Something definitely didn't go right there. I suspect you'll need to just flash RA and repartition your card with that. In any case, let's figure out the current state of your card and a2sd setup before doing that. There are a few diagnostic tools included with a2sd. The one that we'll get the most information out of here is a2sd check. Do you have adb installed on your computer? The reason I ask is because the output from a2sd check is very long, and it would be impractical for me to ask you to type any of it out here. With adb, you could open a shell on your computer, then copy and paste the output. It will also work with quicksshd running on your phone, and an ssh client on your computer. If you don't have any of that set up, or you simply don't know what it even means, we can do something else that will work just as well. If you *do* have adb installed, do this:
adb shell
su
a2sd check
Paste the output in a reply, here. If you don't have adb set up, run this from the terminal emulator on the phone:
su
a2sd check > /sdcard/a2sd_check.out
That will put a file on your sdcard called a2sd_check.out, which will contain the entire output of the file. Copy that file to your computer, then either attach it here, or just open it, and copy and paste the contents. Once that is done, we can take it from there.
