[Q] How to swap sdcard-ext to sdcard mountpoint - Atrix 4G Q&A, Help & Troubleshooting

Hi there, I have a 32gb class10 sdcard, dont want to use the internal 10gb memory as the default place to save app data, since I have 20gb of gamedata on the sdcard\android\data and sdcard\gameloft\games, so how can I mount my 32gb sdcard to be the root\sdcard, and the internal memory to be the root\sdcard-ext just like it was when I have the CM7 rom.
No I dont want to go back to CM7, I want to do this on my original rom android 2.3.6 brasilian bell atrix.
I found a CWM recovey swaper to droid x, so it is possible, can you guys help me, some script or anything.
I already tryed to just rename with rootexplorer but didnt work.
I already tryed lots and lots of markets apps that said it would do, but didnt.
Can someone please point me a way...
Thanks a lot

I'd like to know this aswell... But in my case, I haven't done any research.
Will post if I find something.

k scrub-a-dub-dubs googling would have answered this question already and so would the XDA forum search, but since its the holidays i'll help you both out.
1) get Root explorer, and you're going to need root access. I'll wait.
2) Using root explorer traverse to /etc/vold.fstab. MAKE A BACKUP of this file!
3) find the two lines for sdcard and sdcard-ext/emmc (depending if you're on CM7) Lines should look like this:
dev_mount sdcard /mnt/sdcard BLA BLABLA BLAB etc etc etc
AND
dev mount sdcard-ext /mnt/sdcard-ext blaglalgalglaglaglalglagldslfgfl
4) ok simply swap the 2nd word of each line with each other. So the first line
would say
dev_mount sdcard-ext /mnt/sdcard BLA BLABLA BLAB etc etc etc
and the second line would be
dev mount sdcard /mnt/sdcard-ext blaglalgalglaglaglalglagldslfgfl
5) save the file and reboot
NOTES: blur based roms do SDCARD + SDCARD-EXT. CM7 does SDCARD + EMMC, but the same guide applies
goodluck and happy holidays

Thanks but that didn't work :-(
I changed mine from:
# external sd card
dev_mount sdcard_ext /mnt/sdcard-ext:none:lun1 auto /devices/platform/tegra-sdhci.2/mmc_host/mmc2 /devices/platform/tegra-sdhci.2/mmc_host/mmc1
# internal eMMC
dev_mount sdcard
/mnt/sdcard 18 /devices/platform/tegra-sdhci.3/mmc_host/mmc0
To:
# external sd card
dev_mount sdcard /mnt/sdcard-ext:none:lun1 auto /devices/platform/tegra-sdhci.2/mmc_host/mmc2 /devices/platform/tegra-sdhci.2/mmc_host/mmc1
# internal eMMC
dev_mount sdcard_ext /mnt/sdcard 18 /devices/platform/tegra-sdhci.3/mmc_host/mmc0
But even after a reboot both mount points remain unchanged.
Any other suggestions?
Thanks

Its the 2nd word dude, so change to
# external sd card
dev_mount sdcard_ext /mnt/sdcard
# internal eMMC
dev_mount sdcard /mnt/sdcard-ext

It's not flawless. When mounted by usb to the computer, the phone crashes and restarts :/

---

Well, even though it works it is indeed not flawless.
In my case it works just fine when I mount the Atrix as mass storage, but the problem I've been having is sudden reboots and worst of all, yesterday it reverted back to its original settings all by itself after one of the many reboots.
Too bad since I'm running out of space!
I'll try it again today.
Cheers

I could, after several restarts XD But the problem still persist if I reconnect the usb. So it's an annoyance. Are you on an atrix also?

I have tried this hack and mount both partitions as mass storage without any reboot problem.
The thing is that it seems like it confuses the OS and reboots at random times which eventually causes both mount partitions to fail or even to revert the hack to it's original settings.
I noticed that while the hack is applied, under Webtop the partition labels are mixed up, in other words, what used to be the internal SDCARD after the hack it acts as SDCARD-EXT but under webtop the label remains MB580 which supposedly is internal SDCARD and SD/MMC Drive belongs to what supposedly is now an internal SDCARD.
I hope I made my point on that paragraph!
@roflestomp, by any chance have you partitioned your external sdcard with Webtop2SD? I have and I'm thinking that could be the problem. I will experiment getting rid of the 4GB ext partition I created there and see what happens.
Cheers and happy new year to all!

In red, I think the os is confused (is this what you're trying to say?) and the phone autoreboots but the it doesn't clear my settings to the defaults.
I totally don't understand your paragraph xD Are you saying that some part of the webtop is in the original sd scard (on the atrix system)? If it is, i'm fcked
In blue, did you mount it both as sdcard or sdcard-ext? And when you connect the atrix to usb and computer does it reboot by itself?
Thanks

Sorry for the confusion!
This time I'll try to illustrate with screen caps
But first I'll answer your questions:
1. Yes, what I tried to say was that I think that the OS eventually goes nuts and reboots without any apparent reason and once I noticed that the hack reverted to its original settings, all by itself (at least in my case).
2. Check my screen caps to understand what I meant to say. But don't worry, so far Webtop and even Webtop2sd seem to be working just fine with the hack.
3. Yes, I managed to mount both memory partitions onto my PC with the hack applied without any reboot problems.
Okay, here's the screenies:
First, this is how it looks WITHOUT the hack applied.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Android Settings/Storage - Notice the size of each so you can later tell them apart.
Astro File Manager External MicroSD. For easier identification, I created a folder labeled 123-My External MicroSD
Astro File Manager Internal Memory. For easier identification, I created a folder labeled 123-My Internal SD
This is under Webtop, notice the labels and folder names
Next this is how it looks WITH the hack applied.
Android Settings/Storage - The hack seems to be applied correctly! - Notice how volume sizes have been swapped.
Astro File Manager - Notice how the EXTERNAL memory now shows the folder Iabeled INTERNAL, which is correct.
Astro File Manager - Notice how the INTERNAL memory now shows the folder Iabeled EXTERNAL, which is correct.
Now here's where it turns interesting, notice the labels on both internal an external memory and see that the folders now match to their original un-hacked version! It was supposed to be inverted just like Astro File Manager.
I think theres something else we need to tweak or hack for this to work.
I will start over from scratch with both memory partitions formated and clean OS and post my findings.
Have a great 2012!

Not really...
It's hard to tell on normal things like booting up, saving files, using the video camera and such, but the only place i notice a bit of performance decrease is while launching huge games, but that's because I have a Class 4 32GB microsd!
But I'm not doing this to improve performance, but for lack of space on my internal storage.
Cheers!

P.S. Can you guys see the screen caps in my previous post? On my PC I can't see them, but on my Webtop I can!

Yes I can see your screencaps.
@first post of yours above:
I did it like that and on my pc it's both proper (unlike what u have there at the end) but not before encounterring countless reboots xD The chances of not encounterring reboots is like 10% LOL.
I had to use mount in recovery mode (drains battery) to transfer files.
I thought you're going to show me the part where you had both cards as your internal sd... (or did I misunderstood you again?).

1. I also have no restart with atrix + gingermod 2.3.6 bell rom.
2. The only bug that i have it is that now, windows can only read the internal memory at 1st, i have to plug, unplug, than plug it again to read both internal memory and sdcard, it seems that when the atrix try to unplug the cardmemory to give acess to windows explorer, it doesnt work and the cardmemory stays unpluged, only the second time, with the cardmemory alredy unplugged, widows explorer recognizes my sdcard.

I'm on alien build #4 with working webtop .. that should be the problem ;/

Deos anyone know how to fix the problem with sdcard. After doing the scrit editing, the sdcard is not detected by windows anymore, only internal memory.
Rom 2.3.6

You know? I've seen this problem even without this hack and with several ROMs I've tried, and I use the same plug-unplug-plug-unplug-plug fix with random results.
By the way, I've found that using the mass media notification to switch on and off and on again instead of plugging fixes this more often than not.
