[Q] I Can't access MicroSD through the PC

Hi. I'm new to the forums and android. Sorry if this is not the correct place to post this.
When I connect my phone to the PC via USB I only see a few folders and none of the media files in the phone. I've tried accessing through Media Link and Windows Explorer and nothing.
Weird thing is that I see some folders and photos, like the photos taken with the RetroCamera Application.
I have been able to access my files before, it just suddenly stopped working.
Any ideas?

Try using different USB [if already did]
Go to your Hardware devices, change the MTP devices drivers to USB drivers manually [update them choose them manually from list]
Hopefully you'll get it working again

First,you should make sure that your MicroSD's file system is OK.

Can you access the files with your phone's file browser?if you can do that,the sd card might be OK,then you can check the OS.But if you can't,you may have to format the sd card.

this is normal if USB mode is set to windows media sync, its some kind of security feature I think.
you have 2 options:
1. attempt to access via the moto web phone portal as above, you need to set the USB mode to 'motorola phone portal'. but this I find is a bit hit and miss, you can manually connect using this address:
http://192.168.16.2:8080/webfolder
this can be entered into start -> run, in windows explorer, or mapped directly as a network drive
2. go into USB options and change the mode to 'USB mass storage' this will mount the SD card as a proper removable drive and show all the files properly. This option may not be available depending on what firmware is loaded onto the phone though!
to change USB mode swipe the status/menu bar at the top of the phone down, and tap 'USB connection'

I've used the moto web portal and I was able to access my files, however, it draggs when moving files. Also, the phone was in USB Mass Storage mode the whole time.
Today I connected my phone to my laptop at the office and even though the Motorola Media Link did not pick up my media files, I was able to access them through Windows Explorer. So I'm leaning towards a driver issue with my home PC.

ah ok, maybe the drivers haven't fully installed, check in the device manager to see of you can spot anything. you could also try changing the usb mode to a different setting then back again, see if that kicks the pc into installing the correct drivers

I re-installed the drivers, but still no go.
What surprises me the most is that I can't access or even see some of the folders in my SD Card. The Motorola Media Link recognizes that there is something in the card, but can't tell what it is.
Googling for days, I found this, but I don't know how to do it or even it is related to my problem:
"Finally i solve the problem. And everything in my ext sd card is back. Problem is emmc folder (means external sd card in cyanogenmod 7) not permitted for write and read.
I use QtADB Terminal for editing the directorys permition.
Step 1: type "su"
Step 2: go to root directory. If you type "ls" and can you see "emmc" you are right position.
Step 3: "chmod 777 emmc" or "$chmod 777 emmc" (for write and read permitted.)
Step 4: Reboot the phone and everythings are back in External Sd Card in EMMC
And Windows detect 2 Storage Drive now. One of 6GB Internal Sd Card, One of 8GB External Sd Card. And i can use my Music player Power AMP.
Everythings perfect for me now. Cyanogen is great ROM but this permision problem should bu fixed. Because i spend three day for solve this problem."

[Q] USB Mass storage replacement?

Hi
I have my gnex since 4 month and I still search for a solution to replace the usb mass storage option that I had with my motorola defy(RIP).
So I was used to use USB mass storage for:
1- Store Keepass DB on SDcard and access it with Keepass Droid or Keepass portable (on my laptop) which point to my sdcard.
2- open and modify document on my SDcard
I know that there's dropbox or other online service but they are prohibited at work.
The other option I think of is that all the file from my phone automatically sync to my laptop when I plug the usb cable but I don't know how to do that!
Any suggestion?
Thanks
Daniel

You will never be able to setup the Galaxy Nexus to use USB Mass Storage.
MTP still lets you access files on your phone's virtual "SDcard" (just the /sdcard/ directory).

I know but i'm looking for other way to achieve this!
Having the phone syncing file automaticaly on the laptop when connected would solve my problem!
I want my file sync with the laptop file like folder sync do but with the usb cable to the laptop.
Thanks

Really don't think there's a way to do this. You're stuck with MTP on this phone.

I use a WebDAV server app to mount my GN's storage on my computers. The app I use is called "WebDAV server" and can be found on Google Play. Once you start this app on your phone, you can use a WebDAV client program on your computer to mount the phone storage as a Windows drive or Mac shared folder. I use Windows and the free-for-personal use program called NetDrive as the WebDAV client. I don't believe I've found any difference between doing this and having the storage available as a USB mass storage device.

[Q] wifi sd card folder on pc

hi! its there a way to make an folder on the pc of your sd card or internal memory (in the one x case)..i mean, you know the app wifi file explorer you have to enter an ip on you browser to access your phones memory over wifi right, well what im asking is, that if it is possible to make a folder of your phone memory, and leave it on your computer, and everytime youre at your home and connect to the wifi, the folder is active and you can access that folder any time, without using any other app
if theres no way to make that, it will be a really good idea dont you think?

You would have to install an app on your phone. In order to not install anything, the feature should have been included in the Android OS, and I don't think that will happen any time soon.

[APP] - Android File Transfer, issues on Note 3

***SOLUTION FOUND! I CAN NOW ACCESS THE FOLDER. SEE POST BELOW.***
Android File Transfer was working great up until a few days ago when it started to bug out, only for when trying to access the Camera folder on my exSD Card.
I can access everything else except when clicking on this folder the message pops up, which makes no sense because my screen isn't locked. (Screenshot attached.)
Could it be that the amount of pictures/videos on the exSD card is too much to handle for AFT? After all, it is a 64GB card...which is a lot of land to cover and load....hmmmm
I've tried this, but no luck.
Note: I'm aware of AirDroid etc...Personally I prefer to be plugged in direct via USB.

Not really a theme Or app question but I'll give it a swing.
Can you access it on your phone fine?
Did you try using a card reader an see if you can access it that way?
If it's stating locked, it may have set permissions on your folder that inhibit access? Check those in a root explorer an see what they say too

Mod, can you move this over to the proper forum. Thanks.
Possible causes / Things I've tried:
I do have some pictures in an App called: KeepSafe, where you have to enter in a pin code to access those pics, so then I was thinking maybe this was causing the problem. So I entered the App and tried connecting, but darn...same old thing. Doesn't work and I keep getting the same error message as the pic I have attached to the original thread.
I have also tried to reboot in Recovery (twrp) and tried to mount the exSD, but still nothing. Here's the message it gave me:
E: Unable to mount '/usbstorage'
This is driving me crazy. Anyone?

Can you access it on your phone fine? - Yes I can access it just fine through ES File Explorer. I've also checked the permissions.
Did you try using a card reader an see if you can access it that way? - I'm sure it'll work fine with a card reader, but that's not my preferred method. It's just frustrating for something to have worked and out of the blue stop.
If it's stating locked, it may have set permissions on your folder that inhibit access? Check those in a root explorer an see what they say too - I've uploaded a screen shot of the message that I'm receiving.

Try moving the KeepSafe files to another directory.

Update 6/30/14
SUCCESS!
From the gallery on your phone, you can create folders and move (not copy) over pictures/videos and it'll be default save it to your phones internal SD card.
I didn't want to move all 4,000+ pics/vids so I just did it in little batches of 20 here 50 there and made just a few folders.
Then I connected the phone to my computer and accessed the Camera folder and....bam there it OPENS!
My theory:
If you have more than ~50% of your external SD card filled up then chances are your computer (Android File Transfer, for Mac users) will have a hard time trying to access that huge folder that is < 30+GB's ...
Therefore, you just have to lighten up the load on that folder so that it can be accessed with ease...
Pretty straight forward and simple.

It is more likely that they thought it very unlikely that there would be more than the old limit of 2,000 files in a directory so they didn't allow for it in the program code.

Your usb stick is not a computer, it does not need to read your phone with MTP protocol.
The phone should provide power to the USB stick, exactly as it is saying, so that your phone can read the contents of the USB stick.
Get a File Manager like FX to transfer items to and from your USB stick.

I have the same problem. It always says usb charging and I could not transfer pictures to my usb using the usb-c/usb adaptor. I tried using file manager app but I get confused with all these asking permissions and I end up unable to transfer anything. I never had this problem with my S7 edge before. I tried connecting the phone directly to the mac using android file transfer but could not connect. I would really appreciate if someone can give us a more detailed steps on how.

I tried that I have ES file explorer like "edsol" said it won't mount the stick because it's in charging mode
I tried several time to switch it off of charging mode but always flips back after a few seconds.
if "edsol" has the same problem then I guess it's not just my phone........there must be a fix for this??

I had the same situation, and I had to format the USB stick in "exFAT" to be able to copy files to it. NTFS is supported only for reading, but not for writing.
So check that your USB stick is not NTFS.
FAT32 and exFAT are the same, the difference is that exFAT doesn't have the FAT32 limitations (maximum file size of 4 GB)

Thanks...but it is exFat......I did a reformat just incase.......still a no go ??

you probably need some file manager to do what you want, Android sucks when it comes to manual file management.
Anyway I have ES file explorer loaded on my phone, so plugged in USB c to USB2 adapter, put in 32 GB FAT32 memory stick, ES file exp. open up and I transferred couple files from stick to SD, just to test it if it works. It did, but you would have to pay me a lot of money to do it on regular basis, so awkward. I just plug my phone to PC and use windows click and drag to move files around. Now I run into problem, when I was transferring my pictures, couple days ago, F???? Android lock my sd card for no reason (F????? Google is messing SD cards on phones since at least kitkat). I had to fix sd and take write protect off, but I'm sure it's Google not Samsung. Anyway, it works like a charm, just watch out for Google's broken permissions showing it's ugly head.

What File Explorer are you using? Some of them can't write to external storage because of Marshmallow permissions.
"My Files" of Samsung worked for me while "ES File Explorer" didn't work (before root)

I used ES File Explorer, I'm sorry I said wrong in my previous post, I moved couple files to phones DCIM folder, not SD, it's so awkward and I just wanted to see if it works at all, it did, I confirmed the files were moved, before deleting them. So actually I don't know if it would work on SD card, but I would never ever transfer files like that: I would use my pc laptop for direct transfer between SD and stick. So the concept I described works, but as far as permissions to particular folders go, they're so messed up and don't even want to test it again against SD. In theory it should work at least for transfer to root directory, since card is not protected, may not work for transfer to folders created by other programs due to permissions. At some point I may have to root this phone just to fix those stupid permissions, but I haven't used Marshmallow until now, so not sure how broken those permissions are here.

so can't even attempt to transfer anything....this is frustrating !!
