Leopard- Quicklook needs my attention!

Everytime that i plug up my xternal hard drive with Leopard, when browsing folders of media files i keep getting the voice prompt :excuse me quicklook needs your attention".

It seems like I get a prompt for every thumbnail that quicklook builds for a video file or picture.

Any way to shut this annoyance off for quicklook????

Well you could shut off the voice altogether but I guess that's not the proper solution. I however have not had this problem even though I frequently plug in an external drive.
