Hi
If you want to copy the content (data) of a disk to another disk I think cpio is the best . Use dd only if your disk are exact the same and you want an exact copy, block by block.

Hi,

Use cpio
Be in the source directory and issue

find . -depth -print | cpio -pdlmuv /destination_dir

-print option shows you the files on screen during restoration

This is the best method and doesn't give any problems. dd can be used but with the same type of disks,,,,or else it may give problems.
