Thank you for your reply,
I have no option to turn RAID on or off in the Startup Options menus. No selection for AHCI/IDE/RAID.
It would appear that this dual drive is incompatible with my system. Also updated system BIOS to latest version to see if the feature had been added to the menus, which was not the case. GRRR!!!
I have tried enabling the CSM by setting the Startup Options to Legacy and not EFI. (Had to re-install windows 8).
No success in detection. Confirming your diagnosis.
Is there some way that a product return can be authorized in this circumstance? I have just blown $300 on a drive that is not compatible with my system. And as the product is marketed towards end users performing their own upgrades…
One would think that WD would provide (in addition to the lovely video clips of Meghan installing a dual drive)- a system check tool to check for system hardware compatibility - prior to purchase???
