[ME7 sd card format ??s - Verizon Samsung Galaxy S 4

Currently using a Samsung 64gb micro card formatted fat32 - questions
(1) Does it need to be formatted exfat to take advantage of the TW ME7 updated ROMs? and if so,
(2) Will I still be able to access non TW ROMs with an exfat formatted card? Lastly
(3) Any advantage having a sd-ext partition? Used this with apps2sd pre S4
Tried searching - honestly couldn't find direct answers

Are you currently on MDK and plan to run ME7 based custom ROM's? If so then you can do custom ROM's. I would format your 64GB card to exFAT anyways given the fact that it supports larger file sizes like movies, etc. I don't see why you wouldn't be able to access the exFAT card with any ROM since I have stock TW ME7 rooted and my card is a Samsung 64GB exFAT format. I hope that helps some.

Raptor -
Tried some ME7 Rom's but they seemed not to be moving the apps to the sd card correctly - when I tried to move them manually, I got a "unable to move - card full" error msg.
I thought perhaps this was because of the fat32 format.
Also like to go back and forth between TW and AOSP Rom's and I thought I read that AOSP kernels don't support exfat????? Also need to check that the recovery I'm using (OUDHs CWM 1.0.3.5) supports exfat. I recall being unable to get it to recognize my card until it was formatted fat32.
Thanks for the reply!

I wonder if there is something in how Samsung wrote that ability into the ROM and the devs may be having an issue with finding the right hooks.

Could be - I guess I could back up my card, reformat exfat, and give it go. Unfortunately, I'd have to switch recoveries - Shabbypenguin's recovery does not support exfat. Probably give TWRP a go.......

I am not familliar with Shabbypenuin's recovery tool, but TWRP has been awesome for me on the last several Android phones. I would give that a go.

It has more to do with the Kernel than the actual ROM. Most custom kernels are now supporting ExFat. The only one I have tried lately that doesn't is Elites Kernel but I am sure that will change soon.

Formatting exfat to fat32

If you have been having issue with exfat card even after formatting it to fat32 this is probably the solution for you
The 64gb exfat card i have never worked on custom roms no matter what software i used to format it to fat32.
But finally it worked with this one software, Just make sure you follow the instruction correctly.
http://software-files-a.cnet.com/s/...&pid=12572695&psid=10863346&&fileName=epm.exe
First use easeus to delete the partion in 64 gb card.
then Click Start menu, select Run and enter diskmgmt.msc
You need to find the disk with unallocated space. Right click on it and select "New Partition" and follow these steps, clicking "Next"
Enter the maximum size for the Partition Size
Choose assign a drive letter. I used F:
Select "Do not Format this partition"
Click Finish
Now you have a drive letter, this is what we will pass to the formatter
http://www.ridgecrop.demon.co.uk/download/fat32format.zip
Now download a copy of fat32format. Extract the EXE file to C:\
Click Start->Run and enter cmd (as admin)
type this - C:\fat32format f:
enter y to continue
Now the sd card should work on phone.

An easier alternative which doesn't require CMD or the use of multiple tools is HP Usb Format Utility:

If it works then sure. i already used 3 recommended softwares all failed so i dont know if this will work.
Thanks for this guide
I always format and re-partition in Linux ...
I always format and re-partition in Linux ... and currently all my large microSD cards have been re-partitioned with the following layout:
- free space (4 MB on 32GB, 16 MB on 64GB - since that's how those came from factory )
- main partition (primary partition 1 - I format that as Fat32 in Linux but then I go to Win7 and re-format to exFat; exFat works perfectly in Android 4.x from Samsung (and good mods) and the CWM recovery from CrisKelo ROM can work just perfectly with exFat when doing backup/restore; other (even newer) CWM versions/alternatives might NOT be OK with exFAT or stuff over 32GB!
- 512 MB Linux swap (primary partition 2) - this gets mounted by special mods that give the kernel virtual memory
- free space at the end (at least 4 MB on 32GB, at least 16 MB on 64GB)!
The only drawback is that at this moment there is no program (on PC or phone) that can resize exFAT - so you need to reformat! That is in contrast to NTFS / FAT32 / ext2 / ext3 / ext4 - which can all be resized perfectly - and IMHO NTFS could be a better option that exFAT (for journaling, even if I do not write that much anyway), but unfortunately there is no serious support for it on CWM; ext3/ext4 could also be even better from the Linux standpoint (but not for the usual Windows user that might have problems reading it) - but again is (surprisingly) not so supported by either CWM nor most ROMs
Just got new Sandisk 64GB cards and was having a heck of a time getting them to play nice with Paranoid Android, this guide was simple, painless and most of all, effective. Thank you much for posting this information.
Works with cyanogenmod nightly 2013-02-17 and ubuntu
So I have tried it out and it worked.

Thank you!! Was wondering what I had done wrong with a custom ROM not reading the 64Gb card I had, now it does: )
great to see i helped some people.
ok so software to erase partition is called EaseUS incase this link gets broken in future just google, if im late with reply again in future.

Just wanted to say THANKS
I have been trying to get my 64GB working for days after install wicked rom 5.1 for my Samsung S4, noting worked till I found this post GREAT work and thanks so much!!!!
YOU RULE!
Thanks!! I have only been able to get my Scan Disk Ultra 64G card to work with Perseus kernel and would have to flash it to all Roms then use a hack to swap the internal to get it to work. It was a Pain in the ass and limited my Kernel usage. THANK YOU SO MUCH WHAT A USEFUL POST!! Stick to this plan it works. I have yet to see any other solution. I been dealing with this problem since I had my Galaxy note2 almost a year now.
PS do not use that crappy HP USB format 2.2 whatever program some guy suggested a bunch of malwar garbage I cant get off my computer now THANKS BUDDY Crawl back under a rock which you came.
Thanks for the wonderful help everyone who got it working

i have no idea the swap system, as stock, it already has driver for ex fat but since you changed some stuff it might have ruined that driver.
try your card on another phone with stock rom and same android version. if it works then you dont need to change sd card format, just reinstall ROM on your phone.

CWM Recovery and External SD card... still no go

Hi all,
I've been rooting Android phones (mostly Samsung) and installing CWM etc for as long as one has been able to. This is the first time I've had any major issues.
Issue being, no matter which CWM I install that states it supports external SD on i9300, I still can't install from zip on ext sd, or backup too it, or mount it!!!
Everyone else seems to be able to fine, but for some reason for me, following the same instructions step by step (tripple checked just to be sure) I cannot.
Now I did initially root the device relatively early on in the development stages for it, and installed a criskello rom (v6) about a month ago. Other than that, I've not played around with anything at all. Today I decided I'd try to install a new rom which I'd saved on the device to the external SD. But no, the CWM I had (6.0.1.0 I think) couldn't read ext sd.
Thus, I installed CWM 6.0.1.2 via Odin (following instructions found here: http://forum.xda-developers.com/showthread.php?t=1719744 )
But apparently for some crappy reason I have to be the odd one out, for whom it refuses to work!
Now, just to be sure, i've tried multiple SD cards, all just basic fat format, even reformated them all on the device itself. But nope, it just refuses to work for me!!!
Anyone got any suggestions or am I just doomed to internal memory only?
I'd REALLY like to be able to backup my device before trying new roms
This problem nevf happened to me. I can restore any backup ive saved.
Maybe its a crisckeloRom related problem.

CWM 6 and onwards is known to not play well with external SD's, despite what they say, since the layout is a little bit different in Samsung phones. Try flashing Chainfire's CF-root package, which will provide you with root (of course) and CWM 5, which works well with external SD's. You have my guarantee.
BUT! If your SD card is somehow damaged, nothing will read it properly. Make sure it actually works, and that is has a format your phone understands:
32 GB and up, and running stock Samsung = exFAT
32 GB and up, and running an AOSP ROM = FAT32
Anything less than 32GB = FAT32

Hey,
I have the same issue as fr0dzy. I'm ran Chainfire's CF-root package with CWM 5.5.0.4 and i can't use my ext-sdcard in recovery (to install zips + nandroid backup/restore). My ext is a 64gb card formatted to FAT32 but i can use it when i boot my rom.
Any suggestions would be really appreciated. Thanks.

I'm on a SGS2 Epic4g Touch- same issue. Rooting it everything runs fine, after installing CWM Agat Recovery through mobile Odin I lose access to all apps on Ext SD, something is definitely not playing right with the card. Have you found a work around?
---------- Post added at 10:07 PM ---------- Previous post was at 09:55 PM ----------
This is my first time rooting and running CWM--- is this issue with phones that have both an Ext SD and a internal MMC partition labeled SD? Thanks for any help, guys!
Solved for me!

This last piece of text solved my problem, thank you! I formatted my 2 GB card as FAT32 and installed a custom ROM (4.1.2 Stock) to recover from a broken Ubuntu Touch ROM.
It was a relief!

[Q] extSD woes.

Whenever I flash a ROM onto my I9300 the extSD card will not mount. According to whatever ROM I use the card cannot be read or is corrupt. It works fine in stock JB, however when I restore the device to stock JB it then states the card needs formatting and I have to go through the process of chucking all my music back onto the card after I format (which I'm doing right now).
The card I'm using is a Sandisk Ultra 64GB Class 10. I'm able to make backups and restore from them on the card itself through PhilZ Touch as CWM wouldn't read the card either and some other users suggest I try PhilZ recovery as they've had similar problems. Has anyone else had this problem and is willing to offer a solution? If so what card do you use?
I've heard flashing back to ICS which will write a different mount code than the one JB writes to a device, and somehow this will fix future mounting problems. I don't know how much of this is true but you can read the article here: http://checkrom.com/threads/cant-mount-internal-sd-card.994/
non Sammy based Roms only support fat32

Kernels with exFAT?

I have a 64 GB SD card on my S4. Thankfully it is working with TWRP which now has support for exFAT.
Are there any custom kernels for the Vz S4 that support exFAT?
Since I don't have any files bigger than 4GB I may downgrade the file structure to FAT32 if that is the only way to use a custom kernel on my S4.

I'm interested in this as well...only one I'm aware of so far is by Ktoonsez, in this thread: http://forum.xda-developers.com/showthread.php?t=2294083.
Here's what I got from the kernel dev, Ktoonsez:

Faux is still saying on his kernel thread says that he provide exFAT support due to Samsung's licensing of MS proprietary exFAT format, which hasn't been released as it isn't open source. How was that gotten around on this kernel? Thanks...
Reply from Ktoonsez: A developer named Talustus wrote one from scratch. It work for 90% of the people I would say, some cheapy SDcards seem to have trouble, Samsung cards will work 100% of the time. The exFAT card must be in the phone upon boot up and the exfat partition must be on partition 0 or 1 for my code to pick up on it. To get best chance of success, format the card using Windows 7 or 8 for exFAT, that will guarantee the whole card will be formatted to exFAT on partition 0

I've also asked on the Chronic kernel thread here:
http://forum.xda-developers.com/showthread.php?t=2319243
Faux's kernel does not support exFAT.

Roms not recognizing SD card...

Had this problem with Pie roms as well, but settled on Bootleggers, wasn't an issue with that. Have been playing around with the Q roms now, and am seeing it again with all but Havoc so far. Device is US998, and card is formatted ext4. With most of the roms, it says "card not supported" and gives me the option to format it. In addition to not feeling like shuffling around 64 gb of data, I'm not sure what format it will format it to (this is for media storage, not internal). Definitely don't want exFat, as I've had a bunch of problems in the past with the partition table getting corrupted and needing a windows box to fix (can't be done in linux). Was hoping there was a kernel fix for this. I've tried a couple without success...
Bump... Anyone?

Don't really have anything to add other than, I bother to shuffle the data if it's a rom I want to use. It seems many of the aosp based roms format it to 'fuse' of some kind. Don't think there's any other option but to use what's built into the rom.
cheers
There isn't enough info provided in the OP, so I have to ask: Is the rom designed to support ext4? Not all roms are... Android doesn't natively support it, from what I'm reading. You have to do something to add support for it (and/or you may still need to manually mount it via root). I also read that CM added this support to their releases...
Some info on how to mount manually, and other related questions: https://android.stackexchange.com/q...-system-for-microsd-cards-in-stock-or-non-lin
Either use ROMs that support Ext4 like Lineage OS and a few others or change your sd card to a different format
Also changing the kernel also affects ext4 compatibility
