Default Lightning damage to USB drives?


Anybody know of a USB flash drive being damaged during a typical
electrical storm or whatever other common electricity surge? (I'm not
talking about a lightning strike close enough to destroy the whole
computer.)

I'm wondering about the possibility that a hard drive and a USB flash
drive could be destroyed at the same time, given the flash drive is
always attached to the USB port, and whether that has in fact ever
happened.

Thank you.

It can happen if the lightning strike kills the power
supply and massively over voltages the 5V rail.

It would be safer to put the flash drive on a powered USB hub.

and whether that has in fact ever happened.

Just wondering Rod, how'd you come to that conclusion? More than likely the
usb hub will be plugged into the same electrical source as the PC and
therefore also be effected by the by the power surge. Would it not?

Wall warts have pretty good safety measures.

And computer SMPS dont?

Nope, quite a few of the cheap ones die very spectacularly
indeed, over voltaging what is powered from them.

Transformer based wall warts are much less likely to be
damaged by the sort of lightning damage he was asking about.

Corse the transformer base wall warts do with the sort of lightining
damage that was asked about, just due to the transformer alone.

For the reason I mentioned in the quoting you snipped and I have restored.

Yes.

and therefore also be effected by the by the power surge.


Nope, not when its a simple wall wart plug pack for the powered hub.

Would it not?


Fraid not.

hmm.. I would have thought otherwise. I guess you learn something new every
day.

That makes sense when I think about it... You're saying the SMPS will
essentially blow up and allow unregulated current through where as the
transformer will continue to reduce voltage although not all the way to 5v
it will still probably be in the safe range for the flash drive.

I had a lightning strike near the house and it blew out several things in
four houses total, mine got the worse of it.

However, my computer was on a UPS and the network connection went to a
router then to the modem.

The UPS, cable modem, and router were fried (along with other things in the
house) but the computer itself was unaffected.

So, I doubt a normal electrical storm, etc. would blow out a drive or USB
drive.

Pity about those used without a UPS.
