Some USB devices may use special drivers to try to get optimum performance
out of the device. I don't know if LaCie is one of these. Many other devices
use the drivers supplied by the O/S and work fine.
I have a Maxtor external drive that will not work with Windows 98. Yet I can
use my 500 gig drive (installed in a case made by Adaptec) on Windows 98
just fine. This is one of the reasons I highly recommend Adaptec products.
They just work!
Check with the drive manufacturer to see if your external drive needs these
special drivers. Then get the Vista drivers you need.
