[Q] CWM not recognizing internal SD card

view story

http://forum.xda-developers.com – sorry if this has already been answered-- I tried some googling, but didn't find the exact scenario I'm in Anyways, I finally decided to install a ROM on my GS3 today (have done it in the past with GS1) and the rooting/ installing CWM process went smoothly. However, when I went to install the ROM from recovery, it gave me a "E: Can't mount /sdcard/" message. The phone boots up normally and I can explore the sd card after it boots. I can also launch CWM after the phone boots and choose to install the ROM there-- but when the phone restarts into recovery, I get the same error me (HowTos)
