Hard drive not detected by Windows

MichaelJ120 · ‎03-26-2022

Hello.

My problem is that Windows does not recognize a third hard drive I am attempting to install in my computer running Windows 10 Pro on an HP Z420 machine. I have two hard drives currently installed and am trying to install a third. The problem is that Windows does not recognize the third drive in either devise manager or disk manager. However, the third drive is recognized in the HP BIOS. I rearranged cables and SATA ports and can get the third drive recognized by windows when plugged into the SATA port originally connecting the second drive. I have tried several fixes compiled from the web but all have been a failure in either they do not work or the steps that you need to follow are not included in my version of Win 10 (built 19043, upgraded to 21H1). HP literature advises that the desktop can support up to 10 SATA devises.

Any thoughts and help would be appreciated. Thanks.

have you tried, all available sata ports

may be stupid, since you say that it is recognized in the bios,
some sata ports are not just disabled in the bios?
