[Q] What is the best format for sd cards - Eee Pad Transformer General

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!

[Q] how is the sd card compatibility in the dock?

hi all
i inserted a 4gb sd card into the dock slot. it was taken straight out of a Canon Powershot S5IS...and it didn't work
havent tried other sd cards
havent checked what format the card is in
i did try rebooting the transformer
did try undocking and then redocking
so hows sd card compatibility? what are your experiences?
i think it only reads it in FAT format.
It reads FAT32 from the miniSD port.
The SD Card Reader on the right side will read FAT and FAT32 formats but it wont read NTFS (for now).
Try putting your SD Card into your pc (if you can), then right click on it and select properties to see how its been formatted.
Mark.

The dock's SD card reader will and does read NTFS. It has since day one on stock or custom kernels............. Guess what it reads SDXC Sd cards too..........
http://forum.xda-developers.com/showthread.php?t=1063470
@OP: I know you know but just in case. If/when you format, you will lose everything on the card.
well thank you guys. seems im the only one with sd card issues lol
im just going to have to try changing formats and try formatting..
i just presumed that a sd card pulled out of an older digicam would be in fat32 haha

I hope it works for you. I did test with 3 cards, two old Sandisk (1GB & 2GB) and a new Sandisk 64GB SDXC. They all worked with FAT32 and NTFS and on stock and custom kernels, but I've seen some people having some problems with certain cards and classes of cards. Please post your findings. Good Luck
I got the following cards:
Transcend Secure Digital 64GB SDXC SDXC, SD 3.0, Class 10
Lexar MicroSDHC Card 32GB w/USB reader Class 10, High speed SDHC card with USB reader
The dock reads the SD card formated to NTFS fine (have not tryed to format it to another filesystem)
But the MicroSD card in the tablett itselfe only reads FAT32, and not exFAT or NTFS.
But there are several of You that got tablets that read Your MicroCD cards that are formated to NTFS?

Allow me:
http://www.tuxera.com/partners/operating-systems/ (NTFS, exFAT and HFS+)
and
http://dlcdnet.asus.com/pub/ASUS/EeePAD/TF101/TF101_Full_0418d.pdf (page 45 "Tuxera software provides support for NTFS format.")
Considering it actually allowed me to read an HFS+ usb stick....
So, unless there is some weird implementation, it should read those file systems also from the SD card reader.
ext3,ext4 is also supported.
I just tried NTFS on the MicroSD and it was a no go for me. I also tried ext3,ext4 (I'm somewhat new linux ) and that didn't work for me either. That could be me lol. So only FAT32 work for me on the MicroSD
On the SDcard. I could only get FAT32 and NTFS to work.
I tried this with stock .9 (3.0.1), 8.4.4.5 and 8.4.4.7 (3.1). Then with Prime 1.4 (3.1).
The cards I tried:
MicroSD: 3 - Sandisk 8GB, 16GB, and 32GB. I think the classes are 4, 4 and 2
SDcards: 3 - Sandisk 1GB, 2GB, and 64GB SDXC
I'm not saying the other filing systems don't work. I'm just posting what i tried.

Good to read that it's not only me that got problems with the MicroSD card not being willing to work witht he NFTS filesystem.
I recon this is something that Asus can fix with an firmwareupdate?
Anyone tried with USB sticks and external harddrives on NTFS file system?
I gues it should not be any dirrefence between A USB stick and an external HD
wow..
im going to give my problem sd card another go this weekend
well the first thing i plugged in was actually my external hdd. this was just a cheap enclosure with fake "VAIO" lettering on it. it relies on a erm...driver(?) called "USB to IDE Bridge" whenever it's plugged into Windows.
worked flawlessly
interesting...
my Sandisk 4gb SDHC simply refuses to work in NTFS
im guessing this is a problem between different card manufacturer and file system combo
but i can't prove it as i don't have too many sd cards lying around.
well at least i'm glad my sd card works now. i shoved it back into the camera formatted as FAT and the cam can use it just fine.
I'm pretty sure I did copy some files over to the MicroSD card when I hade formated it to NTFS before I tryed it on the TF
Not sure now tho so I will do a new test.
But if I am correct it got nothing to do with the card and the filesystem, rather with the TF and filesystems on different card-slots wich I find strange that they let it read one filesystem in one place and not in another place on the tablett.

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

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.

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.

[Q] Doesn't read Ext4 neither NTFS for the sdcard, wtf?

Ok, android is supposed to be just fine with Ext and NTFS right?
Well i've got S4, kitkat 4.4.2 and 64GB original super fast microsd card and guess what, i formatted it first Ext4 then NTFS because i needed more than 4GB files and for both it says "SD card is blank or has unsupported filesystem."
both times formatted under linux desktop PC
the default formatting from the phone seems to be either FAT or exfat but files over 4GB can't be written. (exfat is supposed to do over 4gb right?)
So, what i'm doing wrong?

Official Galaxy S4 doesnt support NTFS (not sure about Ext4). but there are some custom kernels that can deal with NTFS.
I found this on wikipedia:
exFat advantages: File size limit of 16 EiB–1 byte (limited by volume size), raised from 4 GiB−1 byte in a standard FAT32 filesystem.
so I guess yes it can handle files more than 4GBs, I haven't tried it myself.
Use the official SD formatter tool, it formats cards with 64 GB and larger using the exfat system.
just google: official SD formatter

well it's not, thanks for getting the thread in the wrong direction though!
so does the default bult-in android formatting do FAT or exFAT? It doesn't seem to be possible to tell from the phone?
So, seems like the only way forward is to format it in exFAT?

I am pretty sure it will only format in the style it was originally eg. Original setup of fat32 it will format fat32, if EXfat it will format EXfat.
Ext,1, 2, 3, 4 are all native to android (Linux) so ext4 shouldn't be an issue.
When I formatted my 64Gb card sd formatter did not format it to EXfat I had to do it manually. Please not that windows Xp does not directly support EXfat you need to manually install a patch and then manually format the sd card via cmd window
You'll have to confirm the command but it's something like
Format x: /fs:exfat
This is what I had to do on my old Xp box to do the job.

formatted it to exfat and it works now
so for anyone else that wonders here is the summary of what I found
the android on Samsung S4 reads only FAT and exFAT on the SD card.
NTFS and Ext4 it does NOT recognize.
by default it formats FAT
I had to format it exfat on a PC
works now, still haven't tried with files over 4GB but shouldn't be a problem

Micro SD card wont be mounted by Samsung Tab a6

So I have a Samsung Tab a6 7 T280 wifi and I've inserted a MicroSD card (128GB). I've done this with the stock os first and I just got the message card can be removed safely. and it wouldn't let me mount it.
Now I've installed the Tinker V5.1 Stock Rom over it and it still happens. (wanted a faster os on it).
I can reformat the card with twrp to be ext4 or exFAT and it doesn't change a single thing. if I insert the sd card I get a quick preparing card and then instantly the message card can be safely removed. clicking on mount sd card in storage from settings doesn't do anything except prompt same message.
I'd try a different sdcard.
Okay, so I hope I can help, I have the SM-T280, I do not use Tinker ROM, instead I debloated my stock ROM and use an SPA kernel by @_mone. If you're trying to extend storage to your tablet, you'll need to use a PC to partition the SD card two PRIMARY partitions. I used on Windows MiniTool Partition Wizard (free), and I used a FAT32 partition and an ext2 partition. With the stock ROM/kernel I had problems using ext4 or extFAT which didn't make sense to me but it is what it is, and I used the app Apps2SD to handle all the work.
The main thing, you need to make sure your SD card has TWO (2) PRIMARY partitions.
Good luck.

With the stock ROM/kernel I had problems using ext4 or extFAT which didn't make sense to me but it is what it is, and I used the app Apps2SD to handle all the work.
The main thing, you need to make sure your SD card has TWO (2) PRIMARY partitions.
Good luck.

What about the Sizes? As in one partition 60 GB the other one also 60 GB ? Or the fat32 partition 1 GB and the ext2 the rest?

FAT32 is not for large capacity storage. Use exFat. There isn't much point in having such a large ext2 partition. It's incompatible with media transfer protocols unless you use a Linux system.
This device fully supports exFAT. I use a 64gb sdcard no issues.

I wouldn't think so, I'm sure it supports 128gb cards.
Just partition it into to halves. First partition exfat. Leave the other unformatted and see what happens.

partitioned into a 40 GB exFAT partition and left rest unpartitioned. Didn't change anything. if I pop it in the tablet I get a short preparing sd card notification then immediately an SD card safe to remove notification...
I'm really confused by this. The tablet is new so I doubt that it's broken but I don't know. Do you know if there's a way to check any kind of logs on Android like dmesg on Linux as an example to see what happens with the sd card?

It's best just try out another card to rule out the card.

Nobody can lend one for a few minutes? Or try the card in someone else device?

So I have a Samsung Tab a6 7 T280 wifi and I've inserted a MicroSD card (128GB). I've done this with the stock os first and I just got the message card can be removed safely. and it wouldn't let me mount it.
Now I've installed the Tinker V5.1 Stock Rom over it and it still happens. (wanted a faster os on it).
I can reformat the card with twrp to be ext4 or exFAT and it doesn't change a single thing. if I insert the sd card I get a quick preparing card and then instantly the message card can be safely removed. clicking on mount sd card in storage from settings doesn't do anything except prompt same message.

According to Samsung, the T280 will support a 256gb SD card BUT I know from experience that SD cards over 32gb can be VERY touchy. If you use a PC to remove all of the partition and then let the tablet try to do its own formatting and it still doesn't work, I'd say you have an incompatible SD card. That doesn't mean the card is bad but that it just won't work in the T280.
As an example, a Samsung EVO+ card (which can be found on eBay for $30) will probably work while a "no name" card from China, probably won't.

I always use Samsung EVO cards and they always work perfectly. Price per GB they are very reasonable too.
