I'm sorry, I don't understand There's this thing called "mounting" in Linux. Basically, it's a way of letting you access the files on a device or partition by making it seem as if the device or partition is part of the larger filesystem--it appears as a folder.
For example, if I plug in my wife's iPod, the iPod itself is located at /dev/sda1, but I can't just go to the /dev folder and click on sda1 to open it. Ubuntu will automatically create a "mount" point for the iPod and /media/ipod, so if I browse to the /media folder and click on "ipod" the iPod's contents will appear in that folder called "ipod."
Well, actually, I don't even have to browse to the /media folder. External media just shows up on the desktop automatically.
Are you familiar with the Mac term "alias" or the Windows term "shortcut"?
When you have a hard drive installed or a partition on your computer, there has to be a way you get at the files in there. For Linux, that means "mounting" the partition or hard drive as a fake folder. The folder doesn't actually exist. When you go to that folder, it just points to the partition.
Let's say, for example, that your new 250 GB hard drive is located at /dev/hdb1 and is FAT32. You could mount it to be at /extra_drive. Then, if you went to the /extra_drive folder, you'd see the contents of that hard drive.
If this is sounding too complicated, you may want to consider using Mepis. In Mepis, all your partitions and hard drives are automatically on your desktop. You click on them, and they automount and open. It's the same process, you just don't have to create the mount point and edit a configuration file to have it happen.
Did that clear things up or just make you more confused?
