SD Card file system - Galaxy Tab S Q&A, Help & Troubleshooting

I've upgraded the mSD card in my tablet from 32Gb to 128Gb.
The tablet offered to format the card either as a removable storage or as an internal storage that will not be usable outside of the tables.
Anyone knows what file system type is used for that?
And is it something Samsung or Google came up with.

Internal Storage

This is my first Android Phone without an SD card slot (Had Samsung Galaxy, Thunderbolt and Bionic before). Trying to understand. Is the Internal Storage a physical storage medium like you find in the iPhone or is it an internal SD card? Some people talk about virtual SD drive and partitioning. Am I able to partition the internal storage so that part of it will work like an external SD card and does not get erased with ROM upgrades? Thanks

the internal memory is a nand chip, it's much better than having a microsd card like the HD7 and mozart, as it runs much faster, and less error.
but not too sure about partitioning it, as you only get about just over 13GB users memory.

[Q] n7102 Low Phone Storage Space

Hi everyone, I'm new to these forums so please go easy. I'm not even sure if this is the right place to post about the n7102 because there's no section for this phone.
Basically, my problem is that I've recently run out of space on n7102. I cannot download more apps from the Google Play Store. I have tried using Lucky Patcher to remove bug fixes and also tried deleting dalvik-cache, but I think that fixes an entirely different problem.
My device has the following storage spaces:
Phone storage: 500mb
Internal storage: 2gb
External SD card: 16gb
For some reason, the phone writes to the external sd card where I store my media files. However, the internal storage is not even used at the moment. Right now, some apps are saved to the external sd card so my widgets take a while to load on startup. I think this might be because I wiped reformatted my internal memory card after i reformatted my external sd card through Settings > Apps.
I want to know if it is possible to:
1. repartition the phone storage (500mb) to include the unused 2 gb internal storage (total 2.5gb); or
2. swap these two partitions (phone storage 2 gb, internal storage 2.5gb)
I do not want to make a partition on my external sd card to extend my phone storage to use as data
I've looked on the web and this is what I have found:
- MT6577 2GB data repartition with int2ext: http://forum.xda-developers.com/showthread.php?t=1914184
- Swapping internal and external sd card: http://forum.xda-developers.com/showthread.php?t=1716166
- Mounting /data partition onto the internal storage space: http://forum.xda-developers.com/showthread.php?t=1648411
I've looked at a lot more pages concerning issues similar to this, but a lot of the time they use phone storage/internal storage/external sd storage, etc., interchangably. It can get quite confusing. I understand that android sees its internal storage and external storage space the same.
I've also read about the file "Mt657xRepartition_EN.rar" and wonder if it can be used on the n7102 without any problems.
Anyhow, thanks for reading this. If you can help, please do. I appreciate it. I only recently got this phone and have been tinkering with it the past few days. Before, I had been using an Xperia U that had 2 GB of phone storage vs the n7102's 500mb of phone storage so I have not run into this problem before.
Cheers.
[UPDATE] I am not sure but the two internal storage spaces may not be merged. I might have to try to use link2sd between these two for apps and save the external sd card for personal storage use.

does anyone know how to swap mount points for SD card and internal storage

I remember there being a mod for the note 2 that would essentially replace the internal memory with whatever SD card you had....that way apps that only ran on "internal" memory could be installed on devices with limited memory via SD card...they did it by swapping the mount points, essentially making a 128gb tab s...any idea if that could be done here?
Yes you can

It is possible but not as that easy way; you have to erase the target sd card and also have to start from zero your tab S; also need to root your tablet and format the sd card as the same format that you have on your sd card. There is a procedure but I don't remember where.

Micro SD card reading issue

Hi I was hoping someone would know how to do this.
I have a slight issue on my HTC One M8 the charging port isn't working anymore and I will get the port replaced.
However in the meantime the micro SD was used as internal storage I have a lot of media on there I wish to keep and when inserting the SD card into a pc or another phone it's unable to read the SD card. Probably replacing the port once its fixed will solve the problem but in the meantime does anyone know of anyway how to view the contents of the SD card from inserting the memory card into a pc?
Help with this would be much appreciated thanks.

You can't do this (mount on PC) once you've selected to use the SD as internal storage. That is the whole point of using it as internal storage, the SD is an "extension" of the phone's internal storage. Only part of the files are on the SD, and some are on the phone's built-in storage. And the way computers write files, there is nothing saying that the fragments of a file are in any one location (part of a file may be on SD, part may be on the phone's built-in storage).
Stated more simply, the SD is now just part of a whole. By taking it out, you now just have a part of the whole; therefore breaking it, so it can't be read on a PC.
That's why there are two options given in Marshmallow when you insert an SD, to format as internal or removable storage. You can't have both. By picking internal storage, by definition, its not removable (can't be read by another device once its removed).

Thanks for clarifying I have the port in for repair and the technician said he won't be hard resetting the phone so hopefully I'll be able to still get into the SD card after.

Negative SD Card Storage Size?

I installed crdroid Android 7.1 to my d855 LG g3 today. Everything was fine until I checked my SD card storage. It gives me two options to use my SD card. First one is external storage which does not allow me to move apps to it, second option is internal. When I choose internal, it shows me a negative storage (-45gb). And apps can't be moved there because phone thinks there is not enough storage in the SD card. My SD card is Samsung evo with 64gb storage. Can anyone help me?
