I am having issues with the following setup on my Nexus 7. I have the eForCity Micro USB OTG to USB 2.0 Adapter and the elago Mobile Nano I USB 2.0 microSDHC Flash Memory Card Reader. I have tried two microSD cards, one 32gb and one 64gb and I am unable to copy files to the card using both Root Explorer and ES File Explorer. It says that the copy failed. I have tried formatting the as exFat, NTFS and FAT32 and no luck. Anyone out there experience this?
Thank you in advance,

You're missing a piece of the puzzle. If rooted, you should install Stickmount, which mounts external storage using the OTG Usb cable. I use it to read/write and stream media from a 32Gb microsd card using FAT32. Some custom kernels or roms natively support mounting, but I'm just stock, rooted, 4.2.1.

Thank you for your reply. Sorry, I forgot to mention that I am rooted and I was already using Stickmount. I am able to mount both the 32gb and 64gb cards and see the content on them and access the content on them but I can not copy anything to either card when connected to the Nexus 7. Any other things I can try?
It appears that I need to have the card formatted to FAT32 in order to be able to copy to the card from the Nexus 7. Does this sound correct or is there a way to get the card formatted to NTFS or exFAT?
Some custom kernels and custom roms support NTFS, but I'm just using FAT32 which works perfectly unless you need support for files over 4Gb. Easiest way to get it to work is to just format your storage with FAT32.

this is correct. android reads, but doesn't support writing to NTFS or exFAT natively. some kernels add ntfs-g, which does give you write access, but it's buggy at best.
Hello guys, I am new here...
Yesterday I rooted my devices and planned to installed Supernexus Rom. But in the forum said that it needed FAT32 micro SD so I need to format it.
Unfortunately, i dont have adapter for microSD and my USB card doesnt have slot for micro SD.
I only have USB cable that connect me to my mac.
Is there other way to format my microSD to fat32 DIRECTLY from my samsung galaxy s 3?
thanks
You need to go to Settings -> Storage and scroll to the bottom of the list. before formatting the card you most likely have to mount it.
My micro sd card on my galaxy s4

please help me
(micro sd 32gb - class 6)
I have a Samsung Galaxy Note 4 which I am no longer using as a phone, but as a media player. In it I have mounted a San Disk Ultra Plus 200GB Micro SD XC1 Card which houses my music collection. The problem is that the Micro SD Card, when mounted in the phone, is not being recognised by my Windows 10 Laptop or my iMac, running under Sierra.
Further investigations have produced the following results:
1. When the Micro SD Card is attached to either my Laptop or iMac via a card reader, both are able to read the card and its contents.
2. When I attach the phone without the Micro SD card, both my Laptop and iMac find the phone via Samsung SmartSwitch and Android File Transfer respectively.
3. When I mount the Micro SD Card into the phone neither the Laptop or Mac find the phone or the card via Samsung SmartSwitch and Android File Transfer respectively.
4. When I experimented with a 32GB micro SD Card the Laptop and iMac found both the phone and the Micro SD Card.
5. The phone as a media player plays music from the Micro SD Card with no problem
I have gone through the process of Developer Options and USB Debugging and updating the software as 2 & 4 would not work if I had not.
My conclusions from all this are:
1. I find it hard to believe the format of the card is the issue as the card reader option would not work.
2. Could the issue be the size of the card (200GB) as the smaller Micro SD Card (32GB) worked?
Any thoughts or suggestions most welcome!
When my SD card is locked, i.e. switched to read-only, it cannot be mounted via otg + sd card reader. My phone says my sd card is "corrupted".
However, if my SD card is unlocked, it can be mounted without problem.
Is it normal behavior? Recalling my memory, my old Note 2 LTE did not behave like this.
My C9 pro is running 7.1.1. I use the bundled OTG adaptor and tried both Kingston MobileLite G4 card reader and Eye-fi card reader (the reader came with my Eye-fi card years ago).
