Okay, it looks like it's doing what it's supposed to be doing for the most part. You are getting both drives detected, the bash prompt is appearing. and the commands are executing as expected.

However, there are two problems I see. Here is problem one:

Abnormal player termination
Player received SIGINT, user interruption

I don't think it's supposed to exit the player with an error like that. I could be wrong.

EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended

This indicates there is something wrong with the file systems. You have ignored the text in that FAQ entry telling you exactly what to do if you get an E2FSCK error message. Please follow those instructions, then repeat the procedure and see if your playlists come back after that.
