Thanks Ubrales! I was the victim of a hard drive failure a few years ago after hearing clicking noises. It's not fun loosing all your data... Now I always do backups and run two drives in raid 1.
Excellent! That's exactly what I have and what I do - two Seagate 1 TB HDDs in RAID1 dedicated for data, and I backup the entire system every month.
My laptop HDD started clicking sounds, and very quickly I cloned the HDD and upgraded the capacity at the same time using Apricorn's hardware and software. "EZ UPgrade" for the laptop, and "Drivewire" for the desktop.
