Re: Primary hard drive failure?
Comparing a car to a PC is like comparing human years to dog years.
Data backup will put less strain on a dying HDD (assuming it is dying) than cloning the WHOLE drive. Just imagine the read/write head(s) thrashing back and forward across a heavily fragmented drive (another assumption).
The important thing at the moment is to get your data backed up. Once that has been done and you have 2 copies of it, then you can look at what options you have for either a replacement or repair.
