[Q] OUYA doesn't recognize external storage formated to ext4/3/2

I'm not exactly new to linux, or android, but I'm not familiar with how android treats external storage vs. internal.
I had advised a few people to format their external drives as ext4 since the kernel would probably support it (and the system, data and cache partitions are ext4 so it DOES). However, when I format my external storage (32gb and 1gb USB sticks) to ext*, it doesn't show up, even in the logcat or in ES File Explorer (or a mount command, but with no root or fdisk -l i didn't dig too far).
So I was wondering if anyone happens to know why thats the case. Clearly the kernel supprots ext4, but you can't mount external storage with it?
FYI, so far that I've seen, I can't format external storage with the ouya. It also only supports NTFS read, and FAT32 R/W.

I've asked this question too, I tried with different harddrives to all the ext formats and nothing picks it up. there are a few apps like ntfs mounter which supports ext but requires rooting.

Android only recognises FAT32 and I think CDFS and UDF. May also recognise FAT16. NTFS and exFAT are both patented so need expensive licenses for a manufacturer to include them in devices (a few do on their modified firmwares).
I have no idea why ext isn't supported though. I presume it is something to do with the relative rarity of ext drives outside of Linux boot devices.

isnt the internal memory ext4?

anyone who has there ouya rooted could you please try one of the harddrive mounting apks like paragon or ntfs mounter and see if the ext formats get picked up?

got ext3 working with usb otg helper app. You need root access.

No problem mounting ext4
Just made myself a 15GB ext4 formatted second partition on a 32GB usb drive. Just because Ouya only looks at the first partition, and assumes it's fat32 should not discourage you. Just open a adb shell to your Ouya, become superuser, create a directory /mnt/mydata, and mount it:
In adb shell:
1. su
2. mkdir /mnt/mydata
3. mount -t ext4 /dev/block/vold/8\:2 /mnt/mydata

There is in fact a standard read-only NTFS driver in LInux, and it's supported on the OUYA. An NTFS-formatted USB hard drive automounts upon hot plugin.

I finally got a reply back from ouya support about ext3/4 not being recognized and they said its been resolved. Looking forward to the next firmware.

Ntfs/exfat help

I switched from my Asus TF300t to this tablet and processing/graphics are great but business/productivity is lacking. Is there a way to get NTFS working on the device? I have a 2TB hdd that worked great on 4.3 with the Asus but no such luck on the Note.
If I have to root that is fine, but I cant find a thread with instructions. I knlw about paragon but that didnt work on my Note 3.
Thanks

Back up your data and format your hard drive to ext, then copy back

Hi
You have two options:
1) You can find a kernel with SELinux permissive, install it (you will have knox counter switched to 1 and goodbye warranty...), and after you can install "Paragon exFAT, NTFS & HFS+" that works great.
2) Install Total Commander and his USB plugin, in this way you will have read-only access no ntfs usb drives.

Joe

Sweet, thanks. Looks like I'm going to root.

Any idea on where to find such permissive kernel for sm-p605? And possibly how to install?

[Q] Cannot mount USB flash drive on rooted Fire TV

I just got a FireTV, it's rooted, on the latest pre-rooted 51.1.4.1_514013920
I've tried to mount a few USB flash drives (16-64GB, NTFS or FAT32 formatted) via a USB hub and directly plugged into the USB port on the AFTV. I can't get it to work. I'm using the latest version of StickMount installed from the Google Play Store and also tried adbFire the USB mount option.
StickMount doesn't do anything and if I try to click Mount or Unmount again it says the service is busy.
adbFire shows a /usb/drive1 via SMB but it's empty, it's not the actual flash drive.
How do I troubleshoot this? I must be missing something simple.

hi you could try Busymount: http://forum.xda-developers.com/fire-tv/development/busymount-v1-0-t2920146
which mounts the drives on boot, much better than stickmount and can be customized to your needs.
Uninstall Stickmount first though as i think they conflict.

Thanks, I'll give that a try. I should also try to see first if I can see the USB flash drive from CWM, it will at least tell me everything is fine from a hardware perspective.
I installed BusyBox via adbFire, is there some other version of BusyBox required? BusyMount says it comes with BusyBox but I'm not sure whether that means it replaces any existing BusyBox or it installs its own version for its own use.

Also, what is the recommended format for external flash drives for best performance, to be writable and to be able to use from CWM to flash new ROMs, etc.? ext4, FAT32? Does it matter?

im not sure what formats work best but it depends on the type of files. Ive always used NTFS for big drives and FAT32 for flash usb.
and i installed it via adbfire also, think that is all u need.

Note II GT-N7100 READ NTFS USB OTG

Dear friends I searched a lot but could not get a clear answer to this topic. For some it works for others its NO. Along with a lot of other confusions.
But I got it working. How, here it is.
You need (what I had)
Rooted Note 2 (7100)
SELinux Mode Changer
Paragon exFAT, NTFS & HFS+
After installing these, reboot device and SElinux changes to permissive automatically. Just verify manually. Insert a NTFS partitioned USB drive to device with OTG cable. Open paragon you installed earlier. Press mount (automatically). Mounted drive ? Yes, then OK. Otherwise press manually. It will show a mount path. Just check whether the destination folder exists otherwise create it. Try mounting again manually. All done. In my case mount was at mnt/usb1, where I had to create usb1 manually.
Enjoy you NTFS drives on N2. Thanx.
I flashed DN4 V2.1

Any way to get NTFS USB OTG working in 9.0 Pie?

Wondering if anyone has managed to figure out a way to get this working, or if I'm just missing something. I've tried everything I can find online, including a custom kernel (EX), (both) paragon NTFS mounting utilities, stickmount, a couple different TWRP-flashable .zip's, as well as miscellaneous other root apps that supposedly will mount NTFS, all to no avail.
Running 9.0, stock rooted + EX kernel and Magisk. And unfortunately FAT32 or other formatting isn't an option in my case. Any thoughts or advice or is this just a no go? Thanks!

Android doesn't support NTFS and is unlikely to ever support it. If none of the apps you've tried work then there isn't anything you can do except format the drive you want to use as FAT32. I know that isn't an option, but you don't havr many options here.

Paragon "works", but only in a couple of specialized file managers. There's no generic solution I've seen that simply mounts OTG as a directory. There is a Magisk package that claims to do this with vold, but it's only supported by an older Magisk version and doesn't support Android 9 yet.

Android only supports FAT32/Ext3/Ext4/exFAT. Why is FAT32 not an option? It will support up to 2TB partitions and although it doesn't natively support encryption, it is possible to encrypt data on a FAT32 formatted partition. What is it you are trying to accomplish?

The OP likely has a device formatted as NTFS and doesn't want to go through the trouble of pulling off the data, formatting, and replacing the data. Unfortunately for him, he's going to have little choice but to fornat to be able to use it.

exFAT USB drive wasn't supported on my P2XL Pie, tested a few days ago. Had to format FAT32 through Android (since the only options were FAT32 and NTFS in Windows File Explorer).

i may be a little late to this thread, but
total commander from c. ghisler and
usb stick plugin (tc) from ferenc hechler
does that. it worked on Android 8 at least, on android 9 i have some troubles atm, i can only copy data to my expandable sd card storage, but maybe it's a bug on my hand, worth a shot.
there is a free version of the usb stick plugin as well and total commander was always free without ads
