I have a Z640 with Thunderbolt. I have connected two G-Technology G-Speed external drives in a Thunderbolt daisy chain. The computer shows both drives however is only allowing one to be active. There is an error code 12 on the inactive drive which states "This device cannot find enough free resources that it can use." G-Tech states its a Thunderbolt port issue. Another user thought it might be the BIOS. Thoughts? I'm sure I can't be the only one with more than one Thunderbolt external device connected.
