problems mounting external drive

[onetitfemme]

I am trying to mount my external drive. I think it had a FAT32
partition of 80Gb (the whole drive), but I am not able to.
..
The drive may haver had powering problems (low power supply not a
spike).
..
Based on the output to the tried commands, what is happening to it?
..
How can i fix my drive? As I scarcely remember you could use qparted
to solve these kinds of problems, but I don't know about the details.
..
How can you fix the drive using knoppix or any other utility for that
matter?
..
Thank you

Well your error messages are indicating that the drive is not partitioned.

Your drive needs to be repartitioned and formatted to something other than
what it is (MAC OS?)
