I already have multiple HDDs installed and, yesterday, added 3 new WD20EARS to the system. All three appeared to initialize correctly.
-After a reboot, only two of the new drives were recognized. In Disk Manager the third drive is/was listed as "disk not initialized".
-Tried re-initializing the drive multiple times and got a couple of different errors, "incorrect action" (or similar wording). At this point the system crashed.
-After a system restore, the third drive is not visible at all. The other two new drives seem to be operating normally.
System is an i3-540, Gigabyte GA 57M USB3, Ultimate 64.
What should I try?
