I am running a pair of WD2002FAEX on a Asus P8Z68 motherboard in Raid 1 configuration. Randomly one of the drives will disappear (not seen in Windows, the BIOS or the RAID configuration utility). Generally a couple reboots and it will come up again. Have tried different ports and cables, but am also seeing the same behavoir from these drives in at least 2 other machines running on different model ASUS motherboards.
WD Diagnostics show the disk as fine, but wondering if maybe there is a firmware update available for them? Your help is appreciated. Thanks!
