|It's very common for data to get damaged on a flash drive such that it doesn't show up in My Computer or Windows Explorer. |
Make sure the problem isn't with the pen drive.
Try the pen drive with another computer or computers.

"My laptop usb port damaged due to lightning"
The power surge or voltage spike caused by a lightning strike can damage anything, even if you had your computer's AC adapter plugged into something that protects against power surges and spikes, and the voltage spikes can be a high enough voltage that they can even jump across switches that are switched off.
If you're plugging it directly into a USB port built into the case, there's probably nothing you can do about your problem,
- unless - the USB port is built into a small board inside the laptop, like I've seen on the few (PC laptops) I've seen the insides of, that plugs into the mboard, in which case you could try replacing that board. In that case, if you're fortunate, it's likely at least one of your USB ports built into the case works fine, at least one other one doesn't.
If all your USB ports built iinto the case do that, only replacing the mboard will fix your problem.
For those small boards I've seen, they had two USB ports built into the same board the jack for the AC adapter is in, and there was at least one other USB port elsewhere on the mboard.
