I’ve just bought a WD7500BPKX to install it as a secondary HDD in my DELL Precision M4800.
First I tried to put the HDD in a secondary dock instead of the CDROM of my laptop. Then the windows 7 Enterprise 64bit became very slow to start up. And the HDD was not detected in the windows storage management tool.
Then I checked in the BIOS … HDD was not recognized.
Second test, I replaced the main HDD of my laptop by the WD7500BPKX. At the BIOS level … HDD was not recognized.
Third and last test, I put the HDD in a external USB box. I plug it into an USB port of my laptop. And now the HDD is found by windows and seems to work well.
I don’t understand why the HDD is not recognized when it is plugged inside my laptop on a SATA port.
Before sending back the HDD, I ask you if I miss something to make it work fine in my laptop? or if it seems to be a HDD failure?
