The first thing is to buy a drive that has the greatest warranty. There are a lot of cheap HD's on the market that are the pits and have virtually no warranty. For servers I buy drives with a 5 year warranty. ~ A little extra spent can save a lot of headaches in the future.
Since this is a server that you are adding the drive to You might have SCSI drives already installed in the box along with a SCSI controller.
After you have determined what is already installed on the system, get a compatable drive that matches the cpu. A number of the newer drives that have huge capacities have a tough time being read by some older CPU's
When you install the drive partition the drive with either fdisk or cfdisk. I have found cfdisk is a little easier to use for the new user.
After the drive is partitioned you need to determine what filesystem you want to use on the partitions. I prefer ext3 while others prefer reiserfs. With Linux you have a lot of choices. With a home directory I like to manually set the options with the following command:
mke2fs -c -b 1024 -i 1024 -j -m 1 /dev/sdb1 -c Check for bad blocks -b Block size the default is 4096 -i Inode size -j Create a journal -m percentage reserved for lost+found directory default is 5% With gigs of space 5% is a bit much. /dev/sdb1 SCSI Drive /dev/hdb1 IDE Drive
After you have created the filesystems, you should edit /etc/fstab to reflect the new mount points.
Another item is to copy the old partitions to the new partitions using a temporary mount point for the new partitions.
mount /dev/sdb1 /mnt/tmp cp -a /home/* /mnt/tmp umount /mnt/tmp umount /home mount /dev/sdb1 /home
I hope that this helps :-)
