Hi fellow member,
I have a 2.5" SATA HDD WD scorpio blue 640GB from my old laptop, i tried to buy 2.5" SATA enclosure and use it, but it didnt detect / install driver,etc my HDD as external HDD on my PC. Then i borrow my friend 5" enclosure that can work with DVD and come with power adapter, try it with my HDD it show my HDD with all partitions as external HDD.
my question:
-does 2.5" enclosure different from each another, do i need some specification for my 2.5" Enclosure?
-can i use the 5" enclosure that come with 12v adapter for my 5v 2.5" HDD? or it will damaged my HDD because over electricity?

thanks in advance and sorry english not my native language

Inside the enclosure there is power circuitry that creates and regulates 12v and 5v line. The laptop drive does not use anything but the 5v line so the 12v pin on the connector doesn't connect to anything on the laptop drive but will on a desktop drive.

Different models of hard drive enclosures have a limit on the capacity of hard drives they support. The one you bought may not support a 640GB hard drive, but I can't say for sure since I don't know enclosure make or model.

Latop hard drives are designed to run on a 5v supply, but don't worry. Laptop drives don't have a 12v pin on the power input port. So the connector inside the enclosure can only feed 5v to a laptop drive.

thanks, very clear explanation
 
After reading it back to myself, I maybe could have explained it more clearly, but glad you understood despite that.
Basically, I was trying to say that on a laptop hard drive there's a pin "missing" from it's power input port. It's the 12v pin and it's missing by design.
So there's no way a 5v/12v female molex plug can feed 12v to the drive.
