[sleuthkit-users] RE: Road Machine, Imaging, and Processor Speed?

[Eagle I. S. <in...@ea...>]

I have been toying with the same idea and would love feedback also.

I'm a newbie to Linux, and so far have had horrendous speed issues with
dd. (over 90 minutes to image a 6 gig drive on the same IDE chain). Now
granted
I used a basic command of the form:

dindang:~/test #  dd if=/dev/hda1 of=/root/test/hda1

There may some parameters I don't know that could have helped.

The machine was a 2.0G P4 with 1Gig of Ram, running Suse 8.0.

I'm on my way to buy and Image Masster solo to do imaging, but like Rich,
I'd love to be able to use a laptop for this kind of field work, or even a
custom built
PC, but I haven't had faith in running DD since my 6gig drive experience.

An Image Masster Solo is super-fast. It'll image 40 gigs in less than 15
minutes.

I've seen it and used a loaner unit many many times, and I've been impressed
every time. It has no regard for bad HD or sectors, it also scours the image
drive to DOD specifications before making the copy.
It also has a feature to add a text file with drive info to the image drive
if you
are imaging multiple drives. But, alas, it costs in the region of $1500.

Subject: [sleuthkit-users] Road Machine, Imaging, and Processor Speed?


Hey,

I need to put together a portable imaging kit.
Obviously I will use a laptop (w/ Linux), but question
is on CPU speed.  I realize CPU speed is very
important for my analysis station (searching etc...),
but how important is a faster processor to making a dd
image for take back to the lab?

Budget is limited, but I don't want to shoot myself in
the foot either.  I use a 3.06ghz P4 w/ 1gb ram as my
analysis machine and it hauls butt on everything
(although, I do want to build a dual cpu machine - I
hear they really crank on searching!)  What is
everyone else using for their road machines?

Does anyone have any preferences or experience with
low, mid, and max speed laptops?  Or, for that matter,
any opinions on using an Apple laptop to make dd
images to take back?

I really want to get the best machine possible, stay
within my budget (which I don't have the $$ figure
yet), and be able to get other peripherals.  I will be
using firefly's from digital intel for connecting
suspect and target drives, and will max out ram on
whatever I get.

So, what are your thoughts?

Thanks in advance,
Rich
