Mine went about a month ago.
Mostly rare stuff from my raving days that I'd downloaded but is neigh on impossible to find again.
Started using google music to back my stuff up now.
I feel your pain bro. I had some personal stuff on there as well that will be hard to find, like demos from bands I've played with and friend's bands, stuff like that. It's even worse than when I lost some naughty pics of a girlfriend back on that fateful day in '06.
Gonna meet up with a buddy later today though. He knows his way around hardware and says he might be able to recover some or all of it.
