Could be bad compression, with a bad head this problem gets worse with higher temperatures. Hard starting at hot could be a failing ignition coil, does the engine miss under load at hot? It could also be a failed fuel pressure accumulator or fuel check valve. Scrooch under car, find the fuel accumulator ahead of rear wheels on passenger side. Next to the fuel pump (the noisy unit humming along during operation) there is a can with 2 lines going into it. It's smaller than a soup can. If the car has high miles I would just replace the accumulator as it will probably have failed in the 28year old car. If replacing the accumulator doesn't help, replace the check valve on the fuel pump.

What is hot swap hard drive?

A "hot swap" hard drive is a hard drive you can unplug and plug back in to a computer that is still up and running. With 99% of computer hardware you have to shut down the computer, remove all the power, etc, and THEN you can start taking things out. "Hot-swap" lets you do exactly that. Swap hard drives when the machine is "hot" or powered on.
