In Shimla, a dodgy internet cafe virus wiped my SD card, and I lost all the photos from Nainital, Haridwar, Mussoorie and Dehradun that were on it. The ones I was most upset about losing were the ones from my day in Dehradun and the two couchsurfers I’d met.
When I got back to the UK, I used Recuva to recover the data from the SD card. Some of the photos were immediately recoverable in perfect condition, while others were corrupted to differing degrees: some were completely destroyed, while others had bits and pieces still salvageable.
