I have a new XPS laptop running Win7.  When I ordered from Dell I also ordered a 3.0-usb  2TB Iomega external HDD.  The XPS has two 3.0 ports.

I can write to and /copy/move/delete/edit etc files on/from the Iomega.  I cannot use the Search function - it always comes back with "no items match your serarch".  If I plut the Iomega into a 2.0 USB port, it finds files, but only those dated since I received and connected the XPS and the Iomega.  It does not find any of my files created before that in a search.  I can still write/copy/move/delete/open etc on the Iomega

My other external flash drives and my "old" 2.0 external hard drive work with the search function just fine.

I spent almost 2 hours with "online chat" at Iomega and the tech rep could not figure out the problem.  He gave me a reference number and the toll free phone number to call Iomega for free "live" support.  The tech person suggested that I check dell.com for "chip set driver" updates for the ports.  I tried looking for those updates at dell.com myselft, but can't tell which one(s) I should try.

My next option would be to call Dell directly but won't have the time for a few days.  Perhaps I can get a response here sooner.
