Towards the end of last year I decided to remove the CD drive on my late-2007 MacBook and replace it with a 2nd hard drive (using an aftermarket 'caddy').
Several months in, my 1 TB WD Blue (2nd) hard drive refused to open some files so I did a surface scan. This revealed the horror within! Hundreds of bad blocks, so I recovered as much data as I could and put the drive to one side. I replaced it with a different 1 TB Samsung drive. Last week the exact same problem has happened so I have removed the caddy and fitted the CD drive back in.
Is there something I have missed or does it look like the caddy is killing hard drives? It's either that or I have had major bad luck with hard drives.
Is there something I have done wrong? Or is it my laptop that is on its last legs? (this would worry me more). How can I tell?
Sorry if this sounds vague, but I'm quite worried. Please let me know if you need more information.
