Glad you have data still Conan, can only make you more cautious in future.
My intention in buying an external HD isn't to rely, indeed I back up stuff onto CDs weekly though my filing system is non-exsistent
Then again, even if I lost most of my files, I'd be annoyed but there's nothing vital in there (150GB of photos is a lot of memories though!)
I keep meaning to sort out the 'important' ones and get them printed for even safer keeper but never get around to it.
