The dock looks to be the right part but you'll have to tell more.
My old HP Pavilion dv9207us stopped working and I purchase a new HP Pavilion dv3-2155mx notebook. The old computer will not start up. I pulled out the external hard drive (Western WD 1200BEVS) SATA 2.5" and purchased a Thermaltake BlacX docking station (P/N: ST0005U) to transfer data onto my new notebook. It says it should easily transfer SATA 2.5" and 3.5" hard drives. I am cannot connect my hard drive to it. Do you know why?
