According to sandisk the 64 GB cards are pre-formatted as exFAT.

FAT32 can not be used for >4GB files (movies) .
[Asus Transformer TF700] bosotros:
Another major source of frustration with my android tablet.

I'm starting to lose my patience. I got the class 6 64GB Sandisk card and it was not able to mount, right out of the box. After every possible form of formatting I got various results, none of which could be called "working". Even FAT32 failed in both the micro slot and the dock's SD slot.

After doing a low level format in exfat it now works in the SD slot, but still not in the tablet. I don't know for how long it will work there. I guess I'll keep the card in hopes Asus will fix this issue with an update, and if they don't I can give it to my son who has my old TF101, which will accept this card with no problems.

All the irritations of this tablet are piling up on me. I guess at this point I need to do a factory reset which is a major pain in the ass. I don't expect the reset to help with anything except possibly some of the lag in File Manager and hopefully the browser. I miss my TF101, I really enjoyed using it.
[Asus Transformer TF700] Darnell_Chat_TN:
Yea, correct, as multiple people mentioned, the Class 10 cards are not working. Shame to miss a deal for class 10. My old Sensation can run the class 10, but the new Infinity can't :eek: .

I hope that they resolve this with the JB update.
[Asus Transformer TF700] xPSYCHOTRONx:
Well i can confirm that my samsung class 10 32gb works on my TF700 64gb just fine. I have run video, music, and comics off of it so far without issues.

I'm using the 32 GB UHS-1 class 10 version of this card and it before the update it had some issues, but after the update to version 9.4.5.26 it works fine now.

Any regular SDHC/XC will work in the dock, it accepts even from 2 GB , 8GB etc...

I think the 32gb class 10 are fine but when it comes to the 64gb class 10, then the infinity tab is having a hard time reading it.
[Asus Transformer TF700] psychoholica:
Ive been having a miserable time with a class 10 64gig SanDisk card ordered from Amazon. BSPlayer will try to play a .mkv but bomb within a second.

Can someone with a class 10 who thinks its working try this test. Copy a large file to the Micro SD card. In the file manager try to copy that file to the internal storage. Mine fails every time. Doesnt even start. I can play the same file(s) from internal memory just fine.

Have tried FAT32, NTFS, and exFAT. NTFS interestingly was 10x faster on my laptop as FAT32 or exFAT. If NTFS ever works use it!

Let us know if the test I described works.

My 128 Gb SD card in the (TF201) dock is a Class 10:

SanDisk Extreme 128 GB SDXC Class 10 UHS-1 Flash Memory Card 45MB/s SDSDX-128G-X46

---------- Post added at 11:54 AM ---------- Previous post was at 11:44 AM ----------

That appears to be the gist of it. My 32 Gb Kingston Class 4 MicroSD card works fine in the tablet.

My 64 Gb SanDisk Class 10 works fine in my TF201 tablet, but not in my TF700 tablet (the exact same card just pulled out of the TF201 tablet, where it works perfectly, and inserted into the TF700 tablet, which only gives a brief flash of "Preparing external storage" and no mounted card).

I have ordered a SanDisk 64Gb Class 6 card which should arrive later this week, and will report back if that one works in the TF700 tablet.

The crashes during copying to the MicroSD card in the TF700 tablet is present with my 32 Gb card, so it's not a Class 10/64 Gb problem, but a general problem (I believe my format for the MicroSD card is exFAT, so a reformat to FAT32 may solve that problem).
[Asus Transformer TF700] jtenniswood:
I made the same mistake of ordering the newer class 10 card rather than the old one, tried it this morning, it is recognised as a 64 gb card, and is formatted as exFat, but when copying files from the tablet to the card, the tablet crashed after 3.7gb.

On restart, trying the same thing, the tablet crashed again.

Ho hum, I've got a class 6 card on order, hopefully that will work or Asus will bug fix this issue soon.
[Asus Transformer TF700] rv666:
I have a 32 GB Transcand Class -4 & it works fine. Videos of almost any format play good. May be you can try another player and check the same .
[Asus Transformer TF700] junrider:
Apparantely, if you order the 64gb sandisk class 6 from best buy they give you a class 10. Both have the same SKU, I thought it was a mistake but when asked for an exchanged for the right sd card It arrived today just to find another class 10.... Think I need to complain to bestbuy.

UPDATE: Dont order the class 6 from bestbuy, theyll keep sending you a class 10. I already told them about the mistake so they can update the online description. I did trya slow format on the class 10 exfat, the infinity read it. But when I tried putting a file on the card, the infinity doesnt read it anymore and when I reinsert it to the laptop I lose format... wierd... Think Ill hang on to the sd card and hope JB will fix it or I have 60 days to return it for a refund or if they actual start carrying a class 6 64 gb.
[Asus Transformer TF700] troysbama1:
Unfortunately I can vouch for this. They just delivered my unwanted class 10 card about 30min ago. I'll probably just hang onto it as well.I'm not even going to try and make it work until JB.
[Asus Transformer TF700] bosotros:
I got the class 6 card (64GB) that most posts said was working fine. It's a non UHS-1 class 6. It doesn't work at all in either the tablet nor reliably in the dock. I tried formatting every way possible including low level. I have to assume that I got a defective card. It even exhibited bad behavior in my PC, it seems related to copying a lot of files or playing video.

I bought it from a third party seller at Amazon and paid shipping. For the defective return I also have to pay shipping. I don't like that, especially since they charged me twice what it costs to mail it the first time. If you buy from Amazon try to get it from them and avoid the third party guys.

I'm giving up on the 64GB until something changes. (already went through a class 10).
[Asus Transformer TF700] jtenniswood:
I just had the same experience with Amazon in the UK, the product clearly says class 6, but delivers a class 10 card.

Fortunately the returns are easy.

I hope Asus sort this out so it works with the class 10 cards, as the old ones appear to be very hard to source now.
[Asus Transformer TF700] clenz:
I received my 64GB micro SD card from Best Buy and of course it is the class 10 (ordered the class 6 online) like everyone else.

My Infinity definitely recognizes the card (exFAT) and I can load files. However, the tablet will reboot as I am copying large files, or a large amount of files. I was able to copy a 1.5GB movie without issue, but Mx Player shuts down every few minutes during play. I tried copying a 6GB movie and it keeps rebooting. When copying about 1,500 music files, I got about half way and then a reboot. The music files that made it over do seem to play fine.

I assume this is a driver issue and the new kernel in JB will resolve the issue. However, ASUS' track record is not good based on my Prime experience. For now I will hold out for a few weeks and see if any news develops on a fix for this before I return. I saw the class 10 32GB SanDisk cards on sale this week @ Amazon for $23 and I'm starting to think this is a better option.
[Asus Transformer TF700] jtenniswood:
Me too, was tempted by the 32gb version but will hold out for the 64gb if they fix the driver issue!
[Asus Transformer TF700] eaglearch:
So far so good with this particular card, I've copied some movies to it and played them with no noticeable lossage of speed.

[Asus Transformer TF700] HeartWare42:
The Class 6 cards that I ordered (twice now, from different affiliates of Amazon UK) were also delivered as Class 10 cards. It must cost them a fortune in return postage to keep delivering wrong cards to people :).

I'm waiting now for JB to see if it fixes the 64 Gb Class 10 issue. If not, I'll have to remain on my Class 4 32 Gb card, which works fine (except for the occasional reboot of the tablet when writing large files to it - this may perhaps be fixed by a reformat to FAT32, as others have experienced).
[Asus Transformer TF700] junrider:
Thought I read the class 10 64gb micro sandisk works with the dock... guess not. Did the same thing as the tablet, I really hope they fix this with a new update or the JB soon cause I paid for something I cant use..

UPDATE: Guess it works. I just let the sd card sit in the dock and reboot and the tablet saw the sdcard and I could sucessfully write to it while its in the dock and read.

32 GB class 10 Sandisk SDHC card. only works in FAT which is unacceptable on an hd device. Cant copy my large files to my HD device

Nevermind I was formatting on my Mac, had to use diskpart on my win7 PC to get it working. Issue has been resolved. Wifi copy to SD card is still slow but I guess has nothing to do with formatting. Also tried copying a 12GB mkv file and that worked as well. Thanks ASUS!!!
[Asus Transformer TF700] weathertom:
Does anyone have a 64gb micro sd working in the tablet?

I still cannot get a 64gb micro sd to work in the tablet. I have the Sandisk class 10 card. I've tried every format exFAT, FAT32, quick format, slow format, etc), but no luck. It works fine in my Galaxy Note phone, and will work in the Infinity's dock using the SD adapter, so I know the card is good. In addition, my 32gb micro sd, which I use in my phone, works fine in the tablet, so I know its slot is good. I ordered a class 6 card from Amazon, but they sent me the exact same Sandisk 64gb class 10 I already have, so no point trying that (already in the mail back to them).

I also just got the .30 OTA update, and was thinking that would fix the issue, but it did not. I cold booted an additional time after the update, but no luck. The card still behaves the same, the tablet recognizes there is a card in there, but when it tries to mount it nothing happens other than a brief status bar message.

So, does anyone out there have an actual 64gb micro sd card working in the tablet? If so, what is it, and where did you purchase it? I am considering just using this 64gb card in my phone, and putting the 32gb card from the phone into the tablet, but really want the space in the tablet. If I can get a card that works, then both devices can have a 64gb card (since this class 10 card does work fine in the phone, as mentioned).

Thanks.

64 Gb Sandisk MicroSD UHS-1 card works with .30 firmware

I can beat that! :p

64 Gb internal, 64 Gb MicroSD in tablet, and 128 Gb SD in dock :laugh: - all working fine (with .30 firmware).

Finally my 64 Gb MicroSD UHS-1 card works in the tablet. It's dead slow when copying to it (15 minutes or so to copy 3.5 Gb so far), but at least it doesn't crash and reboot during copy as it did before (with .26 firmware).

My 64 Gb MicroSD was formatted to exFAT using Windows 7. My 128 Gb card is also exFAT formatted with Windows 7.

So I can now finally keep all my Comic Books on the single 64 Gb MicroSD card - no need to split it up over two storage locations.

Only sad thing is the dead slow writing speed :crying:
[Asus Transformer TF700] weathertom:
So, it looks like the .30 update should have fixed things for me, but unfortunately it hasn't as of yet. I'll try some more reformatting tricks and keep plugging away I suppose.
[Asus Transformer TF700] weathertom:
Ok, now things are stranger. I formatted again for about the millionth time, with Windows 7, slow format. The tablet still wouldn't mount it properly. So, I then tried it in my phone, Galaxy Note, where it previously worked, but now the phone wouldn't mount it either. Said it was an unsupported file format, but I did exFAT, so no idea why it was saying that. I then figure what the heck, and tried to format it with the phone, which I'd done previously but that didn't help the tablet read it either. But, the format on the phone seemed to fail, since after it supposedly did it, it still couldn't read it. So, I popped it out of there, and put it back in the tablet. And now, for whatever crazy reason, the tablet successfully mounted it. I haven't rebooted yet, since I'm worried it won't remount again, but guess I'll do that in a second to check. Crazy.

Yup, as expected, I restarted and now it can't mount this damn thing again. Ugh. Is anyone else still having issues with 64gb Sandisk micro sd class 10 since updating to 30?
[Asus Transformer TF700] PolishPoet:
Same here C07 sn
[Asus Transformer TF700] bosotros:
I went through a class 10 and a class 6 SanDisk (64GB) and neither of them worked in the tablet (including after the .26 update). My class 6 I think was defective though. The seller, Blue Proton, refused to refund it because they said "The SanDisk 64GB microSDXC card is not compatible with the TF700." I don't know if they know something specific about the TF700 or if they were just saying that to avoid the return. It does seem odd that some people have 64GB cards working and many others don't.

The class 6 I ordered from Blue Proton was the one people here said worked. I bought it from a link someone left in this thread. But like I said, I think it was defective. I could format it and it would work for a short while and then it would lose files and refuse to play videos or write new files to the card. It did this a couple times on my desktop PC so I assumed it was a bad card but I'm not sure, after a week of trying everything I could think of dozens of times I kind of lost track of what I'd done last.

Ultimately Amazon got my money back from Blue Proton for me, but BP remained dickheads right to the end. I haven't had the nerve to buy another card but I really want a 64GB card that works.
[Asus Transformer TF700] weathertom:
Well, I ordered another class 6 microsd sandisk card from Amazon, via a different vendor, and they sent me a class 10 yet again. But, I figured what the hell, other people are getting these to work with .30 now, so I gave it a try, straight out of the package. And, it worked. I haven't tried moving much in the way of files yet, but it mounts and lets me copy some quick files without any problem. So, perhaps my old card just got messed up after so many reformatting attempts. It still works in my PC, and when used in a USB reader, so at least I can get some use out of it. So, overall, it looks like .30 fixed the issues, I simply needed to get a new class 10 card.
[Asus Transformer TF700] bosotros:
Can you give us a link to the card you got weathertom? I'm not gonna buy anymore 64GB micro's unless someone got one to work. I'll even wait till you've had a chance to use it for a while. The first class 10 I got worked right out of the box, for a few days, then I was in the reformatting marathon and eventually gave up.

Congrats on the success btw... I hope it lasts.
[Asus Transformer TF700] weathertom:
Here's the link to what I ordered on Amazon. http://www.amazon.com/gp/product/B005V7WIA2

If you're having trouble with your MicroSD card in your TF700, try formatting the drive to "ExFAT"

My Sandisk SDHC Class 10 32GB works now because I formatted it from FAT32 to ExFAT.

My only issue with this utility is that it only formats for Fat32. No way to use it for exFat.

I have no problem with any 32GB cards, nor would I expect any. I have a 64GB SDXC card in the dock and it's no problem. What I haven't been able to do is get a 64GB MicroSDXC card to work in the tablet, not the dock.

Thanks for the link weathertom. I'll wait to see that you have no problems with it and then order one myself. :good:
[Asus Transformer TF700] HeartWare42:
32 Gb MicroSD cards generally work well (I had absolutely no problem with mine). It's the 64 Gb MicroSD cards that have been causing a lot of headaches, regardless of file system (FAT32/exFAT/NTFS), but it seems to be fixed with the .30 update of last week (at least for exFAT usage).

It is, however, painfully slow to copy files onto it, although reading speed seems ok (at least in my very unscientific testing).

Not sure if anyone mentioned maybe someone can update first post.

Patriot LX Series 32GB Class 10 SDHC Flash Memory Card (PSF32GSDHC10) works fine as NTFS. I have had it formatted as NTFS since the day I bought the tablet at the end of August 2012 with no issues. The card is in the table I never tried it in the dock.
[Asus Transformer TF700] kanewangkw:

[Asus Transformer TF700] cferd:
This is an update on the above. 3 weeks ago I dropped the infinity, which resulted in the glass shattering and the top right corner, where it hit the floor, being bent. I sent it to Asus for repair and received it 2 days ago. On first boot, it updated the firmware to the one it had before, I think (9.4.5.30-20120907). Since then, both cards mentioned are recognized without issues. Don't know why it now works, maybe it's not the exact same firmware? To the OP, if you like you can remove the 16GB from the Not-working part of your list.

Already at insert?

Previous firmware versions either didn't recognize it (flashed "Preparing external storage" but no card showed up) (Firmware .22) or recognized it, but crashed during heavy writing to the card (Firmware .26). Firmware .30 seemed to fix both of these issues (but with a horrible writing speed).

JB should have fixed it for good (haven't tried measuring speed with heavy copying).

[Asus Transformer TF700] DLCPhoto:
OK, so I'm about to get the Tablet and Keyboard, to give me a lightweight laptop replacement for an upcoming photo safari to Africa. My main goals are maximizing both the capacity and transfer speed of this gear: I will be attaching my USB Card Reader to copy in Raw files from both a Canon 1D Mark IV and a Canon 7D, over almost a 2 week period of time. So there will be several thousand images. I will also be making duplicates of all these files by connecting my Seagate 500gb Expansion External HD (7200 RPM).

It seems from reading this thread that various cards are "iffy" in terms of whether they work at all, with some posts above indicating very slow performance for those that do. And I'll be buying a new Tablet, so will update to JB right away, so hopefully that will help.

1. My preference would be 64gb cards in both the Tablet and Dock: which cards are known to both *work* to begin with, and then provide the fastest speeds for transfer both in and out?

2. Is there a speed penalty for using these cards, or in other words, would I get faster performance with 32gb cards? If so, I could bring a few of these.

3. Will a 'straight' SD card work best in the Dock, or would a MicroSD/Adapter combination provide better performance?

Any experience reports greatly appreciated!
