A:
I bought mine in store. It works fine on a USB 2.0 port on my computer. I haven't tried with my router, but should be ok, the routers should read it the same as if a computer were reading it.
Are you sure your drive is SATA? My old HP has a PATA drive, in which case this would not work.
Either way, just bring your drive in to the store and have an employee pull this enclosure out of the box and try it with your drive.
