Earlier quoted context omitted.
Working on the hardware directly is more than half of the fun.
An old IBM tech told me that hard drives failed when power cycling equipment could be temporarily resuscitated by placing the drive on the floor, twisting it hard by hand, then as quickly as possible connecting it back into the machine and powering on. Apparently getting the platters to spin helped them get around a worn out motor that couldn't make the initial spin-up.
As much as I love hardware, I much prefer our current solid state wonderland.
