Recently purchased a Dell Optiplex 9020 off of craigslist. Met at the guy's apt and his wife and kid was there. Dude had an IT career and knew what he was doing. Still, I'm never fully trusting.
The computer has a fresh install of Windows 7 on a 128 SSD. It also has two 500GB HDDs that are RAID 1 mirrored. The OS is licensed and registered. He even gave me key/image on a Dell flash drive for Windows 10. Dude claims this was an office computer and they rotate every 3-5 years (pretty common).
Question is, should I zero all of the drives just to be safe? I've never reformatted or zeroed an SSD and HDSentinal says its at an estimated 80% health so I don't want to decrease it's health even more.
What do you guys think I should do?
