HDD are frequently corrupted due to power events.

Does anyone have a reference to HDDs getting corrupted by power
events on the mains power supply?

Reference Microsoft

"Because you didn't shut down Windows properly, Scandisk is now trashing
your disk to complete the job.

In future, always shut down Windows properly"

Scandisk is not *always* going to pull your nuts out of the fire after a
power interruption. In fact, it might make things worse

Wouldn't you *expect* data corruption, if the system was writing/about to
write cached data, and the mains power went off?

Not if you have an OS that knows what it's doing. A great part
of file system code is supposed to anticipate such things. For
instance, one approach is to not put the file entry in the user
file directory file until after the last bit is written and the
user's prog has issued a close.


You don't need references to figure out that it's a bad idea to just
lose power in an uncontrolled way.

Of course it's a bad idea :-) but most systems, that went through
a design, allocate quite a bit of their code to Murphy anticipation.
