I just updated to the recent Gingerbread release (2.3.3, LG-P999-V21e) and it seems to have broken my SD Card connectivity on my G2x.
I have a 16GB SD card mounted on my phone, but when I'm connected to my PC via USB and try to "Turn on USB storage" I get the spinning loading icon for about 10 seconds I then get notified that my SD card has been unmounted in the notification bar. If I leave it unmounted and try to connect again, it connects fine, but I don't have access to the unmounted SD card. I've tried remounting it, and get the same results.
I don't have DoubleTwist or Winamp installed. I've tried checking and unchecking "Mass storage only", and I've tried a different SD card. I also updated to the latest LG phone drivers before I updated the phone. I even reverted the phone back with the "factory data reset" with no luck. I'm at a total loss. It doesn't seem like any one else has had this problem since the update...so I might just be screwed.
Any help would be very much appreciated.
I had a similar problem, though with various ROMs. Pull your SD and back it up to your computer, then reformat it in your phone.
Both Internal and external SD have to be unmounted for the USB storage mode to work.
There you can access both from your computer.
That did it....THANKS!
I'am having the same problem on my HTC Sensation running CM 10.2.
How do you unmount internal storage?
In cwm recovery. Go to mounts and storage. Unmount/mount internal storage

Hi all. After updating my i897 via kies yesterday, all went well.. I re-rooted and phone is working as it should. However, I just went into "Settings... SD card and phone storage" and noticed something strange. For my External SD card, I have the usual options "Total space", "Available space", Unmount SD card", and "Format SD card". The only one highlighted is "Umount SD card". HOWEVER.. on the Internal SD card, I only have "Total space", "Available space", and "Format SD Card" (which is highlighted!). No option to "Mount/Unmount". so two concerns... why is the "Format SD card" highlighted...seems risky... and where did the option to Mount/Unmount" go? It's disconnected from PC and has been rebooted, but still shows this. Thanks for your help.
Yep I have the same thing and I am running Cog 4
And why here is something wrong?

With USB Debugging On or Off... it's the same. images attached.
Mine has the option to unmount the external card, however it locked up last time I tried. Using KB1.

if you have your usb cord plug in to your pc and phone. on the screen that you slide down doesnt it have a place to mount your card there . my says usb connected hit that and it mounts both cards to add stuff to the cards.
As the tittle says, my external SD card will no longer mount to my computer. The internal mounts just fine. I can see the external using a file explorer when USB mass storage isn't connected. I use my external card as a "thumbdrive" constantly and it has always mounted just fine, this just cropped up today.
I am running Bionix2 if that makes a difference.
What can I try to get it mounting properly again?
UPDATE:
I have tried turning on and off USB debugging
I have tried pulling the SD card, booting, turning back off, reinserting the SD card and booting again.
I have tried uninstalling the LG driver from the computer and reinstalling it (ADB)
None of these have worked.
The empty drive shows up in "computer" as a drive, the SD card just never mounts to it. When USB mass storage is ON the SD card definitely unmounts from the phone.
This is very frustrating as I need some files off the card and I don't have access to a micro SD card reader.
UPDATE2:
Got the files I needed by copying them from the external card to the internal card, connecting, mounting and copying them from the internal card to my computer. It is still a PITA though not as urgent as it was.
So last night I pulled the SD card, copied everything off and formatted it on my computer, didn't change a thing. I was then going to reload the ROM I am using. This didn't work as I am running external CWM recovery and it wouldn't mount the SD card either.
As a last effort before trying another card, I formatted (erase=format?) the card through Android. Everything seems to work fine again. I copied everything back to the SD card without an issue. CWM sees it again as well.
What could have caused the card to spontaneously need to be reformatted through Android after working perfectly well for 2 months?

I had the same issue, I think when you install different roms some use different ext for the drives, thats why its critical that after each rom you wipe wipe wipe, and as we know now, lol format sd card
I have been trying to fix this problem for a few hours now with not result.
Last night I went from an one click unbricked stock rom on my infuse to CM10.
Before CM10:
Normally when I plugged the phone into my computer two removable drives would be recognized by my computer but would not be accessible until I triggered the USB storage from the phone. When I do that I would have access to the 16gig internal SD card on the phone which is now sdcard0 and I would also have had access to the 32gig external SD card that I have in the expansion port.
Now:
My computer still has two removable drives pop up when the phone is plugged into the computer. However I can only get into the internal SD card on the phone. When I click the Removable Disk H icon for my external 32 gig SD or sdcard1 I get a please insert disk error.
To sum it up. I am able to transfer files back and forth between the two disks on the phone. I can access everything on each SD card. I still have an external_sd in the file list but it is now just a folder with a few files in it instead of the external sd cards contents being there on the stock rom. For some reason the phone isn't mounting the sdcard1 as its own removable drive when I connect USB storage to my computer.
I am going to continue looking for an answer on my own in addition to what ever help I receive here
Thanks for reading in advance.
I flashed Beanstalk and CM10.1 and after every reboot my internal sd card is not recognized at all. My external sd is still showing up if I go into it. I wiped/flashed so many times that I am still having the same problems. May be I should stick to Gingerbread until my next upgrade. Here are some photos.

I found a temporary fix that is to fix permissions in the recovery.
internal storage won't re-mount after usb mass storage disconnect

I have the same issue here, even though I done the fix permission thing it still boots up with the internal storage not mounted, one solution here was for me to plug in the phone in for usb storage and when it prompted usb connection click on it and let it load, then disconnect and eject the usb mass storage from the computer, then unplug and disconnect usb mass storage from phone, the phone then scans for both internal and external sd cards, you then have access to both SD cards, but this is just a temporary fix to my issues as well.
My problem here is that when the phone recognize both card and plugging the phone into usb storage and removing it the internal sd card won't mount back but external stays mounted, I can't find a fix to this issues, I've searched around and can't find any answers. I've tried reformatting going back to stock, formatting systems, etc.
I'm currently on Carbon ROM, which by the way is one of the best ROM I've had, just that issue I'm having.

I moved the SD card into my PC and remove all contents. Format the SD card to Fat32 and then replace all my contents back on it. This worked for me. :good:
Last night, i factory reset my phone, backed everything up to my external sd card and spent most of today restoring all of my files. I had one folder on my computer of pictures and misc. backups left to go. I plugged my phone into my pc and tried to drag them over. I got an error saying my device has stopped responding or has disconnected. Quick google search and i installed an app that let me enable usb mass storage mode. Tried that and it did not work. I put my phone back on MTP mode and plugged into my computer, checked and literally my entire internal and all of my external storage is wiped. What do i do to get these files back? 90% of my backups were on my external card. My phone is a Verizon Galaxy s3 16gb with 16gb external sandisk sd card.
