Thanks to the findings of various commentators, I thought the driver might be different following that diet is SATA or Molex. For SATA, go for the Driver of Transcend Germany (there is no on sites other countries, including the USA). Follow the menus to arrive at the Germain ref TS-PDU3 then load: TS-PDU3 / PDC3 Driver (uPD720202) (with SATA power connector) Vista WinXP Win7 8312.4KB v3.0.23.0 (Does not need to install driver on Win8 ) This driver actually works (for SATA) while V.1.2.5.0 in my view is reserved for the Molex power (at least, with PS at home with SATA, it does not. So Messrs TRANSCEND , review your copy and put your doc to date. Otherwise, thank you to MICMAR that put me on the road. I put three stars only because the hardware is ok, but the doc is below everything.
