Fix for USB Mass Storage...

I've recently installed Android to NAND and was looking for a way to mount the sdcard as a usb mass storage device in windows from within Android. I came across an interesting widget on the Android market called "Dual Mount SD Widget":
http://www.androlib.com/android.application.com-protocol-usb-jBAw.aspx
So I downloaded and installed it to see if it really works... well, IT DOES!
I used voguimg-320x480-17-02-10.nbh and Plemens Android Feb 8th build.
Here's what I did.
1. Download widget. Install. Add to Android desktop.
2. Tap on it. It will say "SD Split"
3. Plug in USB cord to the phone.
4. Notification area says "USB Connected". Don't do anything (ie. Mount it).... Instead, wait about 30secs to a minute.
5. Vista pops up the default actions window for the sdcard. My Computer also lists the sdcard as a removable drive.
I've transferred files back and forth with no problem. Not only that, Astro can see the SD card contents as well at the same time.
Now, the interesting part is that the description for the widget says:
"This widget Modifies a setting that will allow you to mount your SD card to your phone and PC/Radio/ect at the same time."
I'm wondering what setting was modified and if it is possible to build this in so that we don't need to use the widget anymore.

GREAT find! I am testing right now...
EDIT: Works excellent! It doesn't seem to be in the market for me...maybe because qvga, but I found it online.
I'm running:
Windows 7 Home Premium 64-bit
ADB Drivers installed by PDANet (not that it affects the SD mount)
Sourceforge 2-14-10 NBH (240x320)
Myn's Warm Donut with Hero theme.
This is awesome!
EDIT2: I can also run ADB/tether with PDANet and use mass storage simultaneously.

This is Fantastic!! It works. Great find man. didnt find it on the market but i did find it on the net. im using version 1.6
EDIT: you should take off the "possible" from your title as it is a perfect fix

Working perfect with Myn's Warm Donut + Windows 7 64 bit. Thanks for the tip!

Definitely works! (Using Ubuntu Karmic)
I was only able to find version 1.0 on the net - couldn't find it on the market.

How do you get it on the phone? Then how do you install it? All I have is a .apk file...what do I do with it? Vista does not recognize my phone, and I do not have a card reader. Thanks.

$1 in market. works great.

Sweeeeeeeeeeeeeeettttt Luv it luv it and luv it some more...

Man do us a favor and pl take off "Possible" from the title. This is THE fix.

Could you remind me why it's not possible without this app? is it a kernel or user space issue?
A long time ago, dzo told us that this could be solved when nand boot would be ready. Now, that's ready, what avoid solving this problem?

How fast is USB Mass Storage with the Vogue? Does anyone remember the transfer speeds it's rated for?
I'm using a class 6 MicroSD so I guess the card reader method will still be faster for me?

as I recall the notion was that running from nand would allow us the option of dismounting the sd card from the system so it could be used by USB mass storage. currently, nand still uses a cache on the sd card, so this is not yet possible.
this program allows both the system and the usb mass storage to access the sd card at the same time. I'm sure if someone cared enough to backwards engineer this we could incorporate something similar. however, why bother when there is a perfectly usable program already.

So this won't work using ext2 or fat for haret users I assume?

I'm running haret on a partitioned card (fat 32 and ext2) and it works great for me - just tested it.

~500kb write and ~800kb read (with class 4) results may vary

I confirm this also, running fat32 and 2 512Mb ext2 partitions. this is very handy. I found the 1.65 version doing a Google search, and that is what I have tested.

I would love to find out what this widget is doing so we can add the functionality to the base roms. I haven't had a close look at this yet but does anybody know exactly what it's doing?

So correct me if I'm wrong, but it would seem that if your SD card is class 4, this will still be grossly slower than simply taking the card out and using a card reader, no? 800 kb vs 4 mb / sec? or do I have the figures wrong... For small files this is convenient but for large amounts of music files etc it probably is less practical - granted not eveyone has a card reader

Right - unless you're running off SD card and can't take your SD card out . . .

[Q] saving backups/photos to SD card on D3

Why the hell won't my phone save my songs from Spotify, my photos from Vignette, videos from the camcorder, and anything other data the apps create??
Where the hell is the option to save on SD card?

Simmah down.

The actual SD card is mapped as /sdcard-ext/ in the filesystem. The /sdcard/ mount point is the internal storage. Apps need to be written so you can choose the storage location, and this will only be a larger problem going forward because as internal storage space goes up, more and more manufacturers will be doing this.
The built-in camera app does ask if you want to use the real SD card when you put one in and load the program.

Yeah, see I use Vignette so that doesn't help... geez.
Guess I'll have to make sure the main camera app is at least on SD card storage. I don't remember if the video files are automatically saving to the SD card (I did notice the SD-ext difference and figured that was the external vs internal memory).

If they're not being stored to the external on the stock app, boot the phone without the SD card in the phone, launch the camera app, then shut the phone down. Pop the SD card back in, boot up and launch the camera app again. It should say as soon as you launch that a new SD card is found and ask if you want to use it.
Going forward, /sdcard-ext/ is going to be more common on more phones, so app developers need to start providing an option for where users want to store data files. I'd contact the Vignette developers (they're pretty responsive) and let them know that they need to add a feature to choose the storage location of saved pics because most likely all Motorola devices will be set up this way going forward, with other manufacturers following.

Strange file system issues

My file system is totally confused. When I browse to EMMC from a file manager it goes to my SD Card. If I browse to SD Card it actually goes to the internal drive.
I've had my rooted Nook Color for about 5 weeks now (CM7 booted from a SD card). Everything was working great until I tried installing some different launchers. I tried GoLauncher, Zeam, ICS, Honeycomb and maybe one more. The default was ADW. Maybe I confused the system by constantly switching from one to the next but at some point the system crashed and I rebooted.
Once rebooted I noticed that many of the games I installed told me I needed to redownload their data files. I looked on my card, through my Mac, but the original files were still there. Turns out the Nook now installs apps on the internal drive rather than the card as it had been before.
Wouldn't be so bad but, as mentioned earlier, the file system is confused. When i need to manage files I've loaded on my SD card I have to browse to EMMC and vice versa. Makes my head spin.
Is there a way to fix it without starting from scratch? I'm using CM7.2.0.
Thanks for your help

That's not a bug, it's a feature. Anyway, what you likely did is Settings -> Cyanogenmod Settings -> Application Settings -> Use internal storage (checked). If you do this, then it swaps the mount points for the SD and the internal memory, so the SD card is mounted at "/emmc" and the internal memory is mounted at "/sdcard". See the first post in the thread in my sig for more information about this.
If you really want to return it to the original way, wasting 5G of internal storage space, then you can uncheck that box in the settings and it'll go back to normal.

Thanks for pointing that out and glad to see there's an easy fix. Seems a bit confusing though, like it's renaming your hard drives or something. I had been using the internal drive for storing media files, video, music, comics. Does it matter where apps or files are stored?

Well, the "fix", IMHO, is to leave it with them swapped.
Yes, it matters where apps are stored and it matters what is mounted at /sdcard. Apps use space on the /sdcard partition for settings, temp storage, downloads, etc. Mounting that 5G partition at /sdcard instead of /emmc allows these apps to use that space rather than cluttering your actual SD card. And apps are going to wind up on your 1G partition, not on either the /sdcard or /emmc mountpoint.
You can go read up in my guide on my recommendation on how to best use this space. The normal way is inefficient and wasteful of internal memory, IMHO. But you know, maybe you like it that way

I think efficiency is more in how you choose to utilise the spaces rather than fundamentally in which switch option you use. For example, I choose to completely fill the 5GB of internal with sound and picture media as they get included in the normal app scanning process. Leaving the SD card to hold yet more media, app data and back ups.
It's still good to have the choice offered by the switch.

[Q] Scanning media (SD)

Hello dear
I've got a 32gig Samsung class 10 card. Every time I turn on the phone, it takes about 5-10 min to scan for media files in the SD card. Is that normal? I cannot take some screenshot to prove it (Quickmeno doesn't take screen in the notification bar), but it takes a long time for me (my old DHD didn't take so much time, indeed didn't show even the message of the scan).

I've always had that too, with all my devices. Are these microSD card filled up with allot of data?
I think this is necessary to update changes in the Android OS. Like for example: update your mp3 songs list or picture gallery, check for apps on the microSD, ...
Maybe there is a setting to disable that?
I'm not bothered by it, I just let the phone idle for a moment. I have a Class 4 card, so it even takes longer for me xD
Edit: It could always be related to the microSD card. If so and you're running on Windows, just copy all the files to a folder as backup. Format the microSD card with default cluster size. And right after that go to properties of the card to scan for and fix filesystem errors and bad sectors. Copy your files back to the card and try again to see or it takes the same amount of time.
If you have very important data on that microSD card I recommend to also backup an image from it through a backup tool.

The best is unmount the card on the phone, "erase SD card" and mount the card on the phone, guess thats how the phone format the card.
Do a backup first, I think that unmounting and mounting will delete your data, what is normal...
Some devices only accept cards formated by themselfs, cards formated in a computer don't work on them, not saying that is the case but, it will be better I think.

Same
Same here. It's really irritating. I was about to ask for solutions. I guess it's the phone's problem since my other phones like O2X don't experience that at all.

I just tested again with my Class 4 32GB microSD. It has about 12GB data on it. It takes only 1-2 minutes for me.
Looks like something is going wrong with your phones than?
Maybe you can try this app: Rescan Media Root, and disable scan on reboot.

Folders contained a file named .nomedia wil not be scanned. You can create this file manualy for every folder without media files...
But using StudioKUMA .nomedia Manager from Google play can make it more easy

Try an app named "Rescan Media"

Auto install app from SD card

Hello,
I would like to know how I can make an app on my sd card...for example...es file manager...to automatically install itself onto a android tablet once inserted into the tablets sd card slot. I think scripting may be involved but I'm not sure. I have done nothing.
Thanks

Titanium backup should be able to run a Tasker app command..
haven't tried it though

Tasker
Thanks for your reply.
I'm wondering if is possible for an app to auto install without piggy backing on another app.

Not quite. The Titanium backup will be necessary on the other device as well in order for an application to auto-run itself.
I am more interested in learning how to make apps I download to a chip auto install itself once I insert that chip into another device. Something like what a CD does when you put it into a computer.
Is this even possible?

I bought this very cheap off-brand Android OS tablet off FB sales and it is limited to its pre-installed games. I can't do anything in the settings menu except view/uninstall the pre-installed apps and set the clock. This tablet doesn't have any USB ports, but it does have a micro SD card reader, headphone jack, and DC charging port. The card reader reads and plays (through the factory installed media player app) mp3 files and mp4 files on any micro SD card I place in it. I tried placing a micro SD card with other file formats (apk/pdf/epub) on it but nothing happens besides a notification saying, "SD card mounted." I am looking for a method that will have any APK ( specifically a file explorer app) on a micro SD card I insert auto-install or at least have the "install" dialog box pop up in order to expand the capabilities of this crappy tablet. Thank you for any and all assistance.

Okay, thanks for the explanation. I can tell you now, without any doubt whatsoever, that you cannot do what you're asking. You hit the nail on the head when you called it a "crappy tablet".
Without USB you're left with no options other than to install what it already allows you to install. Honestly, I'd say ditch it and get another cheap tablet, but make sure it just has regular Android on it and is not locked down.

Crap
Thanks for the information. I love saving a buck or two. I was really hoping to put movies, music, and apps on there for my daughter. I thought for sure I could get file manager on there some way.
Thanks again
