There is a space in there.  A copy and paste would have worked as well.
df <space> -TH

That is a shame.  Even Windows has an ext2/3 driver.

Here is a clue as to what is going on.  Above and below it is saying
that it is getting a permission denied on the filesystem.

A "sudo -R <yourusername> /path/to/mounted/drive
- From looking at your output, the mount point is:
/media/PPA1.2/

It is possible, you just need to do a little work to make it happen.

I have a really low opinion of Macs, but this is not the time and place
