I have an interesting situation. I have a Dell XS23-SB server that has four blades in it. The blades use Supermicro X7DWT motherboards, and interface with the sata drives through a backplane.
I took two identical drives from a raid 0 enclosure that came from the factory (GDrive), one works on all four servers, the other does not. I verified that they both work by plugging them into a hard drive cradle.
This behavior can be repeated with other drives, some drives work and some don't. However when i test them, they ALL work on my PC.
What could cause this?
