new hdd for laptop

In Saturday I buyed the new hard disk (WD2500BEVE) for my laptop (HP xt6200)
The new disk is not initialized by default, so:
– I plugged this unit via USB (Transcend 2,5′ IDE HDD Enclosure for USB 2.0 Port)
– rebooted
– opened the Control Panel\Administration\Disk Management
– initialized the disk
– created the main active partion (100Gb), new logical drive and formatted (NTFS)
– created additional partion (rest 150Gb), two new logical drives (75Gb+75Gb) and formatted each (NTFS)
