In my day to day role as an IT Pro, I have to visit customer sites to perform hardware maintenance. Today is one of those on days for me. I was tasked with replacing a failing HDD within a server located in a customer data centre. In modern servers a failed HDD is not a problem, they are hot swap. Unfortunately this server is nearly 15 years old, runs Windows NT4 Workstation, and the drive is buried deep inside the machine. The only option is to visit site and replace it.
