I am trying to help someone debug some software on one of these tablets and i am running into an issue with the file system.
This program has a PC component along with an App on the device.
The PC program uses adb to push the db and image files to the device.
On my phone when I plug it in to the usb port I just tell it to Charge only and everything works peach keen.
But I am finding with a lot of tablets there is no option to just let the device be pluged in and it will auto mount the "sdcard" file space for copying files over.
From the screen shots I have gotten it seems like the system is making a Sym Link to the drive space on the tablet.
As in it isn't showing up as a removable drive like my phone does when you mount the sdcard, but it looks to be under computer\GT-p7500\Tablet\
and the typical trick of clicking on the address bar to get an absolute address return no drive letter.
It is a stock unrooted device, and what I am looking for is if there is a way to keep it from mounting the "sdcard" or how it is mounting it with in the windows file system.
It has been slow going as the guy I am trying to help is in the Netherlands and I am in the states so there is a bit of lag on correspondence
Thanks for any help you can pass my way

Moving to Q&A
I don't know what i'm doing wrong, but I can't seem to transfer files to my device for any extended period. I don't know what does it, but at some point, the connection always fails. Windows says the device isn't responding and closes the explorer window or stops copying files, but the device itself says everything is fine.
What am I doing wrong?
You may just need to download some Windows drivers:

All you really need is the small USB driver (8 MB). I think that the Global button would be the easiest download. There is also the PC Suite, that includes the USB driver, but not sure you want all of the extra stuff included in that.

It's installed, but the problem is still presenting.
Well, what are some of the details? What type of files are you transferring? What folder are you copying them into?
Try creating a new folder on your Prime and copying into that folder to see if it makes any difference. Some users have been experiencing issues with the Music and Movie folders. If that is the case for you, try copying into the different folder. If that works, you'll probably just want to delete the old (bad) folder and rename the new one to the old name. Make sure you copy any items out of the old folder before deleting it.

No, that doesn't help either. Any kind of file. ebooks, movies, sideloaded apps, it seems to be completely random, just sometime, out of nowhere, "File cannot be copied, device is not responding, skip or quit?" and sometimes if it's multiple files and I skip the one that DIDN'T work, it keeps going like nothing's wrong.
I did neglect to ask you what version of Windows you are using. But, I'm really not sure there is anything that can be done anyway. I assume you have MTP checked on your Prime settings or you would not even be able to see the Prime on your Windows machine. Anyway, I'm at a loss at this point.
Do you want a workaround that will work with a wi-fi connection?
1) Download Airdroid from the Market to your Prime -- it's free.
2) Run Airdroid on your Prime.
3) You will be given an http address like http://192.168.1.1:8888 and a password.
4) Enter the http address into your internet browser on your PC and enter the password when asked.
5) Click on the Files icon on the web page that shows up on your PC.
6) You will see your Prime's file structure on the left side of the page -- click on the folder that you want to move the files to.
7) Then click on the Import button ... upper right.
8) An new window will appear for importing. Click the Select Files button and any file you select in the browse window will appear in the list and automatically be sent to your Prime.
This is just one of the many things that Airdroid can do.
I have done this many times and find it quite easy and reasonably fast -- not as fast as your wired connection would have been, but at least you can do this.
Yes Your only options at this point is a slow wifi transfer or buy an sdcard to copy files to then transfer in the device it self. This seems very acceptable to some people.
MTP is garbage and has never worked well for me either.
I think this is an android hc/ics problem though.
Maybe once/if we start getting costum roms we will see a usb mass storage option. We will just have to wait for the unlock tool.
Might these filenames contain special characters?
Also, the MTP driver seems to have a hiccup sometimes, check your device manager (Win+R "dvcmgmt.msc"). If there's a little warning at the MTP device, mark it and hit delete or open it and hit Driver Details/Update driver.
Sometimes the queueing of files is also out of sync with the actual transfer to the device. I've had it happen that I wanted to copy a bunch of files, and the device must have reported "tranfer complete" on the first file while it was actually still busy, resulting in a "device busy" error on the next file. When I copied the next file by itself, it worked fine.
MTP is slower than regular USB mass storage because it is designed for hot (un-)plugging, so no delayed writes.
Conect your TFP to your PC once with USB debugging checked and once without being checked. See if drivers DL or update.... Check devise manager to see if drivers are installed if yes reboot computer... Some PCs will not recognize devices without rebooting. Next try a different USB hub and repeat something will work

I've noticed that when you change the file name sometimes it works. On my galaxy nexus I have the same problem. But I would transfer files it wouldn't work and then I change the file name and it would work
Lots of good suggestions here that you can try...
However, one more possible work-around that worked for my Ubuntu machine (where MTP is not working, either), in case nothing else works:
I switched to PTP (camera) on my TFP. I could copy just fine. However, this means two steps (a copy then move), because with PTP, I can only copy to the DCIM or Pictures folder.
Well PTP is faster. But it still tells me my camera wont play the file...

Thanks for that idea. I was going to try that when I got some time but wasn't sure how it would handle it. I can handle just having to movie it to a diff folder once I get it on the prime.
Like the other poster said, can't wait to get a custom rom on this thing.
I ran into this annoying problem yesterday too. At first I thought it was an issue with the drivers on my Windows 7 box, so I went over to my Debian box and installed MTPFS, but no dice. The exact same thing happens - the computer is able to initialize the connection at first, and if you're quick enough you might even be able to copy/delete/move something, but after maybe 30 seconds or so the connection fails - transfers stop, renaming hangs etc. This was the exact same thing that happened on Windows 7 and so I must conclude it must be the TFP itself having issues with MTP. Running ICS IML74K.
MTP works but the date of all files and folders is wrong

MTP works for me (Ubuntu 11.10). But I have found out, that once the internal storage is mounted in Ubuntu, the date of all files and folders are set to 1970-01-01.
Actually before, short after I had activated the Prime, I realised that the date was also wrong. I'm not sure now, but probably the same 1970-01-01. Then I adjusted the date and the upgrade to ICS went flawlessly.
Now I start thinking that this wrong date could be one of the reasons for many problems in TF Prime.
Does anybody have the same problem and know a solution?
I read in another forum when i was trying to get mtp to work on my nexus s that if you install media player 10 it can solve the issue of mtp not working in windows xp. Not sure if this applies to windows 7 though as i thought windows 7 was supposed to be able to use mtp out of the box.

On my Galaxy S2 MTP works like a charm, so it's not MTP in general. Maybe it's a bad USB cable, connector probs or Windows acts up.
It's May, and MTP is still garbage.
I've been trying to find a way to mount my DNA to my linux work machine, but for the life of me I can't figure it out. All searches of the net yield nothing successfully. I assume it's because the phone keeps connecting as PTP, when I really need to have it in MTP (I miss mass usb storage;( ). Has anyone had luck connecting theirs to their linux machine. I just wanna transfer stuff from my old phone's sd card.

You need libraries that are able to access the MTP device. I don't have anything to test on right now, but this looks promising:
slackbuilds.org/repository/13.37/multimedia/mtpfs/
found this too:
wiki.archlinux.org/index.php/MTP
(sorry, I can't post real URLs because I haven't posted enough... just add the usual prefix to this.)

That doesn't seem to be the problem. I can't switch it to mtp mode. It shows up mounted as a camera, but then I get an error saying that it can't be unlocked or something like that. That was what I meant in my original post that I think it's still in PTP mode, which is why your suggested method didn't work for me. Thanks though. There should really be more support on linux for this if Google is forcing people to use MTP transfer now instead of UMS, which was universally supported... and better in my opinion.
Nexus 9 to PC
Hi, this is my first post on any forum anywhere! usually i can google my way out of the problem, but i am stumped - it might be possible there is not a solution......
I have a nexus 9 with Word app, on which i create documents for work in .docx format. i need to transfer them to my PC for printing and further editing VIA USB as work policy won't allow the tablet to connect to work wifi or to use Cloud transfer.
I connect usb as MTP, see 'Internal Storage' - cannot find any of the word docs anywhere, i have tried to save them on a bunch of different places in the Nexus but still no joy. All of the guides i have seen end at the 'internal storage ' part and then say 'just transfer between pc and device'. I have been able to transfer pc to android and edit on Nexus, but then re-reading the file on the PC it is flagged as 'corrupted'.
Is there some software for the pc i need, or is it simply $$%"£"""£££ and i need to get a MS tablet for work?
thanks for any help!
Have you tried OTG cable? I normally use the cloud option or just have my work saved via email, but you certainly have the option to connect an OTG cable to your device with a flashdrive and use a file manager app to transfer files over while avoiding corruption.
