[Vibrant Q&A, Help & Troubleshooting] upbeat.addict:
im not sure that the sdparted will do anything in my case (and possibly others) because i can see no evidence in /dev/block or /dev/block/vold that the internal sdcard is even mounted, meaning attempting to repartition would be fruitless since no physical volume actually exists for me, atm.

in fact, last night i pulled my external sd and realized it was being mounted as "mmcblk0", the mount point being targeted by the sdparted script (which i never really got to run) but i used parted to confirm my suspicion. the "mmcblk0" was reporting a 2gb drive, not 16. when i pulled the card and "parted mmcblk0" again, the mount point was no gone. i've since pulled the sdcard out permanently to avoid any confusion. now nothing is being listed in the mount points above. in fact, the sd card, when it was in, was listed as 2 mount points. also, under parted "mmcblk0" is listed a loop. not sure if that's help or if this is, but here are some quick commands to check things out with the filesystems as reference (note: my external sd has been pulled):

i'm now looking into the /sys/devices/platform/ directory currently, specifically:

s3c-sdhci.0

s3c-sdhci.1

s3c-sdhci.2

since those appear to be the devices for the sdcard, and also matches the internal/external paths listed in vold.fstab
