My Tab is a Disco10,
I did some searching and found this fix through the terminal Emulator:
\system\bin\fsck_msdos -y \dev\block\vold\179:17. than reboot.
It worked. I'm still going to install a bigger tf card in it,prob a 16gb.
I already have Tim rom 6a downloaded just incase any problems accur.
Hope you had a great Christmas and have a great new year.
