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

[Q] Mounting multiple usb drives via hub

So, I have a USB hub and a couple flash drives. Everything "works" fine. I say it like that because the hub functions fine, and the first drive you plug in mounts to /usbdrive just fine. The issue is with the second. When you plug in the second drive, Android sees it in /dev/block as sdb1, and using the Terminal app I can manually mount the drive and use it.
Ideally though, it'd be nice if there was a way for Android to see the second drive and automatically (dis)mount it to something like /mnt/sdcard/external. Is this something that can be configured in the system?

What about the way Android detects and mounts an initial flash drive currently? Does anyone have any knowledge of how that's working currently? Perhaps that could just be duplicated to work with a second one?

This might help.

I'm not sure that's quite right. From what I'm seeing, that tool is designed to let you mount existing media on your device in a way that makes it available to a PC. I'm just wanting the tablet to mount a second USB drive so that it's available on the device itself.

[Q] G2x as a 360 memory stick?

I did a search, and I couldn't find anything on it.
But I wanted to use my G2x as a memory device for the xbox 360 (to move game saves and such). But when I plug in the phone and enable usb mode, it doesn't show up under "storage devices", where it should be if the xbox recognized it.
I already tried formatting the drive to fat32, and still no luck... Any help?

you need to install drivers to mount storage on a pc, so I'm guessing it won't work on a 360 for that reason

Try "mass storage only mode" under SD Card and Phone storage in settings!

Ah. That does make sense. :/
I did try the solution that the poster above mentioned, but it still didn't work. Looks like I'm off to walmart to go buy myself a sandisk usb.
If anyone else has a solution or any ideas, it's never too late to post them. Maybe someone else will try in the future.

Ah darn, I had heard that would mount the external SD card on a PC without any drivers, but haven't tried it myself yet. You are using an external SD card?

Its not just the drivers. I know for a fact My 360 would read my stock G1 and with the earliest cyanogen roms, posibly as well with my N1.
once the rumors started about the "zune phone" which became the windows 7 phone media sync broke and xbox wouldnt see any of the phones. long story short M$ blocked you so W7 phones have an advantage

My car has a USB port and I can plugin to it USB thumb drives and I could also plugin my old MyTouch 3G to it and I could play music off of them.
I cannot play music on my phone through the USB port. I assumed it was because of the drivers issue, which is REALLY unfortunate because that was great functionality...
Anyone know if these issues persist after rooting and loading a Cyanogen rom?

That isnt what this thread is about. this is about the ability for xbox to read android phones. it used to, but now it does not.
your issue could be one of a few things. anything from your specific rom to making sure mass storage mode is checked or mounting the USB when prompted. Im not sure how yours works as I prefer the AUX on my head unit

Apologies, I searched the forums and stumbled onto this, as I read through i thought it could be related and put in a reply.
I never get the prompt on my phone to mount it...which is what prompted me to search the forums. I'll keep looking

[Q] How to mount only external SD?

Whenever I plug in the phone to my computer via USB, it loads it as two separate drive letters. This is fine and good for the PC side of things.
The problem is that I want to be able to use the phone's external SD as a mass storage device that attaches to a new car's USB port. The car always throws back an "unsupported" error, and I'm betting it has everything to do with the fact that the phone tries to mount the 2 cards. The car just doesn't know how to handle that information.
So, does anyone know of a tweak or setting that would force the phone to only mount one or the other, preferably the external?

I've removed the external SD card and plugged the phone in to the car. It doesn't error out now, but I didn't give it ample time to find music hidden in the internal SD.
That being the case, I still would like to know if there is a way to disable USB mass storage for one or the other without having to shift things around all the time. There's a reason why all of my music is on the external SD--it's a 16GB card and I have a ton of music.

The only way I can think of is by mounting it in clockwork recovery console. That would give you access to the music...but you'd lose the functionality of the phone during that time, so doesn't seem like it would be a viable route for you to take...but I suppose if you wanted to do bug testing to see if your external WOULD mount to your cars usb, that's one way to check that out.
Hope this helps.

I'll give that a try this afternoon. You're right, though, it does defeat the purpose--I'd really like a functioning phone while I drive. I'm sure there's a way to adjust this, I just don't know enough about the inner workings to make it happen.

Hello devitec,
I have the same Problem in a BMW with a Samsung Galaxy SII phone. I have no satisfying solution but I can use below workaround.
The BMW cannot mount both drives, but he chooses randomly one of the two. Because there are no music-files on the internal sd, it gives me an errormessage. On every second try i get the external sd which is browsable like a usb-stick. The album- and artist-informations are not parsed for the BMW-filterfunctions, so i can only choose by directory.
I hope this workaround will also work in your car.
max01001111
P.S.: The Samsung galaxy SII has to be in debug mode to mount without kies-support.

what if you guys try to unmount the internal sd before you connect ur phone to ur car?

One S USB mounting problem

Hi all,
Apologies if this has been answered elsewhere but I have looked and cant find anything.
My One S is Jelly Bean 4.0.1 (un-rooted)
The problem I have is basically this.
I have a Micro-B Usb Otg On The Go Cable and Integral MicroSD USB Card Reader with a 32gb Micro SD.
When I first put all this together and plugged into the USB slot of the phone everything was fine, the little red light on the Integral MicroSD USB Card Reader was lit up. The message of Unable To Charge Device was coming up but the phone was also mounting the storage for reading via Astro File Manager no problem, so I was able to play MP3's and 4's and so on. But then it literally just stopped reading the Micro SD card and the Micro USB Card Reader is not lighting up at all.
Any help will be greatly appreciated as I am at a lost as to why it would be working perfectly one second and then not another.
Thanks you.

Follow up.
Been doing a little bit more looking into this and it looks like it has to do with USB hosting. Is there any reason my phone would just stop hosting a OTG USB Flash Drive? As i mentioned before it work fine for a while and literally just stopped recognizing that there was any Mini Sd attached.

You seem to be stock so not sure what's up with that but could try factory reset in the bootloader has long has you haven't changed recovery but backup what's on the SD Card because that will get wiped too.

Thanks Darknites,
I have reset hard from the settings menu, does it make a difference if i reset from bootloader? I have downloaded USB Host Controller and look at what results I get from running that and I get the SC3 USB Host Driver Not Found which I believe is something to do with the chip set which doesnt apply to my phone but I also get the message of USB Root Hub Present but I also get Not Present sometimes when re-running and the same with USB Host Mode is Active and then sometimes Not Active after re-running the Host Controller App.
I did read somewhere that its possible that certain chip/chips might have been damaged/fried by an extended use of USB Hosting to a flash drive, is this correct?
Thanks again for the reply.

I havnt heard of that in YEARS, and even that was in most cases a false rumor. I have never encountered a chip dying by being used properly.
If you short-circut the cables or something - then yeah, thats a different story.

Ya in bootloader everything gets wiped even sd.

I did cross my mind re the cable because the drives are fine in my PC, I know they are powered there though. I might try another OTG cable, there cheap as. Its just strange that one minute the Micro SD drive was working perfectly and then kaput.
