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)

Phone loses SD card

Why does my phone lose the SD memory card when i plug it in to my computer?
as soon as i plug in the usb cable, my phone loses what ever is on the SD card, and when i unplug it, the phone recognizes it again..any ideas?
thanks

When you connect the phone to your computer the computer allows you to use it as a disk drive in which you can drag and drop files onto your device. For some reason while this is happening you can not access it through your phone.
Next time you plug your phone in to your computer and a window comes up asking for activesync, diskdrive etc, press nothing (the screen goes away after 5 seconds) your phone will be completely normal and charging nicely from the computer
happy ending isnt it?

use the phone with activesync and not as a disk drive. .

You have your usb mode set as "disk drive" on the phone.
When it's so, when you connect USB the card is unmounted from the phone's OS so that the PC has direct access to it.

thanks,
where can i change that option? Is it possible to have the phone plugged in to a PC and watch a movie or music off the SD card?

Yes, if you choose activesync mode, as he said above. It normally asks you everytime you plug the USB calbe, but you most likely chose disk drive and checked the "don't ask again" checkbox. You can change it on settings tab, menu->more, connections, USB to PC.

ok, so my next question is, does activesync support windowsXP 64?
thats what we use here at work, and its giving me error messages when i try to use activesync.

What errors?
By default under Windows the software used to manage phones, which is called Activesync on XP, or WMDC on Vista/7, is not installed.
So if you plug the phone in ActiveSync mode on a PC that doesn't have it you'll see missing driver errors. If all you want is to charge the phone you can just ignore them, if you want to access the card/internal memory contents you need to download and install it.

My problem is, when i connect phone to PC with activesync and disconnect it, its working properly after this and i can use SDcard, but when connect it to pc like disc drive after disconnection off cable my phone dont see sdcard. This happening after ROM upgrade from 1.48 to 1.66. Can somone help

Cant mount sd card on the computer

I hate to start a "OMG ITS NOT WORKING" Thread. But im just plain stuck.
Im trying to get to my sd card on my computer, to switch to my 4gb and to get the update.zip on it so i can root. But no matter what i do, it wont mount. My computer complains that the "USB Device not recognized" and loads a bogus driver. Ive been trying to get it figured out but nothing so far.
Anyone else have this problem? Any one know how to fix it?

hope this helps

No help :O( i dont get whats wrong.

what happens when you plug in the usb cord? Are any external drives shown on your computers file/drive viewer (my computer, etc)? If so can you open those drives, if not what does it say?
the way it should work is.
-DL the drivers here - http://forum.xda-developers.com/showthread.php?p=7218057
-install the drivers on your PC
-hookup phone to PC via the provided usb cable
-on the phone drop down the notification bar and MOUNT the SD card.
-open My Computer or other file viewer
-see two external drives one the internal with about 13GB of total space and one the SD card with 2GB of total space
-add remove files from cards

I did all that. When i plug it in, my computer says "the usb device is not recognized" and proceeds to load a bogus driver. Ive installed the debugging driver, nothing. nothing shows up in my computer for the sd card, OR the phones own flash memory.
I have 3 separate android phones, never had this problem before.

try connecting the phone to your pc again. Make sure that on your phone, that youre using the mass-storage option. Next look at the top of your phone, and pull down the header bar. and click on the "usb connected" option or whatever it says, and then choose "mount" when it pops up.
That's how your actually turn on the mass-storage. dont know why its like this, thought it would be automatically done after chosing the mass-storage option.

I am having the same issue. Installed drivers but can't access the drives.

It does automatically set it self for mass storage, but the computer for some reason isnt seeing it. im pretty sure its a driver issue. or the usb port on the phone maybe bad... that would be annoying.

[Q] Mass Storage showing 0bytes drive

Hello everyone, when i connect my phone to the computer and select mass storage device, my computer shows 2 new drives, but both have 0bytes capacity. One is for the microsd card (which i don't have installed) and the other should be the internal memory, but both show 0bytes, and i can't access neither of them. Any idea why this could be? I tried it on several computers, all of them running windows XP 32b professional. All the other connection methods work, i can even access internal memory using kies mode.

i am sure this has been covered a few times but:
1. plug in usb
2. select mass storage
3. on sgs pull down notification bar
4. click usb
it will now mount your sd cards for use
seems like a pointless step to me but hey i am sure there is a reason somwhere

I believe the reason is so that we won't have two separate device: pc and i9000 accessing (mounting) the sd at the same time. Might cause havoc to the file system.

[Q] Computer Doesn't See USB

I am running CM10.1 from a mSD card. When I connect my NC to my computer via USB cable it isn't recognized. The NC is recognized with the mSD card out of the NC and booted into the NC's OS. Computer OS is Linux. I ran fdisk -l just to check and card in it is not seen. Is the NC recognized only with no card in or what. The CM10 was unlocked. I wanted to transfer some book files over. Will I have to pull the card and plug it into my computer?

Try going into settings > storage > USB computer connection and make sure that your device isn't showing up as a Media Device (MTP).
In other words, ensure that your device is being mounted as a Mass storage device.

Thank you for the answer but I suspect that was a Windows answer not a Linux answer but it gives me a place to start looking. I'll try running running "lsusb" again.

I meant to try inspecting the settings on your nook. Mass storage devices should appear irrespective of the computer platform. I've used my NC as a usb volume to move files to-and-from linux devices before.
Since you mention that the computer can see your NC as a storage device but not the SD card, it may be an issue with a setting on the NC (not the computer). Or not! One thing about linux is that there is quite a bit of variability between different users' setups.

Thanks for your patience. I do not show a USB computer connection in storage. What I did notice though maybe not related is that Unmount SD card and Erase SD card are grayed out when the USB cable is plugged in.

There should be a menu icon - 3 dots in the upper right in settings>storage

That did it thank you. It was set on MTP and I moved it to mass storage.
