So I have a 16gig SD Card that I partitioned using gParted, (I was in the process of trying to either dual-boot android ROM's or get a linux OS to boot), anyways it had been this way for awhile and no problems until yesterday. I started using boot manager and after it supposedly installed Evo-Fresh ROM (this would have been booting from SD) I rebooted and it froze so I had to hard reset.
Now I can't recognize this SD card on my phone, though my 2gig SD is fine. But when I connect via USB and mount the device my computer picks up only the FAT32 partition that I had setup, not the EXT4/SWAP extension. I know I need to reformat the entire SD Card, so my question is this.
Can I reformat the SD card somehow on my phone (via terminal, maybe?) or something along these lines so that my phone will read the 16gig SD Card again?
i think the free Paragon App will work with ext4.

elsewise, fire up gparted on your linux box and use that.
You could format it in amonra. It has a pretty good SD format utility.
Windows wont ever see the other partitions nativly

I know that external storage of SD card is limited to Fat 32 and the max size is around 4 GB. What about internal storage? Can I transfer a 6 - 8 GB movie file onto the internal storage of the 7.7 ?
I have the Playbook and I can certainly put a 6-8 GB movie in it.
I saw a guy put 10GB mkv into /SDCARD
easy
$su
# dd if=/dev/zero of=/sdcard/blob
wait a few seconds and
ctrl+c

to overcome the fat32 limitation you can format the sdcard to EXT4 and then copy anysize you want to it
all our phones by default can read linux partitions and fat partitions
if you are running Linux as your desktop PC you would not have any problem copying & pasting files to and from the phone
if you are a windows guy, just install the add-on for windows to read Ext2 partitions

thats a shell commands to create a file for the time you wait... it should create a very large file very quickly, so you will see if it handles big files or not

Eeeexcelent!! I shall have to get an EXT2/3/4 driver for my Win7 box and re-format my 64GB SD!
or just install linux in a virtual box inside windows
then use the VM USB pass through so when you plug it into the PC it will automatically mount on the virtual Linux box

So, using Ext2 volume manager, when I select a volume and want to change the partition type, A) will that essentially re-format the disk, and B) which one is ext4? I don't see that...

Please help.
After I run the above program, I don't know what to do next.
All I want to do is able to transfer my 6 GB .mkv movie file to my SD card so that I can either view it on my Galaxy Note or the Galaxy Tab 7.7.
How do I go about doing this? Is there a simple tutorial guide to using the above application? Do I use it to format my micro SD card? Will it work for a 64 GB card?
The internal galaxy tab 7.7 can take any kinf of file, it dont have de 4gb limitation, but the external sdcard is not readable if formatted in ext4, i have try it and the tab say that the sd is corrupted. I repeat GALAXY TAB 7.7 WITH HONEYCOMB CAN`T READ EXT4 FORMATTED MICRO SD

You need use "drive mount" to mount a ext4-formatted sd card.
You can get it from android market.It's free apk.
Here are some of my experience:
1:I use gparted live cd to format my sd card.
2:ext2fsd as windows ext driver.
3:"Drive mount" to mount ext4-formatted sd card on tab 7.7.
What is the difference between EXT2 and EXT4 ? Which one should I formated into in order to be able to put 6 GB video file on the microSD card?

I am writing this n00b friendly howto for anybody who will encounter similar problem that I had, since I couldn't find much info how to solve it on this forum.
Recently I have flashed CM9 and later CM10 preview on my Galaxy S3 I9300 with 64 GB Sandisk SDXC card. The card was formatted in Samsung stock ROM, so naturally, it was formatted as exFAT. CM9 and CM10 reported it as "damaged SD card", but this was expected, since open source AOSP ROMs do not support exFAT. However, when restored to original stock ROM via CWM recovery, the stock ROM was showing "damaged SD card" error, too! Not sure why this has happened - the only info I found was someone mentioning that "CM9 is known to do this on exFAT cards" on this forum.
Connecting the card (via adapter and card reader) to computer didn't help - it showed as a RAW partition, Windows was asking to format it and even reported incorrect size. Trying about 7 different open source and commercial recovery tools did not help. However, if booted to recovery mode, CWM could see the card just perfectly!
So this is how to get the data back:
1. Boot to CWM recovery mode (power off the phone, then hold Volume Up-Home-Power buttons for 5 sec)
2. When in CWM recovery mode, connect phone via USB to computer. The phone should be recognized and drivers installed (if not already).
Note: I had problems with Windows recognizing the phone in recovery mode on some PCs (only 1 out of 3 worked, actually). To solve this, installed drivers from Samsung Galaxy S3 Toolkit (first step after toolkit installation) and problem gone: http://forum.xda-developers.com/showthread.php?t=1703488
3. Run adb command (from Android SDK platform tools) to ensure that the phone is visible to operating system - it should show serial number of the device and "recovery" next to it:
adb.exe devices
4. Browse the phone to find the location of sdcard (mine was /sdcard):
adb.exe shell
Note: when first time connected to phone via "adb.exe shell", running "ls" in /sdcard directory came out empty. Had to "exit" from shell and do "adb.exe shell" again.
5. Pull the files from your device using "adb.exe pull" command:
adb.exe pull /sdcard c:\temp
replace /sdcard with your sdcard directory on the phone (if different) and c:\temp with other folder on your PC, if you wish.
That's it! After files are copied, reboot to stock ROM and reformat the card. You can now copy all data back to it from your PC!
Now I'm trying to find a way to format the card to FAT32. Seems not so straightforward with 64GB cards!
Sincerely,
satanxda
Man! pity I didn't read this before I formatted my "damaged" card ... good to know there's solution for future

I had the same problem. From stock went to CM10, exFat got corrupted and then went back to Stock still external storage card showed as damaged.
I took the SD card out and put in adapter and then connected to PC. Then from command prompt ran chkdsk <Drive_Letter:> /f and it fixed the errors without me copying the files to PC.
Hope this helps.
And to format 64GB sd card from exFAT to FAT32, use guiformat tool or EaseUS partition master. I have formatted my card to FAT32 using EaseUS partition master.

With this problem you can restore data in more easily way.
Insert your SDcard in CardReader, connect to PC, run Command line (cmd) and type:
chkdsk X: /f ,
where X is your card volume name. After operations is complete, you can use you card again and NO data had been lost.
Sorry for my bad english.

Tried it before posting this howto, but EaseUS didn't see the card at all. Windows disk manager in the meantime reported incorrect size (27 GB for a 64 GB card) and when formatted with guiformat I got a 27 GB partition. Could be a problem with card reader - will try another one as soon as I get my hands on one ;]
mahendra1020, magicm3n: in my case using chkdsk was not possible, since Windows showed the SD card as a disk with not formatted RAW partition (suggested to format it). To run chkdsk, partition type must be recognized.
And by the way, thanks everyone for comments and suggestions!

Yeah even in my case windows showed sd card as not formatted but chkdsk still works.
Try /f instead of /r as arguments for chkdsk.
Are u formatting as fat or fat32? For me both the tool worked.

Probably you are right. Checkdisk button was disabled for me when right-clicking->Properties on the drive, but anyway Windows was reporting wrong size of the card, so I didn't want to risk forcing repairing and didn't invest too much time to that. But as I said, maybe it's the problem of my quite old SD card reader
By the way, successfully formatted from exFAT to FAT32 by using this Android tweak to mount the SD card as USB Mass Storage device on PC (so basically turning the phone itself into a card reader) and formatting in Windows with guiformat:

And did you get CM10 to read all of the 64 gigabytes?
For me CM cannot read the SD card over 32 gb.
Formatted my 64gb SDCard using EASEUS Partition Master to FAT32.
CM9 recognizes all the 59GB+, reads and writes on the card just fine. Didn't install CM10 yet, so don't know if that will work...
FWIW; the Chkdsk /f command did fix mine, and just as well, cause nothing I did (on multiple machines) could get the darn thing to mount in CWM.
yep, chkdsk does fix my 16g exFat card, and it works back just fine now. and before, i tried the CWM way twice, nothing i could pull up, os hints "remote object '/sdcard' not a file or directory"
I've had the same issue, and am really struggling to get anywhere at all with it...
I tried the method in the first post, but running ls on /extSdCard just gives an empty directory...
When I mount it in a reader in windows, it reports zero size and a 'please insert disc into Removable Disc (E: )' when I try and open it...
Even when I just threw my hands up and said 'ok phone, format it' it just says 'unmounting SD card' and then just backs into the normal screen.
At my wits end with this, I suspect the card might be fried, but want to get in if possible as it has my only stock backup!

hmm, well storage isn't part of the structure when is run ls after using 'adb.exe shell'
tried it anyway, get 'can't cd to /storage/extSdCard'
interestingly, when I try and get into just the 'sdcard', which I guess is just the internal storage?
I run 'cd sdcard' and the folder that I get into is /data/media
this is confusing, anybody any ideas?

Please add this simple info to the OP!
P.S.
Windows 7 said the volume is in use and if I wanted to dismount it before it would allow to continue checking/fixing it. But at the end it worked perfectly!
Thank you very much! I had so much stuff on this card that I haven't backed up yet..phew
Thank you for this guide. Help me get all my data of my "Damaged" 64GB sdxc card
I have the same issue. Flashed CM10 M2 on my tmobile S3, got the error that SD card is damaged, restored stock image from backup, and I'm still getting the bad SD card error. I'm using CWM 6.0.1.2 and mounting the external SD failed. I don't see the contents when I connect through ADB. Mounting sdcard from CWM mounts /sdcard but that is the internal storage which is not what I want. I also tried connecting the card to my laptop running XP using a micro-SD card reader and running chkdsk but that reported the disk as a RAW partition. Any ideas on what else I can do to copy files off of the card?
The method mentioned in OP worked for me, using a macbook air with mountain lion and android sdk for adb installed.
After mounting the external sdcard in cwm and copying the files via adb I partitioned the sdcard (sandisk 64gb sdhx) with the inbuild harddiskmanager in mountain lion. You have to choose FAT (MS-DOS), it will choose fat32 automatically. After partitioning and formating the sdcard the card is recognized under cm10 and samsung firmwares.
OSX has no 32gb limit on fat32.
I have accidentally formatted my SD card in ext3 file system mode and now my phone cannot read it.Even when i connect the phone to the computer in usb memory card mode...the sd card is not shown in the computer. So i am not being able to format it again.Please tell me how to reformat it back to fat32 ....
Use EASEUS Partition Master, it will read your SD card in EXT3 format and will allow you to manage / format it!
open disk management (start->run->diskmgmt.msc) and erase your ext3 partition (doable in windows)
If you have any trouble doing this while the card is in your phone, you can also remove it and use an USB Card Reader.
But as said before, you just have to change the unit type to get it working again.
Good luck.

You can use a USB Card reader and this software: "hp disk storage format tool".

Ok really? Amazon blocked file support for ExFat? Is there a way around this at all? I have a 64 GB I was planning to put some movies on for my next flight. But the 4 GB file size limit of Fat32 is hampering my plans...
Installed the Play store following the guide here. Boy - I'd love to get AOSP or something on here but that isn't looking so good right yet. Anyway - any tips or tricks to get movies going would be appreciated.
Regards
I use exFAT/NTFS for USB by Paragon Software from Playstore (actually I downloaded it from apkpure first to avoid the store) to manage my movies on NTFS formatted HDDs. The settings section of the app shows I can access NTFS, exFAT, HFS+, FAT32, extFS.
Actually there was a limited number to mount my drive for free and when it was over I had to pay a small fee (I hope it is not something regularly, have to check again) and register via my Google account which meant I had go install Playstore to get access to my Google account on my Fire HD 10.
It works fine for me. Use it with Total Commander. I tried to find a solution first from Amazon Appstore but failed. I extended the Fire HD 10 internal memory btw with a 400GB SanDisk MC which is ext4 formatted with no relevant file size limit for movie files.
Let me know if it works for you. My next project is to do the same with my Fire TV Cube.
BR Martin
Hey Submonte - thanks for the idea. I downloaded paragon but I think it is angled toward USB mounted drives like the external hdd you mentioned. But slipping the micro SD card in - doesn't do anything.
Hmm...
Ah I see. You want to use your microSD card as Portable memory. I excluded that option for me (but never trying the exFAT app in this way), got a Tutuo USB C OTG adapter (micro SD and SD and USB A) and set the memory option of my Fire HD 10 for the SanDisk card to internal memory. So I copy movies from external micro SD or HDD (mounted by the Paragon USB app) to the extended internal memory (Android: Adoptable memory). Of course in this case I cannot take out the card and put it into a laptop or so, it is not portable, internally formatted as ext 4, but has no file size limit.
Okay - I might see a ray of hope here... So I get "Adopted Storage"... So if I power off the tab - can I remove it - mount as ext4 on my linux laptop and copy over all the files and then power it back up? If so - how crazy is that - it won't recognize it when I format it in my laptop as ext4...
I read somewhere it is a big FU from Amazon on no way they want you watching HD movies with out buying them from Amazon. Thought that was ranting - but if it supports ext4 "internally" but purposely blocks it in this way??
Anyway - thanks for the reply. Gonna make some tests...
Adopting the storage in Android/Fire OS settings means the micro SD will be reformatted from exFAT or FAT32 to ext4 (or f2fs eventually in other cases - Samsung) and tied to the particular device (the Fire HD 10 in your case) by a key stored in the device. The internal built in storage (eg 64GB in my HD 10) will be extended and the micro SD memory an integrated part of it. Provided you unmount the card and remount it the device will recognize it again eventually, but no warranty. It is not dedicated to be portable even if you format it ext4 on your linux pc. Therefore I chose the way I described.
By the way I use Prime Video on this and other devices (and many other Amazon services) and use also their offers and buy movies for 50% off or so. Their Echos and so on are great. It is their right to restrict the interfaces in their devices (Still we get a lot for our money). However I wanted to use my tablet universally and do what I want with it. I am a supporter of open standards since my first steps in computing during 70s and 80s, hard and soft. It remained as a hobby. Let me know if you make progress. BR Martin
No joy. I inserted another 64GB SD into the Fire HD 10 and told it to use it as internal
Using the USB cable I copied an 8GB video over to the tablet. Shut the tablet down and took out the card and looked at it in Gparted in Linux
The card has 2 partitions
16 MB partition FAT32
59.46 GB partition file format is unknown
The video is not on the card. It is on the tablet though. Leads me to believe that the unknown format might still have a 4GB limit.
Oh and as for my comments on Amazon. Not really dissing this at all. This is a slick tablet for the price or heck - twice the price. My commentary really was that standard Android OS supports read/write of exfat and maybe ext4?. Just wish that Amazon OS did.
Tks for your report! Let me try something out, too. Need some days to get back to you, my holidays are over.
I don't think there is answer to this. I have made 100 experiments and really only 2 things work. I can format the card FAT32 and put it into the card reader or I can format a thumb drive FAT32 and put into an adapter and into the USB C port. Any other formats in the SD card slot or via OTG on the USB C port all fail to read the file system.
In contrast - my Samsung tablet seems to accept FAT32 and exFAT formatted SD cards into the slot. It excepts FAT32 and NTFS formated thumb drives via OTG on the USB C port. Really - NTFS.
For fun I installed a terminal on the Fire HD and tried typing:
Code:
$ sudo apt-get install exfat-fuse exfat-utils
But the terminal doesn't support sudo. Probably not even close to the correct commands for the FireHD - but it adds support for exfat in Debian linux distros if not included.
Anyway - I'm still looking but for now I am transcoding some blue-rays to make smaller files. Just seems like wasted time.
I also need exfat or ntfs for SDHC cards, for few amazon fire hd 10 2019.
as I understand, Microsoft is asking for a few dollars for a exfat or ntfs licenses,
so no support in stock firmware.
write if there is news. thanks/
I found a solution to get a 128 GB micro SD card working in my Fire HD 10 11th generation. The card must be formatted as FAT32, otherwise it will not work.
I accomplished it by attaching the card to the USB-C port on the tablet (using a white USB-C adapter that came with my Pixel phone and Transcend USB card reader). The tablet detected this card and allowed me to format it. When I connected the card formatted in the tablet to PC it showed it was formatted as FAT32 and the total capacity showed correctly as 128 GB.
FAT32 maximum partition size is 2TB unfortunately Windows did not allow me to format my card as FAT32. Card needs to be formatted on Android device to be useful in Fire HD 10.
