Hello, I seem to have fowled up my backup system on my external hd. I had some trouble so I erased my external hd and attemted to start over using the Retrospect Express software that came with the hd. I mounted the disk on my desktop{the icon shows up on my window}. Now, the backup system scans my internal hd and then says"No removable media found. Removable cartridge such as Zip,Jaz, SuperDisk.DVD-RAM or MO must be mounted on the desktop to be used with Retrospect Express." What am I doing wrong? I have an e-Mac using OS 10.4.2. Thanks Wilton
