 One costly mistake many companies make is to image and
entire hard drive of a server, computer or laptop, sends it
to a vender and say, “process these files”. That means
identify all the files on the hard drive, load a database with
information about the file and make the files and data
searchable for litigation. This is often a waste of money if
you include all system file and program files if they are not
relevant to your case.
