I have been using something similar, even though it's not _exactly_
what you're asking for. My "solution" (haha): Get a SD card with
the required capacity and initialize it as intended. Then use the
write protection slider. The card is now write protected. Then get
a USB card drive (usually in the shape of a regular USB stick, for
example a USK SD/MMC/MS-MMC USB 2.0 card drive) and put the card in.
Now you have a write-protected USB drive. :-)

There are two advantages:

a) In case of media failure, just replace the SD card.

b) In case of reader failure, just replace the drive.

Additional fun: If you use a SD->µSD adapter, you can also use a
micro-SD card. The adapter then provides the write protection slider.
The mentioned advantages still apply. :-)
