Enable or Disable Disk Write Protection in Windows  

I tried to download it without making a donation, but the link doesn't work. I'll try again later, not I'm at work. Thank you.

Yes, link for standard version is broken. I managed to find it elsewhere, but unfortunately couldn't unlock the USB. I had to replace it to the customer and send it to the Provider for a repair or replacement. Thank you for your help.

That's what I was afraid of. A dead USB drive.

I suspect some malware messing with the device flags (USB device type, etc). Isn't there any utility to reset the device flags back to normal? That could fix a lot of broken USB devices.

I had tried the clean command, didn't work. Thanks.

I would like to report that the third option does not seem to work for me. The first fix found on this site did, though: The Disk Is Write-Protected error for Removable Disks

Thank you for your replies, nothing I tried seemed to work, so I returned it for replacement under Warranty.
