Previously, in order to prevent corruption to the external SD, one was highly advised to eject the USB mounted SD drive from the PC before pulling the plug. However, with the new MTP configuration, is still advised to eject or un-mount the storage? I would think that once file transfer is complete, technically it should be OK to simply disconnect the cable from the PC. Any thoughts?

It has technically been okay to pull out the cable from the PC, as long as it is not transferring information then no data will be really lost. However, MTP is more like a USB. It is always better to do it. It takes maybe 5 seconds more, but it gives you a piece of mind, so why not?

So, i had a rooted mytouch with a custom rom.. Pretty familiar with the android OS. LOVING my nexus, except for this stupid problem. (its no my SD card btw, works fine in my girlfriends droid)
Anyways, i cannot mount my SD card when i am plugged in my computer... I am out of ideas. Anybody have the same problem?
what happens when you try to mount it? please provide more info!
i have the same problem, the only time where it'll let me mount my SD Card is when i put it in developers mode.
If I recall correctly from the user guide, you have to pull down the notification area on the phone and tell it to connect via USB. After this you should be able to mount the SD card. Again, if I recall right.
I wish i can tell you more but.. thats it.
You connect the phone via USB. Pull down the notification menu and there is NOTHING there. I cant try to mount it, i don't even have the option to mount it.
Should i record a video of it?
It should at least recognize that it is connected through USB, it does not. I put my SD card in another phone, hooked it up via usb, transfered all my stuff, then put the SD card back into my phone and EVERYTHING works, it reads it fine. I just cant mount my card from my notification menu. Its empty.
*edit* I have also installed the latest USB drivers from the SDK update, still cannot mount my SD card... I am starting to think the problem is deeper for some reason.
I think I'm having the same issue as the op. I downloaded the latest driver and the computer recognize my Nexus One, but oddly the drive the SD card is suppose to show up in is saying I have no SD card. Whenever I try to open up the F Drive(Nexus One SD card) it tells me to no media. Not sure if I'm explaining good enough.

are you connecting it directly into the computer? if not try doing so. If you are connecting it to the computer try a different USB port.
I've just got a 32GB Sandisk Class4 MicroSD and my transfer speeds are horrible when mounted over USB.
Also after some time, the transfers may fail, and the mount is no longer reachable. I.e. you can no longer browse it through My Computer.
When this happens, the phones interface grinds to a halt, and I need to restart it. Key strokes will take seconds to come up, etc.
I've tried reformatting the SD card, reinstalling Kies to get the latest USB driver, but the speeds still the same.
I found if I manually did "safely remove hardware" for the Android internal SD mount, the speed is a bit faster.
Any ideas?
Try adding the phone as a USB mass storage with USB Debug On, also use only the supplied Samsung cable and finally did you format the card in the phone before you started using it?

I couldn't find that, but ran H2TestW, which managed to write all the files fine but had read errors.
Not sure if that is because I have it going through the phone, maybe I should try an SD card adapter to the PC?
First of all, is there a way to connect via USB 3.0 to a Mac? There is Android File Transfer which will support MTP but it's USB2.0 only.
Secondly, when I connect it with USB 3.0 onto Windows the connection drops every 2 seconds. I've heard that this is due to me having an SD card and you need to unmount it first? But if you can't use a card USB 3.0 is rather pointless because the internal storage I would assume is FAT32 and won't take files larger than 4GB anyway.
Hey everyone,
I was wondering if anyone can help me. I'm trying to put files like emulator files on my usb drive that has been converted internal storage (usb). My computer won't read the usb after it is formatted to be an internal storage.
I have the files on a sdcard but wondering how I can transfer all that to be on the usb drive.
Please let me know thanks!
As far as I know once you format any external storage as internal then that drive is going to be encrypted. This is the reason why your PC won't read it when you insert it back to its own USB ports. You can read it via NSTV if you connect it to your computer via USB cable as long as you enable USB debugging. To recover the USB for general use you have to erase it from NSTV/storage and then eject and then it might work again on your PC. I said it might because sometimes you would have to do a low lever format to completely remove the encryption. Good luck.
Ok, So I used to use a moto G. On that the OTG used to work like the usb on my laptop plug in a Fat32 drive and it'll easily read and write to it no problem.
But I switched to a Moto X Style with marshmallow and when I first connected a Fat32 formatted pendrive it asked me to reformat it to make it work on the phone. Which I did, after that in ES File explorer theres another folder within the root of the USB drive to which I can write but those files cant be seen on my computer or any other computer for that matter, just the phone. Cant even see that folder anywhere else.
??
What the hell is up with the OTG? How can I access my drives without having to format them and retain write capability as well as the ability to read my written files on windows and what not? Its a new phone so I do not want to root it.
Thanks for the help.
You may have messed up somewhere by formatting it into internal storage or something.
Backup all files from the pen and format it in you pc to either fat32 or exfat depending on drive capacity and needs, eject it and plug it into the phone. It should work fine, also always eject drive before disconnecting it from the phone and if your pc says the drive has issues and wants to fix them ignore it.

Well it formatted it as portable storage. I tried reformatting to Fat32 from my computer but the same thing happened it wouldnt open unless I formatted it for the phone. What gives? And yeah I know microsofts error thingy does more harm than good.
UPDATE:
Its working now, reformatted using my windows machine. Was using a mac before but for some reason the phone just doesnt like the way the mac reformats it. However my SanDisk ultra dual usb still wont work. Time to buy a new otg pendrive.
