USB Storage and USB Debugging will not mount to Windows 7 PC or Mac
*I'm posting this thread because I have exhausted every option discussed on the internet*
One day I decided to wipe more than usual using TWRP. I wiped Internal Storage and Android Secure. Ever since then, I have not been able to mount USB to my PC. No PC computer on planet earth will recognize my skyrocket. "Unkown Device" is all I get. Every USB cable, every USB port, every PC, every Mac I have tried. I've tried every driver set, I've tried formatting my PC and reinstalling fresh samsung drivers, I've tried Kies, I've tried formatting my SD storage, I've fixed permissions and wiped everything known to Android. Odin will not detect the phone without working windows drivers and neither will SuperOneClick. I'm out of cards. Game over. Every other function of the device works just fine, and I've gotten by using my 64GB external SD card as a means to transfer files between PC and phone. Come to think, this all started when I put that 64gb SD card in my phone and tried to format it and everything else in TWRP. External SD card works, but nothing will mount.
Before I explore the final possibility that the USB plug on my phone is physically damaged, I'd like to know if anyone out there has had any problems with USB mounting as a result of TWRP wiping and/or External SD Card installation/formatting causing things to go awry.
Any help would be greatly appreciated. I will donate to anyone helps me solve the issue, as I need to be able to sell this phone with a clear conscience.
Thanks!
What version of twrp are you using. I saw another post where it wouldn't mount internal with 2.4.0.0. Seems it might be an issue with that version.

It was using 2.2.3 at the time. I feel strongly that this is an issue with formatting the internal SD card via twrp while adding an external SD card to the phone. I believe the system partition responsible for mounting the phone is corrupted. Maybe a re-partition is the solution? If I could somehow restore the system partition files. I am an avid flasher but partitioning is beyond my scope. Maybe someone can point me to a guide about partitioning.

Hey man did you ever resolve this issue? I just erased a bunch of folders on my internal SD and it won't mount anymore. I'm using a Droid4 and, of course, the problem is consistent on both ROM and stock.
I guess for now I'll have to download from my dropbox account.
Cheers
I'm on the Note 2 (N7100) and have the same issue. I formatted internal storage in TWRP. Now USB is not detected on any pc. Any updates?

I keep getting errors when trying to partition my SD for use with Link2SD. Sometimes the computer won't create the partition, and then when it does, my phone won't mount the SD card in general. I'm getting kind of annoyed, hahah. Help?
Also, my computer's card reader is busted so I have to do it through USB mass storage mode. I'm running Bobzhome's ICS CM9 ROM which I flashed yesterday, and before that I had Harmonia 2.09.

Copy your data to pc.
Format your card and try partitioning through recovery.. simple!
It's been solved. My phone obviously hates CM9, so I went back to CM7 w/harmonia and everything is perfect again.
Sent from my LG-VM670 using xda app-developers app
ROM has nothing to do with your partition problem.
You can still use CM9 without any partition. If you have issues with USB mass storage on CM9.
Install latest USB drivers in pc.. it'il work!!
Yesterday I tried to partition my internal storage using minitool because I was getting a insufficient memory message from the google app store. Everything worked out fine and the partition had been created, I turned usb storage off and when I went to pull the usb cord from my nexus s I got a message saying that my internal sd card had been damaged and asked me to reformat. I dismissed the error message because I did not want to format right there but after that my phone can't detect my usb storage (16gb internal) and neither can I connect to my computer and access the files on my phone. I'm using paranoidandroid 3.00. Even when my Android debugging is on the phone still can't connect to my computer. And I've tried to unmount and mount using cwm a number of times but that isn't working either. I also tried to factory reset the phone but I still can't detect my usb storage. My phone basically says I have 0.98gb total space. I have no access to my internal storage at all. I can't flash any different roms or flash anything for that matter. My photo gallery is also saying that I have no external storage available. I need to fix this ASAP. What can I do to fix this problem?
Similar problem
I'm having a similar problem. Switched to a different phone and gave my wife NS4G, so I wiped everything, including the external storage via TWRP v2.4. No problem connecting to my PC, but on the phone in settings>storage, there was only 0.98 in Internal Storage and 2GB in USB Storage. No clue what could've caused that. Currently searching the web for answers, and will report back if I come across anything

I fixed the problem using Wugs Root Toolkit. I didn't want to just sit around and wait till a different fix just magically appeared. Basically just had to flash back to stock Jelly Bean 4.1.2 using the toolkit and unroot the device and then do a factory reset. The SD card got formatted after doing all that. You should try it out. :good:
Suddenly, from last week onwards, my internal storage seems to be having some problems.
It stopped working last week and is showing some very strange issues.
Under Settings > Storage, it only lists 1.45 GB of total space instead of the 8 GB it's supposed to.
Nothing gets mounted to /mnt/emmc
Using adb shell, nothing related to the internal storage appears when using the mount command.
Under CWM, I cannot mount /emmc
I've tried reflashing CWM and ROMs using NVFlash and still the same problem persists.
Every time I start Cyanogen Mod, the little "SD card is safe to remove" comes up
When I try to mount /mnt/emmc from Cyanogen Mod, it just brings up this message again.
Any opinions?
Thanks.
EDIT: It works now, I did a nandroid restore of the stock WIND firmware and that freed up /emmc... I don't know why this happened when all of my other efforts did nothing.
/emmc/ is your sdcard, not internal flash.
I've had CM7 corrupt my drive. Had to format and start over.

My Sandisk 8 GB class 10 microSD card become corrupted. Most files were OK but some jpg and a backup were unable to be read. When read/transfer/copy was attempted of the faulty files it locked up my computer. I tried various programs to fix and/or retrieve those files and tried a CHKDSK repair but those also locked up my computer so I saved whatever I could and did a full reformat, not the quick one, which completed without a problem and appears to work in the phone without any problem (yet?). You should do the same.
I lost my emmc early this year, think from flashing the wrong kernel. Couldn't find a way to recover. Will start doing more frequent external SD card backups.
Another odd thing I have is going into car mode even though I froze it with Titanium backup. Comes and goes with flashing different stuff. Recently flashed Mazout's on 2.3.4 and working good. But occasional BSOD that requires a battery pull and wipe Dalvik.

...Except no.
When my SD card was removed the problem persisted. Missing 5+ GB.
My SD card is 4GB... How could I be missing more than the capacity of my SD card?
/emmc/ is the internal SD card... the way this ROM manages internal storage. It is configurable in CyMod.
/emmc/ is my internal flash in this case, no doubts.
For anyone who is curious, be careful with mount commands as they will make recovery from this difficult and may be the cause of the problem.
I didn't know where to post this since it's not device specific.
The other day my GS3 displayed a message saying i can remove my SD card. I went to my file explorer app and I couldn't access my SD card. I took it out of my phone and put it in my pc, my computer made the noise to let you know you know it discovered a new device but then it notifies me that it failed to install drivers or software. I also tried it in my old GS Epic 4G running CM 10 and it gave me the same notification saying i can remove my SD card. So now I have an unmountable micro SD card and i would really like to recover the information off of it. I have run across a couple places that have said to format it then use recovery software but I don't know how to format a sd card that windows doesn't recognize.

Your card probably died, so unless you have specialized recovery or forensic software that can image the card, you're SOL. You could also try taking to a data recovery shop and see if they can do anything for you.
You may be able to recover your data with a freeware/shareware program but they're usually limited to recovering only certain filetypes.
If you've given up already and just need to format the HP USB Disk Storage Format Tool should be able to reformat the drive even if it doesn't appear in explorer.

Hello everyone.

And after googleing forever in a day I still can't find a way tobreformat it for my phone. It won't mount due to the wrong format. Please help!

What phone do you have?
Is it rooted? (you could reformat it thru recovery if it is)
Does the computer recognize it when you plug it in?

Please confirm that you had done an "eject" SD card from the MAC to unmount the SD card properly. This is the same as "Safe to Remove Hardware" for Windows. If not ejected (unmounted) properly, the next time you use it on another device, it may not be recognisable. If this is the case, simply insert the SD card back to the MAC and then eject it.
Otherwise, you can try re-initialise/re-formatting to FAT32 using software tools. Your phone recognises SD cards formatted in FAT32. If you format it with a MAC, it will not be in FAT32.
First, you can try formatting by using software for for SD cards, SDFormatter 4.0 - download from:
https://www.sdcard.org/downloads/formatter_4/
If that does not work, use a partition manager to re-partition and format to FAT32.

If you have a Mac, use the Disk Utility app (you can find it in the Applications/Utilities folder) for format the SD card.
After doing that you should be able to read and write the card on the phone, Mac or Windows without problems:
1. On your Mac, connect the card
2. Open Mac HD on your desktop
3. Open Applications
4. Open Utilities
5. Open Disk Utility
6. On the left you should see the hard drive listed. It should show the drive size with a second indented line beneath it that shows the volume of the drive.
7. Click "Erase" at the top of the screen.
8. Select MS DOS(FAT) File System for the volume format option.
9. Change the name of the drive if desired.
Click "Erase" at the bottom of the screen. You will get a warning and will need to click "Erase" again.
It doesn't show in disc utility. Cause its internal and won't mount
