Some of you might already know that I accidentally formatted my 64gb SDCard to ext4. I tried to format it again back to exFAT but I can't. Windows isn't detecting it. Tried different applications like MiniTool Partition and still no go. Tried to use Ubuntu on a virtual machine and still nothing. My last hope is to use a kernel supporting ext4. So how do I implement ext4 support?

I have made (approximately) 512MB ext2 partition and used INSTALL.EXE. But haret gives me "no filesystem could mount root" and reboot.
Any ideas? Tested gingerbread and CM6.1. Both gives same results.
Possibly bad SD card?
You also prepared a linux swap partition of 64 MB?
And did you make your fat32, ext2 and linux swap primary?
If those are the case, then it should work afaik.
Else you might want to try a different SD card yes.
Nope, i just had primary fat32 and logical ext2.
I have recreated the way, you said and it works. Thanks!
Glad to see I helped, have fun with android!

You must set fat32 primary in first partition, and set ext2 primary in second partition, Important! ext2 primary must less than 512MB！Just format Fat32, don't format ext2.
Does anyone know if you can format the storage partition on the sdcard as ntfs or ext4.
Reason for this is if you want to put hd movies on your sd card and they are over 4GB you can't do this with FAT32.
So you would need to format it in a different partition. Anyone know if it works ?

You format it to ExFat. That is the new sdcard format to get it to store more than 4gb. How you are going to do it I don't know. If it were stock, formatting that is easy, but CM10, I don't know. NTSF won't work but ext4 should. You can use partitioning software to do that.
Sent from my Nook HD running CM10.1 on SD
I know that stock sense kernel comes with exfat, however if you're using a custom kernel like I do exfat might probably not work.
What about ext3/4? I tried formatting my external sdcard ext4 but it won't be properly recognized by android.
Is there a way to achieve this in our devices?
I'd like to remove my external SD card and use my Linux (RHEL/CentOS) workstation to copy files to and from it. The card has not been encrypted and is 6¤ GB in size.
Unfortunately the workstation did not recognize the file format, Solid Explorer on the tablet does not tell me which file system is used and Googling suggests it may be a special flash file system suitable for SD cards, presumably not available on desktop Linux distributions.
Does anyone have information?
Probably exfat.
Diskinfo will tell you what it is.
Should be FAT or exFAT
Thank you, have downloaded DiskInfo from the Play Store to my phones but not yet to the tablet. I know RHEL/CentOS has drivers for MSDOS (FAT) and vFAT but do not know about exFAT.

It is definitely exfat and it is an exfat flavor that can't be duplicated on Windows according to Microsloth. Although you should be able to read/write the card from a Windows PC do not try to format it on a PC. The M/S exfat format does not handle large filesystem cards.
You can read/write and I think format the card (if needed) from Linux using exfat-fuse. I built it from source the other day, took all of three minutes. Good stuff!
Depending on your package manager you should be able to search on exfat or fuse and find the drivers.
BTW I did some experimenting with card filesystems since the internal memory is supposedly ext4. I formatted a memory card ext3 and the S7 couldn't read it.
Would have been nice to have a standard portable filesystem available instead of having to use something proprietary that google has to pay Microslop for.

Have had no issues formatting 64gb sd cards as exFAT in Windows. I see no reason why it wouldn't be compatible.
It's a Windows format that has been incorporated to work on Samsung Android devices.
As for Google I don't think exfat is yet natively supported on AOSP unless it's been added recently.
You were right, a small SD card used VFAT while a 64 GB card used exFAT. The former can be read natively on RHEL/CentOS and there are third-party drivers for the latter.
Thank you, DiskInfo looks like a very nice utility.
Hi,
I know that for a USB-OTG stick can use Paragon to make exFAT and NTFS work.
How about microSD and exFAT for LOS 18.1 (/e/OS) on S10?
It doesn't work for me and If that doesn't work in general, then I would mind using NTFS or ext4 format.
I've also tried both and it doesn't work when I format it with Linux.
When I format it with Android built in formating option, then it does it with FAT32. I've tried to copy a 8GB File onto the SD and it give's me the impression that it was successful (no error message) when it actually wasn't. This is just a fun fact
My linux refused to copy a 8GB File to SD via MTP. This is how it should be with FAT32.
Thanks for sharing your experience.
