Why not try this: http://www.coreprotect.com/core_shield.html ? Basically, to maintain evidence a drive must be "pristine". In other words, the drive cannot be altered in any fashion during examination. CoreSHIELD enables you to actually boot to the device, but any writes destined for the drive are deflected away. **Disclaimer** - I am affiliated with CorePROTECT. I don't typically respond to the list with advertisements, but I figured it was appropriate in this case. -bob. -----Original Message----- From: Steven A.

You would need to use a program that will make a sector by sector copy of the drive and it must also make a copy of the "empty" sections of the disk, since there could be deleted files in those areas. I know that Symantec Ghost has a switch that they refer to as a "forensic mode", but I have heard from some in law enforcement that this still is not sufficient and you must use a special program, such as Encase. Of course, you would want to check with your local law enforcement to see what they require.

Hello to all, I am interested in forensic examinations of hard drives. In the little material I have seen, the authors state that no examination should be made of an original device; that instead a copy should be made and all examinations made to that device. My question is this: If you make a copy of the hard drive, does it copy the sectors that had recently deleted files or does it just mark them as blank in the partition table of the new drive? What if the source is physically damaged? Or do you need a special utility to get the "erased" data? Thanks in advance for the help.
