Is my PSU dead?

Some power supplies can be damaged turning them on, twicksisted suggestion, if there is no load on it. At least connect an old hard drive.

He was already able to power-up the supply using the motherboard.

Geeze, where did you guys learn your diagnostic steps? *Big Grin

Lost data from hard drive, what to do now?

Well, I'm sorry to hear that it's a WD My Passport that failed on you, @tomhenry ! *Frown
I'd recommend you to try using a different USB cable with it and see if that will help your system to detect it without it disconnecting.
I'd also suggest you to go to Disk Management and see how the drive is listed there. It won't hurt to check up on the health and SMART status of the HDD by running the QUICK and EXTENDED tests from the WD's Data LifeGuard Diagnostics. Here's a link to the available software: http://products.wdc.com/support/kb.ashx?id=11ZOpD
