no SD card .

Hi, I hate to open up an old thread, but does anyone know if this works with the newer nightly builds? I'm having what seems to be the exact same problem... Also, when I go to settings > storage, it doesn't register the card there, and the mount sd card option is blanked out. I'm guessing that that's cause of the emmc thing, but shouldn't it register the extra storage space in the settings somewhere? at the moment, it looks like 16gb has just disappeared...

Also, I'd liketo change these permissions from the phone, using terminal emulator, if that's possible... But your steps don't seem to work for that one.

I am not seeing that behavior at all. Are you sure it is not a problem with your SD card?

are you sure you flashed from a froyo 2.2 build. I flashed from 2.2.1 a while back when I first flashed CM7 and I had the same issues with my external SD, not sure if this is still a pre-req but all the instructions still say to flash from 2.2 when first going to CM7. see link below: I also had scrambled video when booting CM7 coming from 2.2.1 so that is another indication something is wrong, just make sure you follow the steps to a T and know that flashing from 2.2.1 froyo is not the same as flashing from 2.2 froyo

anyways, this could also be an issue that you just aren't sure where to look coming from a samsung rom to CM7. To view your external in CM7 you have to open file manager (astro or whatever you use) hit the home button (file manager route), click the emmc folder and it should be your external SD card. In samsung roms it's in the external_sd folder off the internal SD card.

when I mount my drives via computer both drives come up and they are both read/write so not sure what the guy a couple posts up was talking about, could have been an early bug or something not sure, anyways works fine in the latest nightly so i'm happy

i'm having the same issue.
EMMC not seen by non root explorers
the only way to acces the emmc is by using a root explorer...

LE: found a fix:

External SD card will get mounted as /mnt/emmc. This may not be visible to all apps. If you desperately need the contents visible to apps only looking in /mnt/sdcard, create an empty directory there and remount the /mnt/emmc there as well:

Using either the terminal emulator or adb shell:

su
mkdir -p /mnt/sdcard/external_sd
mount /dev/block/vold/179:9 /mnt/sdcard/external_sd

Note: This is only a temporary fix for when needed. It will cause issues when you try to use USB sharing later. Write the following to get things back to normal:

umount /mnt/sdcard/external_sd

no /sdcard/external_sd

Just flashed to cyanogenmod7.1 found the same problem on my sgs2. ESFileExplorer shows the directory /sdcard/external_sd but it's empty (when I know it isn't).

If you go to settings > cyanogenmod settings > application the is a tick box "use internal storage"

Reboot, all files that were on the ext_sd are now mounted in /sdcard.

Haven't found a way of distinguishing which files are actually on the ext_sd and which are on the internal sd but they are all there.

cyanogen 7.1?

I got a sgs2 and tried everything described above but still no sd card, its just not mounted according to astro file explorer.
I think this sux, cyanogen claims to be the best bla bla bla, but it cant even find/mount a simple sd card........whatever, im going back to my lightning rom. it atleast sees everything i got on my phone

Peace
