Windows 7: Uninitialized USB drive is "Write Protected"?!

Uninitialized USB drive is "Write Protected"?!

Sis' picked up a "My Passport" [WD] 2TB (USB) for backups on her HP lappy (Windows 7 Home Premium).

Obv. one has to format it... but that's easier said than done as the drive is "write protected" according to the "Disk Management" utility.

I've googled for an hour, finding no solution, and:
  • Uninstalling the driver had no effect
  • Adding a "HKLM...StorageDevicePolicies[WriteProtect=0]" entry had no effect -- supposedly a Vista fix that would work on Windows 7 according to several posts
Nearly all hits I found were for folks having issues with formatted drives with data that suddenly became write-protected: I didn't see anything in them relevant to my problem.

I'd appreciate any help. I'm 1K miles from home and have no other computer to initialize it (other than her Macbook or iMac!) nor am I clear how to run installation-disk functions where they are embedded on an engineering partition (not available on a CD/DVD).

Thanks... John
