Mount a different partition to USB Mass Storage

Hi,
I've been wondering if it might me possible to mount a different partition or event better an iso file and make it visible via USB Mass Storage instead of the sdcard?
I had a look around and found the /etc/vold.conf:
Code:
volume_sdcard {
## This is the direct uevent device path to the SD slot on the device
media_path /devices/platform/msm_sdcc.2/mmc_host/mmc1
emu_media_path /devices/platform/goldfish_mmc.0/mmc_host/mmc0
media_type mmc
mount_point /sdcard
ums_path /devices/platform/usb_mass_storage/lun0
}
I tried to change media_path to, for example /dev/block/mtdblock4 but apparently vold didn't like it
Did anyone try to do such a trick? Any tips?
Thanks,
ziggiesandvik

it shows there...
media_path /devices/platform/msm_sdcc.2/mmc_host/mmc1
so it appears to mount the actual memory card. there fore it should mount all partitions available on the memory card.
I know that works, when i plug my phone in on a machine running linux it will mount all my partitions for example ext3 and my fat32.
are you trying to mount an internal partition on the device?

I remember there was something in the ums_enable script of the modded recovery, which echoed the device path to something in /sys/, though I'm too lazy to pull it up now. Changing that device path did let me mount other things (like a loop image on the sdcard) to the USB mass storage.

Yes, that's what I'm trying to achieve - expose a different partition via usb.
I tried to change the media_path to for example /dev/block/mtdblock4 but it didn't work.
I was unable to find anything in /devices/platform/... that would look like a partition.
I'm stuck

how do i get internal storage to show on miui without a sdcard?

how do i get internal storage to show on miui without a sdcard?

What exactly do you mean show?

I believe I may be having same issue so i will explain. My phone after flashing to MIUI cannot jse a sd card I put in for what ever reason when I insert one it gets super hot and just tells me card is ready for removal with no way to mount. Before Rom Manager would allow me to use internal memory for roms or downloads from browser but after miui I cannot even find the internal memory. We just want a way to access it.

Just flashed miui on my G2x and an experiencing the same problem...

If you don't have an SD card and want to make the internal SD act as the external click here and flash the external secondary miui one.

I want to try the MOD you posted but can't download it to phone because of no sdcard problem.

What I did was restore to gingerbread or cm7. (basically a ROM that can discover the internal sd.) Then i connected it to my computer, put the mod and MIUI on my internal SD, wiped data, wiped cache, flashed miui, flashed the mod and bingo

I think I have a solution for you. You will need a file manager with a text editor built in like Root Explorer. Brows to /system/etc and open vold.fstab. This is the file that tells the OS where to mount the storage. Yours is most likely trying to mount the internal on the external sd which is default. All you have to do to change this is to change the vold.fstab from this:
Code:
# Internal SD card
dev_mount emmc /mnt/sdcard/_InternalSD 9 /devices/platform/tegra-sdhci.3/mmc_host/mmc2
# External SD card
dev_mount sdcard /mnt/sdcard auto /devices/platform/tegra-sdhci.2/mmc_host/mmc1
To this:
Code:
# Internal SD card
dev_mount emmc /mnt/sdcard 9 /devices/platform/tegra-sdhci.3/mmc_host/mmc2
# External SD card
dev_mount sdcard /mnt/sdcard/_ExternalSD auto /devices/platform/tegra-sdhci.2/mmc_host/mmc1

[SOLVED] How to use External SD instead of Internal Storage of MSI Enjoy Tablet

Problem:
After Upgrading to 0224 official MSI ROM, you'll have a new issue with the SD card, it means your SD card is totally unusable and all the apps know the internal 4GB memory (in fact about 2GB) as the primary and the only alternative memory of device, so all related data files will be on "storage/Android/data/".
Solution:
With this modification we'll completely switch the Internal Storage of the device (4GB) with your External SD card (up to 32GB) and after this all the data files will be on "External SD/Android/data/"; but the only issue is for the labels, after switching:
4GB Internal Storage as external_sd ("/mnt/extrenal_sd')
(up to)32GB External SD as flash or sdcard ("/mnt/storage")
Requirements:
1- Root access (use Gingerbreak, see here)
2- Root Explorer or any app you can modify the file "/system/etc/vold.fstab" with
3- Overwriting the attached file or simply changing the codes as below and Reboot:
Before:
Code:
dev_mount flash /mnt/storage 1 /devices/virtual/mtd/mtd9/mtdblock9
dev_mount sdcard /mnt/external_sd auto /devices/platform/rk29_sdmmc.0/mmc_host/mmc0
After:
Code:
dev_mount sdcard /mnt/external_sd auto /devices/virtual/mtd/mtd9/mtdblock9
dev_mount flash /mnt/storage 1 /devices/platform/rk29_sdmmc.0/mmc_host/mmc0

talk about persistence...
Many thanks goldie, I will try this out later.

You need to provide more detailed information, as to what error message you are getting. When you install an app from the market what error do you get? And post a screen shot of your Storage(Settings->Storage) page.
Are you able to mount the SD cards on your phone?
Instead of doing all that said above, which I think is in-correct, becuase he has given the same Label name to both cards!.
Copy this to your volds.fstab file:
Code:
## Vold 2.0 Generic fstab
## - San Mehat ([email protected])
##
#######################
## Regular device mount
##
## Format: dev_mount <label> <mount_point> <part> <sysfs_path1...>
## label - Label for the volume
## mount_point - Where the volume will be mounted
## part - Partition # (1 based), or 'auto' for first usable partition.
## <sysfs_path> - List of sysfs paths to source devices
######################
## Example of a standard sdcard mount for the emulator / Dream
# Mounts the first usable partition of the specified device
dev_mount sdcard /storage/sdcard0 [email protected] /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.0/mmc_host
dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.1/mmc_host
dev_mount usbotg /storage/usbotg auto /devices/platform/mt_usb/usb1
## Example of a dual card setup
# dev_mount left_sdcard /mnt/sdcard1 auto /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.0/mmc_host/mmc0
# dev_mount right_sdcard /mnt/sdcard2 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.2/mmc_host/mmc2
## Example of specifying a specific partition for mounts
# dev_mount sdcard /mnt/sdcard 2 /devices/platform/goldfish_mmc.0 /devices/platform/msm_sdcc.2/mmc_host/mmc1
