[Q] Media Device(MTP) Mounting Issues? - Eee Pad Transformer Q&A, Help & Troubleshooting

Ever since upgrading this to a rooted and custom ROM(Android REvolution HD, right now), I've been having issues with any sort of computer connection. Most notably, anytime I connect, the internal storage mounts, albeit it oddly takes it a while to accept that files are there and display them, but the external SD card never properly mounts. It can display information about the SD card, even how much data is used. But it shows absolutely no files on it. Is this an issue with the SD card(I'm guess it's not since even the internal has problems), and how would I fix this?
[EDIT] Noticed a question related to Media connecting. Is there any way to access files on the internal and external SD card using something like Total Commander?

SD"2" Mount Issue

My first thread that I can call my own.
Question for you all. Is there an easier way to transfer files over the the GTAB then having to pop out the SD Card and put it into an adapter and then into the computer and then out of the computer, out of the adapter and back in the GTAB?
Because every time I mount the USB, it only mounts the "internal" SD Card. Is there some sort of way to get it to mount both the internal and external SD Card?
I hate messing with the external SD Card. All the "popping in and out" makes me nervous.
I even tried mounting the internal SD Card and then copying the movies/music/etc.. over to the external SD Card via a file manager... but that is DAMNNNNN slow.
I haven't found a way (yet). Given that neither the zPad or TnT stock builds work, I'm thinking it's not that easy to do. Drives me nuts as well because I really don't want to keep taking the card out over and over and potentially damage it, over time.
That's exactly what I am worried about. LOL
I can just picture not paying 100% attention and snapping the card in half or, breaking the "locking" mechanism that holds the card in place.

If you have ADB, can you do adb pull or push?

My workaround has been to use the LAN tab in ES File Explorer to copy data wirelessly to sdcard2. Probably not the speediest method but it keeps the card in place.
The techie/hacker solution to easy file transfer is to use the Rsync for Android app in the market store. Once you have it setup, (not the easiest thing to do) it works great for moving files automated from your gtab back to an rsync server (my linux box to the rescue). I even have a secondary profile to get it to reverse rsync a specified directory FROM my linux box to my gtab. Presto -- easy file transfer via wifi!!!
Also, another idea might be to use Dropbox?

I do the same thing. It's mighty slow, but it works.
roebeet - an idea that almost worked - maybe you know why?

Hi,
You all got me curious, so I just tried the following:
- Created a dir under /mnt/sdcard, /mnt/sdcard/mymnt
- Get temp root (z4root)
- Start terminal
- su
- mount -t vfat /dev/block/vold/179:17 /mnt/sdcard/mymnt
At this point, I can access the sdcard2 by using /mnt/sdcard/mymnt or simply /sdcard/mymnt.
So, I disabled USB debugging, and I get the popup asking if I want to activate USB transfer (I'm on 3452, on earlier TNT firmware, it use to say enable USB storage).
I click the button to Activate, and then another window pops up, and I click Activate.
Then, the popup just stays there, with the spinning thing. It never enables USB transfer, and, on my PC, I see the removable drive, but when I click on it, it says it's not ready.
I've also tried umounting /mnt/sdcard2, thinking that it might be confused because of the two mounts to /dev/block/vold/179:17, but it still does the same thing.
So:
- It looks like I can mount the /dev/block/vold/179:17 (the external microSD card) under /mnt/sdcard, and
- When I do that mount, I can see the contents of the external microSD card in terminal under /mnt/sdcard/mymnt and under /sdcard/mymnt, but
- For some reason, turning off USB debugging/activatiing USB transfer fails.
Maybe someone can figure out why activating the USB transfer fails. If we can figure that out, then that would allow seeing the external microSD card via the PC USB interface.

I think it would need to mount both volumes -- the internal SDcard and the external SDCARD2 -- separately...
Using a mount (reparse) works internally since they are on the same device -- but if you try to mount SDCARD externally it doesn't understand the reference to SDCARD2
My phone actually mounts to the computer as two drives -- one for internal (SDCARD) and the other for external (SDCARD2)
I'd assume there is a way to have something similar work on our gTablets...
I'll have to slap a spare microSD card into the tablet to try though...wondering if teh INF needs to be tweaked as well (??)
From what Ive seen or experienced, Cyanogen was the only rom that Had the Sd card and Sd card2 Thing fixed right (with exception of having to plug in the Power cord before mounting). Evrey other Rom seems to have problems. But Cyanogen has way too many other problems so I use Vegan since to me it seems the most stable :s
Yeah -- my phone is running a fork from Cyanogenmod 6...so the code is shared

That's the problem... When the Gtab is plugged into the PC USB (while USB debug is disabled), only one new "drive" appears, corresponding to /sdcard on the Gtab. There is no 2nd drive appearing on the PC corresponding to /sdcard2 on the Gtab.
I've been looking at my Windows configuration, with the Gtab plugged in, and the one drive that appears shows up under "Portable Devices" branch in Device Manager. The properties show that it corresponds to "wpdfs.inf", and looking through that, it looks like a generic USB Mass Storage configuration, i.e., a USB drive.
I still think that something would need to be fixed on the Gtab end for the two drives to appear on the Windows end.

app fix
I have found a workaround for the issue with the installation of a single app:
http://forum.xda-developers.com/showpost.php?p=12299831&postcount=2
Depending on what you want to do, an FTP solution is also possible as discussed in this thread:
http://forum.xda-developers.com/showthread.php?t=869844
By using swiFTP, I am able to open a connection through a Win7 windows explorer, and I can drag-and-drop files to SDCARD2 (over a wireless connection). I put a 1Gig movie on the card and it took about 12 minutes.
Another option is to use Multi Mount SD-Card. This is link is for the lite version, there is also a paid version.
This app works outside the embedded SD Card Mounting scheme that comes with Froyo.
With this you dont have to press the "Mount USB" button that comes up in the notification bar when you attach the USB cable. Instead it will auto-mount the either the internal or the external SD Card when you plug in the cable.
(Having configured the setting of your choice before hand).
Unfortunately it can not mount both at the same time.
It works with my GTAB and I'm using VEGAn 5.1 Beta.
(Without the 5.1.1 Suppliment patch)
Folks are still struggling with this?
Use a USB flash drive, I do it all the time. Just a regular, boring, Windows FAT-formatted flash drive.
Wow it is amazing that this problem still exists.
I am a new owner of a Gtab and have had it for less than 2 days. Thank goodness for the many informative posts on this site, that have helped me make my new toy almost perfect.
I updated to 3588, installed cwm and titanbackup, vegan5.1.1 including the suppl patch and even learned how to tether it to my Samsung Captivate. The one thing that was annoying me was my device not seeing the 16 gb microsd card that I had inserted both in the gtab and on my pc.
After reading this thread, it looks like I am not going crazy, but it seems like my device is destined to not acknowledge this addtional storage in it's settings?
I really was hoping to use the external card for videos and my mp3 collection, so I am missing something or did I do something wrong to make this happen?
I would appreciate any comments or suggestions since this is the only thing that I need to get squared away before I install more apps(with the possibility and ever present threat of having to re-install something I may have already done)
I could not post this question in the dev section since I do not have enough posts to allow me to.
Thanks

I am Freakin Lost.....

Ok Guys,
I have just done the rom swap on my tablet. Everything went fine and thanks to the easy direction builder....worked great. I have a few questions because I am lost. Please help me understand what I have here and how to fix the broke things if they are actually broke.
I can't read a usb jump drive from the usb port
My computer does not see the tablet now that I have changed the rom
Now for my lost part. I am trying to figure out how to move things around on this unit but I can't seem to make the sdcard and sdcard2 make sence. When I dismount the sd card I loose stuff on both sdcard and sdcard2, but when I mount the card again I get back stuff on both. I am trying to figure out which is which. I have heard the sdcard2 in the external but it just does not figure in my head. I hit the home button on the file manager and it brings up sdcard and sdcard2 along with a lot of other stuff. When I click on sdcard it shows all the stuff on the mini sd I have installed and when I click on sdcard2 it shows DCIM & LOST.DIR. That seems to be the internal but it is listed as sdcard2...what gives. Someone please get me up to speed. Also I had some tunes on here and there was cover art that showed when it played and now it is gone......no idea as to where it went.
Sorry for the newb questions but I have never had a tablet like this and it is all new to me.
Thanks
Brad
redbullsushi,
First, if you want more help you will have to give more info. You don't say what rom you are using, etc. That would help.
Second.....when you look at the file manager:
/sdcard -- is the internal memory of you tablet.
/sdcard 2 -- is the name assigned to the miniSD card slot with the external miniSD.
/usbdisk -- is the USB key (large) port.
Don't know why they named them that way but might as well get used to it!
Now sort out what you can and get back here with more info on your G-Tablet and the software on it.
Rev
Yea sorry about that
I am running Vegan 5.1
And I had read about the strange names but mine seem to be backwards. Everything that I think is on my minisd is listed as sdcard.....when i dismount my sdcard in the system I don't see all my stuff anymore and the sdcard shows a blank folder. The sdcard2 still shows the DCIM and LOST.DIR. So it appears to me to be backwards.
I also got the usb storage to work by mounting it in clockwork but the usb connection to my computer is still not working.
Thanks
Vegan does not properly display the microsd storage in the System Settings. When you dismount the sdcard in Vegan from the System Settings, it will dismount the internal storage as this is option in the settings is not referring to the external micro sd. You don't need to be dismounting the sd card in your settings really.
While in Vegan, when you connect the USB to your computer, a notification should pop up in the tablet to enable USB storage, you need to make sure this is turned on, then your pc should see the tablet, and it will see your internal memory (/sdcard).
Turn off your tablet and remove your microsd card and plug it into a card reader, I'm guessing you'll see the DCIM folder.
Ok,
so got the usb working...mine did not offer the turn on option. i had to pull the toolbar down from the top to enable that. should i have usb debugging on?
also, my computer does not read sdhc cards so if anyone has some info on updating a machine running win7 to read that it would be helpful. i have tried both my on board reader and my usb reader and neither work. i assume they are out dated and i need to buy another reader?
that being said how do i see my minisd on the machine other than it is listed as sdcard not sdcard2. i know this because when i hooked to the usb and connected to my cpu i saw all of the things that are listed on sdcard2.....arg
so i must make the assumption that sdcard is my external and sdcard2 is my internal?.......is that right?
Thanks
Also,
I have tried to move some tunes from the sdcard to sdcard2(external/minisd) and it says file cant be moved. I also don't see anywhere that my minisd size is listed......I know this is all noob to you guys but wow this is frustrating. I appreciate the help very much.
Thanks

You're not making much sense to me. Maybe I'm reading this wrong...you're asking how you can see your microsd on your pc (it's microsd, not minisd, minisd is a different format), but at the same time you do see it on your pc (which shouldn't be the case).
On your tablet, what do you see in the /sdcard folder? What do you see in the /sdcard2 folder? On your pc, what do you see when you've connected the tablet to your pc?
Sorry again.......i meant micro not mini. When i look at sdcard i see a bunch of files. When i look at sdcard2 i see the DCIM file. So when i connected to pc i took out microsd to make sure i knew what i was looking at. So sdcard is internal and sdcard2 is micro like you said. I am trying to get used to this.
My struggle now is the 2 avi apps dont play the avi i downloaded. I am also finding apps that wont install, and they seem to be the best of what i need ie: pdf ereader and avi video player. And i cant move files from sdcard to sdcard2.
And let me say dude thanks for your help and i hate you were the poor bast*rd that has tried to help. I appteciate it and if it woild be easier for you to chat on phone i will PM my cell.
Thanks
Get vitalplayer from the market. It plays videos well. My divx/xvid files play well using vitalplayer. It's also dependent on how your videos were encoded.

Micro SD help

I have my internal 16 gb all filled up about 95% and I bought a micro sd card which arrived today.
I began transferring media to the micro sd card under /removable/microsd/ and was able to transfer about 1gb so far of the possible 16gb.
i noticed when i would start a file transfer, i would get a pop up message saying the file "may be copied to the device for storage or transport use only. it is not supported for use on the device itself. if possible, use a media program that can convert the file before copying it. if you copy the file now, it will be stored on the device, but may not be presented in the device user interface."
however, i would get an error after saying theres not enough free space on the device when i began transferring my media.
wtf is going on and how do i transfer my media to the micro sd?
plug it into your PC and copy it to your PC then to microSD
yes, my tablet is hooked up to my pc. that is wherein lies the error messages i'm getting.
so it looks like when i cleared my micro sd and my internals and tried again it worked.
1) first i loaded my media onto the micro sd first
2) then i was able to transfer media to my internal storage
i find this strange because i was having errors loading to the micro sd card after my internal storage was filled up.
Where did you bought the microSDHC card? Did you tested it to full capacity and see if it's genuine?

I also get a message when trying to copy files to the microSDHC card (inserted in the TF) from the PC, but I just click to continue and they copy just fine.
yeah its real. transcend 16gb micro sdhc class 6 straight from amazon.
before i just bypass the message notification (hence loading about 2gb of media onto my micro sd).
when i tried to transfer more, i would get an error saying my storage was full. seems to be fluky.

Never quite understood internal storage vs USB storage on Nexus

What exactly is the difference between internal and USB storage on the Nexus S? It only has internal memory that's not expandable so why bother with the separation?
Also should I be moving apps to the USB storage since the internal storage of 1GB is 2/3 filled with apps?
The Nexus S uses a single 16GB flash module that is partitioned into two volumes instead of one smaller flash module and an expandable memory slot (SD) setup found in many other phones. The "Internal Storage" is the internal flash memory needed by Android to house the OS installation. The "USB Storage" is partitioned separately to allow the volume to be mounted, which lets you simultaneously use your phone while performing read and write operations on the "external" volume. If it wasn't set up this way, you would have to forego the ability to use your phone while it was mounted. It also allows you to erase and flash a new ROM without affecting "USB Storage" contents (photos, custom ringtones, music, etc.).
If your app has the option to be moved to "external" storage, the only drawback is that you won't be able to access it on the phone while the volume is mounted.
Oh, ok. Thanks. I never bothered using the phone when it is in USB storage mode, but it actually still works except some apps say "not installed".

The reason for this is that USB mass storage can only have 1 device access in at any time. if your computer is accessing it, android cannot This means that if you have apps installed to the SD card, they are no longer accessible to Android and as such, are considered not installed, disconnecting USB mass storage and letting the phone re-initialize the partition will "re-install" the program.
The other issue with the separate partitions is that you have limited space for "internal storage", on the nexus, that's around 1 gig, on other phones, it can be as low as 100 MB. Normally, this space cannot be changed, so you have to anticipate the needs of the customers when building the phone.
To correct this problem, ICS uses Media Transfer Protocol, for an explanation on why, look here. Interestingly enough the iPhone also uses a similar method for transferring files, only they have a custom protocol through iTunes rather then the more generic MTP.

[Q] USB Storage em Blu 4.0

Good Evening, I have this rom (http://forum.xda-developers.com/showthread.php?t=2295030)
installed on my phone works 100% ...
However I did something stupid this week, my phone was no memory card in the PC and connected it to move some files to the usb storage, however at the same time I was messing with a stick and need to format it by mistake ended up formatting the storage USB.
Now every time I disconnect appears "damaged card, you may need to remove" and neither to using the SD, put this warning is for internal storage, however I thought of formatting options in android, tab settings> storage, however this rom does not have the option to format and much less "mount" the internal storage.
So I'm without, thus prevented from taking pictures, listening to music internal storage ...
I wonder if you have any way to fix this?
Note: Connected PC normally recognizes the USB storage.
