I cannot find a solid answer to this question.
Say for example, the new EVO 4g LTE, or the SGIII
Even though they support 32gb SD cards, can they support higher if the card format (hc/xc) is correct?
The Galaxy S2 can support the 64GB SDXC card but I'm not shore about the EVO.

Cool. But I didn't know if it was absolutely incompatible, or if it is compatible but not recommended so that might be why they don't advertise it...?
Android phones do not support the default file system of SDXC cards (cards >32 GB) which is exFAT. However they will format these cards back to FAT32 and you'll be able to access the whole card as the partition limit for FAT32 is 2TB. There are limitations such as slower transfer speeds and loss of >4GB file support. You could try NTFS but I'm not sure how compatibility is for that in Android.
First post of mine, sorry if it is an obvious answer
The support to a file-system other than fat32 is kernel related and it is not tied to android itself.
For example, Doomkernel (in I don't get wrong) has inbuilt support for more file-systems.
It just depends on the devs and their will to patch the kernel in such way.
I am a user of Nokia N900 too and, in such environment, that is Maemo, the power kernel has actually been patched like that. By the way, according to the N900 user's handbook, there shouldn't have been support for sd card bigger than 16 Gb, but it was not true.

It's not advertised as those cards just recently came out and usually would need to undergo testing before manufacturers can guarantee compatability.

Hey guys.
I know that 64GB micro SDXC Cards are no supportet by our X10.
But has someone here testet this ?

Well, well, well...This would be an early christmas for me if it works. Have been forced to constantly streamline my music collection and dare I say with the new Xperia specs showing just 32GB internal storage and no micro SD card support, I sincerely hope Sony, that if it is true, it is a one off experiment. The average consumer hungers for more storage each time, fact.
Even the newer phones came out these few months only supports 32GB micro SD.
And by the way, I thought all Xperia phones are using micro SD?

Guys I' taking the plunge. If you see the youtube clip from the 1st post, all we need is to format it (probably with a SG SII) which should change the format to fat32 readable by our devices. If it should come to the worst I'll flog it on the SG II xda site or ebay.
Update 14/11/11 64GB micro SDXC Card works flawlessly with X10. Simply insert new card, phone will not recognise the format and will give message that card is damaged. Simply format (which is erase micro sd option on X10) and ENJOY!

mhmm, thats because they created a new data format for SDXC and we're reformating to SDHC standard? I'll think i'll get a 64gb Card Not like the 128gb versions will come out soon, right ?

It's not about the reformat. It's lower than that.
When id comes to SDcard readers, micro or normal, there are basically two types:
Type 1:
Hardware/firmware-driven, that uses it's own hardware to manage the basic functions of the SD-card and presents is as an UMS device (USB Mass Storage)
The benefit from those readers are less utilisation of the main CPU followed by higher throughput.
The backside is the limited support of what standards it can use.
Type 2:
Software/"dumb" reader. It'll just provide a "physial" connection to the underlying USB-system, and presents it "as is": a SD-card flash memory.
In this "dumb" mode, the Operating system must provide all the routines in order to communicate properly with the attached SD-card.
The benefit with those are full range compatibility with future standards, but it depends on software, drivers and the main CPU, which might result in slightly lower speeds and "sluggishness" as the IO-operations increases.
However, if the OS and the SDHC/SDXC drivers in question is poorly optimised, the hit on the CPU can be drastically high whenever a read/write occurs.
So, which one is prefered then?
It's up to the manufacturers of the hardware and the operating system.
In our case here, Android can use both UMS devices, as well as generic/default SDHC and SDXC flash cards.
In my opinion, the type 2, "dumb" readers, are the "best" ones.
The only limitations of what cards these readers can use, is only limited by the operating system and the kernel modules/drivers provided.
And the "load" on the CPU as generally so small it's often neglectable, provided the drivers and OS is well optimised.
Which type the X10 smartphone uses I cannot tell.
I simply don't know, but it sounds promising, as there haven't been any "corrupted data" reports from the few who are using 64GiB cards...
... yet!
If the X10 smartphone does utilise the type 1 reader, the firmware/hardware based one, it might "kick back", as data stored beyond the 32 GiB limit of the readers limitation, might just "disappear into the void", never reporting any errors.
Users might notice this first when they try to access the previous stored files and finds out the content returned are just a stream of nulls. (null = digital void, nothing, nada, true zero, blank)
If and When this happens, only time can tell.
Someone has to try fill the card "to the brim", and copy back the content verifying everything is correct and proper.
Not just the filenames and filesizes, but also the content itself. (Checksum methods should suffice)
Just to +1 the above post. When the manufacturer states a maximum card size its not what the phone can mount but what it can reliably use. There's a good chance that you'll have corruption if you continue to use it.
Anyone got any news on this?
Does it truly work with all 64 Gibibytes, or is only half of it useful as I suspect?

Then Phone Plays dead with a Corrupted MicroSD Card. Wont start up !
put the Card into SD Card and reade on my computer and that one says corrupted format. Need to reformat -.- But then "Computer cant Format that card" -.-
AND the Card gets ****ing HOT! nearly burnt myself! more than 50°C for sure! Also only shows 30MB space! But i had over 40gb data on it! so its a real one!
Guess i'll got an defective Card -.-
But about the Read/write values. had something like 6-7mb write and 30mb read.

Sd cards > 32GB is called SDXC cards. the smallest is 64GB. They typically come pre-formated with exFat which our phone doesn't support. You will have to use PC to re-format it into FAT32 using large cluster size before you can use it on the phone (the hardware of the phone supports SDXC cards
As I understand it, the phone supports SDXC.
Many 64GB SDXC cards are comming formatted as regular FAT which will work in our phone.
The SDXC standard officially calls out an exFAT filesystem - exFAT will NOT work.
What's with the class on the card never really noticed it what's it mean oh sorry for the thead hijacked...
sent from interspace on my hacked telly...
Class rates the write performance of a card (in MB/sec). So a class 10 card has a write performance of at least 10MB/s (write speed varies depending on the size of data). Typically, cards read much faster than write (on average 2x faster).

Thanks. I read somewhere in another forum that someone was using a 64GB class 10 card formatted as FAT32 and got ~5MB/sec, suggesting that the format slows the card. My current 32GB micro SD gives me also ~5MB/sec (guessing its a class 4/5 without pulling it out), so a 64GB at 5MB/sec would be ok. I will get me one and report back. Just not sure yet which one. Sandisk? Samsung (haven't seen that one online yet).
Look what I just found:
http://www.engadget.com/2012/01/09/sandisk-unveils-worlds-fastest-128gb-sdxc-card-and-new-inand/
Class performance is only measured on a specific test... and can sometimes not be indicative of real-world results.
Sometimes people find that a Class 6 card does better overall than a Class 10, just due to being "better" in real world aspects other than what were tested for the class rating.
The class rating MIGHT only be raw write performance - the format of a card can have a major effect on performance depending on the underlying flash memory. For example, I recall a bunch of 4GB CF cards that got a HORRIFIC performance reputation at work - after further investigation, it turned out the only problem was that Windows defaulted to FAT32 on those cards, but FAT16 on smaller ones. The 4GB card formatted FAT16 was wicked fast.
My current class 2 16GB microSD card can give me 6MB/s write speed when I copy a small to medium sized file over. However, when I copy muiple or much larger files, the speed will eventually drop to 2MB/s. Most cards, especially cheaper ones, use a small cache to speed up the write performance and hide the slower flash memory. When you writes more than the cache can hold, the true performance of the card shows up. That's why a brand named card costs much more than no-name brands of the same class rating.

No, I'm testing it on my PC with 8GB of RAM directly. Don't trust phones for that task
My understanding is that most SD cards has a small block of flash cells that's much faster than rest of the cells. Small data chunks get write into those fast flash cells first before they write into the much slower mass storage cells. So, if you copy a large file into the SD card, you will see the write performance slowly drop as the cache fills up.
Aren't there 64GB cards that are SDHC?

Here are how it works:
SD: up to 2GB --> FAT16 formatted
SDHC: from 4GB up to 32GB ---> FAT32 formatted
SDXC: from 64GB to 2TB ---> exFAT formatted (although some come with FAT32 formatted for compatibility reasons).
Hi guys,
I've did a search on the forums before posting but it seems no ones ansked the question!
Has anybody tried using a 64GB SDXC card via the SD connector?
I've already formatted the card into FAT32 but any data that's written to the card AFTER 30Gb +- cannot be read....although Im able to browse around the file structure.
any ideas guys?
Thanks all!

I've been using a 64gb SanDisk cruiser USB drive since I bought my tab. I know it is not a direct answer to your question, but the thumb drive works fine in the official USB adapter.
I can however see the whole drive in windows, both XP PRO, and Win 7. The drive came pre-formatted FAT32 from SanDisk, entirely one partition, and apparently readable fine on anything I have run across. From what I understand, you should be able to format your card NTFS if you are using pershoot's kernel.
Later,
Jason
USB mass storage watcher in the market will allow you to mount a NTFS drive with stock firmware.
Since the tab only has a OTG USB connector, if the card adaptor supports sdxc then it should work. When you formatted the card, what was it formatted as before? Was it a quick or full format?
Sent from my GT-P7510 using XDA
thanks for the replies guys,
its a PNY 64GB SDXC it originally came in a exFAT format, Ive partitioned in quick format via 2 different programs.
Try a full format. With a large cluster size like 16k.
Sent from my GT-P7510 using XDA
One other thing to mention would be that there are tons of counterfeit SD cards on the market, and unless you got yours from a very reputable seller, there is a chance that it is hacked to report a higher capacity then it has.
The comment you made about being able to navigate the file system, but not open anything past 30g is pretty close to exactly how those counterfeit cards behave. I would be surprised if they used a 32g card as a base for the hacked card, but anything is possible... Anyhow, try H2testW, a google search will turn up download links. It is a free program that will write data to a target device until it fills the device. Then it will attempt to read it back and verify it's contents. After a certain number of mismatches, it will report the memory as likely defective.
This saved my butt a few times on some SDHC card purchases. It takes quite some time to run, especially with large drives, but the big plus here is that it verifies the flash memory before you put it in a device and loose a bunch of data that might be irreplaceable.
Good Luck,
Jason
Ive attempted to do a full format still no luck
The card isnt a knock off, its from a reputable seller and the contents are available to browse ( incl. read write) on a normal desktop computer.... could it just be Android doesnt like 64gb SDXC cards?
I see, I thought you meant that after 30g you could just see the file structure but not access. I'm not sure if it is possible with the tab's USB otg adapter, but if you can format it with the tab, it might work. I know this has worked for people with phones that the manufacturer said was limited to 32g sdhc, phone would not read the full 64g until the people formatted with Android and card in phone.
Other than that, I'd try format ntfs (think only win 7 has this capability for flash) but there are stand alone apps, as well as Linux and parted... Other than that I don't have any other ideas... It might be it doesn't like the xc cards, but I don't think anything electrically changed with the card spec. This is complete speculation, but it seems that if it can handle the 64GB of nand flash in my thumb drive, it ought to be able to deal with the 64GB of nand flash in a sdxc card.
Good luck,
Jason

SDXC is different to SDHC in the same way that SDHC is different to SD.
Does the card reader indicate being able to support SDXC? If not, it's understandable why it is not working as expected and I'm a bit surprised it's partly working.
Are you using the same card reader for the computer with the Galaxy TAB?
At least with SD, they made a clear indication for different memory types / supported sizes. With XD, there was a 512MB limit where older devices would not recognise anything higher but the higher capacity cards were also just called XD.

Ok. Im not a dev so I cant manage this myself. I was digging in the forums and based on what I found I was curious if this is even possible. Fist however im going to list a few facts I have found. Mostly obvious ones.
1. Galaxy Note will not support exFat or NTFS unless you jump threw a few hoops like this
http://forum.xda-developers.com/showthread.php?t=1724078
2. Galaxy S III has native exFat file support only on the stock roms. That makes it based on the stock kernel.
3. exFat or NTFS is a better choice in format simply because to dont run in to the file size limitations as Fat32.
4. exFat or NTFS is much more stable on cards larger than 32gigs for a bunch of technical reasons im not going to get in to.
Soooooooooo . This all started because I have a 64gig Class 1U (Faster than class 10) micro sd card. I was trying to figure out how to get it to work in my Note. The only viable option is to force a format to Fat32 and pray it stays stable. Slows the read wright speed down as well so kinda defeats the purpose of having a fast card.
Is it at all possible to port the Galaxy S III's native exFat file support to the Note? Or is it possable to have a script enable NTFS support at the kernel?
Thoughts, suggestions , and guidance please.
PS: Search button Trolls. The above info was pealed from various forums while setting the search button ablaze. If your gonna mention it then find an answer to this first and make me look like a fool the proper way. Show me what I missed I dare ya lol :silly:

Theres an app with NTFS support by paragon (with OEM exFAT support, not for regular users yet), but like most things, I would definitely prefer a built-in kernel-level support for exFAT...
BTW, exFAT over any other type anyday for me... (windows compatible format at least), blows NTFS out of the water
Say you have the same exact micro SD make, could be sandisk or Samsung, class 10. Has anyone found that even though the 64gb card is usable, but not advertised as compatible that problems have occurred using the 64gb card?
The most important thing is making sure nandroid backups do not get corrupted. Also the larger the card, does it take longer for the media scanner to run?
Sent from my SGH-I777
I think you would be taking a risk using a card not certified as compatible with the device. As for media scanning, it all depends on how much data is actually on the card, but of course it would take longer to scan a larger card (and prolong bootup, as well). I used to have just an 8gb card and noticed a dramatic change in bootup when I went to the 32gb card I now have because I was able to put a lot more of my MP3s and movie files on it.
So would it be accurate to say a nandroid backup is more likely to fail in a galaxy s ii using a 64gb card than a 32gb? And I mean data getting corrupted, md5 errors. Perhaps you remove the card/unmount it then try to later use it for backup.
Sent from my SGH-I777
The problem I have found using cards larger than what's specified compatible is that the OS will try to copy data to a sector outside those on the largest supported card and then when it tries to read them later it can no longer find them because it doesn't recognize sectors beyond the card size limit. It may show the files in a directory structure because of the MBR or filetable reference, but it can't find the actual data because the data sectors are not recognized.
i'm using 32g class 10 and feel good !!! speed average about 10MB/s
I thought the max size supported was 32gb? Man I almost picked up that class 10 16gb Samsung at work (wouldve been $20 for an employee) but it turned out we had to order it which means no discount..

The max size supported is 32gb, but 64gb will work fine in many cases. Some users have reported needing to format the card to use the fat32 file system, others have had it work fine out of the box. I read CWM won't be able to recognize it unless its fat32 however.
