Is USB Mass storage possible? - OnePlus 3T Questions & Answers

I Is it possible to mount the internal storage as USB Mass Storage device on the PC. I like to sync the memory to PC from time to time. It is important that the internal storage is mounted as a separate drive and not a portable device.

Yes, just select the USB notification you get when you connect it and instead of charging you can choose to mount it as a drive.

When I select File Transfer option, it mounts as a portable device and not with a drive letter. As a portable drive I am able to access the files but cannot do automated backups using many backup software. Need to mount with a drive letter.

There's a reason for that. Read this:

Alternatively, you could enable USB debugging and use ADB commands or something to back up device data.

If your rooted try USB mass storage enabler (UMS enabler v1.6). I have not tried it myself

Our phones CAN NEVER do USB Mass Storage, NO MATTER WHAT.
http://www.howtogeek.com/192732/android-usb-connections-explained-mtp-ptp-and-usb-mass-storage/
We use EXT4 or F2FS, but not FAT(16) or FAT32 anymore.
OP or Mods, please close this thread as answered.

Lol! My linux box can read any file system. The issue is that internal storage is part of data now.
That said usb mass storage drivers work fine. There is a virtual cd drive with drivers. Im just wondering what linux /dev that is on the phone so I can wipe it and cram something else in there… make a rescue boot out of my phone!

If you want to boot a distro or windows or even a UBCD type ISO from the phone, that's what DriveDroid is for.

I tried it. It doesnt work at all on my device (OnePlus 3T) and the interface blows badly, although I hacked my own APK that works great. No interface, just tap an ISO from anywhere.

don't know how it works on a Mac, but there is no common usb mass storage currently, i think you mean that the internal sd and external sd
where be mounted as drives ...
you only can access the storages when mounted as MTP
hope this helps
Install "Android File Transfer" ( http://www.android.com/filetransfer/ ) and mount your 4X as MTP.
Thanks!

[Q] USB Storage/TWRP

I'm running the latest TWRP recovery on stock/unlocked/rooted (Sprint, if it matters). I know our devices don't have the USB Mass Storage option/functionality by default, and I certainly don't mind MTP for regular everyday usage. But obviously, when trying to mount USB storage in TWRP, it says this device doesn't have that capability. Any solution and/or workaround for that? With both of my previous devices, the E4GT and the Nexus S4G (which both used USB Mass Storage as opposed to MTP), the ability to mount to my PC from recovery was a lifesaver on more than one occasion. Any help would be appreciated.

what do you need to mount the sdcard for?
you can also mount it in adb or fastboot i believe if you need to. there are also programs that will let you mount it easy if you don't know how to mount it manually.

Anyway to enable USB mass storage for car use?

I really want to be able to plug in my nexus 6 on my car and be able to play audio. But no matter what I do nothing happens. Anyone have a solution?

Shot in the dark here, but try this:
Settings / Storage / click options in upper right / USB computer connection / disable Media Deivce (MTP)
Re-enable before connecting to a computer.
I'm curious if this works for you!
Mass storage isn't possible. We have to use MTP of PTP. The reason being that the sdcard is not separate. It is mounted in /data. Mass storage removes the /sdcard from use in the phone. But if that happened to /data, the phone could not operate correctly because it needs /data to be present. MTP and PTP share /data with the phone. That's why there are no mass storage options on /data/media devices unless they have a removable sdcard

It isn't so much that it is *mounted* in /data, but that it is PART OF /data. I.e., to share it as UMS, you would have to unmount the ENTIRE userdata partition to offer over UMS.

What app are you using to mount / view it?
What file system is it formatted to?

i assumed i could just plug it in and it would be recognized by any file explorer like es file explorer
i didn't receive any instructions or anything with it not sure what is needed to do to make it work
I have the same otg drive. All I did was: Plugged it in, went to Settings, Storage and erased usb storage. Checked in Solid Explorer and everything was good to go.

yeah, i don't get it this thing must be defective and very well could be since i got it from Amazon Warehouse.
I have even tried using Stickmount which supossedly mounts these drives for Nexus devices and it will not mount. i can't see it no matter what i try. just tried reformatting as well and nothing.

i want to say it is formatted in NTFS but i will try fat32 as well? i know ive tried two different formats as well. doesn't show up anywhere. from all the yotube videos i've watched minimally it is recognized with an icon when plugged in. i've never gotten that
EDIT - ok went and made certain to format to fat32. had to download a tool to do it in windows since my drive is 64gb. still will not recognize this drive. i rebooted, nothing. damn, no idea why.

I'm not sure if ntfs will work or not, I'm almost certain it will not, but I haven't tried it. I'm only suggesting fat32 because that's what mine is. When I plug it in, an icon shows in the status bar for just a split second.
Edit: Just seen your edit. I have no idea why either. I can't imagine anything being wrong with it, since it works fine on your computer? Will twrp recognize it? (If you have twrp installed)

in TWRP i assume it is not recognizing it either, but it does list USB-OTG (0MB)
there is nothing on the disc at all so twrp must just list usb-otg by default and it won't let me select it either

Just to make sure, for it to mount in twrp, you do need to have the USB plugged in before twrp boots. Twrp does list usb-otg by default. When it's working properly it will show the amount of free space in place of the 0MB.

ok yes, i definitely had it correct then. had it plugged in before going to twrp.
essentially, i bought a return at a low price off of Amazon warehouse. i don't understand how this thing could be fine in a pc or my chromebook, but it definitely will not show up on android. it must be defective. it would help if there were a light or something on the flash drive to show when its connected though.
i just tried it in my galaxy mega and it didn't show up either.
so i'll return it and try another one. i appreciate you trying to help.

Yeah I guess it might be defective. Maybe try another fat32 formatter? (Probably won't help any) I used 2Tware to format mine. Good luck anyways though!
I don't see any mention in this thread of EXFAT. I say this because I was having problems just yesterday (coincidentally) with TWRP 2.8 not recognising my OTG USB formatted as NTFS. Although TWRP showed the NTFS USB in the backup destination list, I couldn't select it. When I formatted as EXFAT, it worked in Windows, Lollipop & TWRP.
Method - Windows 10, Tools, Format - dropdown box select EXFAT.
(I believe that Stickmount provides an extension for reading & writing NTFS USB volumes, but that doesn't help for TWRP.)
Give it a go - nothing to lose...
I found I had to install Stickmount to mount my usbotg drives. I did install the supplemental files that allow ntfs and it works fine to mount/unmount external memory including an external 750Gb hard disk. [Edit] Didn't try with TWRP.

Problem with using a thumb drive as expanded memory

I've had a Chromecast with Google TV for about a week. I added a usb stick for added memory . I'm in developer mode and have unknown sources on. Using the X-plore file manager, I sideloaded games with obb files onto the drive with no problem. However, a few days later, the Chromecast got laggy (unrelated I hope) and I had to do a factory reset. Since then, X-plore will not show the USB drive if I'm using the USB stick as device storage. I'm pretty sure that was the way I had the stick formatted before. When the stick is formatted for external storage, I can't transfer data to it. When it's formatted as device storage, it's not recognized on the file manager. Also, the file manager won't allow for an obb folder. I get a msg saying it's not allowed.
How did I screw this up? Please help :fingers-crossed:
Thanks from a confused noob
is it fat32?

Yup.
I think I figured it out last night. After I factory rebooted it, I didn't change some of the storage permissions on the apps .
Can't seem to get passed read only error with x-plore. Do I need to format to fat32 and how. PC is old and only gives me option for exfat and ntsf. Thanks in advance
