One of my dog daycare clients dropped their laptop a few months ago, killing the hard drive.
Of course being the unfortunate bastard that knows a thing or two about computers, it landed in my lap. I threw in a spare 320GB HD I had kicking around, in place of the 500GB one that was in there, and installed W10 on the thing. I didn't charge anything because they give us a fair bit of business and I wasn't using the hard drive.
So the laptop lands in my hands again today. "They dropped it and think it needs a new hard drive again" - sure enough, it boots up but can't find the hard drive. Fuck people, take care of your shit.
I proposed they spend 75 bucks and I throw a SSD there instead, because it'll be quicker and hold up better to their dropping-shit habit... but no, they don't want to spend money. So I'm reinstalling Windows again on a 80GB, 5400rpm Fujitsu drive I found. It's gonna be slow, but they've been warned...
