I connected a 1TB 3.5" HDD with a breakout cable to my notebook. When I start the notebook, the HDD is not spinning up nor is it getting recognized. I toggled the Bios options AHCI on/off and LBA to Dos/other, with no success. Could it be that the sata power connector on notebooks only delivers enough power for 2.5" HDDs?
Technically everything is working fine. Usually I use the notebook with an SSD. A 2.5" HDD connected to the breakout cable works. The 3.5" HDD connected to my desktop PC works. I'm getting a couple of old HDD ready to sell through ebay. Having a 2nd PC to test and delete would be very useful to me.
