Cloning hard disk

My colleague tried to clone a 80G HD with a 250G replacement using clonezilla. After successful booting with the replacement HD, only 80GB were seen. The following steps were carried out to get back extra disk space:

1. fdisk /dev/sda
2. add a new extended partition which will then become /dev/sda3
3. add a new logical parition which will then become /dev/sda5
4. When fdisk -l is run, it show /dev/sda3 and /dev/sda5 are created.
5. format the /dev/sda5 by mkfs.ext3 /dev/sda5 (*note : /dev/sda3 can not be formatted)
6. assign a mount point to the partition /dev/sda5
7. Add the new mount point to fstab

After system reboot, all added new hard disk space can be seen.
