Applications SD access while in USB mass storage - Galaxy S II General

Hi People.
Sorry if this isn't an appropriate forum to post this.
I am trying to connect my SGS2 to car radio through USB cable to access music files.
First, there was a problem to even connect the phone to the radio and the car told me that there is an error connecting to the device.
But after turning on USB Debug mode on the phone, now I can connect (Although after 2-3 attempts, why ???) to the car and it finds all my mp3's on Internal SD.
But now there is another problem. Because the car now uses the SD card (As Mass storage), any application that trying to access it is denied.
So when I'm trying to use Waze for example while listening to music it writes me that Waze can't access my SD card.
Is there a workaround to be able to use the SD card from both the car and the applications at the same time ?
I'm using Lite'ning Rom v1.4

Search in the market for dual or multi mount.
Sent from my GT-I9100 using XDA Premium App

Multi Mount SD Lite - doesn't work.
All is the same as it was, when I mount the SD the applications can't access it.
Maybe I'm doing something wrong ?
The notes say don't use android mount feature.. what does it mean ?

Anyone? It's really annoying that I can't hear music while navigating..
Please help..
P.S - If I'll buy external SD card for music, will be there an ability to mount only it, so the internal will be for the applications and the external for the car radio to mount ?

Ok, the question is still open.
Is there any real solution, like patch or something ?
Because both Multi Mount and Dual-mount doesn't work.
If I use those apps the car can't even find the phone as if it is not mounted. (With the built in mount feature the car finds the phone on the 5 try or something..)

any answers as follow up? i got myself a dension gateway 300 and when i try to plug in my galaxy s (2.3.4) i have the same problem.. multi mount sd manages some time to do the trick.. but its very random..
i am thinking that the android system is "fighting" with the multi sd app. and it manages to mount the internal storage or something like that. ]
does anyone have any hint?
cheers

My guess is that the Dension only mounts the first partition it sees (i.e. the /sdcard directory). At least that's what I've seen with memory sticks I've tried to put into my Gateway 300 -- I haven't tried mounting the SGS2 since I have all the same music on a dedicated 32GB microSDHC card & USB card reader.
Anyway, if the Dension has mounted the /sdcard directory, you should be able to access the SD card through the external_sd directory.

Actually it does not seem to mount any of the partitions. if i check at the source menu it says "no usb".
when i use "multi sd mount" app i can sometimes get it to work (setting the app to mount only the external sd) but thus is only once every ten tries. i cannot do it at will...
it seems somehow that the android mass storage software and the app are "fighting" somehow. (of course the android on its own does not succeed).
may i ask you to check if you can mount your galaxy on the dension? not many have this configuration so your feedback would be valuable.. thank you in advance
cheers

Can't Mount SD Card

Hey Everyone,
I apologise if this is in the wrong forum (not sure if it should be in Android Development), and before I start I want to make it clear that I DID use the search function, I searched for "Can't Enable USB Mass Storage" and "No option to mount SD Card" with no relevant results.
Rom: JFv1.51 CRB43-EU
Ok, I was using my phone fine I managed to sync around 12GB worth of music and transfer a few files last night (I flashed the ROM around 20:00 GMT after trying out several hero builds).
This morning I mounted the SD Card to my laptop (OS is Windows 7 RC1) and transferred a few APK's. Suddenly as I was in the market the phone comes up with "Checking SD Card for Errors" and had for some reason unmounted itself from the PC.
Now when I plug in the USB cable all I get is the light to indicate it's charging. There's no option to mount the SD Card. I've tried it on my Laptop, My Vista Desktop AND My Xbox 360 (usually there's a mount option when you connect to that which allows the xbox to see music on the phone).
Strangest thing is the MicroSD Card seems fine, I am able to play my music and see the 2 pictures I have stored on it. Another site suggested using Anycut to make a shortcut to SD CArd and then ticking Enable USB Mass Storage. This doesn't work either, I get a ! in a triangle in the status bar saying USB Mass Storage Enabled but neither my laptop or my desktop will pick it up.
Any Suggestions?
Thanks,
Steve.

Yep, Should it be?
Yes it should be. Try uninstalling and reinstalling the drivers (USB mass storage devices)

[Q] Does mounting the sdcard as diskdrive really screws up a2sd?

I've read somewhere here in the forums that it can screw up the a2sd function
so how can i connect the phone to my PC (because using a card reader every time you need to connect your phone to a PC is @[email protected])
Is this true? any alternative?
I'm using wildpuzzle ROM btw
Hi Dudin.
As standard, when you connect the phone to the pc as a removable storage, Android prevents the SD from being seen by the phone at the same time. As A2SD installs apps to the SD, this obviously causes any Apps on the SD to not work. I dont think its a permanent screw up, as it all should right itself after you disconnect from the computer, but you do have options:
1:Connect as Sync or Charge only. (a quick but pointless workaround if you want to browse your Sd card from the pc),
2: Or do as I do and install "Dual Mount SD" from the market It makes the SD card accessible by both Android and the USB at the same time. Works perfect for me, I can still use my aps and access the SD from the PC simultaneously. (I have used it on Wildpuzzle, Openfire and Cyanogen Mod, Eclair and Froyo versions). You need to be rooted for this though as it asks for superuser permissions.
Hope this helps.
Ok I will clarify for you. If you use dt app2ext patch. When you mount your sd card, the computer mounts the fat32 partition, and does not detect the ext partition, so it does not screw your card up, or the apps.
if you are using froyo app2sd, the apps that are on your sd card will not work when the sd card is mounted.
thanks for the replies
I find a good alternative is Dropbox - and it is mentioned in a lot of threads.
I already used it for work and it is great. No looking around for a USB cable or turning off/remove case/remove card etc which takes ages! Dropbox is free so give it a go! I use it in conjunction with EZ File manager (i think thats what its called) to transfer stuff and unzip archives.
Hope it helps!

Tutorial: how to use a nfts microsd in your p6800

I confirm it!
1 format your mocro sd on nfts using wimdows 7
2 insert the card in your 7.7 and dont care of the tablet says that the card is invalid
3 launc mount drive that is free on android market
4 unchek device filtering
5 select the last bottom drive that is the only one nfts drive avaiable
6 tap the upper right button, the one that have the icon of a drive
7 now you should see in the right colum your drive with a bar thar rapresents the free space, if you cant see this, reselect the nfts drive on the left colum and retap the mount drive icon (upper right) until you can see the drive mounted on the right colum.
8 when your drive is mounted you can find the drive folder with a root enable file manager like honeycom fm hd, the folder is under the system folder named mnt
Tht is all it works fine amd you cam close the app drive mount, the tablet comtinue to recognize the nfts micro sd wothout the app running. Now i can put my hd movies larger than 4 gb inside my micro sd and play them with my 7.7
The only problem is that tje sistem apps are setted to save thinks in mnt/externaldevice, so if you want save you movies or photos taked with the 7.7 camera inside your microsd you cant do it, you have to move them from your tablet memory to your microsd nfts using a file manager, but this is a little problem nothing of big
If any brave user is able to tweak the camera app to save the moviesnor photo inside the path mnt/nftsdrive please do it, after this all is perfect. Thanks
thanks!
btw, it's called NTFS, not nfts
Yes you are right, i do ever this mistake xD
Do you need to root your tab ?
Yes root is needed
Thanks.
I got it to work.
But there is a problem.
How can I transfer a 6 GB file to my 64 GB SD card using usb cable connected from my desktop to the Tab 7.7 ?
Currently I have to take out my SD card from my tab and using an adapter to transfer the movie to it (from my desktop to the SD card).
This is a tedious process and I don't want to keep taking the SD card in and out of my tab. I want to transfer my big movie file straight from my PC to the tab when it is connected via USB cable.
Currently, when I connect the tab to my desktop, I only see the internal storage of the tab and not the external NFTS sd card.
yes i know, this is a big problem, but unfortunatly i am unable to solve it, becouse the sd is mounted in a different place,in the origins the card id in mnt/externalstorage, but with the app drive mount tha parh is different..

perhaps softlinking the path may help?
it can help, but how to do this?
Maybe by transfering from your desktop to the tab using Samba through your local network (ie wifi instead of USB) and a SAMBA app on the GTAB ?

Yes i know this method, but this is only wifi , it is more slow than usb. To do this just install astromanager and configure a spb network with the ip of your computer, after this share a folder from your pc and then you can copy files from your pc to your tab microsd via wifi
I've just made an app to mount NTFS sdcard.
It allows you to use it like normal FAT32 sdcards,
working with Stock camera app or MTP file transfer.
Could anyone try this?
I'm going to put this to android market
and I've already purchased a developer account,
but it seems to take some time to be able to upload my app...
My English is not good, I know
If there are any weird wording, let me know.
** alpha version **
** only for root users **
** only for Galaxy Tab 7.7 ... for now **
This app is to mount SD Card using NTFS.
/mnt/sdcard/extStorages/SdCard is the root of sdcard.
Auto-mount when the Android OS starts.
Or you can mount/unmount it manually.
** Not Bug **
- If you don't do "Safely Remove Hardware"
when you take your sdcard from PC,
it takes some time to mount it.
** Confirmed Issues **
- Only NTFS sdcard use assumed.
This app may prevent using FAT sdcard.
- Once unmounted, even after you mount again manually,
Android OS don't detect the sdcard.
You can access it with file managers or other apps,
but stock camera and settings app don't.
(Let me know if you know any solutions for this.)
- At the first attempt to mount (and get permission for su),
Android OS could fail to detect the sdcard.
It may be caused by delay of Superuser asking if it's ok or not.
- No error handling
** Disclaimer **
I am not responsible for any damage caused to your device or data or feeling.
It is recommended to backup your precious data.
Perfect app!! it works fine.
For this point
- Once unmounted, even after you mount again manually,Android OS don't detect the sdcard.You can access it with file managers or other apps,but stock camera and settings app don't.(Let me know if you know any solutions for this.)
It is not enought to restart the device in order to let android and camera/gallery to recognize the ntfs card ? This will solve the problem?

Thank you!
Of course, after rebooting the device,
sdcard can be mounted and Android OS detect it as usual.
It seems initial booting and inserting sdcard trigger detecting process,
but I don't know how to let the os to do it by my app.
dont worry your app is awesome as it is it is not a big problem to reset for make it functional after the unmount, just specify it when you sell in android market. Thanks so much for the app
Pretty great app to bad i left my 7.7 at home once i get home this will be the first thing i try. Btw any plan for galaxy note ver too?
Thanks alot

I think it's possible to improve this app to work on galaxy note,
I don't have one though.
All I need is sdcard's mount point ( "/mnt/sdcard/external_sd" ? maybe ) and
device name which is like "/dev/block/mmcblkxxx".
If you can get these info, please pm me.
Thanks.
Thanks for awesome apk~
If you have any plan put it on the market, plz let us know.
We will support it!!
please hurry up if you want to gain money, becouse the huawei media pad woth ics of my girls can read ntfs micro sd, i think that with the ics update the p6800 will read the ntfs from defoult.

ICS missing the "Turn on mass storage"

if i connect my usb cable, the drive appears - however i dont see that icon in ics to turn on the mass storage.
The icon etc should be on the notification bar, but its not there anymore.
I can use the usb storega. I'm running v1.9. Are you sure your cable is working and drivers are installed?
yeah it is... i just upgraded to ics, it also detects the "debugging" and the drive appears on my pc.
Little progress now... after some middling in recovery the option is back... however... it just keeps on trying to turn it on..
what i noticed in recovery was that i couldnt mount sdcard (mounting error).. and a "unable to write ums lunfile" when i tried to format it.
but card is working (eg if i go for the upgrade from zip etc option... i can browse the internal SD)
in File expert it shows the sdcard as 0/0 kb (and when i open it... it just points me to the internal memory)... under storage in settings it still shows that 2gb internal SD.
Which version of CWM recovery are you using? Pretty sure I've read somewhere that to make things work properly for ICS you need 5.5.x.x. Was in the ICS thread in Development iirc.

Take sdcard out of the phone and reinsert it and then try to plug the phone to pc.
i cant take out built in sdcard....
and as for the cwm. it should be the 5.5.0.4
Ics by dzo doesnt mount internal sd. It only mounts external, maybe thats is why you cant mount using usb?

[Q] External USB drives (HDD/SSD) And Mounting

[Q] External USB drives (HDD/SSD) and mounting
How does the SATV decide what directory it will mount an external USB drive to?
/mnt/media_rw/usbdrive
/mnt/media_rw/usbdrive2
/mnt/media_rw/usbdrive3
I keep noticing mine will change from one to another each time I reboot. This is really messing with Foldermount. Does it matter what other devices are plugged in? How can I force it to a certain one? I am rooted so if this can be done from terminal, I assume it's *NIX like, I'm all ears
thanks
Mine is mounting the same every time. Make sure you are connecting to the usb port every time obviously.
I personally use stickmount to mount inside the sdcard directly.
In my situation I have a SSD in an external USB 3.0 chassis that is always plugged in, same port. I just allow the OS itself to perform the mounting and have never had an issue where it didn't mount, it just intermittently changes the mount location it is using.
The big problem here is when it switches it screws up any app that previously had the drive noted at the last known mount folder. Foldermount being the main app but others like emulators lose the last folder used too.
Is the mounting process on an Android device similar to Linux? Will I find some config file that I can edit to force the mount location every time? Although I'm not sure why it changes sometimes, not all the time, on restarts of the device. For now I've been trying to not restart unless really, really needed.
I also use the same setup minus the fact that I use stickmount also. The system will still do what you are discribing, but it will also mount within the SD card in the same place every time for me.
