When I plug my phone into the computer it actually shows up as two separate removable discs. The SD card is removable E and the phone is removable F. Hope this helps.

Make sure USB debugging is enabled. For whatever reason, on both android phones I've owned, my computer could only pick up sd cards with it enabled.
Second thought, if you're using a custom kernel, sometimes it can break USB. I remember morfic's kernel broke it back when I used Bionix 2

I had this problem a few days ago after I flashed the Trigger 2.3.4 gb rom coming from Ultimate 2.2 froyo rom..When I'd plug in my usb and try to mount the SD cards the phone would say the cards are mounted (even the icons for apps installed on the sd would go generic as if they were mounted) but the drives wouldn't show up on my pc for some reason. I never had that problem before so it drove me nuts until I finally got it resolved but for me it was multiple problems..Like the guy before me said always make sure usb debugging is turned on and this may or may not apply to you but if turning on usb debugging doesn't fix it get the LG update tool and install the drivers from inside there because they are the most current ones..I thought mine were the most current because I even redownloaded the drivers on LG's support site but those aren't the most current ones. Anyway hope this helps someone avoid the nightmare I went through!

sd card issue

so in voodoo recovery the sd card wont stop unmounting..as soon as i want to choose a a zip from sd card it will appeared unmounted as opposed to mounted..Now my pc cant read the phone when I connect to computer..any help?
it comes out as unknown device?

go into your settings and then to sd card. unmount it. remount it and then reboot into cwm and clear cache/dalvik. then reboot recovery and try whatever it is you were trying to do.
if that doesnt work, try the following:
try to format the sd card from your phone and then let it rebuild. then reclear your cache and fix permissions. do all of this before plugging it into the computer. on the computer, uninstall your current drivers. then reboot. reinstall. reboot. plug the phone into a different usb port. let it load on the computer. disconnect and then go into cwm and see if you have the problem. make sure to back up your pics and whatnot before the format.
just a reminder, you should always eject the phone on the computer and turn off the connection on the phone before unplugging the usb cable. i think this is what happened to you and corrupted some things.

it says unknown volume path sd ext..so it didn't let me clear dalvid cache..i try partitioning the sd card ..then factory reset could that be itt why its not letting me?

It probably did clear your dalvik. That error only means you do not have an ext partition on your sd card. It can't clear something that isn't there. Dsexton has instructions in the bible to create the partition. Did your computer recognize the phone after you did all of that?

Use the sdcard adapter and hopfully you have an sdslot on you computer. Put it in there and format it from the PC also do not do a quick format and set the allocation size to default. If you can get that done and get the phone to pick it up then format it again from there. Hope this helps and good luck ,let us know how it goes please

Have you tried to partition within cwm? Do atleast 1gb.
Edit:
Dissable lagfix for the sd card to be noticed

[Q] USB Mass Storage Not Working

So the USB mass storage functionality has stopped working. I've owned the same G2x since it came out. I tried in both stock Android (2.3.3) and CM7 build 152. I've tried attaching the phone to two different computers running two different OSs (Win7 x64 at work and OSX Lion at home) and using two different cables. `adb devices` doesn't show any devices attached, either, and I have "USB debugging" enabled. The G2x shows it's charging, so I know the cable's connected and receiving power from the USB bus. I'm gonna call T-Mobile (and/or LG) about it. Has anyone had the same issue? Does anyone know of anything I should try?

Did you install the LG drivers?

Download from LG here:
http://www.lg.com/us/mobile-phones/G2X-Driver/index.jsp

Yup, LG drivers are installed on Win7. No drivers needed for OSX.

Have you altered the mountpoints of your sdcard? I've noticed that in stock roms if I change the mount points of my sdcards then I can't mount them to my computer as mass storage.

Nope. But I guess I could format the SD card and internal memory. Only problem is that I have data I need to keep on it.

Did you try a different USB cable?

Yup. Tried three different cables from three different manufacturers.

Hmm I'm not sure what else to suggest then. Do you have clockworkmod recovery? Try booting into clockworkmod and go to Mounts & storage. Select to mount USB storage there and see if it mounts to your computer that way. If it mounts there then at least its not a hardware issue.

Doesn't work that way, either. I put in a new sd card and formatted the internal sd (emmc). I think I'll be making a trip to the T-Mobile store tomorrow. I'll probably need to put it completely back to stock, heh. I should be okay just to reflash the 2.3.3 update right from the LG tool, I think.

Happens to me from time to time. All I do is turn the USB debugging mode on and off and plug it in until it works.

I tried cycling usb debugging, too. Didn't work.

So I'm making a little bit of progress. I installed adbWireless and plugged in the USB cable. This is what `dmesg | tail` gives me:
Code:
<4>[ 2528.279492] -->> MUIC : Set_MAX14526_Usb_Mode_Detect
<4>[ 2537.679262] Dumb charger detected

I'm backing up my sd card through wireless adb by using `adb pull /sdcard/ sdcard`. I'll hit up t-mobile tomorrow and see what they can do for me. I'm hoping that I can still use the LG tool to flash 2.3.3 so I can be fully back to stock (uninstall clockworkmod). I'll keep you all updated in this thread. Meanwhile, if anyone has any more suggestions, I'd love to try them out.

Do you have an external sdcard in your phone? Just use a file explorer to copy all your data from the internal SD to the external one and then take it out and use a microsd adapter put it in your computer to get your files from it.
To return to stock you can also download the stock nandroid backup posted in the dev section. Its here:
http://forum.xda-developers.com/showthread.php?t=1196019
Download it to your computer, unzip it and copy the unzipped v21e folder to your external microsd card to the ./clockworkmod/backup directory (using an adapter since USB mass storage doesn't work). Put the sdcard back in your phone and use clockworkmod recovery to restore that nandroid to your phone. It's stock unrooted 2.3.3. Then use the one-click nvflash tool from the dev section to flash stock recovery back to your phone. Now you're back to factory condition.

Thanks for the suggestions. I already have a v21e nandroid backup. I just tried connecting the phone for nvflash, but that doesn't work, either. It doesn't show up in the LG Updater tool, either, when I plug it in. I think it's just plain broke. It'll charge, but won't do anything else.
I stayed up just about all night last night backing up my internal and external sd cards. I zipped the internal, placed the zip file on the external, then used an adapter to copy all the files on the external over. My biggest concern was the $50 in music I just bought that was residing on the internal sd and the keepass file I use for work.
Anyways, T-Mobile opens up in an hour. I'll head over after restoring the v21e nandroid backup I have. Hopefully they won't notice the ClockWorkMod recovery, heh.

Talked with T-Mobile. Apparently, I told them a few months ago that I rooted my phone and put cm7 on it. D'oh! They told me to contact LG, who could probably ship me out a new/refurbished device. If I did that, I'd be without a phone for multiple weeks. LG would see that I have ClockWorkMod recovery installed and could still reject my refurb request. I'd be out the cost of shipping and without my beloved phone for a few weeks.
I think I'll wait to see what Google has up their sleeves for their October 11th event. I might use this as an excuse to devour an Ice Cream Sandwich.
Thanks for all the replies and the help. If anything else comes to mind, let me know. I've loved this phone and would hate to part ways with it.

This happened to me 4 months ago. I tried everything with no luck. You'll have to get a replacement, I couldn't unroot it obviously but I installed a stock ROM and deleted everything custom. Only way they would have known it was rooted was if they powered it off and held down volume and power button. I've had my newphone since then goodluck

Thanks, this worked for me. I have been trying to figure out how to get it working for a few weeks now.
How common of a bug is it for the G2X? I Have not heard of it before.
----------------------------------------------
Probably a rare glich with CM7 stable, pulling out the battery did not make it go away, but toggling the usb did.

Make sure you don't have the usb charge only option check. If you do it will only charge and not connect the mass storage. Should be under settings, sdcard, first option.

[Q] Cannot Mount SD Card: Recovery or ROM?

I just updated several things on my Sensation. First, I updated from Energy Oct 18 to Energy Oct 22 ROM; second, I updated from Stock Kernel to Bricked v1.4; third, I updated from CWMR 4.0.1.4 to CWMR 5.0.2.0.
Everything is working fine, except for the fact that I can't figure out how to mount my SD Card when connected to my computer via USB right now. After rebooting after updating CWMR, I wanted to install Amaze camera v7.
I can't figure out why I can't mount the disk drive because I didn't change any settings. I have USB debugging enabled, and even in "connect to pc" when I set the default connection type to "disk drive" nothing happens. I also tried unplugging the USB cable and plugging it back in, but I still can't get the phone to bring up the prompt asking how I want to connect (and before you ask, I have it set to "ask me about USB connection type whenever I connect my phone to a PC). What do you guys think the problem is? Is it CWMR 5.0.2.0? If it is, I'll gladly change over to that EXT4 Recovery.

Remove you sd card and return it back to the phone.

It sounds like a problem with the SD card. As said above, try removing it and reinserting it.
Or if you have an SD carrier for it, try using that to read it in another reader and format it.

no option for disk drive

no option for mount as disk drive when connecting usb. only shows usb debugging. adb seeing device just fine. running prime 5 anthrax kernel shizilon v41. maybe reinstall htc sync drivers? any help would be appreciated. thanks

did u installed htc drivers ?

Have you check on Storage Setting ( Settings > Storage > SD card) either the SDCard already mounted (if mounted it will show Unmount SD card if not it will state mount SD card).
If it mounted and you have Custom Recovery try boot to Recovery and try mount and see if it working on Recovery. If not it maybe your cable/micro SD card/computer have problem.
If it not working check the ROM page either they have support this feature or not, or maybe you have to reflash the ROM again.

I think it was the shizilon v41 I flashed and maybe picked something wrong. Because a reinstalled the from and it back working. Kinda strange. I don't know what happened really. But I fixed it. Thanks

No diskdrive
I have the same problem.
I am on Android Revolution 6.6.3. and have been for quiet some time. Never had any problems. Until a few days ago all of a sudden:
1. The pop up option for charge or diskdrive dissappeared when plugging in the cable
2. The icon in the drop down menu has also dissappeared
The strange thing is:
- The phone however IS charging.
- I tried a different cable; same result
- I tried 3 different computers (winx64, winx32 and apple) same result
- I did the total disassemble (remove battery and sd card) and reassemble
- I can acces my SD card in my phone; it is working ok
- Settings are set for automatic connect as diskdrive
- I did not install any app that has to do with performance of SD card or stuff like that
Don't know what to do anymore: anobody got a clue???

For the first time something like that happened to me the other day... What I did was change ports, then I wiggled the USB connections, mine were not connecting as they should, once I did that it finally recognised it, but I think it's in the cable..... So after I reconnected and wiggled port connections it poped up. Tells me I need a new USB.again........this is my second USB I'm a short time. Sometimes they go bad. Perhaps this is your problem too? Fiddle with it and see if connection is the problem. Hope this helps in some way
Good luck
