Reply: (edit)just use dd. "info dd" for help. Of course, the two will need to be identical. if you have different physical geometries use cpio piped into another cpio.

Reply: (edit)the unix command "dd" will do it, from a formatted disk to a formatted disk. run the dd man page for your flavor of unix, but it would be something like
#dd if=/dev/hda1 of=/dev/hdb1 bs=1024 this will copy from device /dev/hda1 to device hdb1 1024 bytes at a time. You need to find out how your disks are laid out, and use the device that is linked to the entire disk. dd is a raw file copy command (every thing is a file in unix, including the disk and disk partitions) that copies everything without any processing unless you specify processing (such as converting ibm format to ascii or some such). e-mail me if you need more information.

Reply: (edit)I am a novice with UNIX, but have a good understanding of DOS. I have an SCO Unix 3.2 server I need to copy. I want to use a larger hard drive and copy both the OS and all existing software to it. I want to start with an unformatted drive.
I will put the larger hard drive in another computer and practice with some of the programs that will be copied. I considered using Norton's Ghost, but it will not see UNIX and wants to do a sector by sector copy, using identical drives.... unacceptable.
Thanks

Reply: (edit)I have a similar problem. I have network stations that use a compact flash instead of a hard disk. You install a dos formatted CF and set up the station to load & copy the OS from a net server. The problem is the server is miles away and over frame it takes about 4 hours to load the 96Meg flash. I need a way to clone with a laptop using a PCMCIA to CF adapter preferably with win95 or
boot the laptop with a unix boot diskette ( if such exists ) I don't know unix...
Ghost will see the dos CF card when I first boot but if I remove & reistall, it does not see it anymore.
