OK got around to multi-quote...
Computer is back although dead hard drive is not good. Cannot get any data off it.
Time Machine on my MacBook Pro is wonderful :!:
Automatically backs up every hour whilst it's plugged in.
I hope you did not loose too much important 'stuff' JohnK.
You have an external hard drive to support Time Machine? If not, you mustn't have a lot of stuff (i.e. the size of it, not necessarily how important it is), albeit I hope Time Machine backs it up to another physical disk. No good having your backup on the same physical drive as the one that fails in the first place.
The common failing of most Windows users - not backing up. It's easy to set up, but few do it. On that note, I'm not much better (though I am trying...)
I lost most data I had over the past 5-6 years.

There were many important things in there least of which was photos from my round the world trip with dad in 2009.
Oh well my stupidity. There may well be a way to recover the data but I am not sure if the cost is feasible. Need to do some research on who provides those services.
There are services that can help mete out data from failed hard drives, though it's not necessarily perfect. Indeed, there are some people who do this seriously for a living and can extract parcels of information from seemingly dead-as-doorstep drives, though it's usually not for the data you're looking for unless you did something very, very bad.
The costs are nominally "expensive", but the people who will usually fork out for these services know the recovery is well worth the cost. (This is off-hand advice, not necessarily tailored to your situation). Such services usually charge by the GB or so.
Now that you've had a failure, I should probably check my last generation of backup! I've got a massive collection of photos - some on my main HDD, some on my external HDD; some in only one location, some as multiple copies! Why do I create a mess for myself......
