[Q] Can't mount USB Storage on my Windows 7 PC

The problem is more about my PC than the Desire as it works as normal on other PCs but not on mine.
When I plug in my Desire it asks me to mount the USB Storage and when I accept the Device shows as "Removable Disk (F" opening it results in "Please insert a Disk into...".
Under Device Manager it shows as "Portable Device" and under "Disk drives".
I uninstalled every device with Android in it and then rebooted my PC and reconnected my phone but still no luck, I also tried installing the newer HTC USB drivers (didn't work) and then uninstalling them (didn't help). It must be because of some driver but I have no clue how to fix it.
Does someone know?
I have the SDK, the unrevoked HBOOT Drivers, the HTC USB Drivers (from the Sync app) and Windows told me all the USB Mass storage drivers got installed and should be working.
//Edit:
When I mount the USB storage, got to the drive in the Device Manager and select populate in the properties and then go to the Disk Management I see the Disk but it's labled as RAW. When I then re-format it, it actually works until I unmount it and then re-mount which presents me again with my previous problem.

If you just want mount the USB storage, you no need to install other software or SDK.
I think that is your pc's problem, try check your pc.

Are you using the original micro usb cable from HTC or a dodgy cable you bought really cheap? There are a lot of bad cables around.
It could also be that your SD card is about to die.

@ First line he say it works as normal on other PCs but not on mine
so maybe not cable problem

To mount the Desire's SD Card in storage mode you don't need any drivers than the ones came with the OS - tested on XP, Vista, Seven and Ubuntu - it's like sticking in an USB pendrive / external HDD.
Did you tried a different USB port?
Also try set USB debugging mode on (Settings\Application\Developement)

Original cable; SD card mounts fine when taken out and used with an external reader; tried other ports; no problems on other PCs; Debugging on or off doesn't help
I know it's my PC but I don't know why and how to fix it. I also know that it installs everything automatically and I don't need to install any other drivers but one that is installed, seems to break everything.

What about USB extensions? Do you use this @ your PC? How many other USB Devices are connected to your PC? Maybe your phone doesnt get enough voltage via USB. I know both problems from my personal experience.
So first, if you use extension cable, remove it and connect your micro USB cable directly to the board.
Second, try to remove 1 or 2 other devices plugged in via USB (scanner, printer, cardreader[!], webcam, for testing purposes even mouse or keyboard)
Maybe this fixes your issues.

No extension cable
I doubt the power being the problem as my Galaxy S II had no issue and as stated above I could kind of get it to work but not as it should have worked.

You DOUBT the power beeing the problem, or you tried and can EXCLUDE this possibility?

Considering what I've already tried (as detailed in previous posts) I think I can exclude the power being the issue.
I've also synced and charged an SGS2, an iPod touch and an iPad from the same plug without any issues.

I tried so many things in the device manager... nothing worked...
Once I could get it to mount correctly but only until I unmounted once, after that it would go right back to my problem.
I really have no clue on how I could get this to work again

I give up... I even restored Windows 7 to a previous state and it did not help.

Made some progress and can reproducably access the SD card but sadly only until I unmount and afterwards I have to run through the procedure again to get access:
I had an USB Harddrive formatted as NTFS through NTFS-3G on my mac and my Windows 7 PC also wanted to format it when I plugged it in and it showed up as RAW in Computer Management. I then remembered chkdsk did a chkdsk I: /f and it worked again even after a clean eject and remount.
I then tried this on my Desire as the symptoms seemed the same or at least related. Here is my console output:
C:\Windows\system32>chkdsk H: /F
The type of the file system is FAT32.
Chkdsk cannot run because the volume is in use by another
process. Chkdsk may run if this volume is dismounted first.
ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID.
Would you like to force a dismount on this volume? (Y/N) y
Volume dismounted. All opened handles to this volume are now invalid.

After this, Windows showed that it mounted DESIRE correctly and asked me what I'd like to do with it and I could browse the card and do whatever I wanted.
But this isn't ideal behaviour and I'd love it if my Desire would just show up as normal and work normally when I connect it to my PC. Does this give a clue on where the problem might be?

Hello
I had a simular problem
I could mount the sd on my desktop but not on my laptop.
So apparently it was not a cable problem...
But finnally I use the original cable and now it mounts on both computer.
Hope this helps

[Q] File transfer using usb cable

Sorry if this has already been discussed, but I didn't found any answers regarding my issue.
So how can I transfer files from my pc using the pad's USB cable?
On my Sony phone with ics, it was enough to enable usb debugging mode and the pc sees it as a flash drive, using usb mass storage.
But here it seems there's no mass storage mode, only mtp and ptp which I don't like.
So what options do I have to actually see my 64 gb card when I connect the pad to the pc? Is it possible?
Cause even with debugging mode enabled it doesn't change anything, still have to use windows explorer and it's working very hard. Any help would be much appreciated.

Not sure I fully understand what's wrong with mtp option but I can fully see my 64GB card when connected to my pc via usb cable. I have successfully copied files to and from the SD this way with no issue. Explain what issue you may be seeing.

Can not see why you have any problems when my G Pad is connected I can see it as a device in My Computer " Not Devices " and when I open it up I see two drives. Internal and external SD card
Make sure you have loaded the LG USB Drivers
Plus it should come up with a list of what you want to do when connected click Open and view files

Thank you for the replies, guys.
Not sure if i made myself clear. Yes, my pc can also see my g pad device in My Computer, but it is not listed as a removable flash drive or an external hdd, thus i cannot see sd card properties, format options and so on. I usually use total commander for transferring files, because windows explorer is way too slow in doing this.
For example, if i want to download a movie or some songs directly to my tablet, how can i do that? With my sony phone is easy, my pc sees it as a removable flash drive, thus is easy to save files directly to it.
But with the g pad that option is gone, or at least i cannot find it. I must first download the files to my pc and only after that transfer them to my pad using windows explorer, which is really working hard. Basically, i have to wait one hour for downloading something, than another hour to transfer the files to my tablet, instead of downloading directly to the tablet.
And all this i believe is the effect of usb mass storage mode missing.
So in the end, is there an option to satisfy my needs?

In settings, go to "system", choose "PC connection", choose "media sync(MTP)".

MTP option does exactly what i was saying earlier, it only gives me the option to use windows explorer to transfer files.
It does not satisfy my needs, as i cannot save files directly to the tablet's SD card when downloading something, for example.
Can you people see the tablet's SD card as another DISK drive in your pc? With formatting options, sd card properties and stuff that you can do with a flash drive or an external hdd? This is my question, but i believe this is not possible.

I have no problems it must be your USB drivers as mine sees it as a Device
I open mine up from my computer then open the SD card and transfer all my Movies and Pictures direct to the SD card I can open up files on Device or Card

Hi again, i've attached some print screens with the issue i'm trying to explain. The main thing that bothers me is the clearly slower speed for transferring files using windows explorer. With total commander it goes almost double the speed rate. Plus, why should i download a file to my pc instead of downloading it directly to g pad's sd card? Waste of time in my opinion.
But recently i did read somewhere that jelly bean does NOT support usb mass storage, so i guess that answers my question.

LG G3 D855 Broken Screen

I dropped my G3 and now I can't use the touchscreen. I want to transfer some files on my PC, but the USB debugging isn't enabled and there isn't a recovery, so I can't enable it from my PC. Any suggestions?

If you have a memory card, otg adapter, and a USB mouse you could use the mouse to navigate to a file manager and move the files to your memory card.

Transferring Files from PC to Phone

Anyone else having the issue where they can't transfer files from their Win 10 PC to the phone? I have it set to File Transfer mode when I plug it in via USB into the computer. When I pull it up in File Explorer, it says "Phone". Double clicking it shows my MicroSD card and the internal storage. Then when I try to click and drag or Ctrl-C Ctrl-V a file into either spots, nothing happens. I did try enabling USB Debugging mode, but that's not required for a simple file transfer. This is honestly kinda ridiculous. Also, when I'd take my MicroSD and move files from windows to it by connecting it to a USB adapter, the files transfer onto the card, but as soon as I plug it into the phone, all those files disappear in the file explorer and are replaced with a file or folder called System Volume Information. Anyone else having issues??

Nope have copied files from what's app for printing and copied my music to phone storage and external memory card as well,

I had no issues using the steps you used. I just grabbed my USB-c to USB cable for charging my old oneplus, and it worked.

I used Bluetooth to transfer a few files from my PC to my phone. It worked great

Bluetooth works, plugging in phone (sd card formatted as internal storage), and Teamviewer works. I think I might use Teamviewer as it's similar to a ftp client program, makes it real easy.
What did you format the sd card as? Internal or external storage?

Same here.

For normal files and documents i just use Google Drive, i don't have huge important files i need to have when i am out and about so i am unable to test this as i haven't had a need to plug my phone into a pc for 2-3 years.
Bluetooth would work or an SD Card reader, as there are so many ways to get files between a pc and a phone without a cable its partly why ive not even bother to check the does my phone work with my pc step. Back in the days when you got Software and Drivers for your phone are a thing of the past.

I using wi-fi to transfer files you can easily find an app for that

Which app are you using?

Heya, chiming in here to suggest Airdroid...look it up, useful and needs no plugging in, just used your WiFi networks to do the transfer, very useful tool (I,d like to thank YouTubes Mr Mobile ((Michael Fisher)) for that)

No problem here also...I just use my GoPro5 Type-C Cable with my Razer, and Copy and Paste in Windows Explorer....easy. I recommend you try another cable

Using an anker "normal" usb to usb c cable works fine to transfer files. But I can only transfer files to the SD card, internal storage doesn't appear.
For transfer via WiFi I use es file explorer, it connects fine to windows shares even with needed auth

OTG misfunctioning

I have a USB c flash drive. Whenever I copy a file from internal memory to the flash drive, it seems to be successful, but when I expell it and re connect it the file is not readable. This happens with solid explorer, while the internal file app seems not to have this problem. Upon first connection I have the given the access to the flash drive as required. Did anyone have my same problem and find a solution?
