[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."

Update for 4.0.4 power saving and USB problems

I've had this Sprint Galaxy S II phone for about two or three weeks, and it just updated to 4.0.4. The only problems I am having are these:
1. power saving is set to come on at 50%, but it doesn't. Lately, I have been home and have been able to charge it or happened to look at it when it was just below 50%. If I go into the settings and manually uncheck and check it again, it turns on power saving. Any way to fix this?
2. I've never messed with the SD card yet. The card is the same as my old phone's, so there's stuff on it I can't delete. Anyway, I think they changed the way this connected to PCs because the old image of Andru on the screen is gone. So, now when I connect it, my computer thinks it's a camera. If the icons are in tile view, it won't show you the folder or file names. And it won't let me paste music (only thing I'm trying to do) onto the SD card. Now, FYI, my fiance just reinstalled my OS (XP) because of some computer problems I was having, so maybe there's some XP update I need for this to connect to the PC. If I can connect the card to the computer without the phone, I'll try that, but I don't know how.

I'm not sure about the power saving mode, but I ran into the issue with the sd card. I fixed it by installing the Samsung drivers (which can be found by a quick Google search, or by searching these forums) and turned on mass storage mode. I'm running xp as well and it shows up under removable storage F: & G: in the my computer folder. Hope this helps

How do you turn on mass storage mode? The Sprint guy had me download the drivers, but the device wasn't recognized by the PC when I did. I then got SP 3 for Windows, but I haven't noticed any difference, so I am not sure if there's something else my computer is missing.

When you connect the phone a us icon shows in the status bar, swipe down and touch the notification then it will allow you to turn it on.

I called Sprint today because I was still having this issue with the SD card, and they told me that since I was using Windows XP, I would never be able to see the SD card because it was too old an OS. I can't find anything online I should download, so I thought I'd check here again to see if there was a way around this. I figured if anyone would know, it would be the people on this forum.
P.S. I am still having the power saving mode issue but forgot to ask them about that.

lolwat? XP may be old, but not old enough to still support USB mass.
ICS uses a new USB setup for connecting using MTP, and another older mode I don't remember the letters for offhand. XP should read MTP but not the other, but you typically need Samsung drivers for either. Market has an app, https://play.google.com/store/apps/details?id=in.zatta.USB_switch USB Switcher that will change the USB mode from MTP to mass, after rebooting your phone. Works on my E4GT, so presumably it might for yours. Hope that helps.
Edit: It is possible though for certain size cards to not be read by XP depending on certain settings or hardware, I dunno if that's what they meant by that, I assumed you meant connecting to the card via USB on the phone. If I got that wrong my apologies, hope this helps regardless.

I'm not sure how big my SD card is as the fiance gave it to me, and I don't recall. He is the computer expert around here, so I don't pay much attention to what he does to the computers, etc. Yes, dear, whatever you say dear. Dual core, 80 Gig, micro SD card reader...if he wants me to use it, I trust that it's good. He actually told me that he bought extra licenses for Win 7, so we could install it on my computer, but I am not a fan of how Win 7 programs are organized differently from their older versions. (I may be thinking of 2010 Office Suite and just lumping that in with 7). So, I told him maybe in two years I'd upgrade to 7. For now I'll just transfer the files between two computers with a flash drive.
I KNEW this was an ICS thing. Even though I had the phone for less than a month before the update and didn't remember plugging it into the computer before then. My phone does prompt file transfer for MTP and whatever acronym they use for pictures. And I'm like, fine, I'll deal with that, but when I try to use the programs suggested to transfer files, the programs freeze or don't recognize the phone as a device plugged in. It's a crapshoot. And I figure if they went through all the trouble of doing this media/photo file transfer thing for XP, why didn't they just use a little more effort to make the SD card contents visible?
So...unless a third party develops something that will provide SD card content viewing and editing, I will just go the long route and move files from my PC to a flash drive to the Win 7 PC to the phone.

[Q] USB Mass storage options no longer work after root

Okay, So I am a pretty new user of android. However I am a technically minded person and used to jailbreak my iPhone all the time. I decided to go for a while without rooting my Galaxy note II to see what the experience was like without root. However I found that I came across the need to root for certain apps. So Using a Windows PC I rooted with Odin. Now, on My mac, I can no longer connect to samsung Kies, no software on my mac will see the phone. I remember that plugging in my device would usually show usb options in the notification bar and i could select media or mass storage. But now my device acts as if it's only charging and not connected to my mac. I'm not sure what went wrong but I have been rooted for about 5 hours and it went pretty smoothly. So I really don't see why my phone will no longer mount to my mac as storage to enable me to use samsung kies.
Any help is really appreciated.
The only other info I can think of giving is that I'm running OS X 10.8.2.

Try googling for "SGS3 Easy UMS". It will load your SD card as an external drive and should work on the Mac.
This won't help for Kies though. Never used it and probably never will. It's dreadful.
Keith

Unfortunately, mass storage was removed by Samsung in s3 and note 2. Your root has nothing to do with it.
Also I'm not sure why you would need Kies, which is a terrible piece of software. Assuming you know how to root your phone using odin, you should know how to flash firmware using it as well.

It will appear if u enable usb debugging under developed options. Don't know why...

Am i missig something here? when i plug my phone to my pc it is automatically recognized [able to transfer files] without even needing to turn on usb storage on through the taskbar.

Of course you're still able to transfer files regularly back and forth from and to the PC, just on an MTP connection, not mass storage.

RESOLVED!
Okay, Maybe I had my terminology a Little wrong. But I still managed to correct the problem. The issue was that my mac was not seeing the phone at all because the USB Settings in PhoneUtil accessed by dialing *#7284# in the phones keypad, was set to Modem rather than PDA. Many thanks for your suggestions though. I hope this may help someone in the future.

[Q] Synch manager only synching phone storage

Hi Forum members,
I have a HTC One X with JB. Since the latest Synch Manager (SM) I am not able to synch anything other than Phone Storage. This is because SM doesn't see anything else. At the same time in Explorer I have a folder Internal Storage. This is the folder I also want to synch (partly). So now I can't synch music and pictures, because they are on the Internal Storage.
Anybody has any ideas how to resolve this?
Furthermore before JB I could choose what to do when I connected to my PC: only charge; use as HD; synchronize; tethering and another option. Now I don't have that possibility and tapping "USB connected" on the 'drop down' list only gives the option to change settings for tethering.
Ones again: anybody has any ideas how to resolve this?
Greetings,
Zooi

Did you update SM to the latest version ?

Yes, I have version 1.1.65.0 and the program tells me I have the latest version.

Uninstall and reinstall maybe ? Or you could mount the device in Recovery Mode so it appears as USB Mass Storage instead of MTP

After uninstalling I downloaded the latest version from the HTC website. This appeared a new version: 1.1.66.0!
Now the SM not even detects the phone :crying:, let alone finds the Phone storage or the Internal storage. So nothing is synched and I still cannot change the mode on my phone from "Charge only" (I think, for I can't see in what way the phone is connected to the PC) to "Synchronize".
I also switched the phone off and back on again, but it changed nothing.
In "My Computer" I can see the phone, but only the Internal Storage. Where is the Phone Storage?
So I'm still not able to synch the phone in the SM program. Suggestions anybody?

No idea on your first question, but the above behaviour is normal. In Android 4.1 (and above) MTP is used to connect to the device rather than mounting it as USB storage. The only way to connect it as a mounted USB storage device is to do it in recovery (as someone already suggested).

But the recovery mode can only be accessed through a rooted device? Mine isn't rooted.

Yes, sorry. Assumed since you were posting on here you'd be rooted.
Anyway, try this: http://forum.xda-developers.com/showthread.php?p=34660458
Still uses MTP but reading the thread it sounds like it'll let you access internal storage. I've not tried it since I'm not on Windows anyway, but might be worth a shot.

Same here sync manager does not work on mine. However, windows media player work fine.
I just install the sync manager for the driver.

Thank you all so far for trying to help. Nothing worked, so I still can't access the phone storage and SM doesn't synch other files than music and pictures.I guess I have to manually copy files from internal storage to my PC.
Greetz,

So what is the trick if this has been ticked the whole time but still won't show up? I've glot CM 10.2, MTP is checked, when plugged in the laptop it shows up at the bottom on the task bar & then when I right click it says Nexus 7.
My device shows up under devices & printers, but not under computer when clicking the start menu on the PC & clicking computer. My HDD, DVD drive & SD card all show up, but no N7 so I can't transfer files.
Am I missing something else?

Please elaborate a bit. What I understood is :
Nexus 7 doesnot show up like an SD card etc but as a mobile device yet you can not transfer stuff ?
It doesnot show up like a drive. For me, on Windows 7, it shows up like a mobile device in other devices with the name "Nexus 7". If i click it , I get into the internal memory. You can not rename folders or transfer files within Nexus(as it is used by the Nexus itself so it can not be changed). However, try copy a file from PC to your nexus. Does that work? If yes, that is perfectly normal. Use a file explorer like ES file explorer to rename and transfer files within Nexus. But Es file explorer has some bugs with JB 4.3 esp with extracting a rar file.
If this doesnot solve it, I remember there was also some settings for it. I can not remember though as I havenot used the latest CM 10.2.

So the first picture is of devices. You can see the N7 is shown, but clicking it only takes me to the info about the device. No way to transfer stuff. Right clicking gives me eject, troubleshoot, properties.
The second is the windows section where it shows the HDD, etc. No N7. I was expecting it to show up to be able to transfer files from computer to the device as in a mass storage device. I did this with the last one where I could see everything on the device.
I have a 600mb file I want to transfer to the tablet & was expecting to just copy it over.

I am attaching my pictures how I see my nexus when it is connected. You do not see Nexus 7 if it is not connected properly or not enabled from Nexus settings.
Does your device charge when you connect to the PC ?
Does your device connect in USB debugging mode ?
Further, go into device manager in My computers and see if there are any question marks on any device? Make sure your device is connected at that time.
Try to connect it to different port or without USB hub if you are using as sometimes, devices do not show up.
Moreover, try to connect your device to the PC and then tick on MTP and then change few options like connect via different methods and see if any usb connection is seen ?
Also, close all other mobile softwares in the background and taskbar (Kies, Sony PC companion, LG, Nokia PC suit) and then try connecting it.
They are many a times culprits. Even try uninstalling their drivers and programmes.
IF USB DEBBUGGING WORKS AND CHARGING, DRIVERS ARE PERFECTLY INSTALLED IN THE PC
YOUR PROBLEM SEEMS TO ME FROM NEXUS SETTINGS.
IT SIMPLY COULD BE A BUG AS CM is still nightly
I hope this helps

May be a CM bug. I just connected my Galaxy Nexus running 4.2.2 AOKP & I just transferred files from my phone to computer.
The N7 is connected, charging, debugging works, etc. So i'll keep waiting to see what the deal is with each new CM install.
I do appreciate all of the suggestions. Should have tested it on CleanRom before flashing CM to see if it was working then.

I am having the same problem with cleanrom
