[q] 64gb sdxc - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

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!
3.2 Stock, Samsung Galaxy 10.1 32 GB

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?

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.

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.

[Q] 64GB microsd card for Asus Transformer?

Hi,
Does anybody know if the transformer tablet can take a 64GB microSD card?
Since I ordered 16GB model, it would be nice to make up for lost space and add a 64GB microsd card in there.
first off, thats an SDXC card, NOT a MicroSD, or even an SDHC card.
The Transformer supports up to a 32GB MicroSD (which is the max, but also a rip off at $80+ where as you can get 16GB for $25.
and the keyboard supports SDHC cards to which i think go up to 64GB.
Personally, i'm buying a 16GB class 6 MicroSD and then a 32GB SDHC card for the keyboard for a total of 64GB of storage.

I've read reports that the keyboard dock will support full size SDXC cards but until they arrive in people's hands I'll take that with a pinch of salt.
Yes the official site says that the dock will accept SDXC cards, so in theory it should take up to 2tb cards (when they come out). As stated above, it remains to be seen though.
So what is the largest and fastest card you can put into the tablet itself (not the dock)? And can someone recommend one?

Largest would be 32GB and I would recommend this for its price, capacity and its class-10:

WOW! i actually though that not 2 months ago those were 120$+? and a class 10:O may start to think about it... (but still for this price i think you can have 3 16gb but still....)
thats cool that it'll take the XC cards as well did not know that.
but regardless, thats only the keyboard dock.
The tablet itself will only take up to a 32GB microsd. which currently is a waste of money IMO

And I take it the wintec is doing just fine in the transformer? If so, to be clear, is it the wintec 32gb class 10 micro sdhc that is selling on newegg for $77.49? Sorry for not posting a link, I do not have enough post history to do so yet.

Technically SDXC cards could work, all you need to do is format it to FAT32 and maybe some driver changes to the system, but i cannot verify that since no microsd cards exit yet
http://en.wikipedia.org/wiki/SD_card#SDHC_and_SDXC_compatibility_issues
Electrically and physically SDFC and SDXC are the same, just higher capacity and ExFat is the default file system standard for the new cards
Why the name change and new standard?
Well you can thank Microsoft for that
FAT16/FAT32, which is standard for flash memory supports up to 2 TB
Windows operating systems allow you to format to a max of 32GB
The reason being dates back to Windows 2000
(although versions of Windows NT way before used NTFS, But Windows 2000 was more available to the home user)
FAT32 was common, and microsoft wanted people to use the NTFS file system, so they decided to limit the creation of partition to 32GB for FAT32
Well that has stuck with all future versions of Windows, dont know why
Also Microsoft created ExFat, as a replacement for FAT as a removable storage file system, supports new goodies, and its a Microsoft Patent pending file system
So the SD foundation created the SDXC format because since most people use windows and cannot format their SD cards larger then 32GB why not just create a new standard that supports ExFat by default so people can easily format it
(You can use other formats such as NTFS, EXT, and etc.)
**Note that FAT32 filesystem does suck because it cannot support files larger then 4GB
I probably left a few things out during my ranting

I have the 16GB version in my Transformer. It was in my Evo, partitioned with ext3 for a few months, and I never had a single problem with it. It also performed @ class 10 speeds after applying the sdcardfix zip file.

I know the OP is a bit old by now, but thanks for this. I just purchased it for $41 and some change to replace my 16GB card which my wife will inherit. I'm always flashing custom ROMs and kernels and such and like to keep some other files on there too like music and pics so that they survive full wipes. It isn't too hard to start to fill up 16GB (right now I have 3.3GB free). Now I will have plenty of room to play around with for awhile. I believe I paid about the same or more for the 16GB card at BB, but had to because I had a brick not realising that rooting required the card. Didn't want to pay $90 or so in store for the slow 32GB card they had when they were advertising a class10 32GB online for alot less.

Would this mean that any of the 64 gig cards should work ok?
Or if you guys have links to the specific card you purchased, I can get that one as well..

i use a Sandisk 64GB Class 6 Standard SD in my dock, works like a champ. cant afford a micro 64gb lol
very nice! thx for the info
I use a 64gb SanDisk Micro SDXC card in my Prime and currently have 28.8gb of the 59.46gb available free. I have music, videos and emulator roms on there.
I don't think I will be needing to put a card in the docks sd card slot yet but IF I ever do then another 64gb would be going in
I have a class 10 64GB in the Dock and a class 6 64GB MicroSD in the Prime
I had to reformat them to get them recognized and they have run fine since...
Scored the 64GB SanDisk MicroSD
http://www.buy.com/prod/sandisk-mob...nded-capacity-microsdxc-1-card/226590490.html $110 shipped, got mine a little cheaper on sale.
I run a Pretec 64GB Class 16 SD card in my dock that I bought from either Newegg or Amazon for ~$75 and I am very pleased. I've had it for 5+ weeks now with no trouble and many transfers on/off of it. About 2 weeks ago I formatted it NTFS and I now get write speeds from 16-24 mb per second! I was a bit nervous when I purchased it as I had never really heard of the Pretec brand before but, I have absolutely no complaints. I watch my 720p .mkv movies from it and hardly ever have a stutter. In my Prime run an HP 32gb Class 10 MicroSD and it also functions very well. Both are highly recommended.
I use 2 Sandisk 64gb mobile ultra microsd's in both the tab and dock. I have them both formatted as extFAT due to the size. The tab reads all 59gb's of the micro on both cards.
Format 64GB
Hi,
I am new to the site and the 64gb XC1 class card. I purchased one and tried to reformat it to fat32 and was unable on several systems. I could not get it to be recognized on my phone or the prime. Any special direction on what needs to be done in order to get it accomplished? I updated windows 7 to the required KB fixes and still nothing. Even thou my HP had an XD slot, not sure if that is different than than the XC; which probably is.
Thanks, appreciate any response

Format exFAT or NTFS. Fat32 does not support that size of drive and will also limit you to a maximum single file size of 4gb. Many HD movies can exceed this easily.

Best Buy 64gb sdxc class 6 $79 bucks

Not a bad price at all for a sandisk, hope this hasn't already been posted.
64GB SanDisk SDXC
64gb microsdxc
I went to several best buys all stores were sold out.Ordered online and waiting for it. Has anyone have one on their transformer? If so how does it work?would be awesome to have 96GB on the tablet.Reps at the 3 best buys I went to said they flew off the shelves.and what does the xc mean.Thanks for the post great price..
I've bought one recently on Amazon.co.uk. I was around 45 pounds and comes with SD size adaptor, in which microSD card stucks a bit and it is tricky to take it out. I'll be using SD adaptor from my Samsung card, it is really easy to remove microSD from it.
Card is preformatted as exFat and tablet said that it is corrupted and needs to be reformatted, then stuck on unmounting operation. I'm on AOKP rom, btw.
I was expecting problems with file system and I've tried to reformat it to Fat32 on my PC (Win7 HP x 64) using few tools (HP format and Fat32formatter) but it didn't work either. I've also tried NTFS just in case if AOKP handles it but it didn't. I'm not sure if it depends or rom or kernel.
Then I've searched xda and found some threads with advice to use mobile phone (HTC Sensation or Samsung) to format card. Luckily I own HTC Sensation, so I've put card in mobile and formatted it. After that, card worked on my TF101.
Still it is Fat32 file system so it can't handle large files (over 4GB) but I don't worry about it.
PS. I forgot to mention that after format it comes as 59GB.
So, does it work in the transformer in the MicroSD slot? or do you have to use an adapter and use the SD card slot.
I don't have a dock, so it is plugged directly to tablet via microSD port.
I've mentioned SD adaptor because I've tried to reformat card on my PC at first and I had to use adaptor there.

That's actually wierd because I have 64GB card from sandisc and it's formatted with exfat and works without a problem. But I'm on ARHD 3.2.1, Maybe that's why. Also rouge xm recovery does not recognize exfat so I'm stuck with internal memory only for now.

Sandisk "Ultra" 64gb SDXC (micro SD) card, Class 10, UHS-1

FYI... Sandisk is now selling an "Ultra" 64gb SDXC (micro SD) card that is rated Class 10 and is UHS 1. The "Ultra" tag refers to their class of cards that have 30MB/second read speed (unk. what the write speed is). Sandisk also has an "Extreme Pro" class of cards that have 95MB/second read speed, but the largest "Extreme Pro" in micro SDXC is currently 16gb. If you shop hard, you can find the 64gb "Ultra" SDXC card for less than $60 currently.
It's been previously reported that Razr supports SDXC cards, including 64gb (see this thread).
For anyone who might buy one, a word of caution. Put it in your Razr and format it there first before trying to use it on your PC. I'm not sure whether I received a defective card, or I somehow ruined my card by trying to format it to FAT32 on a Windows machine (using Paragon Partition Manager). I spent hours screwing with it before giving up and returning it to the seller.
I have the same 32gb version in my razr right now and it runs great. I assume the 64gb one wouldn't be any different.
Got mine for $23 on Amazon. Couldn't pass it up for that price.

It depends...
Is your USB adapter USB 2.0?
I typically use the SD Card slot with the adapter provided with the micro SD card.
USB for transfer unless you have a good adapter can be slower.
I use one 32gb class 10, works fine.

Have you tried a HD 1080p recording on your 32gb class 10 card ? , if yes - did you find any difference when you tried the same recording on a class 4 ( assuming 30 fps and standard cache)?
Got my one for a few weeks, phone has never been so slow.
Not faulty (tested the card multiple times) - anyone else having issues? I feel like I have a Galaxy S1. Just weird behaviour - Swype takes forever for k/b to appear, winamp takes forever for thumbnails for albums to appear - just apalling performance from my phone.

I couldn't mount it or format it. My RAZR kept saying it was damaged. So, I formatted it in my PC first and all is well.
If you're under Windows XP, you'll need to have a program to do this. I used EaseUS Partition Master which you can get for free at http://download.cnet.com/EaseUS-Partition-Master-Home-Edition/3000-2248_4-10863346.html.
So far, the card works great and it's nice to have more room for DLC and songs.
I own this card.
It was a pain in the ass to format, but once I formatted it a few times, it worked great.
64gb picked up for like 70$ shipped from ebay. All my Community, Walking Dead and music and SO much more. Couldnt be happier
I just orderd sandisk ultra 16gb and I will probably recieve it next week. I have atm 8gb class 4 card and I want to move all of my stuff from my 8gb card to my 16gb, what is the best way to do it?

You can simply put it in the phone. No need to do anything beforehand. If it requires you to format, the phone will tell you to do so.
I've given up completely on trying to get this to work in my phone. The phone will recognize it as 64GB, but will freeze up on numerous occasions even if I'm not accessing it. Does no one else have the freezing issue? Running Flick 5.0 Tornado
So what's the concensus on this "extreme" cards' performance while in the phone? Are backups faster? Transferring files to/from a dekstop while connected via USB faster?

64gb sd vs 32gb sd reliability and performance in i777?

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.
That's good info, Miami. Definitely makes sense.
