Is it absolutely necessary Maria?
I appreciate it's frustrating - I've lost documents before that took me ages to get up & running and had to start from scratch. I know it feels they're lost forever but unless they're very specific, i.e. photos you took for somebody's wedding and cannot be taken again, is it possible to just learn the lesson and start again?
Can any pictures from photo shoots you have done be retaken? If you're honest with people & say you've had a hard drive failure most people would understand & would be happy to have you back again.
I always go a bit OTT back things up 3-4 times as I fear this happening! I hate that dreaded feeling. I hope you manage to get somethign sussed.
