Bag of Tricks
Years ago, when memory was measured in megabytes, floppy disks were actually floppy, and cell phones were just for talking I worked as a PC technician. Fast forward a couple of decades and I don't know as much as I used to. I still help friends and family out from time to time. Tonight I got such a call and my initial thought was that the hard drive had failed. In years past I had MS-DOS on a floppy and could run SCANDISK or get to a command line.
It dawned on me, embarrassingly, that I don't have anything to do with.
