SD Card removed without ejecting... data destroyed. BACKUP!
Just a warning to others that twice now I've lost ALL the data on my SD card by removing it from my computer without first ejecting it (once by mistake and once where the computer lost connection to it). Im not sure if the problem is with the card, my card reader or the computer but I've not lost data like this from other types of drives when accidentally removing before ejecting.
Obviously you should never remove any drive from your computer without ejecting it first, but accidents happen. Just a warning to backup as much as possible so you don't lose your work like me.
Lesson learnt and shared :-)
