Ive got the 1tb network harddrive which connects through my router. It uses the iomega home storage manager software. When i power it up, it connects and i can access all the files for about a day. Then, it disconnects. The drives still on and running, but no longer found. power down and back up again and ive got my harddrive back for about a day. It's a couple years old and used to work fine, but I'm having real problems solving this issue.
