Symantec Ghost was not presented as a means of getting a forensic duplicate. As stated in my first response, the Ghost image is to be added to the new drive and that drive is placed in the suspect desktop so that it can be placed back into production. That would leave the suspect drive available for any type of forensic investigation, whether it is done internally or sent out to another company. I normally do not want to leave a user without a desktop just because I need to investigate something. Since this is a case of data deletion/recovery and not an investigation of suspected torjan/rootkit, getting the system back into production using a Ghosted drive is (in my opinion) a business-practical course of action.

Ghost will not give you a forensically sound image.   Unless something
changes recently, Ghost won't image unallocated space, so you won't be able
to recover any deleted files.   I'd recommend using the Helix Live CD at
http://www.e-fense.com/helix/, which based on Knoppix, but will never automatically mount any disks found, as Knoppix will.

It contains all the tools previously mentioned - dcfldd for imaging, which
you can pipe to netcat to create an image over the network.   The Sleuthkit
for analysis, which is basically just a front-end to other tools also
included.   However, the learning curve can bit a bit steep.

Wow!

Thanks all. I really appreciate the education!

I wish that I could keep the target drive, and change it out. However, this is a Freedom of Information Act issue. I don't think they'll let me keep the original/target.

I knew about Drive Image, but I didn't know it or Symantec Ghost would be able to get the erased data (as in using the "Delete Key" or right click delete).

Thanks!
