Hi all, I recently purchased a refurbished thunderbolt display and ever since then ive had issues when my seagate firewire drive is plugged into the display. The system gets extremely sluggish. Sometimes timemachine will not complete the backup. It throws an error (if it comes up again i will make sure to post the exact error, i didnt write it down) Ive also had an issue of various native apple apps freezing. For example system preferences freezes as well as finder. The strange part is that when the drive is plugged directly to my early 2011 macbook pro the system runs smooth. Also the moment i unplug the drive from the display the system regains stability almost instantly. I'm running lion 10.7.2 with all updates installed. What gives? Should I demand a refund and try another display or is this a configuration issue.
