Got this from a personal weather station mailing list where the tread was about using Raspberry Pi's and 1-wire sensors.<div><br>As for problems with SD cards, I had one that needed to be reformatted after losing power so hearing about other people having similar problems and the idea of moving the OS to a USB drive is interesting -- to bad the Pi doesn't have enough USB ports.</div>

The following allows you to move the entire OS over to a USB drive or flashdrive, both of which are much more sturdy. You still need an SD card in your raspberry, but it is only read, not written to. You can even lock the SD card to prevent writing. I did this with a 32GB Corsair voyager 3.0 yesterday, and it has been running fine as well as faster -- USB flash drive writes and reads go about twice as fast as an SD card. When I get to it, I will try doing the same with a small external drive.</div>
