I'm using a HP dv4-2160us with 4GB ram, Win 7, 64bit. I purchased two Seagate FreeAgent Go 1TB drives (USB). If I plug in only one it works great. If I plug in both neither show up. I wan't to use both with Adobe Lightroom, one as the catalog and the other as a back up.
I've reinstalled the SW from Seagate, searched the Knowledge DB at Seagate and HP without success. Seagate Tech support was not helpful "sounds like a driver problem .. contact Microsoft".
Anyone else had his problem? Any suggestions?
