Update: USB OTG Helper application will solve NTFS formatted USB Drives to be mounted on phone. THis is available in XDA forums only as of yet!

 

This is to notify the solution for How to fix the external SD cards mounting issues on windows 7 in Jelly bean or related Android OS.

Jelly Bean Home Screen

If you have came from ICS or GB flavors, the probability is that you have used your file exploreres within your Device to see the Exernal SD card (Micro SD here) and Internal sd card (USB Storage) in an easy ways, representing external Sd card folder and usb storage folders in their respective denomination; an easy navigation, not much confusion isn’t it?.

But ever since JB arrived, the storage devices location are little changed; perhaps accurate this time if get used to; are mounted in “/storage” path as /sdcard0 representing internal USB storage space and /sdcard1 representing microsd card
Another path /USBdisk is for the OTG (On the GO USB cable attached flash drives can be seen there in this path folder.) natively supports FAT/FAT32 formatted USB Flash drives, if NTFS support is needed, try you luck with NTFS Mounter. So, since this path has been changed, some already existing Softlinks (shortcuts in windows context) target to that sdcards.

I can put down a lot of words here, but the solution is important however; for most people, so confining with thus stated information. Since the above mentioned words help for some people who are looking for sdcard locations within their Phone; who confused seeing the external sd card folder empty :-0.
So how to fix mounting issues in windows 8, 7 or Vista is, here: just install Multi Mount SD card from Market or from your known sources and that’s it. You will see the sd cards mounted on your PC and at the same time you can access SD cards on your Phone as well. Try not use the Other methods, when using Multi Mount SD method. use Widget on your screen to activate and deactivate application aka Mounting and Unmounting Disk drives.

Hope this helps some irated patrons.
