[Q] [JAN 17] [HELP] [REQUEST] NAND Android w/ EXT4 support does not support 16GB SDHC

I have tried several builds but the result is disappointing. None of them can boot when I want to use EXT4 partition for data on it with my large SDHC card (16GB)
My 8GB Class 6 microSDHC runs fine but when I want to use Class 10 16GB card, the system crashes on boot...
I think 15GB FAT32 partition (I created 1GB EXT4 partition at the end of the card) is too large to be seen during Android boot or what?
Do you think it will work when I create only 7GB FAT32 and 9GB EXT4 it will work? Or should I switch the order of partitions (EXT4 first?) (it is not good solution but good for test)
Can someone from cooks help here? Thank you very much.

Firstly, this is the wrong section. There is a Q&A section explicitly for questions like this.
Secondly, I have a 16GB card with exactly this setup (15+1) and it works perfectly. Your card is possibly defective. Grab this little program and test it.

I use a 16GB CLASS 6 SD CARD for a long time.
maybe is something wrong with ur 16GB
and never create a partition bigger than 1.5g for your EXT4
I still guess the problem is your 16gb card..

I am also using a 16GB class 6 micro SDHC with no issues so far.
My partitioning is 14+2 (FAT32+EXT4) and runs like a charm.
I agree with the others, there must be something wrong with your card.

Thank you. I will test it using the program...
THe card otherwise works correctly...no bad clusters, missing files....perhaps the Class 10 is only a advertisement and the card is too slow? (because I heard that if the card is too slow then the system may boot too long and also become unresponsive (force close or wait for main android process etc.)
SO to give a public anti-advert I will reveal that my microSDHC card is KINGSTON CLASS 10

I have the same card kingston 16Go C10 and no pb !
My advice, make your partition (after full format fat32) with CWR (swap 0)

I've been trying everything to get a NAND install using a (brand new) Kingston 16gb class but have had no luck. The same process works on my sandisk 2gb card. I posted the question earlier today for any advice.

I got same problems with my 16 gb class 10 card (adaTA).
The card is 100% error free and on winmo work superfast. Unfortunately when i try to make ext partition on this than is going to work so sloow and with errors.
I have also PQI 8gb class 6, sandisk 8gb class 2 and samsung 16gb class 2 and I have to say that ext partitioned roms work fastest on slowest sandisk!!!
What is going on?

SanDisk 32GB MicroSDHC. no problems with it.
i used gparted livedisc to format 1gb ext4 partition. works great

32 GB ok but what class?

[Q] What is the best format for sd cards

I have a micro sd 16 gb class 2 and micro sd 32 gb class 4, what are the partitions that android will read and what are the advantages of one over another.
My transformer is running prime 1.5 and blades v 16 kernal.
i was using fat 32 until i tried putting a video on it and changing to nfts, does android support an sd card having linux or mac partitions?
the same with app to sd stuff and does that have to be certain partitions or not

Android is Linux so it should be able to support FAT32, FAT, exFAT, ext2, ext3, ext4, NTFS, other stuff..
I would go with FAT32!

fat 32 wont allow a file over 4gb, which is why i want to switch. i tried nfts and ext3 on my sd card and my transformer wouldn't recognize it. The kernel also said nfts support which is weird?

Oh, right! Try FAT32's successor: exFAT! it supports a file of up to 16 exabytes I believe! Try finding an SD card that beat that file system! Plus, it will work for any OS!

How to format 64gb micro sd card to Fat32 to work on SGS3

Hi guys,
I faced a problem with my 64gb. Sandisk micro SD and I solved the issue and I thought about posting the solution here that might help some of you.
so... the issue I faced is how to get TWRP recovery or CWM to mount my Ex sd card.
basically the problem is that the card is formatted in exfat or NTFS and in both ways it won't be recognized by TWRP and the only way to formate it in fat32 is by only one software because windows can not format more than 32gb in Fat32.
and here is how:
first: download EaseUS Partition Master Home Edition from this link http://download.cnet.com/EaseUS-Partition-Master-Home-Edition/3000-2248_4-10863346.html?tag=mncol%3bpop&cdlPid=10982635
Second : Now you can see a list of all of your hard drives. Note the one highlighted in blue on the grid. This is my 64GB MicroSDXC card in my USB Card Reader. Obviously the location of your card in the list may differ dependant on the number of drives in your computer
You’ll need to right-click on the drive in the list representing your 64GB MicroSDXC card and click “Format partition”
Third : You need to select FAT32 for the File System, and 32KB for Cluster Size.
EaseUS doesn’t immediately apply the changes you specify. Instead, it queues them up so that you can review and revise them before you commit to having the program affect those changes. then we need to press the Apply button.
that's it ... now you can enjoy your 64gb MicroSd and you can mount it in TWRP or CWM recovery .
your welcome

It has to be in general section.

I've tried this method, my card became 32GB
Then I put it into my Galaxy Note, it saw it also as 32GB, then I formatted the card with Gnote, then it became 64GB again
I was planning to create two partitions with minitools formatting tool, one was supoosed to be 16 GB FAT32 and the remaning part would be 48GB NTFS, and I was planning to use, Paragon NTFS to mount that NTFS partition on GNOTE.
But because after formatting on PC it became 32 GB I couldn't do that.
Any suggestions ?

thanks so much for this. I just bought a new 64 gb card for my phone and it "corrupted" on me twice. I plugged it in to my comp and it was exFat. Followed the directions here and formatted to fat32. Now I have to copy my files again. I hope this works. Oh and according to my phone, there is no update 4.1.2 for it. I am on 4.0.4 and it cannot find any updates so that doesnt really work for me.

THANK YOU!!
I had been trying to do thiis for 4 hours when i saw ur post! Thanks sooo much..at first i got an error while formatting, but then i quit all other applications as recommended by the software and it woeked perfectly on my HTC Sensation. Thank You Soooo much:laugh::good:

I was looking to format my card to Fat32 so I can use a Paranoid Android Rom. What happens when I want to flash another ROM and the new ROM is a Tochwiz Rom... Will I need to unformat the card or reverse it someway? I'm a newbie to this stuff.

No. Touchwizz roms and aokp/cm10 roms can both read fat32 sd cards. Because exfat is licenced from Microsoft AOKP can't incorporate the drivers needed to get exfat formatted card to work.
Short story is both roms can read/write to fat32 formatted sd cards. Only Touchwizz roms can read/write to exfat formatted cards. Unless you copy a lot of single files over 4GB in size stick with fat32 formatting.

Did you ever find out how to revert back to 64 GB. I am exactly in a similar situation with a 64 GB converted to 32 GB and do not know what to do?

You can still use your card normally. I've done the inverse way (Touchwiz to AOKP) and works too.
The point is: Touchwiz based ROMs have support to FAT32 and exFAT. AOKP ones have support only to FAT32.

That's another point OP have forgotten. Your card reader must support microSDXC cards. Most readers support only microSDHC and these are maximum 32Gb storage. microSDXC has elevated this limit to 2TB. I had to buy myself a new card reader due to that incompatibility.
There's a fragment in Wikipedia which explains this situation:
SDXC cards are pre-formatted with Microsoft's proprietary and patented exFAT file system, which the host device might not support. Since Microsoft does not publish the specifications of exFAT and its use requires a non-free license, many alternative or older operating systems do not support exFAT for technical or legal reasons. The use of exFAT on some SDXC cards may render SDXC unsuitable as a universal exchange medium, as an SDXC card that uses exFAT would not be usable in all host devices. Since the FAT32 file system supports volumes up to the SDXC's maximum theoretical capacity of 2 TB as well, a user could reformat an SDXC card to use FAT32 for greater portability between computers (see below). FAT32-formatted SDXC cards can be used in a host device built for SDHC if the host device can handle 64 GB and larger volumes.

Maximum SD Size

I'm sure this has been asked before.. but if you are running 2.3 or higher.. what is the maximum SD card the phone can take?

I believe a 64 GB card has been reported to work. As my largest is a 16 GB SD card, I can't confirm for sure.
Sent from my Galaxy Nexus using Tapatalk 2

In the original manual I have for the phone says that 32 Gb is the maximum. At the store when I bought it told me to use 16 (as I am) to avoid having a slow phone.

i have a 32 gb card. the issue is that I think Fat32 can only support up to 32 GB.
can you have an ext2 formatted SD card working in the Dinc?

I just tried putting in an 8gb SD that I had reformatted to ext2, the phone doesn't want to mount it. I'm not sure if there is a workaround for this or not. I've been able to use the Easeus Partition Master to reformat a 500gb hard drive in fat32, so that will probably be able to format a 64gb card in a fat32 partition so it can work in a phone. Won't know for sure until someone with a 64gb card can try it though.

It appears your ext2 question is answered below but as for the size limit of FAT32, it's much larger than 32 GB. The largest a file on FAT32 can grow is 4 GB though.
It looks like FAT32 can run 2TB drives so there's no problem there.

That's wrong. Just trying to clarify. I am running a 64g card in my tab 2 10.1" I have it formatted as fat32. It is a Sandisk. I would say to move everything over to your computer and reformat it. Then use the test disk program and make sure it passes. I don't have any lag with songs or data. I use Foldermount with several large data files programs and they run fine.

It's actually half wrong. Because originally our device was released running ICS, which only supports up to 32GB external storage, this is what the spec states. HOWEVER, now it has a Jellybean update it can run 64GB external storage (since Jellybean can support up to 64GB cards).
So to clear this up, if you're still on ICS, you can only have up to 32GB cards. I suggest updating to Jellybean if you want to run 64GB cards. If you are running Jellybean already you need to format the SDXC 64GB card on your PC using the Fat32 format before using on your device.
It's also worth noting that if you are storing files over 4GB or around 4GB on the card it WILL run very, very slow.

Ics also supports 64gb
Worked on Sony Ericsson Xperia arc and Asus tf300
You need to format it in the actual device and as said above file size limit of 4gb and fat 32

Wrong again, well half wrong, 64GB do indeed work on ICS just they have to be formatted to fat32, JB adds support for the native format of 64GB cards.
as for the OP's issue, I use Poweramp and when I first got this tablet I had the occasional skip so what I did was go into its setting and increase the Audio Buffer size.

That's wrong as well.
64 Gb cards are normally formatted using the Microsoft proprietary exFAT file system. Microsoft somehow managed to arm-twist media manufacturers into using exFAT, which only some versions of Linux support.
If you format your 64 Gb or larger card using the free, unencumbered FAT32 file system, it'll work just fine with Android.
exFAT does have some real advantages, as the overhead (wasted space used by filesystem bookeeping) is lower. And exFAT allows very large files (more than 4 Gb.)
So,there's nothing special about 64 Gb cards other than the default filesystem. Reformat using FAT32 and you'll be fine.

Because ICS doesn't support exFAT. Can you kindly find some official documentation stating otherwise? Thanks.
In other words, you're right. And I'm right. You're telling people that they're officially unsupported (which is quite correct), and I'm telling them how to use them,
If we only discussed what was officially supported, xda-developers would be a pretty empty site.
