The hard disk in my laptop Aspire V3-571G is faulty as I keep receiving error messaging warning me that my HDD is faulty and might fail anytime. Moreover the computer has really slowed down and for example takes like 20 mins to start up. I want to backup this current hard disk, buy a new hard disk and swap it. My question is, can I use the back up on this old hard disk to a new one. I find it quite unfair if I have to end up purchasing the software too just cos my hardware spoiled. I am using windows 7 professional. Please advice.
