Can't access the SD card via usb.

At first it actually worked and I got a few apks loaded up, but now it absolutely won't cooperate and I have been wrestling with this all night. Getting various errors, basically the PC just won't recognize either the phone or the SD card. Can anyone help me out here?

don't move apps to the sdcard.
uninstall whatever apps you moved to sdcard, reboot, reinstall them and keep them in internal memory.

I didn't move any apps to my SD card. I installed them from it. They were apk files. Installed in internal memory.

Known issue. Mine will also just stop seeing the SD card randomly. I'll know it when the phone rings and the ringer is some default garbage instead of the ringer I had assigned from the SD card.
I've yet to see any actual working solution. Simply rebooting the phone will usually fix it for awhile. Will probably have to wait for a Moto update.

what class is the sdcard?
people have been having issues with class 10 cards (although i have not).
try backing up everything on the sdcard, go to settings > storage and format the sdcard using the phone. move your stuff back onto the card and see if the problem continues.

Been there done that. Mine is a class 4 Sandisk 16GB.

Make sure you don't have any apps on your SD card. When you plug in your USB cord in it unmounts the SD card. If you have any apps on the card that are running is when you run into the problems being described as the phone is trying to unmount the card but can't due to the apps running.

Card is the stock 2gb, don't know what class.
No apps running from the card. Tried rebooting the phone a few times, turning USB debugging on and off, using different connection modes... No dice.

Def keep USB debugging on. When you plug your phone in does the USB icon show up in the notification bar?

Yeah, it does. And it charges.

OK grab the USB icon and pull it down just like a notification. You should see either 3 or 4 options, charge only, windows media share, etc. Sounds like you have charge only picked. Choose the media or data one and hopefully that will get you squared away

If u pull the card you should see a number on it in a tiny circle, the number in that circle indicates what class the card is. I had this problem once, after I rooted. Did factory reset and its been all good since....this was 2 weeks ago.

I've tried all the USB connection options multiple times.

I had to uninstall moto drivers and then reinstall them on my pc. All was good after that.

Also done that multiple times.
For now I'm just using my ghetto rigged card reader - digital camera and micro sd-sd adapter. Hahahha.
Probably just going to have to wait for an update and some more moto support for this phone on the pc side. Speaking of updates, this phone's been out for a month. Getting to be about time we at least saw a few bug fixes.

I'm sure you did a battery pull. I just went through this with my device, and that fixed the issue...

Actually, I didn't.

It seems that if there are any apps installed on the sdcard, it can't be accessed via usb.

Mine actually just started doing this as well. It was working fine, and now I cannot get it to mount as a mass storage drive on several different computers. I had three apps installed on the card, all games. I uninstalled all of them and still no mass storage.

So I've been making sure no apps get installed on my sd, or even any app databases because sometimes an app will install internally, but put its database on the sd. So none of that! I enjoyed a few days of being able to use usb mass storage, then a couple days ago it became inaccessible again. I checked for apps that may have slipped something onto the sd but didn't find anything noteworthy.
I left the issue alone, praying for a fix materialize from the etherworld, when something interesting happened today. I unmounted the sd and installed a new app, and a notification came up saying the app could be moved to the sd; but the notification used a wierd sound to alert me, presumably because it couldn't find the default audio file on the unmounted sd. So I then wen't to settings/sounds...oops... android crashed and rebooted with the sd card mounted; and I have access to usb mass storage again. Prayer answered?

[Q] Apps gone

Hi after having to switch my phone off, when I turned it on again it appears that all the apps I moved to the SD card are no longer there. I have just spent some time downloading them from the market again.
Question is why has this happened and how do I stop it from happening again
Thanks in advance

Solution
Hi Nexus.
I think you'll find that the apps still exist, they're just fragmented on the SD
card. This has happened to me plenty of times.
I've found it's only apps that are installed on the SD card and it's never
happened with apps on the phone's internal ROM.
A good way to check is to go into: Settings- Applications- Manage applications-
then tap the SD card tab. That list shows all of your apps installed on the SD
card. I found that when apps here got fragmented/corrupt they didn't show their
original app icon. Instead they showed the stock android app icon. This is a good
way to tell if the missing apps in question are still there but are just fragmented.
The way to solve this, the way that's worked for me, is to plug the phone into a
pc and mount the SD card as a disk. Then on the PC access the SD card via
explorer and right click- properties- tools- then click de-fragment.
This may take up to 30 mins as it's not as fast as a HDD.
From using this technique my apps have always returned and I can use them
with no problems again.
I've also noticed that this issue only happens if I restart or turn the phone off. I
don't understand what is corrupting the apps as the SD card is mounted
correctly and is the one supplied as standard.
I hope I've helped, and I guess this will save you from re-downloading all of your
apps again.
I'm happy to hear anyone's thoughts/suggestions onto why this is actually
happening in the first place too.
Cheers, Dms

Hi thanks so much for the answer. This has been bugging me for ages and even though I have been searching I have not had any joy solving it until your reply.
As you said it only seems to happen to apps on the sd card, and I would like to know why they are not "persistent" There must be a developer who understands the Android system who can explain why this happens and what you can do to make apps you have on your sd card permanent.
As you said it only happens to me when I re start my phone.
Thanks again for the answer

Hi. It's no problem. Yes I havn't seen anything about this issue being mentioned either.
I'd like to know what's causing it. Whether it's a hardware fault or something in the software.
It's a real pain having to hook it up to my pc to sort it out. Especially when I'm away from a pc, I can't use half of my apps.

[Q] Cannot delete or add to SD card

A few days ago, I tried taking some pictures with my Droid Charge and the pics would not save. I tried in the stock camera app and in CameraZoom EX. CameraZoom gave me an error message "failed to save photo to SD car (error code=2). I figured I was out of space.
My Titanium Backup scheduled backup did not run the next day. So, I assumed I was out of space.
I connected the phone to my PC and deleted some pics and music. WHen I was in WIndows explorer, it said I had about 2 GB free after doing all of this.
When playing music today, I noticed files that I had deleted before still present on the phone. I thought this was weird. I went back and checked and all the stuff I thought I deleted was still there.
I searched on the CameraZoom EX error code 2. It directed to remove and reinsert the card and reboot. I tried that. I have tried unmounting and then mounting with no success either.
My phone seems to be working fine, but I cannot delete or add anything to the microSD card (the original that came with the phone). It does not matter if I use my WIndows 7 laptop, desktop, or various file managers on the phone itself.
ANy idea what is going on?

To me, it sounds like the SD card is going bad. Not a common occurrence but it can happen. You're lucky you can still read from it... I would suggest getting a new SD card (Verizon might even give you a new one free) and copying your data to it before sectors start going bad. By the way, how did you manage to full up 32 gb?
Or I could be blowing this out of proportion and it's just a matter of write protection on the card.

Another option is to copy everything off the SD card, format it, and try to write everything back. Sometimes a format can joggle a bugged card.

It is mostly music that I have on there. I am not sure how write protection would have gotten on the microSD card or how I would remove it. It does not have a physical togge like an SD card does.
I think I may have to try re-formatting. Ugh.

Corrupted SD card. Call VZW and be nice on the phone, explain the situation, hopefully they send you a new one.

Hmmm, this is interesting. I cannot even format the microSD card. I tried to do it through Windows Explorer. It looked like it worked. I then tried to copy files back on and it choked halfway through on a movie, I think.
Anyway, what was more interesting is that when I looked at the drive again, everything was back where it originally was. So, the re-formatting must not have actually worked.
I then tried to erase the SD through the options in Android. I unmounted. I then selected Erase SD card. After rebooting (to just be safe), the SD card still is untouched.
THis microSD card has become an impenetrable force. More realistically, it must have write-protection enabled somehow as that is the only thing I can think of.
The question is how do I find out if write protection is enabled and how to disable it? Any ideas are appreciated. Thanks.

[Q] Help with SD card

I was wondering if anyone has any ideas or can point me in the right direction to solve this. Yesterday I started getting messages that the apps that were installed on my sd card stopped working...........then the gallery was gone (all my pics) now there's a message in the corner that says Blank SD card......(card is bland or has unsupported filesystem) do you want to format...........I've tried taking the card out and plugging into a PC however it says its a read-only. I don't want to format, is there any way to get all my pics and data back
any help is appreciated

Unfortunately this is mostly a lost cause. This is a known issue on the Galaxy S3, and I've heard a couple of other phones as well, including the Note 2. I've had this happen THREE times on my phone, to the point that I just don't even use an SD card anymore.
From what I've read the brand and size of the SD card doesn't make a difference.
You may be able to recover some of your pics and other files by using file recovery software on your computer. I used a program called Pandora Recovery, and while it spit out the files using different random names, at least I got a majority of my pics back (I had over 1000 on the card).
Beyond that there is no way to recover the data on the card. Once you try recovery software, you'll have to let your phone format the card if you want to use it again. Even Windows won't read the data from the card in it's current state.

Thank you for your help........im going to give Pandora a try and see what happens. I did hear about a program called DiskDigger Pro........so wish me luck..........I wish I was more pro active in reconizing the signs but it just happened out of no where

I believe you should able to cause it happened to me a few times and I able to recover all my stuff (videos, photos). The trick is find a good SDcard recovery software.

This may or may not help, but it's worth a shot.......http://forum.xda-developers.com/showthread.php?t=367912&page=2

This problem is why I will not be buying Samsung phones again. It is BS that I can't even use my 32GB SD card because it will eventually fail I will lose everything on it. It has happened twice in 7 months with the phone already.

disk digger worked great for me except for the occasional corrupt. You have to format first.

Thanks a lot for sharing information about other products. However, while scanning the corrupt SD card encountering error messages and unable to recover entire data. In order to overcome such problems, use Remo Recover tool to restore data from corrupt or formatted SD card.

Just wanted to let you guys know that my old SD cards got corrupted because I tried to configure the metadata of my songs through such apps like player pro and etc. I have a 64gb right now and its been working fine for over a year because I just manually configure everything when I connect it to my computer.

(solved) Big external micro sd card issues

I am getting an error, old as android itself, with my new s7 Exynos. "The device has either stopped responding or has been disconnected". This happens when I try to copy my 25 gb music library on external sd card. I tried all usual stuff like:
- Use different cables
- Reinstall samsung drivers via Kies
- Transfer using MTP or PTP
- Use USB Debugging on and Stay awake option on
- Tried pushing folder via ADB push command, but it says "Read-only file system" when I typed location as /sdcard1 (which I think is an extSdcard right? It did copy a .txt file if I typed just /sdcard but that is internal storage)
- Tried with Samsungs own SmartSwitch but the bloody thing doesn't even have an option to copy files to device (only backup and restore), and Kies is not supported for S7.
On side note, the same sd card worked perfectly with my S3 and gave no errors. When I inserted sd card into S7, I formatted it inside the device. What other troubleshooting stuff should I do? I can't believe that this crap is still an issue. Why can't we have our USB Mass Storage back?
-----------------------------
Big edit:
Ok my phone doesn't seem to like this sdcard. I inserted microsd card to my s3 and copied 17 gb of files, to check if there is a problem with MTP connection or sdcard, but it copied all 17 gb of files without any errors or problems. I checked on phone if it reads correctly, and all music plays fine instantly without any lag or freez. But when I inserted this micro sdcard back into my s7, there was a massive lag/freezes. When I click "MyFiles" or "SolidExplorer", or any other file manager, there is a big lag/freeze, and file manager never opens (it is always stuck). Also, when I go into settings and when I press "unmount" under storage, nothing happens. When I press home, it doesnt go to home screen, and says that touchwizz is not responding (if I change default applications to Nova launcher, it does go to the homescreen though). When I try to open Shealth app, it doesnt open it. Also when I put my phone to sleep, I have to wait like 10 seconds for screen to turn off sometimes. When I pop out sdcard though, all the problems go away INSTANTLY. Everything is smooth again and responsive, file manager opens, shealth opens, everything works like it should. If I insert sd card back in, same problems happen.
And as a cherry on the cake, I put sdcard back into my s3, and everything still works fine. All files are readable, music playes, etc.
When I was searching online, this is the closest thing I have found that explains my problems, but there was no solution: http://forums.androidcentral.com/samsung-galaxy-note-4/542854-sd-card-freezes-note-4-a.html
Anyone ever experienced anything similar?
EDIT: Luckly, it was not my phone fault. It was my sd card. Even though it worked fine on s3 and my friends s5, it didn't work in s7 for some reason. I purchased samsung evo+ and it works flawlessly.

try format as exfat ?

Can't, it is 32gb card and it is not allowing me. Also, sometimes when I insert it, the whole phone freezes complitely. Once I even had to use volume down + power button for 10 seconds reset method since it froze complitely. Card is in fat32.
edit: I also tried copying files from USB flash drive (adata 64gb exFat) to sdcard directly on my phone, via OTG cable. It also stopped the process midway and phone wouldn't enter into any file storage (it froze). I had to remove sdcard again and insert it back in to remove that freezing.
edit2: I copied 17gb folder full of subfolders to internal storage, and it transferred without any problems and pretty fast (about 20 minutes). That means MTP connection and drivers are fine. When I tried copying the same 17gb folder to external sd card, "device stopped responding or has been disconnected" error again.

It seems like this is a lot bigger problem, as this is not really an issue about "device stopped responding" anymore. I edited first post. Still looking for solution.

Search the forums, this is a known issue with some phones. You can try other cards, sometimes that will help. Or get your phone replaced as it's a hardware defect. My first S7 was like that. This one reads sdcard without issues (but has radio issues).
