Did you disconnect it without using the safely remove feature?

When you say, it 'won't switch on' do you mean that you are
getting no sign of power at all? Does the drive use an external
power supply or is it powered from the USB cable? The PC
going to sleep shouldn't have anything to do with 'safely remove'
as it wasn't actually removed so I'd start by swapping the USB
cable if you can get hold of one or if it uses an external power
supply then that needs testing.

Then what does this mean? "I have tried
plugging it into various other computers but it
wont work".

I don't know if this device was disconnected when the computer was in hibernation or not but could explain why it isn't showing on other computers. Just one of many possibilities.

if all else fails you could take the drive out of the case and add it as an internal drive, in fact to prove the drive or the external case/power supply is or isnt the issue, try taking it out anyway
and testing internally and maybe try another drive in the external case..

This is all about the need to reinitialize USB HDD. When Windows awake from sleep, it doesn't remember the external HDD being connected. This is due to a long standing design flaw. Just unplug & re-plug it back in for Windows to re-initialize it.

In the future, always safely remove external HDDs and flash drives before Windows goes to sleep.
