Image compression in EnCase and what it really means

May 30, 2012 Leave a comment

It’s often said in the digital forensics world that a RAW image can be seen as more “reliable” as other image types, such as the EnCase .E01 format. The reasons usually given include:

  • The RAW Image Format is basically a bit-for-bit copy of the RAW data of either the disk or the volume, without any additions or deletions.
  • The RAW Image Format was originally used by dd, but is supported by most of the computer forensics applications.
  • The RAW image is uncompressed.

It is true that an EnCase image can be smaller than the actual drive size, or by comparison, to an image taken of the same drive in RAW format. There is no data loss, however; the reason why EnCase can give a smaller image is because it by default it compresses the image to save space. All data in each bit of the original drive still exists. And, EnCase also stores metadata, which isn’t something a RAW image includes by default (although there are cases where metadata can be stored in secondary files).

I performed an experiment on a 150 GB drive, where I first created a RAW image in HELIX (same resulting file size of 150 GB), then an EnCase image which was compressed down to about 60 GB by default. Then, I acquired the image again in EnCase, unchecking all compression options. The second EnCase image was 150 GB. Bit for bit, it was a mirror copy of the HELIXΒ  RAW image, only with inclusion of the metadata.

I’m sure this is old hat to a lot of forensics folks out there, but for the newbies starting out, it’s a pretty handy concept to know πŸ™‚

So much relaxation, plus a cute bunny being petted. Perfect video for sleepytimes. May induce ASMR plus some snoring πŸ˜‰

Book review: A Dance with Dragons (possible spoilers)

May 29, 2012 4 comments

A Dance with Dragons (A Song of Ice and Fire, #5)A Dance with Dragons by George R.R. Martin

My rating: 4 of 5 stars

Excellent book. I need to know what happens to certain folks though, and that won’t be answered until the next one is finished. Argh!

A few questions:

  • Who did Brienne have with her?
  • What happened to Jon?
  • Do Rhaegal and Viserion rejoin Dany or is Drogon her last dragon baby to survive?

Some of the chapters are harder to get through. In usual Martin fashion, there are very vivid descriptions of murders of all types, bowel movements, crazy food (would you eat eel pie?), and of course, forced sex. That’s not to say that those subjects make up the entire series, but it does get old after a while.

This particular title clocks in at almost 900 pages. Well worth it, though.

I often am on the receiving end of these, but that’s part of the business of being assistants to cats:

I mostly annoy him, but he always comes back for more.

She wants a treat. Not just any treat. Chicken!

Mad Men – behind the scenes (The Other Woman)

If you haven’t seen last night’s episode yet, don’t watch. If you have, then proceed πŸ™‚

A few observations:

  • I thought Roger was supposed to be taking care of Joan and the baby financially? It sucks that she had to consent to the date. But, in all fairness, she did get a partnership out of it. Plus, the guy looked like he had to pay for it anyway, so everyone got what they wanted.
  • Joan’s look at Don as she walks into the room said it all… “Don’t judge me, I got what I wanted”.
  • In viewing the above behind the scenes video, Elisabeth Moss (Peggy) describes how she didn’t expect Jon Hamm (Don) to hold onto her hand for so long. Her tears were true. Even before I knew that I was getting teary eyed too. Yes, I did, I’m not ashamed of the tears! πŸ˜›
  • Megan didn’t go into too much detail about what happened at the audition, but by the looks of things, the guys conducting it wanted her to do things she wasn’t comfortable doing. In other words, she wasn’t there for her acting chops, as much as she wants to believe she’s a great actress.

All in all, it was a great episode.
