Yes, I don't see the drive at all (it has two partitions).
I've also since looked using Mini Tool Power Data Recovery and it also finds no drive. I'll have to look at the manufacturer's website for some kind diagnostic software to check it.
I think I'm going to go back to XP and wait for a good few months before trying Win8 again in the hope that this quite common crash type (going on half a day's forum searching) will have been fixed by then.
You're using XP on a SSD and updating to Win 8? Did you realign the partitions first? Was trim set up from a third party software as XP doesn't support it. You'll need to set up the SSD to work with XP. Once sorted you should have no problems as Windows 8 will take over. As for hibernation you should disable it on an SSD. The more programs you install the more huge the hibernate folder gets. Filling your SSD to a point it will crash.
Once you're back to Win 8 disable hibernate, bottom left corner, right click the start icon and select Command Prompt (Admin), type in ‘powercfg -h off’ without quotes. That will disable hibernation.
OK. I might get my knuckles rapped for this but it might be an idea. You'll obviously know what bit version your OS is and the Windows 8 UPGRADE IS THE SAME. So try this, download the Windows 7 iso from here. (same bit version).
Burn to disk and install on your SSD. Don't attempt to put a key in as you haven't got one. You'll be on a time trial. Now install the Win8 upgrade from within 7. Worth a try.
PS if it's a small SSD the 1st partition should be for win 8 (100mb). If you don't mean that one then you should leave it as a single partition. Even a 120GB SSD is just right for OS and a few programs with hibernation disabled.
