if it was so easy...

i had this error the first time I tried (a few hours ago), and decided to skip.
the result was that when it started copying the OS, it all looked OK, but I was not paying attention. Then, it started saying "cannot copy ..., insufficient space on disk" when I looked at the memory usage, mmc2 was completely free, and the device memory had 1kb free.
I presume that the mount failed, but i'm not certain. Is there any way of removing the mount and re-mounting it afterwards.
any clue how?
