Hey Thanks!

Can I use the copy made by dd for the analysis? Specifically... 1)I want to
go to the site, 2)copy the drive, 3)take the copy made back to my location,
4) restore the data to another drive and mount it to an existing system and
then 5) forensically analyze the restored copy for deleted files.

Can I use your directions to accomplish that?
