I have a 27-inch late 2009 iMac i7 running Mavericks. Just bought a Drobo 5D. Finder can't see the device with a Thunderbolt cable, but it can with a USB. When looking at the System Information, I see the message "No Thunderbolt driver loaded."
How do I resolve this?
Thanx!
iMac (27-inch Late 2009), OS X Mavericks (10.9.1)
Hi Talarspeed,
Your iMac has a mini-displayport socket, not Thunderbolt, but both use the same physical socket. Thunderbolt sockets on a Mac have a lightning-bolt symbol next to them. The symbol for a mini-displayport is a square with two vertical lines either side.
You can plug a mini-displayport monitor into a Thunderbolt socket and it will work, but you can't plug a Thunderbolt device into a mini-displayport.
QuickTimeKirk is correct about 2011 being the year that Thunderbolt technology was launched. See this Wikipedia page for more info:

Thunderbolt connections were not introduced until 2011. Your machine doesn't have it.
Well that is odd - there is a physical port for it on the back of my machine. And the spec sheet for my purchase says there is one.
HI, I am using G-RAID Thunderbolt 8TB drive. Need to activate thunderbolt port. Need help.
Thunderbolt drivers not loaded on iMac
