SATA HDD adapter works for laptop HDD but not desktop

[relztrah]

I have this clever adapter that I can connect to a laptop SATA hard drive and plug in to a USB port. (See attachment adapter.jpg.) I use this frequently with laptop harddrives to get data off them and I use a laptop hard drive as an external backup.

I connected a desktop hard drive to it but I can't read it. (See attachment connected.jpg.) I get a message "unable to open" and Windows 10 is detecting it as a USB drive. Is this because I need a separate power source that connects to the pins on the hard drive? (See attachment pins.jpg.)

Hi,

I think those adapters can't provide enough power for the 3.5" drives! to support that you must have one with two USB cables or a similar adapter that accept an external power source.

To reach USB3 speed probably only works with extra power...

Thank you. I'll get one that will work with a desktop SATA hard drive.
