Hi, I'm currently experimenting with G4U (Ghost for Unix), a small cloning application sending disk images to an FTP server. The application reads the whole disk bit by bit, compresses it and then stores it remotely. Due to this approach, it's more or less filesystem-independent. The drawback is that it sometimes results in huge image files. Now I'm currently following a hint which suggests to fill the disks' unused space with zero bits. Here's the command for that: # dd if=/dev/zero of=/0bits bs=20M # rm /0bits Now I gave that a shot, but after half an hour or so, I got a bit impatient. Now the computer does not respond any more. Does that mean he's just way too busy with dd? Or is there some mistake in the command? As I see it, it will just be chugging on and on, no? Shouldn't there be a 'count=x' option somewhere? Niki
