Popped my old SATA drive out of the ancient machine I hadn't had the heart to disassemble and get rid of yet. Attached it to a little SATA-to-USB cable thing. I'm (slowly) copying many-years-old files off it that I no longer really remember. I'll dig deeper later, I'm sure there will be some interesting stuff.
But for the moment... WOW! I remember when hard drives made that noise!
