Please consider this question and let me know if I have understood mounting
I have two internal drives sda and sdb. I have the special windows 7 partition on sda1 and windows main on sda2. Debian on sdb2 and linux swap on sdb1.
I also have and external ide/usb drive which holds my personal data. I also have a cowon iAudio7 usb drive. Until now I was not sure how to mount these in a way which would not cause permission problems. Until now I would mount the ide/usb drive manually on each boot to a directory i created called "myhome".
The cowon music player shows a strange fat partition scheme which had me dumbfounded. This meant I reading/writing data to and back from ext3 with the occassional permission problems.
Therefore depending on the connection order the names for the external hard drive and the cowon music player are inter-changable between /dev/hdd to /dev/hdc

Here is cowon partition scheme.

Here is what I have done
I created a directory called myhome and another folder called cowon. I then mount external drive /dev/hdc1 to myhome and the cowon iAudio7 to the folder myhome.
As of this post I don't have the cowon connected: Here is what df gives me:

This doesn't look like a partition table
Probably you selected the wrong device.

Now my external drive mounts automatically without having to mount from the console.? For the iAudio7, I still have to type:
mount cowon
Can you confirm if I have done this correctly? Why can I getaway by specifying /dev/hdd but must specify sdc1 in relation to external drive.
Finally, I understand I can mount the drives holding windows sda1 and sda2 with ntfs file systems exactly the same way. Persumably that means I can read and write to the ntfs file systems. Assuming I am correct what is the difference between this and installing some sort of driver to transact between ext3 and ntfs.???
