USB 3 Flash Write Protects Itself

Many times my USB 3 Flash (SanDisk USB3 32G) drive has decided to go to
write protect while being used on Win XP Pro PC. I cannot figure out
what causes it. I can read all I want but not write a single byte.

I have found that by simply placing the USB 3 Flash drive in a Windows
7 PC is the only way to unlock it. Doing so does no damage to files.
Then it reads and writes just fine in the Win XP Pro PC until it
decides to write protect itself.

Is there not some solution that can be done in just the Win XP Pro PC?
My Win XP PC goes on the road without a Win 7 companion.

Are you sure the USB socket on the Windows XP PC is USB3? On Windows 7,
I had an intermittant problem with my HP laserjet printer causing the
blue screen of death until I switched its USB connection from USB3 to
USB2.

All ports on Win XP are USB2 and I did try several.
I also have Sony USB3 Flash drive that always works fine on that PC and
in all the ports before and after the Sandisk write protects.
The problems seems unique to the SanDisk.

When I plug the SanDisk into my Win 7 PC it pops up a message to scan
it.
But it also locks up the mouse so I have to keyboard fiddle until I get
to the button to do the quick scan. The quick scan reports it found no
problems but then taking it to the Win XP Pro PC it now works properly.
Somehow the scan removes the write protect.
After pulling the SanDisk from the Win 7 PC, the mouse is active and
all else seems OK.
Really weird.

Format it to remove the Sandisk software.

If you don't use the USB3 protection stuff then I'd be wiping the drive
to rid it of that first and then see if it still exibits same problem. I
just did that to a 2Gb Sandisk given to me (it wasn't acting funny but I
didn't give it a chance to) as once I saw the virtual CD drive I knew
what was going on. I had to use the removal tool from their website.
