After partitioning and formatting a new drive, you must mount the drive. To mount a new drive, you must have a mount point, know the drive's file system type, and know the drive's device name.

# mkdir /mnt/zipext2
Use the mount command, and specify the type of file system using the -t option, the device name, and the mount point:
# mount -t ext2 /dev/sda4 /mnt/zipext2
Use the df command to verify that the new drive has been mounted:
# df File system 1024-blocks Used Available Capacity Mounted on /dev/hda6 1443464 1011187 357689 74% / /dev/sda4 95167 13 90240 0% /mnt/zipext2 ...
