I should mention, I do have .26 firmware. And rooted as well (bootloader still locked though), but that shouldn't matter. I'm doing another reformat of the microsd now using a different tool, but I doubt it will work. I should also mention that it is recognized by my PC using its microsd slot without any problem.

Made one additional check, and placed the micro sdhc into a USB card reader and plugged that into the dock. The infinity had no trouble seeing it then. It simply won't mount it when it's placed into the micro sd slot on the tablet. I don't have another micro sd to test, since that could indicate if the slot on the tablet is bad, but given all of the issues folks are having I'm guessing there are more bugs that will hopefully be addressed in another firmware release.

I included this info in a later reply, but wanted to keep this entry "complete"... I just tried this. Put this 64gb Sandisk MicroSDHC (class 10) into my Galaxy Note, which was able to read it without a problem. I then erased and formatted it using the Note, and put it back into the Infinity. No luck, it just quickly flashed the "preparing" message again, but that's it. Since I had to take out my Note's microSD to try things, I went ahead and tried that card in the Infinity, just to make sure its reader actually works, and it had no problem with it. That card is a 32gb PNY SDHC. So, it just does not seem to want to read this 64gb Sandisk Micros SDHC (class 10).
[Asus Transformer TF700] Thats OK:
Samsung 32GB class 10

...is the card inserted into my Infinity.

It's a pretty fast read card plugged directly into a PC.

Is there an app that measures read\write IO for sternal SDHC micro cards?

Im using a Centon 16gb Class 6 and it seems to be working. Just got the TF700 today, popped it in so not much testing other then being able to browse files on it and nothing going on fire.
[Asus Transformer TF700] HeartWare42:
Unfortunately, it doesn't work in my tablet, so it seems like it's not a sure bet...

UPDATE: The card I received was not the card I ordered. The card that doesn't work is this one, which is a UHS-1 card (it has the "1" inside the "U" on the lower left corner of the card).

Running Kernel 2.6.39.4

Build number IML74K.WW_epad-9.4.5.26-20120720

Pad EC version PAD-EC20T-0216

It works in the dock using the USB port, so the card itself is fine, but when I insert it into the tablet, the "Preparing external storage" (or whatever) briefly flashes in the status area, and no card is mounted. The same happens if I try to manually mount it using the Settings.

The same card works fine in the TF201 tablet...
[Asus Transformer TF700] okantomi:
Is it possible to format it in another android device/phone? Sometimes that makes a difference.
[Asus Transformer TF700] HeartWare42:
How do I format it in an Android device?

My tablet is rooted, so I have root access and can try out things, but I don't know how to investigate it. I have installed a terminal emulator (command line prompt) and am used to working at the command line in Windows, so I am not afraid to do so, but I don't know Linux enough to figure out myself how to format the card in the device itself.

I don't mind it formatted in ext3/ext4, as I will only use it in the tablet (I'm using my exFAT-formatted 128 Gb SD card to transfer large stuff onto the device, and DropBox for smaller files).

---------- Post added at 03:54 PM ---------- Previous post was at 03:48 PM ----------

I've just discovered that the card I ordered was not the card I received. I received this one instead, which is a UHS-1 card, so this may be the reason it doesn't work in my TF700 tablet.

Lexar 32gb microSDHC class10

works like a charm in my tf700 and my husband's tf101

I ripped some DVDs -- plays well off the card in the tablet --- or in the docking stn with the USB adaptor that comes with the Lexar card,

they aren't cheap (canada) but if you catch a good sale,,,,,,sometimes half price

many thanks to this site ---- I have discovered BSPlayer which is awesome. the supplied player can't seem to handle the movies i ripped (I used H.264 setting) as sound is out of sync but BSPlayer is fine.....and I paid for the full version --- I like the volume enhancer as I am somewhat hearing impaired. I haven't sat and watched a whole movie off the card, but the bit I played was fine.

PS: I am a newbie (or noob) so most of you are discussing stuff way over my head...... I don't root or unlock or whatever....I use it as I got it.

I have a question, formatting to ntfs on the sd card would that allow you to transfer file sizes over 4gb ? I know before i wasn't able to do this on my phone said that andriod doesnt support file sizes over 4gb

2nd questions, i have micro SD in my tablet, i ordered my dock, if i put another sd card in the dock will i be able to use 2 sd expansion slots, will the tab recognize both or just one?

Thanks,
[Asus Transformer TF700] timrock:
1 - yes, as well as exfat. the recommended format.

2 - yes, you will have two different expansion slots.

That one should work. The UHS-1 (Class 10), however, doesn't work...
[Asus Transformer TF700] weathertom:
Any idea when UHS-1 will work?

Has anyone heard if ASUS will be putting out another firmware update to get the 64gb class 10 Micro SDHC cards working? I can use the one I bought as a flash drive for other things, but would prefer to use it in my Infinity rather than having to go out and buy another card for it.
[Asus Transformer TF700] bosotros:
Same here, I have the SanDisk 64GB UHS-1 that Amazon sold for $59.99 and it doesn't work no matter what formatting I use. I've even done a couple of low level formats and this allows the tablet to mount the card and accept files, but it still won't play videos.

This card works in the TF101 so it would be nice if an update could make it okay in a TF700.
[Asus Transformer TF700] weathertom:
Wow, you've at least had more luck than I. I haven't even been able to get it to mount (just briefly flashes the message that it's trying, then nothing). I've formatted ntfs, FAT32, re-did the xFAT, and even formatted in my phone (Galaxy Note, which was able to read it fine), but none of them worked.
[Asus Transformer TF700] hellalucard:
The SanDisk Ultra 16GB class 10 HC (red/gray) has been working for me on .26
[Asus Transformer TF700] bosotros:
The best luck I had was was formatting to exfat in Windows 7 but turning off 'quick format' so it does a low level (time consuming) format. After this it seems to work okay except for videos but I don't trust it will last very long before files start disappearing again, like what happened when it was new out of the box.

Here is a link to the card I got:

The model number is: SDSDQUA-064G-U46A
[Asus Transformer TF700] weathertom:
Yeah, it sounds like 32gb ones are as well from what I've seen. Mine is 64gb, and so far I haven't heard of anyone getting one of those (64gb class 10 Micro SDHC) to work. It works if placed into an SD adapter and put into the dock, but not if put directly into the tablet's micro slot.

---------- Post added at 12:37 PM ---------- Previous post was at 12:33 PM ----------

I tried a low level format as well (ntfs, exFAT, and FAT32; had to use a different utility for the FAT32 since Windows won't go above 32gb for that), but none worked.

Here's the link for mine...

I just contacted ASUS about the class 10 situation and I'm waiting on a reply. I'm sure others have done the same, has anyone received a response?
[Asus Transformer TF700] zabih107:
What does the class stand for? For example, how is a class 10 better than a class 6?
[Asus Transformer TF700] ToonSpirit:
I am currently using a µSD Samsung 32 GB class 10 (black card/blue screen printing) and a µSD Samsung 16Go Class 10 (grey card / orange screen printing), they both work great ;)
[Asus Transformer TF700] Rebelwithoutacause:
The class of an SD card refers to its write speed.

For an example: A class 6 microSDHC can write at 6 MB/s; a class 10 would write at 10 MB/s.

As for which class is better. That can depend on whet you plan on using your memory card for.
[Asus Transformer TF700] HeartWare42:
Yes. It seems like the problem is limited to the 64 Gb µSD cards with UHS-1 (maybe only ones fra SanDisc). No one seems to have one of these working in the tablet...
[Asus Transformer TF700] henbone11:
lol you got lucky or posted it late because now its $149.99. :(
[Asus Transformer TF700] Thats OK:
True!

The class ratings do get complicated I've noticed. Some cards are very quick depending on the device.

If I remember correctly most "sustained writes are tuned for jpeg or popular video formats.

A lot of cards are aimed at cameras vs data devices.

Bottom line is none of us may even notice read\write performance differences unless the card is dated or made with inherently unreliable memory.

I started buying Samsung cards and have never been disappointed.
[Asus Transformer TF700] Jdor:
What is the best way to format my new microSD card to NTFC or exFAT?

Can it be done on the Infinity or only on my win7 PC? Is there a recommended SW or just the windows format?

ASUS TF700T Gold
[Asus Transformer TF700] d14b0ll0s:
exFAT.

Don't do NTFS, it will give you problems.

The simplest way is to do a standard Windows format of your card.
[Asus Transformer TF700] timrock:
exfat has issues as well. When moving/copying items from the device to the microsd, it freezes and then reboots. A few users, including myself, have experienced this.
[Asus Transformer TF700] HeartWare42:
Me, too. I have read some suggestions to use FAT32 instead. I'll try this, when I get my Class 6 64Gb µSD card later this week (I don't store video files on the µSD Card, but on my 128 Gb SD card in the dock).
[Asus Transformer TF700] Jola013:
I have tried a Samsung 64GB SDXC Class 6 with virtually all formats possible in the TF-700T, no luck. (Grey / Red card).

[Asus Transformer TF700] BeverageNinja:
I've been pretty lucky with all of my Micro SD cards and flash drives as they all work without issue. I've copied very large files, 8GB MKV, from my flash drives to the tablets internal memory and watched movies off of all of the cards below with no problems, that includes my 64GB flash drive formatted to NTFS. I'm on .26 firmware.

I just sent my 64GB UHS1 card back to Amazon. Nothing I did got it to work, even when I did get it to mount, videos wouldn't play from it and folders were empty when I knew they had files in them.

I'm hoping Asus does another update to fix 64GB compatibility, .26 doesn't seem to have entirely taken care of the problem. Also hoping I can find a 64 in the meantime that will work (class 6 Sandisk maybe?).

I sent a note in, but have heard nothing as yet (submitted two days ago). I still have had no luck with my Sandisk MicroSDXC 64gb class 10 card. I've tried all formats (ntfs, exFAT, FAT32), and tried quick formats as well as low level formats. No go with anything. The card works fine in my phone (Galaxy Note), and works in the TF700T's keyboard/dock when used in an SD adapter, so I know the card is good. My phone's 32gb card works in the tablet, so I know it's slot it good. It just doesn't like this darn card for some reason.
[Asus Transformer TF700] GregFromUtah:
So it seems like the only 64GB microSDXC card that works in the Infinity (not the dock) is the SanDisk 64GB Mobile Ultra MicroSDXC Class 6 Memory Card (and it needs to be formatted exfat to work properly). Is that correct?

I want a 64 GB card for storing movies for my kids to watch, so I would also like to know if that class 6 card is fast enough to play movies from. Regarding performance, what has your experience been with this card in the Infinity (with the latest firmware)?
[Asus Transformer TF700] timrock:
no, it does not have to be exfat to work properly. In fact, i find that the best format is fat32. With NTFS and exFat, i ran into issues copying/moving stuff from the device to the card. Others have had this problem as well. It will freeze the device, and then reboot.

On the other hand, yes, the card can play movies just fine. Get BS Player.
[Asus Transformer TF700] Jola013:
It is not that simple, I have Sandisk 64GB Class 6 and Class 10 cards, and I cannot get either to work.

I believe that the FAT32 format has to be with a specific cluster size, or something like that, in order to work.

I will test and provide feedback.

So I just got my sandisk 64 gb micro sd class 6. I have a windows 7, so I just format using exfat(default) and allocation size to default 128kb? Is this the general consensus people are doing with a windows? Im having mixed results. Ill have to play around with this and see if I can use a different machine. I wonder why the infinity doesnt have a way to format the sd while its in the card.

UPDATE: Just realized that bestbuy sent me the class 10 looking at the packaging. Thats why I am having a hardtime with the infinity.... I guess its off to bestbuy I go. Now looking at the class 6 at bestbuy the price has gone back up to 149.99.. wow.. Ill try the slow format with the exfat with the class 10 once and if it doesnt work this one is going back.

Anyone hear anything new?

I'm still having no luck getting my Sandisk 64gb class 10 micro sd card to work inside the tablet. Windows sees it fine, the tablet sees it fine when using an SD adapter and inserted into the dock, but when placed in the tablet directly it shows that it's there but cannot successfully mount it (briefly flashes "preparing external storage" message, then nothing). I've reformatted in ntfs, exFAT, and FAT32, using quick and low-level formats, but nothing has helped. It also works just fine in my phone (Galaxy Note), and the phone's 32gb microsd works fine in the tablet (so I know the slot it good).

I sent ASUS two messages, but heard nothing. I'm hoping for another BIOS update soon.

I am having the same issues with the Sandisk 64gb MicroSD SDXC Ultra card in my Infinity. I can see it in my computer (Windows 7), format it to exFAT (tried FAT32 and NTFS as well), but when I place stuff on it, the tablet won't recognize it (it sees the card, but I can't play any vids, music, or display pics).

Best Buy sent me the Class 10 (SDSQUI-064-A11) instead of the Class 6 that I ordered ( SDSDQY-064G-A11A). They both have the same SKU number (4120116). Man, I hate Best Buy.

The problem is that sometimes it will still stutter midway through a video and then stop working.

Very frustrating; hopefully asus comes up with a solution.
[Asus Transformer TF700] junrider:
Same here, I got the class 10 instead of the class 6. I told them the SKU was the same but the model number that i ordered and on the online reciept page does not match the paper receipt I got with the SD microdisk.

When I tried the class 10.. it would take a few reinserting before it could be recognized, but failed after I took the SD out and put some movies. And maybe the infinity saw the SD twice out of 50 attempts of reinserting with nothing in the sd.

I'm facing the same problem with my hard drive Western Digital My Passport 500GB, when copy/paste files from the HD to my internal storage or to the MicroSD or SD it freezes also, it writes with about 22MB/sec and suddenly it freezes, in some cases the tablet rebooted itself, in other cases i had to perform reboot pressing the power button.

Guess it could have something to do with the way its formatted, although i am not 100% sure, but i read that from 64GB on formatted as exFAT would be standard, when connecting it to the PC mine sets NTFS as standard but maybe its option to format as exFAT.

Besides that i am using :

1) SanDisk 32 GB Mobile Ultra microSDHC UHS-I card Class 10 (red/gray) was not recognized before the update,(with version 9.4.5.22) but working fine after the update (version 9.4.5.26)
