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->=B5SD adapter, you can also use a micro-SD card. The adapter then provides the write protection slider. The mentioned advantages still apply. :-) --=20 Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
