Hi everybody.

My N900 is with custom kernel, over-clocked, a bunch of apps (incl. RobbieThe1st - latest ver - i think its 0.62-1) and it was working fine, till today. When i was cropping the picture on the phone, it restarted.

Few hours before that I fsck-ed all partitions with "RobbieThe1st" and they were OK. After crash, I checked them again and on "Checking the OptFS..." it gave me this prompt:

"Errors may have been encountered: code:4 /dev/mmcblk0p2: UNEXPECTED INCONSISTENCY;
RUN fsck MANUALLY (i.e., without -a or -p options)"

I think this is /home path, so many things on the phone are not working (obviously )

I tried to fsck on tablet, but I cant unmount /home.
I was googling whole day, but just cant find a solution.

Now here comes the question:
How can I fsck /mmcblk0p2 via terminal on OSX?
I am a noob, so please explain in details

A big thanks to one with an answer and I hope I would not need to reflash N900 again.
