Nope, label important pieces of your equipment properly so it won't get thrown out accidently. Have your important stuff in some box, case, drawer, ... which your GF/BF is not allowed to touch or whoever messes around in your belongings.
i think he had some drawer he kept things in but that still didn't stop him from looking at the hard drive and saying to himself "i should throw that away i don't need it anymore". what a bonehead thing to do, throwing away a good hard drive. do people really do that? throw away a good piece of computer equipment that is functional because if so then i need their phone number.
You should always have redundant backups. No backups, no mercy!
he didn't think anything on the drive was important thus no need to backup i guess!
You fucked up? Move on, reinvest, don't hopelessly clinge to the past.
i kind of regret more that a perfectly good hard drive was thrown away never to be used again rather than what was on the said hard drive. i hope the gentleman who lost all his bitcoin comes to see things from that perspective too one day.
