Hi,
does any of you know if the device can work in USB Mass Storage mode, i.e. can it be seen as an external drive from Windows/OSX/Linux without additional software? I own a MacBook Pro and HTC support told me that they are going to release soon a piece of software that works under OSX, but it would be wonderful to have access to the device storage without additional software..
Question already asked and answered here:
http://forum.xda-developers.com/showthread.php?t=1543735
They dont use USB Mass Storage they use Media Transfer Protocol to deal with USB connection. This change was introduced in Honeycomb and has continued into Ice Cream Sandwich.
You can still transfer files to and from the devices its just a diffrent way of doing it.
Forum user Gogol posed these questions:
- Why Google is using MTP instead of USB file transfer on Honeycomb?”
He received the following response from a Google developer:
“MTP is a big improvement over USB mass storage — for devices with lots of internal memory, a manufacturer no longer needs to come up with some hard partition between the USB mass storage and internal storage. Instead, they are all in one partition, with MTP providing access to the directory of media files that would normally be available through USB mass storage. This means there is no longer a need for apps on SD card for such devices, because what used to be the ‘internal SD card’ is in the same partition as where applications are stored. The storage on your device can be used for either applications or media, depending on what you want to put on it. You aren’t stuck with how much space the manufacturer decided to leave for the two areas.
Oh also this means that the media storage doesn’t need to be unmounted from Android when it is being access through the PC.“

A main reason for using MTP rather than for example the USB mass-storage device class (MSC) is that the latter operates at the granularity of a mass storage device block (usually in practice, a FAT block), rather than at the logical file level. In other words, the USB mass storage class is designed to give a host computer undifferentiated access to bulk mass storage, such as compact flash, rather than to a file system, which might be safely shared with the target device (except for specific files which the host might be modifying/accessing). In practice, therefore, when a USB host computer has mounted an MSC partition, it assumes absolute control of the storage, which then may not be safely modified by the device without risk of data corruption until the host computer has severed the connection. Furthermore, because the host computer has full control over the connected storage device, there is a risk that the host computer may corrupt the file system, reformat it to a file system not supported by the USB device, or otherwise modify it in such a way that the USB device cannot completely understand it.
MTP and PTP specifically overcome this issue by making the unit of managed storage a local file rather than an entire (possibly very large) unit of mass storage at the block level. In this way, MTP works like a transactional file system - either the entire file is written/read or nothing. The storage media is not affected by failed transfers.

Very nice reply, thank you very much!
I've found Android File Transfer Google utility for OSX: http://www.android.com/filetransfer/
Actually, the One X still uses mass storage mode. Plug it in and you get the same old prompt for charge only, disk drive etc. and it still shows up as a removable disk.
Yes, vanilla android handsets like the GN use MTP mode, but HTCs don't. They have a separate partition still.
Hmm that's interesting if its true, it means HTC have implemented it independently of the OS. Could even be a selling point as I know quite a few people didn't really like the change from USB Mass Storage to MTP.
Thanks for the info!
I'm one of those who hates MTP because it is not as reliable as USB Mass Storage. MTP just doesn't want to play nice with my Win7 machine on my Nexus so I'm really looking forward to the One X and getting proper USB Mass Storage on it.
As much as i prefer MSC over MTP (mainly because you can open music and video files directly from your mass storage device, but if you use MTP, they will have to copy the entire file over to your computer before it will play), my office blocks MSC devices, but strange enough, MTP devices are not blocked.
Therefore i am actually trying to find out of i can use MTP mode in my One X, since MTP is embedded into ICS, there might be a chance. This will enable me to access my One X in office..
anyone has any idea?
I have a slightly similar problem here:
How do i tell the HTC ONE phone, that i want use the mass-storage-mode in USB, and not the f******g HTC/Nero bloatware crap?
Before the update to Android 4.1.1 it was working fine as mass-storage.

HTC has changed mass-storage-mode to MTP in their latest update. I didn't find any way to use as mass storage so I installed CM10.1 (A8 supports mass storage mode).

Agreed - I have the same problem with my OneX on 4.1.1. 4.0.4 was great, 4.1.1 is a backward step in several ways. My Galaxy Nexus (bought to play with Ubuntu Touch!) did the same [email protected] until it updated itself to 4.2.2, and now works correctly - to my mind - as a mass storage device. I think Google realised the error and quietly fixed it. I can't find a document that details all the changes in 4.2.2 so not sure.
I cant seem to find an option to use the Galaxy S4 as USB mass storage, only media device (MTP) or Camera (PTP) is available. Cannot find any USB options in the settings either.
How am I able to copy files from and to my SD card and/or phone HD?
I appreciate any helpful posts. Thank you!

with MTP my device doesnt show up in Mac, as well as my Sony TV or LG receiver. what to do?
Is there anyway to disable MTP and go back to mass storage? Also, is the SDCARD MTP as well?
Mass Storage is gone for good... and while it sounds bad, there's a good reason..
Using Mass Storage forces the storage partition (or external sdcard) to be unmounted by Android, so any data/apps/widgets on there are no longer available until you disconnect your device from your PC. Using MTP allows the data partition to remain mounted and available concurrently on both your device, and on your PC via USB.
1) No, you cannot get UMS back.
2) This belongs in Q&A.
3) For Macs, you will need this.

"there's a good reason" is somewhat subjective. To me the great benefit to the more general usb mass storage option is so you can connect the phone to any device as if it were a usb flash drive. No driver issues, no worries about camera or MTP mode, no Mac issues, no linux issues, no Windows issues ... it's just a usd flash drive and can be treated as such. I am ok with the side affect of auto-unmounting the sdcard from Android when I connect the phone to another device to use as noted USB drive.
Is there in fact any way this will ever come back?

There was an app someone made for the GS3 that did some filesystem trickery to expose the storage as UMS (needed root). I'm sure something like that will come around that works on the GS4 too.
I had the same issue until I installed Kies, no issues after that

How could anyone possibly know if it will come back, especially "in fact?" My guess is you would have to ask Samsung that question to get anything other than a guess or an opinion (which would be NO) but it's not "in fact" just "in an opinion."
I jumped from an S2 to the S4 and was also annoyed that USB mass storage wouldn't work either. Since I use Linux as my desktop, MTP is not an option "out-of-the-box". I therefor turned to an awesome app (that I heard about on this site!), Airdroid. Now I was able to quickly get an album/picture/book datastore onto a shiny new 32GB microSD! And yes, I know I could have put the microSD into a slot on my laptop, etc., but I shouldn't have to, just because I choose to use Linux!
I mean, its rather ironic not to be able to use Linux to connect to Linux (android), don't you think? If I'm completely wrong about this, please someone point me to the right path.
Thanks
There is a "hack" to allow the external to be read as UMS. Also, the internal sdcard is no longer yaffs2 its ext4 and only linux knows ext4. So if you were to use UMS, only a linux computer would "see" the sd card and nothing else.

elesbb,
That's awesome news! Thanks for the tip. I use opensuse (currently 12.3) with kde, will definitely make the necessary tweaks to get this going in dolphin.
Thanks again!
Ignore. Posted in wrong thread.
If you are rooted and busybox installed yes there are lot of apps on play store that can convert your externel SD Card to Mass storage.
Anybody have USB mass storage working? How about MTP? For the life of me can't find the answers. Tried the app on the play store 'SG USB MAS STORAGE ENABLER' but it only shows the sdcard as a CD drive and can't write to it.
Please help

Assuming that you are trying to connect to a computer,
USB Mass Storage does not work.
MTP Works, if you are not seeing your device after connecting to computer , then might need to install required drivers, or install samsung kies and that should install the drivers for you...
I have a SanDisk 64G XC micro SD card. Writes and reads no problem
Also USB (female) to micro OTB cable that allows me to use my 128 GB thumb drive, but not all of them.

Yes with my custom rom and kernel. I can connect any usb mass storage without a problem.
I think that OP asks about the option of connecting the device to PC in mass storage mode, i.e. just like normal pendrive, instead of the MTP/PTP protocols.
As far as i have found, it is possible only for the external storage, with help of dedicated app - there is a thread somewhere on xda, don't remember details, but hope it should be easy to find.
P.S. on Note 1 with Samsung stock ICS it was just a matter of running a startup script, don't know if it would work for Note 8

My device is rooted, I'm not as concerned with USB mass storage. I just want MTP to work. I tried uninstalling all drivers and installing KIES.
I tried uninstalling all USB devices and restarting windows 7 to install them back. I tried downloading the using the Note 8 tool kit to install them and NO success installing the MTP drivers. I tried a different computer and it works!
Any suggestions to getting it work on my computer???

Seems i missed a well. I'm afraid I can't help much with MTP problem, the only two suggestions that come to mind are: try on another PC to make sure it's not a device, secondly - on my Note MTP started to behave only after I installed the latest Samsung USB drivers (probably found somewhere on xda).
Since I have installed this update I can no longer access the storage on my one via usb to pc? Before the update I would just plug the usb in and windows would ask if I wanted to open this mass storage device and I would just click yes and then I was in. Now there is nothing. I tried explorer but cant gain access that way either. Is there something I need to install or change in the phones settings now? Also what the hell is MTP mode? Running stock 4.3 now and was stock 4.2.2 before this update. Do I need to update a driver on my pc now to accommodate 4.3? I am drawing a blank now as to what the deal is??? Can someone please point me in the right direction? And yes I have tried different usb cables
MTP mode is what google uses since 4.2. basically instead of the phone dividing up the available memory for apps / storage it now puts all available storage together for you to use what you need it for. before you would get phones with 8gb storage and 1gb would be dedicated to apps, 7gb for storage. when you installed too many apps you would run out of room on the 1gb and start trying to figure out how you could move apps to sd-card to get more storage, etc... now with MTP you don't have that issue. there is no preset to how much storage can be used for what.
you should not need any additional drivers other than what windows will automatically install when a new device is plugged in. also, my phone shows as a device now in explorer and not as a drive letter.
is it possible when you plugged your phone in via usb cable that you accidentally cancelled the new device install? perhaps you can go to your device manager with the phone plugged in and see if there are any devices with an yellow ! point and then try to reinstall drivers for that device.
I don't understand. MTP mode is the only way that the HTC One ever interacted with a PC. To my knowledge, Google removed USB Mass Storage as of JB 4.1
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.
