Hi

Imagine source disk is cxtxdx and destination disk is cytydy

(use "ioscan -fnC disk" to get your disk path)

#dd if=/dev/dsk/cxtxdx of=/dev/dsk/cytydy bs=1024k

This is the command I use, and it will work.

Hi,

Before you do this copy to rely on as a backup mechanisme you could also first test if the source disk is able to read all sectors.

dd if=/dev/dsk/c0t0d0 of=/dev/null

Very fast and will test your disk's readability.
