What kind of problems might be caused is hard to say in the first
place, but knowing brands and model designations would certainly
increase your chances of getting a good answer.

But most laptops, and probably a lot of desktops, do regulate down
their input power from the AC adapter, so there's a good chance that
being 20% over the nominal input voltage won't be an issue for
short-term use. It's may generate more waste heat, though, which could
reduce the long-term life of the product.

It's highly unlikely that if there are just file-system errors alone
that these are due to the power supply. Typically you'd see other
errors as well or instead. But I suppose it's not impossible that the
drive is seeing voltages slightly out of its spec that cause it to be
dodgy even thought other parts handle things ok.
