[Q] USB Mounting

For some reason, my phone will not give me the option to mount my SD card as a disk drive all of a sudden...
I'm using CM 7.0.2.1 with Tiamat 3.3.8 as my kernel. Anyone know how I might be able to fix it?? I'm trying to put KingdomRom on it but can't because I can't mount .
I've also tried a full wipe and reinstalling the ROM with a different kernel...and I'm still not getting anything. I've tried multiple USB cords as well.

I would try unmounting your SD card in Settings then reboot the phone.

Didn't work . I thought originally it might have something to do with the kernel, but I've changed to a different one and it still isn't working.

When you connect your phone to the computer, does the charging light come on? What happens when you tap the notification that says your phone is connected to the computer? Do you get the screen with the option to mount and it doesn't, or do you not get the notification at all?
Have you tried using something like Widgetsoid to toggle usb mount? I had a similar problem on Sense and using a widget to toggle mounting the phone as disk drive was the only way I could get it to work.

Also, what recovery are you using?
Sent from my sometimes infected,MIUI,Kings UNleashed Ultra Supersonic EVO...

Using ClockworkMod. I just stupidly reformatted my SD card after reflashing my ROM, so now once I am able to redownload GApps, I'm gonna download one of the widgets (might try AutoSync, too) and see if I can make progress in the morning.
Update: Got Market back on, downloaded Widgetsoid, enabled USB Mount...and still nothing. I've tried on 2 computers now with different USB cables and nothing.

Is it saying that your phone is connected to your PC at all? It could be your USB port, or your cable is going bad. Try plugging it in to the computer and jiggling the plug near the phone's usb port and see if it tries to connect. If it does, you may have to move it around until you get it to connect and then be very careful not to move anything while transferring files. Also if you have wifi you can transfer files by using an app from the market called wifi file explorer. They have a free and a paid version. Does you phone connect when you mount it to the computer in recovery mode? Does the charging light come on when you plug it in to your computer? Really more info is needed to diagnose your problem. There are also widgets in the market that will allow you to mount the phones storage without unmounting the card from the phone. Maybe this will work for you. Maybe the card is going bad? Who knows, but hopefully some of my suggestions help. If all else fails, you could always do it the old fashioned way and power the phone off, take the card out and plug it directly into your computer via the adapter if needed.

Yes, I do receive a charge light when I plug it into the computers USB. Android just does not provide the option to mount as a disk drive.
I like the Wifi File Explorer Idea. It sounds like a good alternative. Thanks so much to everyone for their suggestions!

[Q] Mount SD No Longer Works?

It was working fine yesterday, but today in MIUI (same as yesterday), I can tell the phone to mount the SD card but it doesn't show up on my computer. So the phone says it's mounted, but it apparently isn't.
To make sure it wasn't a problem with the ROM, I rebooted into to CWM and mounted there, same thing. CWM says it's mounted but it doesn't show up on my computer.
I can view and edit the files on the SD card through ES File Explorer, but the SD card no longer appears on my computer?
It's not the USB port, I plugged in a flash drive and it worked. And I'm using the stock HTC Cable.
This is on my Inspire.
I'm inclined to say it's the wire, but nothing happened to the wire between today and yesterday. It was just sitting on the floor, and it still charges the device.
I did reboot my computer and phone...still no luck.
Does USB debugging have anything to do with it? I've been rooted for months and I never disabled and it didn't cause problems :/

Out of the two inspires in my household, one of my cables stopped working only a month after I bought it. It still works for charging but does not work for data. Have you tried a different cable just to be sure.

It might not be the phone nor the Rom since you've done some basic trouble shooting. It could possibly be your PC. Have you tried it on another computer? Possible driver problems or drive letter conflict might cause it not to display in Computer.
You can check whether Windows has detected your device by going to Start > Devices and Printers, it will pop up there if it is detected. Otherwise you can also check Disk Management. To do this just right-click on Computer > Manage > Disk Management. If you see the removable disk and sure that it is your SD card then it might be a driver letter conflict which you can easily fix by right-clicking on the removable disk and clicking "Change Driver Letter and Paths" and changing it to an unused driver letter. I've had similar issues with USB drives in the past. Hope this helps!
Cheers

Follow up on USB Host
I too am using an HTC One X running 4.1.1
I've got an OTG cable and have tried connecting a thumb drive and card reader. Both work. The drives are visible and accessible on the phone. That's USB storage which isn't the same as USB Host, but it shows that the port is active.
I can plug in the dongle for a wifi mouse, it too is recognised and I'm able to use the mouse to navigate around on the phone. This, as far as I understand, is actually USB Host in action.
The problem arises when I try to connect a DSLR and use a camera controller app like Helicon Remote or DSLR Dashboard. The app doesn't recognise that the camera is connected.
What's the difference between the wifi mouse and the camera?
Thoughts appreciated. Thanks.

In fact, there is a problem that any USB storage device on the phone creates the following folder structure:
/ storage / usb / Android / data / com.htc.album / .thumbnails /
Then create multiple copies, can be found in the internal memory, same-path, including folders that contain thumbnails, but empty.
So because of these being used constantly sticks, so when the capture traces of the settings, then any writes to the phone to choose from, but it can not happen, but the capture button will be disabled, but only while again not I step into the menu.
The above mentioned directories erased because the phone reboot always create them again.
If the phone was not rebooted since I've used it and the flash drive has been physically removed it, then if I connect again, it appears no file until you restart the phone.

[Q] “USB Storage damaged. It may need reformatting” error message on OTG

Hello everybody,
I have the following problem appearing recently:
Whenever I connect a USB stick through OTG cable to my Galaxy Note II I always receive the message “USB Storage damaged. It may need reformatting” in the status bar, no matter which stick or other mass storage device I'm using. On my PC, the files are perfectly visible.
I didn't tamper nor change anything on my phone, it's been running the original Samsung ROM, rooted but otherwise unchanged, for the last six months.
Could any of you help? I explored several threads with reference to the same error message on other Android devices here and in other Android forums but none of them matched this problem.
Thanks in advance!

Hi,
Have you tried smaller sized USB sticks?
Because my 1 terabyte SeaGate hard drive works but turns off because it needs more power.

Yes, I tried with a 1GB and a 4GB sticks that worked quite well on OTG last week.
Both these sticks still work well on my PC.

It wasn't.

(BTW, thank you for taking the trouble to help me!)

No problem helping :highfive:
Well, I had no problems with USB OTG yet (except the 1 tb)
I suggest you factory reset or change the OTG cable.

I tried the cable as well...
Factory reset is a bit radical.
Does anyone else have an idea?

solution
Hi I had the same problem. I found the solution myself. Android doesn't support NTFS format actually. Format the USB with fat32. There u go. :good:

Use NTFS mounter app.....it needs root....

The problem is caused by kernel and USB drivers. Depends what kind of ROM is installed on your phone.
Some of the ROMs dont recognize big variety of card readers. Now I am using some cheap china phone,
so i had hard time to find the correct SD card reader.
Before, I was using Paranoid Android on Nexus 7, I didnt have problem with mounting any size of card, any kind of card reader.
Try different card readers , play around, you will fing the way.
:good:

I have the same problem but both the cable and drives work fine on my Verizon G3 but not on my T-Mobile G3 running 6.0.1 mm based Turbo ROM.

My S5 suddenly refused my Usb Otg drive for no reason. It was working fine. It also corrupts the drive so BE VERT CAREFUL before connecting any mass storage to Android. Why is that?

OTG support foe Flash Drive after updated to Android 10 and One UI 2 on Note 10+

After updated my Note10+ (Exynos) to Android 10 and One UI 2.0, I found one serious problem:
Problem: When I inserted Samsung USB-C to USB-A adapter to the phone, then attach a USB drive (which work fine on the same phone when running Android 9, and the device was checked to make sure its functioning), Note10+ fail to auto-mount the USB drive. There are no response, and Samsung My Files app do not recognize the USB drive
Workaround: To make it work, I have to install Sandisk Memory Zone app from Google Play. after that, when I inserted the USB drive, Sandisk app detect the drive and I can transfer file using Sandisk app as usual. However, Samsung stock My Files app still do not show the USB drive as it should be
Another work around is to mount the USB drive with Paragon NTFS eFAT/NTFS for Android, then browse or transfer file with Total COmmander file manager. Still, Samsung My Files app do not show the mounted USB drive at all
I think there must be a bug with Samsung firmware or My Files aapp that need to be fixed. I have reported this to Samsung Support staff over the live chat
Any friend experience the same problem? Or it is just me?

I have always had issues with the native file managers from samsung, exactly Those you are here posting, I use xplore, I first used it from my Symbian days, when migrated to android samsung devices, it was natural for me to use xplore, zero problems, and it is really straight forward to use and much more flexible

After testing many times, more workaround solution is here. It is repeatable
1. If I restart Note10+ without USB drive attached, and then insert USB drive via Samsung USB-C to USB-A adapter (it came with Note 9), the USB drive will not be detected
2. To get USB drive detected and work, I have to insert the USB drive, then reboot. After reboot completed, Note10+ will detect the USB drive, and the drive will show up in Samsung stock My Files app. Manage files can be done. When I inserted and reinsert the USB drive, it will still work fine.
2. But if I start Sandisk Memory Zone app, it will detect USB drive, and file management can be done via Sandisk app built it file manager. But in this case, Samsung stock My files app will stop detecting the USB drive until reboot with USB drive inserted
Before upgraded to Android 10, Note10+ running Android 9 will hot swap and always detect the USB drive. Also, Samsung stock My files app and Sandisk Memory Zone will work without problem simultaneously
I think this is a bug that need to be fixed by either Samsung or Google

Native USB support seems to be working fine on my N975U from T-Mobile(USA).
Both using a native type-c flash drive and also using the adapter that came with the phone.
