clone the second scsi disk
 

Hi all, I had Linux 6.2 with two scsi disks, but only the primary has been installed and used. I think about cloning the primary disk to the second disk. I did dd , but failed while reading the primary disk. Is that any another way to do that?

If you booted to the system and the drive was mounted then yes you will get an error. Try booting to a live-cd and use the dd command withOUT the drives being mounted.
