SanDisk Ultra 64GB microSDXC Class 10 Only $54.51

Found this really nice deal on Amazon.
Just ordered one
http://www.amazon.com/gp/aw/d/B007WTAJTO/ref=redir_mdp_mobile?redirect=true

I'd say be careful. If you check some reviews, I heard when they sell out, they replace it with Class 6.

You don't have to worry if you buy from Amazon. If you buy from a third party make sure it says "fulfilled by Amazon", you'll get super saver shipping and it will be exactly as described.

It's Sold by Amazon and
Fulfilled by Amazon,
so I'm not too worried about it.
If they ship something other than what I ordered, I'll just return the item
I've always had good experiences with Amazon, as long as the Items are Sold by Amazon directly, or if the Seller's Return Policy is the same as Amazon's.
I read through All 12 pages of Amazon reviews.
This Is a Class 10 Card.
The 4th reviewer was only stating his opinion. Every Reviewer (111 of 112) received a Class 10.
And the 4th reviewer most likely also received a Class 10.

I'm actually using this card right now. Ordered it Saturday, got it Wednesday. Works like a champ.
From Amazon, of course. The price was cheaper than ebay, with none of the risk.

Bought this card last night...hope it works in a 16 GB verizon s3...

I would live to get one of these but I'm in Canada. Anyone want to order one for me?

I can't see pics at work if you uploaded a pic with that, but does your computer read it? Does your phone say its corrupt? If everything says it's corrupt you can probably go to control panel -> hardware and do a full format (25/30 minutes). If nothing recognizes it at all, it's bad and you should request a replacement/refund.

had a hard time formatting the very first time. I am going to do a full format now, if that doesnt work, its going back. Thanks for the help.
Tried everything i know how...i am sending it back...thanks

Just received mine, and installed it in my S3.
Working Perfectly
This is what I did:
- I removed my SanDisk 32GB Class 6 card from my S3 after 'Unmounting' it.
- I saved All data on the card to a Folder on my pc
*the 32GB card is FAT32
- I installed the 64GB card into my S3, Formatted it, and Removed it after 'Unmounting' the card.
I transferrerd All data onto my New 64GB Card via my pc
- I installed the 64GB card into my S3 and Everything is Working Fine
*the 64GB card is exFAT
The 64GB card had 59.47GB Usable memory beforing transferring my folders over to it.

Your card arrived in the cardboard/blister packaging?
Don't know what the odds are of getting a defective card, taking into consideration the Seller, packaging, etc. But hopefully your replacement card will have no issue.
Have you tried to install the card into another device, if one is available?

You can but you can't format it using the Windows formatter. I used easeus software to format mine so that the card would be visible in clockwork recovery. exFAT is not supported there. Had a bit of a scare after formatting with the HP utility. Repartitioned in easeus but it would only read on the computer and it would FC system apps on my phone. Figured out that the partition needs to be primary not logical (what easus defaults to for new partitions) to work on the phone. All you have to do is pop the card in the computer, open easeus and format fat32. Don't mess with partitions

I didn't realize that Clockwork didn't read exFAT.
I just did a backup to my Internal storage cause as you say, CWM didn't see the ext. SD card.
I'm gonna reformat the card now.
Thanks.
Is this what I need to use to convert to FAT32?
http://en.kioskea.net/download/download-380-easeus-partition-master
I'm going to do the following:
- format 64GB card in my S3, which will delete all data
- install Easeus onto my pc
- put 64GB card into my pc
- open Easeus Utility, and format 64GB card to FAT32.
- reinstall Folders previously saved on my pc from my 32GB FAT32 card to the newly formatted 64GB card
- install card into my S3, and I should be good to go?
UPDATE:
- Formatted 64GB card to FAT32
- CWM recognizes card
All is well in the neighborhood

[Q] 64GB SD card unformattable in AOSP & AOKP

I have had my GS3 for a little over a month, rooted and had no issues, I installed another rom with no issue. Unfortunately when I tried to install a CM10 or AOKP rom, each say my ext sd card is damaged and needs to be formatted. I try to format, but it hangs and then just quits without completing the task.
I have tried formatting to fat32 on my PC, downloaded EaseUS Disk utility to format, but none seem to work. When I restore back into the previous rom, it still says damaged and then I can format and start over only in that non AOSP/AOKP rom.
I boot into recovery when the AOSP/AOKP roms are loaded and it wont even mount or format in recovery either.
Any ideas?

I think I read somewhere that in CM10/AOKP that it won't read/understand exFat very well.
So, formatting to Fat32 is definitely the way to go.
When I used some other programs it would say the same thing... that my card was damaged and had to be fixed.
I had a heck of a time finding a program that would do it for me on my 64gb sdxc SanDisk card!
But I found a free one called GUI Fat 32 Format that actually worked.
Click this link and it will start to download:
http://www.ridgecrop.demon.co.uk/guiformat.exe
It didn't work immediately, for me at first, but after a few tries it actually worked very well.
I think that once you get it into Fat32 all of your problems will go away. Hope so anyway.:cyclops:
Let us know if it works!

This seems to have corrected the issue, finally

I had a similar issue... I flashed an AOSP ROM on my phone n it corrupted my sd card and wouldn't format. before formatting I went back to a touchwiz ROM and it still said it was a bad sd card and needed to format I ended up formatting my card in my phone and lost all my data. I put music on my sd card and removed the sd card from my phone before flashing another AOSP ROM. After I installed another AOSP ROM I re-inserted the sd card and it again said it was bad and needed to be reformatted...
So my question is...How can you use a 64gb sd card on an AOSP ROM...I'm back on touchwiz for now. Sd card works fine.
Does formatting the sd card in your phone format it to exfat and not fat32?

Wait, so you're saying that AOKP/CM10 don't have the necessary drivers to handle exFAT formatted sd cards?
Do you remember where/how you came upon this information? Was this issue particular to 64gb SDXC cards vs smaller SDHC cards or maybe to certain classes of cards?
I find this shocking, but I can't say it isn't unfounded.
I have a 64gb uhs-1 sandisk card coming from newegg in a few days, so I'm obviously concerned.
Any insight you could provide is greatly appreciated!

Hey guys... after doing some fooling around I've found out some (useful) information for people with 64 gb sd cards...
1. When you format an sd card while its inside your phone it will format it to exFat.... which is fine if you plan on only staying on TW ROMs. This format is not compatible with TWRP Recovery and has given me issues (causing me to loose all my data on my card) just by flashing an AOSP ROM
2. If you use the program posted in the second post(thanks iomega311) you can format your sd card to Fat32 and it will now work on TW ROMs, TWRP, and AOSP ROMs.
Hope this helps for anyone with SD Card Questions/issues.

In my opinion... Never program sd cards on phone... Always use a computer. Especially if you want it done right!!!!

CM 10 which all the AOSP roms are based off does not support exFAT since it is a proprietary format and they don't want any legal trouble. The best way to format a 64GB gard is with GUI formatter

What allocation size did you guys use? Just got my 64GB SDXC and need to format it so that I can use it on CM10.

[Q] 64GB MicroSD can't be formatted

I just got a 64GB Class 10 SDXC card from Sandisk(the sale on Amazon). My GS3 running CM10 reports it as damaged or corrupted. Trying to format it on the phone eds up with a perpetual unmounting notification. My printer says the card is corrupt and two computers (Linux Mint and Mac OS X) will not recognize it at all using a USB adapter. The most success I have had is when I put it in my Atrix 4G(even though it only supports SDHC cards). It got through formatting but the phone locked up immediately after and the card was corrupt upon rebooting. Does anybody know of a solution or should I request a return through Amazon? Thanks in advance!

Gotta format it FAT32 on computer. Windows won't do it. Gotta use a program. I forgot what it's called. Just Google it.

The 64GB microSDXC card comes formatted as exFAT, which isn't supported by AOSP kernels. Using a 3rd party Windows program or a phone that supports exFAT (ie. your Galaxy S3 running a stock/custom Samsung ROM), format the card to FAT32 and it should work properly. You can also try formatting the card to NTFS and using ktoon's test kernel, which has NTFS support.

[Q] sandisk 64gb micro sdxc ultra class 10

I recently bought a brand new sandisk 64gb micro sdxc card for use with my e4gt. When I put it into the phone the phone reads it, but will not give me the option to format it. The only option I have is to mount it, but when doing so it just says it is safe to remove which shows that it is not mounting properly. Should I try buying an sd card reader and formatting it on my computer? Or what else could I do to get it to work? Also, it is running stock leaked GA10 rooted.

I have the same micro sd. For it to work on the phone (for me), I formatted it to fat32 and it worked. Most recently I lost my old card on a trip, bought a new one, I formatted it again to fat32, tossed it in the phone but the phone didn't recognize it, but gave me an option to format it which I did. Then it worked. It might have a bit to do with roms too (I was on stock, then moved to a CM rom)

So you formatted in on your computer? If so which sd card reader did you buy? Could you post a link if possible? And thank you.

Just use any sd adapter and use the format32 gui from Ridgecrop. Roms or builds shouldn't matter once it's properly formatted and mounts.
I have the same Sd card. Sniper and Avatar turned me on to that utility.

128GB Micro SD Card....Do They Work?

Interested in this phone for the specs, and the fact it has root...xposed etc...
Does this phone support and work with 128GB micro sd card.
Was looking at a 32/64gb model in Red.

Hello, this is ASUS_USA. Zenfone 2 model ZE551ML Micro SD Card slot supports up to 64GB

Yes, I am using the Lexar 128 633X in the 551ML 4/64

Here is a picture of the card and the phone.

You should be able to use any sdxc card as the 64gb card is sdxc... If a 512Gb sdxc micro sd card came out you would be able to use this...
And yes I have tested a sandisk 128Gb micro sd card in my xenfone 2...

I am using the Asus Zenfone 2 ZE551ML (4GB RAM, 32GB ROM) and can confirm that a Sandisk 128GB MicroSD card works fine . Mine is formatted with FAT32; i am not sure whether ExFat would be supported as well.

exFat is and OTG USB sticks work fine too... I have a 64Gb OTG card that was working brilliantly with it earlier, shame a friend wanted to borrow it cos I was gonna load it with stuff to do at work tonight...

Looks like Im going to have to pick up a 128gb sd card soon. Thanks for comfirming this since I was wondering the same thing for my Zenphone 2.

I'm running a Patriot 128GB microSDXC myself.

By the way, whats the best type of external microsdcard to use?
Do we need to be choosy in buying??

I always like a good ol' SanDisk

I'm just gonna add a little bit more here, You need a FAT32 formatted sd card for firmware updates if you are doing it manually and haven't rooted yet. The stock recovery won't recognise an exFAT formatted card (which is what most 128gb sd card are formatted) so when you put the update file on your card your card won't be recognised by the recovery.
Rooted with latest TWRP recognises card fine...

In anyone wants to know, I'm using a PNY 128GB card (http://www.amazon.com/gp/product/B00OP2P0ZO?psc=1&redirect=true&ref_=od_aui_detailpages00).
Stock everything. No issues with the ZF2 recognizing the card or accessing.

Seems like a lot are testifying that 128gb is working with their Zenfone 2. My question is will prolonged use of 128gb sd cards have any problem in the future?

Pretty sure you can't have any more info than what's currently available. The phone's only been available for a few months, that's as long as testing with 128GB exFAT or FAT32 will indicate stability for. Card size has no impact on a phone's microsd reader, just like sock size has no bearing on the size of a person's genitalia
FWIW I got a 128GB exFAT a week ago and haven't had any issues. If your phone has issues reading any card, it'll typically have trouble reading every card. Special exception is for devices that software/hardware don't support larger than 32gb, exFAT or Class UHS1 speed cards. Your Zenfone2 supports greater than 32gb, exFAT, and Class UHS1.

Our only choices for backups using ASUS backup are internal device or SD card. If we can only use up to 64GB, some backups might not work if they are larger than that (apps and data) or close to that in size.

With unlocked bootloader and root I have no problem accessing the exFAT 128gb sd card even while using TWRP recovery.
Not sure if the newer roms support exFAT or I have a magical Zenfone 2 but it did an OTA update with the OTA file on the sd card ... No renaming of the file was needed...

My model ZE551ML is not reading exFat 64GB card. Can it be formatted to FAT32 or should be replaced? My PC is only giving me exFAT file system when I try to format it!!!

Mine (I think) is formatted FAT32 and works fine. It's just you cannot have any individual files over 2GB in size.
EDIT: Never mind. I just checked via mount command and it is listed as "texfat". Guess I didn't reformat from when I bought the card.

exFat doesn't seem to be readable at all!! Can it be converted to FAT 32?? Thanks.
