[Samsung Galaxy Tab Plus] kemjin:
Howdy guys, :)

I was looking for the way how to mount ext4 partition micro sd card, because I want to copy bigger than 4GB size of HD mkv movie file to my Tab. I got tired to bring a bulky laptop to copy a file from my computer, connect it to TV, and bring it back to laptop desk after watching a movie. If I can do the same thing on my small and light GTP instead of a bulky laptop, it would make my life easier.

So, I tried it, then failed! :mad: As you know, microSD card format supports ONLY fat32 format, so you can't copy a file bigger than 4 GB. HD mkv movie file is usually 4.5 ~ 15GB.

What can we do? The answer is pretty simple. Format microSD card as EXT4 or NTFS and mount it on the tab! :) EXT4 or NTFS format supports bigger than 4GB file. This sounds pretty easy, but it took me 3 days to google it, and failed it.

I can't make this without your help, bydo! Thanks again! :D

The process is simple and easy.

1. Root your tab, and install "BUSYBOX" and "Drive Mount" app

2. Copy mkv files

2. Mount NTFS microSDcard and enjoy it

This process took me less than 15 min. So, even if you are a beginner, don't get scared and just follow my step. You can do that. :)

1. Root your tab. How to root? Thanks to bdigitalstudio.

If you have memory card reader or SD card slot on your laptop, you can do that way to copy root.zip file. I did it. :) As long as you have root.zip on your microSD, I guess anyway will be fine.

2. After root, go to the market (or Google Play), search SUPERUSER, and install it. After install, run it and update SU binary

3. Also search and install BUSYBOX. After install, run the app and install busybox.

Once you complete rooting, follow remain steps. Btw, I did not find or make this solution. I read Raziel_Sicily's instruction from GT 7.7 forum, and just followed it.

Thank you Raziel_Sicily!!! :)

4. Also search "Drive Mount" app and install it.

5. Format your microSD card as NTFS. (I didn't try ext4 format, but it will work as well) I used SD card slot on my laptop, and it kept showing format options only "FAT32" and "exFAT". So, I used Paragon Hard Disk Manager to format as NTFS. You don't have to use Paragon. Just try to find your way.

6. Plug in your microSD card into Tab

7. Tab will complain "This is not support format blah blah". Just ignore it. :)

8. Run "Drive Mount"

9. Uncheck "Device Filtering" at the top. You will see your microSD card as NTFS partition at the left side under "Unmounted Drives". Let's mount it. Select your microSD card, tap the mount icon on the top (2nd from right). Mount icon image looks like a External HDD with check mark.

10. When you see your microSD NTFS partition is moved to right side under "Mounted Drive", you done! :)

Your NTFS partition is located at /mnt/. You will see a new folder name.

Mine was /mnt/mmcblk1p1, and yours can be different.

Use Astro file manager, go to /mnt/your_mounted_folder, and you can use your files. :)

+ How to watch mkv movie with DTS codec?

Here is extra information. If you have the same purpose with me, you will meet some problem soon. DTS audio cannot be playable.

You use Astro, go to the mounted folder, and click the mkv movie file, it will be played with default video player or another video player app, sound won't play.

What can I make it? I use MX Video Player. Once movie is playing, you can see couple of icons on the right top corner. H/W, captions, audio, and menu from left to right.

Tap audio icon, and select "software decoding" or "blah blah blah blah (S/W)" or whatever 2nd one. Sound will be played perfect. :)

If I find more info, I will keep updating this post. :)

Thanks again, bydo, bdigitalstudio, and Raziel_Sicily
