do not worry, at least I will not complain.

Should be done in a few hours.

SMART works directly with the drive. Just install it on the memory
stick and run it.

No dust. If dust would be the problem, you would have a very serious
problem. It is either a loose connection or a damaged cable if it is a
problem like this at all.

Connectors are normally able to seal gasses locally of. So, dust cannot
creep in at all.

Even this could be a thermal problem which in turn could be caused
by dust on the wrong place or a dying fan.

Collecting and typing. There are some sample available at the Internet.
In addition I always kept my own entries. I never check if they got
outdated.

A connection to 127.0.0.1 will always be honoured while a connection to
any other address might will result in a time-out which would make
websites slow.
