Changing partition in Terminal

[loong25]

I have two partitions in my drive, namely System and Data. I wanted to change from loong$ to Data.

Using terminal, I did a mount. Saw the volume Data.

But when I did a cd, error. Anybody can help?

You need a space after the 'cd' command. So:

cd /Volumes/Data
