The title pretty much says it all.
Today I learned that hard drive platters used to be made of glass. As an IT guy, I’m tasked with destroying our company’s old hard drives. Typically, I just remove the platters and bend them in half (they’ve always been constructed of plastic platters with a magnetic surface, as far as I knew) - mostly because I like disassembling things. Today, however, I was destroying an older hard drive. When I went to bend the platter in half with one hand, it exploded in glass fragments. I now have a nice, deep 2-inch gash in my hand and shards all over my office.
Thankfuly I was alone today, otherwise this would have been a contribution to the embarassing moments thread…
