Star s5/Miz Z2 - unable to mount phone storage memory - Android Q&A, Help & Troubleshooting

Just formatted via USB my phone storage (5gb total) splitting it in 4gb (data) 1gb (ext2 for apps). I put back the original files and folders previously backeupped in the data partition but now the phone doesn't want to mount the memory.
Naturally I can access the memory via USB every time I connect the phone to the PC.
Any idea?

[Q] internal sd not visible using USB Mass storage option

I am unable to access/see the internal SD when I plug in to USB and choose USB Mass Storage option. I can access the external SD, but internal now refuses to mount. I rooted for the first time about a month ago and have not had the time to do anything further beyond a Titanium backup. Everything is present and working properly, I can use a file explorer to see the internal memory, but cannot access or manipulate via PC. My Computer presents two drives (internal and Ext SD), but clicking on the one that should be internal gets me the popup "please insert disc into drive..." This did not happen at the same time as root, have been rooted several weeks before problem appeared.

Corrupted internal memory

So a while ago I noticed that when I do a factory reset on my phone, the apps that I HAVE INSTALLED remain installed. Even if I delete them I don't have access to the rest of the memory, I have about 2,4GB free of 4GB. (Note: The phone has and 8GB internal storage, and before I encountered this problem I had access to the 4GB)
Now for the other part. When I connect my phone to my PC, it should show 2 drives well mine doesn't show the second one anymore (which is the internal storage) just the SD one. If I remove the SD and plug my phone back into my PC, it shows the Partition of the internal memory, called G:, but I get this error message, G:/ Is not accessible. Incorrect function. .
I've tried to format it but it doesn't work. Any other ideas would be appreciated.

Emulate/Mount hidden internal storage[2GB]

Currently my device only shows one sdcard in all file managers , [/sdcard][ The one which is inserted in sdcard slot externally ] [16GB].
This device consist of total 4GB internal storage , wherin the 2GB are reserved for apps , and other 2GB is just left over [NO-use , seriously !]
When i connect my phone to computer when TWRP is running , it also mounts the internal storage[2GB][LEFT-OVER PART] & external storage[16GB][/sdcard]
But when phone is normally turned on the file managers display's the external storage[16GB][/sdcard] only,
-In addition, mass storage mode only shows the external sdcard [16GB].

Unable to transfer files properly between redmi note 4 and PC.

Hi I am Rupesh from India and I have a PC and redmi note 4 with 64 GB internal storage. I want to transfer files between redmi note 4 and PC but can't. I am getting a number of errors while transferring in various situations.
I have a folder in external SD card which contains 500 mp3 files of size 2.5 GB. I have tried to move these files to a folder in PC and unfortunately 150 files are transferred properly with correct size and remaining 350 files are copied with zero size for all files. Finally I have lost 350 files in SD card so I have tried to recover using data recovery software in redmi note 4 itself but failed. In order to transfer these files I have compressed them after that copied the resulted zip file to PC and succeeded.
I have three text files in a folder of PC. First I have selected these three text files and selected copy option after that I have connected the phone to PC and selected transfer files option after that in internal storage I have made right click and I can't find paste option and even I have pressed Ctrl+v and no use. I have tried to copy these text files to lenovo a3000 internal storage which is connected as USB storage and successfully completed.
Previously I have tried to copy 2000 mp3 files of size 9 GB and unfortunately 1500 files are copied and remaining left un copied.
Suppose if I want to copy a folder containing 1000 files from PC to redmi note 4 and the phone already contains 500 files. I want to copy remaining 500 files and skip already existing files. I have tried copy and paste and it asked confirmation to replace existing files or not and I have selected no and after that the paste process is taking lot of time. If I try to copy these 1000 files to an empty folder of phone storage the paste process is taking less time than above.
I have used a number of android phones and tabs and all of them have an option to mount storage as USB storage in PC but redmi note 4 doesn't. Can anyone of you suggest how to mount internal storage or external SD card as USB storage. Is there any android app which allows mounting as USB storage.
My PC runs Windows 8.1 pro and my phone runs MIUI 9.
Is there any PC companion suite specifically for redmi note 4 which allows transferring files between redmi note 4 and PC with minimum errors.
Regards,
Rupesh.
Is it possible to transfer huge amount of files between PC and redmi note 4 using the software specified above.
At present I have rooted my phone and installed custom recovery and so is there any firmware or app in order to mount internal and external storages as USB removable storage drives.

USB storage? Like the normal "transfer files" option, or MTP storage (USB debugging option)? You can use TWRP and I think that mounts both drives as USB storage.
Did you convert your SD card to internal storage? Or is it portable storage? When you take the SD card out and insert it into your computer, do you have access to your files, or no? If not, it's configured as internal storage.

USB storage I mean I want to use it as normal USB removable storage like pen drive. Up to now I have connected my phone to computer by turning on USB debugging option.
In mtp mode file transfer is taking lot of time that too error prone. Suppose I want to copy a directory containing 100 sub directories and 2000 mp3 files from PC to my internal storage and when I try to paste and it will ask do you want to skip already existing file's and when I select yes it is taking up to 1.5 hours just to skip already existing file's.
In mtp mode when I connect my phone to PC in Windows explorer I am able to see an entry called android phone and when I enter into it I am able to see two entries called "internal storage" and external SD card. I have another android device ie., tablet called lenovo a3000 h and when I connect it to my PC I am able to see two entries with new drives for internal storage and external storages like g: drive for internal storage and h: drive for external storage. When I try to copy files from PC to my tab the file transfer is very fast without any errors and also skipping existing file's is also fast. The tab is running ice cream Sandwich and my phone is running nought.
My external SD card is portable I mean I am able to access the files present in it when I connect it to PC using card reader. The problem is my phone ie., redmi note 4 is a sealed piece I mean if I want to take SD card out I have to use a needle.
I think that you have understood my problem and so can you try to suggest how to connect my internal and external storages as g: and h: drives.

If you want to use it as normal removable storage, that's called portable mode. When you first inserted your SD card into your device, it might have given you two options: format as portable storage or internal storage. Those are the options I was presented with on LOS 15.1. I don't know how it works on MIUI.
If portable storage, then your SD card should show up as another entry when you connect your phone to your computer. If internal storage, only one entry shows (since your SD card is combined with your internal storage). Since I formatted my SD card as internal storage, it shows up as one entry when I connect and select the "Transfer files" option.
In TWRP, the SD card and internal storage show up as two distinct entries (I guess that's just how TWRP works).
It sounds like there's something wrong with your SD card, IMO. Remove it to the phone and insert it into the computer by itself. Format it, then put it back into your phone and see if that fixes anything.
