[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] cant copy files to the phone from pc

i have, on sprint, the galaxy s3, NOT the i900 or whatever that means. mine says model number SPH-L710
i have it rooted with the phantom rom installed, with superuser permissions. however, not sure what happened
but for some reason, i can no longer transfer files, any files, from my pc to the phone. this includes pictures,
music, documents--anything. the files are my personal files and music i ripped, and never had a problem
copying before, and all this just started. unless im hooking it up wrong, which i doubt--using the usb cable from
pc port to the phone directly. it does show the charge icon, and in the usb settings, usb debugging is checked
and also checked on media device (mtp). another option which isn't checked is camera (ptp), unchecked.
what happens when i try is, on the pc i get a box that pops up and says--do you
want to copy (file name), your device might not be able to play or view the file. i do have 2 options, to skip or copy
anyway. well when i click copy, it goes through the motions, but its not on the phone. no matter what file i try, a
pic, small wav file, etc....just will not copy and no
where one the phone is the file. another issue that seems to be going on is, the best way i can
explain it is--when the phone is hooked up to the pc, is it possible for whatever it is thats running to make the
phone able to receive copied files, go to sleep? because another error message i get when trying to copy is
it sits there for awhile, then eventually says "device not responding, disconnected" and on the phone itself its
on the main home screen like i wasn't doing nothing.
ive rebooted the phone several times, same results--nothing wil copy to the phone....
sooo, what am i missing?
update--- since that post, something else now happened. the phone flashed on, saying "sd card not mounted"
when it is. it is in the right way and all that, but when i go into settings/storage...at the very bottom it says
sd card, insert sd card
lol...so what the heck is that all about? the card is definatelly in there, and astro file manager shows some
files on the card but........

Well, it could be a couple of things.
First of all, make sure you have the Samsung USB drivers installed. It could be a corrupt driver, but probably not. It won't hurt to reinstall it, anyway, just to be sure. Here's link:
http://downloadcenter.samsung.com/c...nt_L710_GSIII_Samsung_USB_Driver_v1_4_6_0.exe
Make sure your phone is not locked when you're trying to transfer files. If you have a PIN or a PATTERN lock enabled and it locks, it will disable the MTP application from trasferring files.
Try reflashing the ROM as well. Maybe the MPT application got corrupted somehow?
As a last resort, you can restore your phone to stock unrooted status and see if that resolves the issue.

I had the same thing happen to me. I fixed the problem by going into device manager and clicking on to mtp and updating it..

I had the same thing happen to my SdCard and now it is kinda dead... before yours gets damaged, remove it and insert in a PC with a sdcard reader. Run command prompt (Start>Run>cmd and enter) and do a scan disk or check disk by entering "chkdsk /x /f driverletter:" use the drive letter assigned to the sdcard then enter, let it do it's thing.
This will fix the file system and you shouldn't more problems with the sdcard not being read. As for the MTP, do as the other member said and try updating the MTP device in in device manager or uninstall the drivers and install directly from Samsung.

[Q] Xperia S - sdcard folders and files disappeared

Hello,
Today I was trying to copy some files to my Xperia S via USB from my WinXP PC. When trying to copy the files, I got the message "the device has either stopped responding or has been disconnected" with the option to skip or cancel. This happened several times, and I plugged and unplugged the cable between tries.
After giving it up, I went to the phone and found out that all my files were gone. The folders disappeared and I can't find any pictures or media files (as well as any of the files that existed before - and I have show hidden files enabled in Android File Manager app). In Settings > Storage > Internal it says that I have 25 GB free (when I should have only 2 or 3 GBs left). The current folder structure viewable in the app is probably the folders for apps that after restart, recreated the folders.
However, if I connect to PC again, I can see the old folder structure in Internal Storage and the listing of the files inside it (the photos, etc). If I try to copy inside the SDCARD or to the PC I get the same message "the device has either stopped responding or has been disconnected" and I can't open any kind of file.
I think the data is still in the SD Card, but not accessible anymore. Has anyone experienced this before and can help me?
Thanks,
andré

is your phone rooted?

I too have this problem with my Game ROMs folder with my SNES and Genesis games. I'll run the emulator and then when I go to find a game the folder has disappeared. I have them saved on my PC so I just copy it over but an actual solution would be nice. My phone is rooted and ROMed.
Oh and I tried Titanium Backups but they sometimes disappear as well. I've never had that app work for me anyways always freezes and the backup is never restored.
It seems to me large folders and files not involved in the phones dedicated folder structure seem to disappear.

The best thing for you to do would be to root your phone and try the SD card mounting app which mounts the SD card in mass storage mode. MTP mode always gives such problem so and is unreliable..

Exactly. MTP has lots of problem.
I don't understand why Android use it.

Sdcard content gone?! Help!

Hi,
This is totally weird! And it happened with my iPhone as well some time ago.
I connected my phone to PC
Galaxy nexus appeared in My Computer (Windows 8)
I did some file operations (deleted some files in Nexus, copied some photos)
And then PC said that Windows can't access files in Nexus
I disconnected and phone file manager see only an empty sd card
Settings show 8GB or more of free space
After reboot of the phone - no changes. Still not a single file left on my sdcard
I lost my photos but all of the are synced with G+. No problem with that I hope. And I'm now making a nandoid and will make a tibackup after that to save my settings, app/game progress and SMS/MMS.
But why this is happening?
Any ways to recover?

[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.
