That kind of surge protection is not absolute.
You're not safe.
An external backup drive, disconnected when not in usage, is a good idea.
The ATX power supply, can fail, and deliver +15V on the +12V rail.
That can damage all the hard drives at the same time. That would be
another example of a fault, but in that case, no lightning was involved.
(It's basically a failure in the regulation inside the supply. That
power supply you bought for $29.95, could fail that way.)
Again, an external backup drive, powered by its own AC adapter, is your
best bet. All the drives inside the computer case could be ruined,
but your backup copy is still safe.
Some people keep a backup drive in the deposit box at the bank, but
that's carrying things to extremes :-)
