Now that you have the new disk installed, the next step is to partition and format t he disk.
Decide how many partitions you want. If you want more that four, my suggestion would
be to make one primary (for part of the disk) and one extended for the rest of the
disk. Them you can make up to 15 logical partitions inside the extended partition.
For this example, let's use two partitions; one for data files and one for music.
Remember, this is just an example.
Use your favorite partitioning tool to make two partitions of equal size to take up the entire disk. Then use the mkfs command to format both partitions.
Now make two mount points to mount the partitions. Something like 'mkdir /mnt/data'
for the data partition, and 'mkdir /mnt/music' for the music partition.
Now to edit /etc/fstab. Make two entries, one for each partition. So, if the new disk
is hdb, and the partitions are hdb1 and hdb2, your entries in fstab would be:
/dev/hdb1 /mnt/data ext2 (mount parameters) 1 2
/dev/hdb2 /mnt/music ext2 (mount paramters) 1 2
where (mount parambers) are like the parameters for other partitions in fstab, and 1 2
(if I remember correctly) refer to boot order.
The partitions should automount on next boot.
