One of two hard drives (WDC model WD6400AAKS-75A7B0 ) configured as RAID1 failed. I replaced the failed drive with WDC model WD10EALX, which I was told by WDC can replace the original model, which is no longer available. After installation, the computer indicates "missing drive".
Note that after starting the computer, the computer spent a long time searching for a driver. Is there a way to find the appropriate driver and install it manually? Or, is there another way to handle this problem?
