Granted it was harder to spot back then but in today’s world of right click format or using a disk utility app you can check it’s the right disk by logically unmounting it first then zap it.
That said, I’ve accidentally deleted the running IOS of a remote switch, luckily I was able to replace it with a copy and it came back after a power cut a few weeks later, i’ve also deleted, replaced and reloaded a switch with the wrong updated IOS, luckily the switch was in the lab so tedious xmodem later it was all sorted, IOS for a 3560 on a 3650 or something easy to miss when doing 3 things at once.
Biting the hand that feeds IT
