The EZ-UP-Universal kit from Apricorn lets you upgrade your notebook's SATA or PATA hard drive then use the old drive as an external storage device in three easy steps. Or if you already have an extra 2.5" drive just install it in the case and go. Either way you now have convenient external storage device. The EZ Gig II software can create a clone of your drive for disaster recovery or upgrade purposes. Or you use it to make periodic backups of your system.
