Hard drives forensic examiners tackle may be as little as 20
gigabytes, or some newer drives are 250 gigabytes, even up to
750 gigabytes.

Computer forensic examiners, using special computer forensic
software, first acquire an image of the target media, then do an
analysis.

A lot of the evidence you seek will not be visible to the untrained eye. You won’t find it in a Word document by using Windows Explorer, or by starting a program from a shortcut on the desktop.

| How much data can be found on a hard drive? |
 |
Hard drives forensic examiners tackle may be 100 gigabytes, and some newer drives coming out are 500 gigabytes, even 750 gigabytes. To give you an idea of how much data a hard drive could hold:
- One gigabyte of information equals 6 million pages of doubles-spaced typed text
- 12 gigabytes of information equals 1,200 cases of laser printer paper.
Looking from smaller to larger digital measurements:
- 1 byte is a single character (number, letter, punctuation mark, etc.)
- 1 kilobyte is a paragraph
- 1 megabyte is a small paperback novel
- 100 megabytes is three feet of shelved books
- 1 gigabyte is more than 60 feet of shelved books
- 100 gigabytes is a university library!
In all that space on a hard drive, there must be evidence somewhere!!!
