Quote: "What happened?"
Nothing about short circuiting, more a design build flaw where the port on the case came loose, not a problem usually... [Ironically this happened with a cheap USB3 case I bought recently for a 2.5" drive, thankfully they refunded me, it was a Silverstone case... they never have enough counter pressure above the USB port which meant it will wiggle free]
But WD drives use a special mounting method which means that drive will ONLY mount on their drive chip... the chip board inside the case...
Trying to mount it using another connector or sticking the drive directly to a computer internally does not work as you have to mount the drive which would have killed the MBR, all this happened before I fully understood how to fiddle with those things as well, also the drive was fully encrypted... so there was no chance of recovery even after mounting the drive as the files would have no identity from which to recover them...
There was an option which they wanted me to pay their partner company a fixed £300-500 [Cannot remember how much exactly] fee to possibly recover the data... but as I did not want a third party accessing my personal files [Scans of all my banking records etc.] I was happy to just take the hit and format the drive so I can house it in another caddy [2TB drive mind you]
I lost some precious photos, like the time I lived in Japan with my Japanese GF... but they shall remain in my mind for now
Sigh...
Don't get me wrong WD HDD's are great, just never buying an external case ever again unless I buy an aftermarket or whatever case and stick my own drives in it, they do not have fishy mounting systems, as I always shift some drives around from case to case or system and they work just fine...
You could always test this by removing one from your WD case and see if it mounts in your Desktop... this way you can take the initiative to backup that data, buy a custom case for it and ditch the WD one if you are concerned... depending on how old your case is, they might have removed this in recent years as it was a huge issue when it happened to me...
Mind you if it is a massive Printer port style you should be ok, thinking back it was a micro USB port similar to mobiles not the classic tooth shaped one... which my external adapter has, my newer USB3 cases have the huge printer style USB3 connectors so I will not have the same issue again...
Food for thought I suppose...
