USB corrupts?

żIs it possible for a USB port to corrupt flash memory (or even hard disks)?

I think it is possible. I just don't know how likely it is unless you have an infected system.

Thank you, SCANNERMAN777. I'll check the system from a repair CD. However, I'd like to have more opinions.

Do not even forget to check your USB for malware,adware or other issues.I have seed this prob. and It mostly happens by Virused USB.And in this case it's possible that an USB cause errors even crushes.

Years ago, viruses were passed from PC to PC via floppy disks. I once had a virus and when I got rid of it, I began checking my floppy disks. That dang virus was on 50 of my floppies.

Today we can have the same problem with USB drives. (also called Flash Drives, or Pen Drives).

Several of the best AV and AS programs will check USB drives for malware, if you have the drive plugged into a USB Port when the scan is run.

I have one USB drive that contains all my Utilities and I use it on many of my customer's PC's. So I do scan it often for malware.

Cheers mates!

If your USB port is putting out too much or too little power, it could corrupt your flash memory; or it could cause physical damage to the device that is plugged into it.

What is your reason for suspecting that there is a problem with the USB port?

If you use your PC's USB port to deliver power supply to experimental electronic circuits (such as single board computer projects), then you are immediately at risk of damaging the PCs USB port.

USB devices should draw no more than 500 mA (0.5 A) from a USB 2 port or 900 mA (0.9A) from a USB 3 power delivery port.

As far as I am aware, the USB specification does not include circuit protection against over-voltage or short circuits, etc. Far safer to use an independent power supply if you intend to power experimental electronic curcuits.

This is why it is prudent to use a designated USB port that is used strictly for charging purposes and nothing else. I've killed a few sticks in my day failing this policy.
