East St. Louis is a legendary American city, for all the wrong reasons. Those three words conjure up thoughts of extreme poverty, extreme crime, and danger, sometimes perceived, and sometimes very real. It wasn’t always that way, to hear some locals talk.

The IBM PC/AT had a troubled history with hard drives. And if you’re using one today, even if it had one of the better hard drives in it, after 35-40 years it may not work. Here’s what you need to know about IBM 5170 hard drive types to substitute newer drives for it.
The IBM 5170 defined either 14 or 22 different hard drive types, depending on the BIOS revision. You’ll get best results if you choose something that can emulate one of the existing types.
