It assumes adding one PATA (IDE) harddrive as master on the second IDE controller, but the process will be similar in other situations. More on that in step 2.1.
*It assumes adding one PATA (IDE) harddrive as master on the second IDE controller, but the process will be similar in other situations. More on that in step 2.1.
The harddrive will be named bigdisk, this name will not be visible to the user.
*The harddrive will be named newdisk, this name will not be visible to the user.
You already have an ibay named mp3, this will be redirected to the new disk (together with its content). This name may be visible to the user (depending on the permissions).
*You already have an ibay named IBAYNAME, this will be redirected to the new disk (together with its content). This name may be visible to the user (depending on the permissions).
You can replace the names bigdisk and mp3 with whatever valid name, just keep track of the names.

Alternative 2: A much better approach is to leave the second disk mounted at /mnt/bigdisk and to create symlinks (symbolic links) for specific ibays or user folders.
