Can't Mount SD Card

Hey Everyone,
I apologise if this is in the wrong forum (not sure if it should be in Android Development), and before I start I want to make it clear that I DID use the search function, I searched for "Can't Enable USB Mass Storage" and "No option to mount SD Card" with no relevant results.
Rom: JFv1.51 CRB43-EU
Ok, I was using my phone fine I managed to sync around 12GB worth of music and transfer a few files last night (I flashed the ROM around 20:00 GMT after trying out several hero builds).
This morning I mounted the SD Card to my laptop (OS is Windows 7 RC1) and transferred a few APK's. Suddenly as I was in the market the phone comes up with "Checking SD Card for Errors" and had for some reason unmounted itself from the PC.
Now when I plug in the USB cable all I get is the light to indicate it's charging. There's no option to mount the SD Card. I've tried it on my Laptop, My Vista Desktop AND My Xbox 360 (usually there's a mount option when you connect to that which allows the xbox to see music on the phone).
Strangest thing is the MicroSD Card seems fine, I am able to play my music and see the 2 pictures I have stored on it. Another site suggested using Anycut to make a shortcut to SD CArd and then ticking Enable USB Mass Storage. This doesn't work either, I get a ! in a triangle in the status bar saying USB Mass Storage Enabled but neither my laptop or my desktop will pick it up.
Any Suggestions?
Thanks,
Steve.

Yep, Should it be?

Yes it should be. Try uninstalling and reinstalling the drivers (USB mass storage devices)

Edit: Double pOst

[Q] USB Mass Storage mode only for reading ?

I'm the only one having problems with usb mass storage? With all builds from all chef and all kernels it happens the same. I can read from the pc what is on the SD, but if I copy a file Android dont see it , the file size is 0. And new files created in android can't be readed by windows either (I can only read the files that were written on the SD before the last android boot)
I missing something? I tryied dismounting the SD from android with same results
Are you using it in the same way USB MASS STORAGE in WM6.5 ???

I use USB storage all the time and in every andrioid build I've used(about 20) I've never had any problems. There are many people like me that also have no problems, but there are also many like you that have plenty of problems. I'm not sure that anyone really knows why.

Thanks for answering. Do you have 2 partitions on the sd ?

Just want to check a few things:
1: you plug in via usb and select "disk drive"
2: you are not still connected via usb when trying to read the items on the sd card?
3: When you disconnect the usb, you use the usual method (right click the icon in the taskbar and select "safely remove hardware") then wait for the SD card to be prepared by android before accessing it?
Also, how are you accessing the files in Android?

1 & 2: Yes. Windows assing the drive letter and can read it fine.
3: I connect Android to pc, choose USB MASS STORAGE, in windows access the new drive letter, rename a file , choose "safele remove hardware", disconnect the cable, wait for Android to "prepare the sd" , go to the file and it has the old name!!! the weird thing is that if I connect to the pc again, I see in the pc the new name!
Is like Android is working with his own FAT32 table IN MEMORY and not refreshing it.
I tried Ghost Commander/ES file manager/Root Explorer, all with the same results.
PD: I found something else... If I DISMOUNT the SD from Android Im still able to access it with ES File Manager,etc. So its not really dismounting it Why can this be happening with all builds/roms?

I have the same problem. Strange thing is it worked fine fore the first couple of days. Anybody have a solution?

Try using "Rescan Media" app after you copy your files to the SD

Still nothing. I have to boot back into winMo to transfer files to my SD card! This is really annoying,

Plenty of other tools provide media scan as well, like Optimize toolbox, Switch pro widget and more. they all worked for me.
[edit] sorry, optimize toolbox doesn't offer it, it just clears the cache :/
power control plus however has this function as well.

[Q] "Internal Phone Storage is Unmounted"

I have a rooted Atrix 4G and I am having a very weird problem with it.
If I go into Settings->SD Card & Phone Storage while no USB is connected it shows the following:
Code:
[B][SIZE="2"]Internal Phone Storage (media area)[/SIZE][/B]
[B]Total Space[/B] - 10.71GB
[B]Available Space[/B] - 10.60GB
[B]Unmount Internal Phone Storage[/B] (selectable option)
[B]Format Internal Phone Storage[/B] (grayed out/unselectable)
Makes sense... all is good right? Until I plug in USB (debugging mode selected, USB mass storage for connection type). The Notification bar shows:
Code:
[B][SIZE="4"]Ongoing[/SIZE]
USB debugging connected[/B]
Select to disable USB debugging
[B]USB connection[/B]
Select to manage your USB connection
[B][SIZE="4"]Notifications[/SIZE]
Internal phone storage is unmounted[/B]
Internal phone storage is unmounted
Going into Settings->SD Card & Phone Storage now shows:
Code:
Internal Phone Storage (media area)
Total Space - Unavailable
Available Space - Unavailable
Unmount Internal Phone Storage (grayed out/unselectable)
Format Internal Phone Storage (grayed out/unselectable)
What is going on, and how can I get it to mount the internal storage while connected with USB debugging?

Instead of "USB Mass Storage", "Motorola Phone Portal", or "Windows Media Sync" choose "None".

Internal Phone Storage is Unmounted - Motorola Atrix
Having the same problem. Seems like when you power off and reboot the phone, while still connected through the USB port, the problem goes away, but I am not really sure. Help would be appreciated.

I got the same message but it wasn't connected via usb yet i've tried to mount the internal thru recovery settings but it keeps going back yo being unmounted

Do what he said!
Pull down notification bar > select USB connection > Select None

hello i to had this problem but after messing around with different settings i tried to start from the begining so that didnt work and then i wiped everything and i do mean everything if it could be wiped i wiped it clean and installed my download rom i had gotten and still didnt work but i wiped it again and did this 3 times in a row and installed my rom again and it worked so try wiping everything and about 3 times and install a custom rom and see if that works

FIS
The best way to fix it is too... first all the apps from the internal storage... the once that you cannot uninstall move the app and then uninstall and use the format option.. it will def. do it... i had the same problem but in the end it worked.

Blank SD Card in Media Transfer Mode...

Can anyone tell me why when I connect in Media Transfer Mode, my SD Card reads as blank in Windows. Windows detects the phone AND the memory card but it is blank. You can create folder, files etc on the blank card but they dissapear also.
However, if you connect the phone in Mass Storage Mode or remove the card and plug it into PC, everything works fine. The card also works fine in the phone.
Windows 7. 16GB Card that came with the Play.
ps. the card data usage is reading as correct even though I can't see anything on it in Media Transfer Mode.

reinstall pc companion check my thread about mtp app it should explain everything on how to bring back everything
The blank problem is because the driver are not correctly installed.

Ok, thankyou.

Weird, followed your excellent thread and done a reinstall but still blank.

yeah weird... you are sure that everything is available on mass storage mode ?
if it's the case then maybe your data are hidden on the device...
Check if there is folder without a dot at the start of the name (non hidden folder)
put new files and see what happen
Run a chkdisk on your SDcard with windows on mass storage mode
get andexplorer and check if everything is available through this app
windows might be infected by a virus that put your SD in a weird state
do a virus check...
Last if nothing above works: media transfer mode on your xplay> go to printer and other device on PC > right click > properties > hardware tab > properties > driver > uninstall driver > follow mtp app guide again to reinstall the driver
after that report back here

Yep, all there. Phone is also detected fine in Media Transfer Mode in PC Companion (as R800).
Will do the rest when I get a moment, thanks for the help.

- I did this in Mass Storage mode and it works normally.

- Done, it is fine. I used Astro and all is there.

do a virus check...
- Clean.
Last if nothing above works: media transfer mode on your xplay> go to printer and other device on PC > right click > properties > hardware tab > properties > driver > uninstall driver > follow mtp app guide again to reinstall the driver
after that report back here
- Done this, the driver reinstalled but still blank SD card in Media Transfer Mode.

I'm doomed to use Mass Storage Mode!

Why doomed?
You want to get files from your PC or laptop to your Play, right?
That's what mass storage mode is for. That's what I use.
The only time I need to be in media transfer mode is to communicate with the Play with adb, having nothing to do with the SD card.
What exactly do you want here??

Maybe he didn't figure out how to mount the sd card to after choosing mass storage mode.
Remember you need to mount SD for accessing the file on the computer after setting mass storage mode

Ok, I guess it is not that big of a deal. Was just curious to getting it working as it should. It's not really gonna impact me.
Thanks for all your help kenshindono, your info and posts are very helpful.
Unlike DeadlyDazza who seems continuously rude and obnoxious.

Not really, i could understand if you had a crippling problem which prevented you from connecting your device for transfers.
But that's what mass storage mode is for, as far as I know, media transfer mode is for pushing with adb & using SE's media transfer PC software.

Please reply seniors members Downgrading MM to LP not working

Dear All
I am not able to access phone internal storage and SD card of my phone from my laptop (Windows 8.1), after downgrading my Lenovo k4 note from MM to LP (A7010a48_S152_160302_ROW).
USB computer connection options of my phone when I am
1) connecting to Media device then -> it is showing CD drive of Lenovo suite, not able to see both internal and external storage in laptop
2) connecting to Camera (PTP) then -> laptop showing DCIM folder and another pic folder of both internal and external storage, but I can transfer only pics & video, still not able to see both storages.
I am not able to see both storages Int & SD card but able to see both internal and external storage of my phone to other PC like windows 7. But it is not visible on my laptop which is running on win 8.1. Earlier on LP version, I am able to see both storages on my PC.
I had not formatted my SD card at the time of downgrading to LP and removed sd card before downgrading may be it is the problem but other PC both storage are visible, then I tried again to downgrade again after formatting SD card, but did not get success.
Nothing happened when I was retrying to downgrade again LP version updated device, flash tool screen freeze when I clicked download button (I have chosen Firm ware upgrade and Download only both options. I have checked the logs please provide solutions.
