I have a Win XP pro PC and a Win 7 Pro PC.

Sometimes when using my SanDisk Ultra USB3 128G flash drive it says it
is write protected.
I do not do this !

Why and how does this happen ?

I cannot figure out how to un-writeprotect it in the Win XP pro PC.

THERE IS NOT MECHANICAL SWITCH on the flash!

But if I put it in the Win 7 Pro PC and do a quick TOOLS/ERROR-CHECKING
check it will take the write protect off and I can then again use it in
Win XP Pro.

How do I do this in Win XP Pro without have to lug my Win 7 Pro desktop
around with me when I travel ?

I have other flash drives and this never happens on them.
Could be the user that made the files on machine A is not the same as
machine B. I have a lot of issues when moving usb hd's around from
machine to machine. I may have done as Good Guy suggested but I don't
have XP, all Win10. So maybe I've skirted the issue that way.
