Research: Erase Hard Drive/ Thumb Drive





2: Degaussing

Hard drives are nothing more than bottles of data held in place by magnetic glue. By removing the magnetic glue, you can create a breakdown of the underlying bits and bytes and scramble them in a way that's pretty tough to recover from. If the degaussing device used is good enough, you'll destroy all of the bits and bytes at the user level as well as the low-level formatting that makes it function as a drive. (If you're serious about data security, you'll use a powerful degausser.)
Although degaussing might be looked at as a way of simply erasing a drive, it's actually a destructive mechanism, though it's not nearly as fun to watch as a shredder.
Powerful degaussers will also render inoperable a drives servo motors and will damage the spindle motor of the drive. It truly is a paperweight when you're done.
A really good degausser is expensive, but it doesn't cost as much as a really good shredder, and it might be enough for your needs. Also, it's a fast process. Take a look at this YouTube video of a hard drive degausser in action.



Wiki: Degaussing

 

Magnetic data storage media[edit]

Data is stored in the magnetic media, such as hard drives, floppy disks, and magnetic tape, by making very small areas called magnetic domains change their magnetic alignment to be in the direction of an applied magnetic field. This phenomenon occurs in much the same way a compass needle points in the direction of the Earth's magnetic field. Degaussing, commonly called erasure, leaves the domains in random patterns with no preference to orientation, thereby rendering previous data unrecoverable. There are some domains whose magnetic alignment is not randomized after degaussing. The information these domains represent is commonly called magnetic remanence or remanent magnetization. Proper degaussing will ensure there is insufficient magnetic remanence to reconstruct the data.[2]
Erasure via degaussing may be accomplished in two ways: in AC erasure, the medium is degaussed by applying an alternating field that is reduced in amplitude over time from an initial high value (i.e., AC powered); in DC erasure, the medium is saturated by applying a unidirectional field (i.e., DC powered or by employing a permanent magnet). A degausser is a device that can generate a magnetic field for degaussing magnetic storage media.[3]

Irreversible damage to some media types[edit]

Many forms of generic magnetic storage media can be reused after degaussing, including audio reel-to-reel tape, VHS videocassettes, and floppy disks. These older media types are simply a raw medium which are overwritten with fresh new patterns, created by fixed-alignment read/write heads.
For certain forms of computer data storage, however, such as modern hard drives and some tape backup drives, degaussing renders the magnetic media completely unusable and damages the storage system. This is due to the devices having an infinitely variable read/write head positioning mechanism which relies on special servo control data (e.g. Gray Code) that is meant to be permanently embedded into the magnetic media. This servo data is written onto the media a single time at the factory using special-purpose servo writing hardware.
The servo patterns are normally never overwritten by the device for any reason and are used to precisely position the read/write heads over data tracks on the media, to compensate for sudden jarring device movements, thermal expansion, or changes in orientation. Degaussing indiscriminately removes not only the stored data but also the servo control data, and without the servo data the device is no longer able to determine where data is to be read or written on the magnetic medium. The medium must be low-level formatted to become usable again; with modern hard drives, this is generally not possible without manufacturer-specific and often model-specific service equipment.

Darrell's Reading List


Here are some books I've been reading lately:
  • Hacker: The Outlaw Chronicles (here) by Ted Dekker (Author). The story of a young Hacker girl, who went on a wild adventure into the supernatural realm beyond trying to save her mom, but saved her self too in the process.
  • Saint: A Paradise Novel (here) by Ted Dekker (Author). He's an assassin, or is he? He finds a secret to his past that unlocks supernatural abilities, at a cost.
  • For a full list of all my book suggestions, see my Amazon Store.

The W Story Structure - 4 Sequence Story Structure

Out of everything I've ever read on story structure for fiction writing, the W-Story Structure makes the most sense to me. If you'd rather view these as Acts (3-Act or 4-Act) you can overlay that on this W and it still works.



Glen C. Strathy writes (in much more detail here) in his article, The W-Plot vs. The Dramatica Model of Story Structure. There are four sequences for most stories. Each of the four legs of the W is comprised of a sequence of events that lead the story along to it's natural conclusion.

Sequence 1: setting up the problem (creating tension)Sequence 2: recovering from the problem (new ideas, positive momentum)Sequence 3: deepening of the problemSequence 4: the resolution of the problem (new light or understanding)

Sequence 1: setting up the problem (creating tension)
The Inciting Event (the event that is at the heart of the reason this story happened) may have occurred before your story begins, and often does. In King Arthur: Legend of the Sword (2017), th…

Topic: No More Facebook... for 28 days or more?

I Deactivated Facebook... for 28 days.
I'm not sure why yet.
I wasn't using it much, and when I did I found it distracting, in a non-productive way. I left Twitter up for now, and Google+ is so pervasive that I'd have to delete ALL my Google activity/accounts in order to walk away from it.

Deactivating is not the same as Deleting, that would be permanent. I set Facebook to auto-reactivate in 28 days. I want to run this as an experiment. Can I make it 28 days without Facebook? I think so. I may come back. I'm not sure yet.

What could I accomplish in the next 28 days? Write a new book? Publish some new posts? Work overtime at my job? I don't know. I'd like this to be more purposeful.
28 days from Dec 27, 2014Want to figure out the date that is exactly twenty-eight days from Dec 27, 2014 without counting?
Your starting date is December 27, 2014 so that means that 28 days later would be January 24, 2015.
You can check this by using the date difference calculator to meas…

Eradicate the word "had" from your writing.

I have been writing for years, first as a hobbiest with passing intrest, then semi-professionally as a blogger, then professionally as a Complaints Reporter and Letter Writers, and now as Technical Writer working on Policy & Procedure (P&P). In that time, I've had the opportunity to edit other's work even more often than my own.

Had is an easy way to clean up your manuscriptAmong the most common pitfalls I've seen, in both Nonfiction and Fiction writing, is the word "HAD". You can almost always simply delete it, and it the sentence will not only remain fully intact, but the meaning will be clearer.

I notice it in my writing, in my Letter Writers, and I've seen it three times today in other authors at Scribophile. Below are the works I critiqued/edited today.

Both are examples of good storytelling and world building. Both have edit issues to work out to be ready for publishing.

Both are examples of how incomplete craft (my own included) can be overcoming b…

FICO

$ 14  FICO
W hat is a FICO score? Many people want to know what a FICO score is. FICO stands for the Fair Isaac Corporation, founded in 1956 and in 2009 renamed: FICO. This is the one company that has more control over your interest rates and loan approvals than any other. They review your credit reports and create a score based on the information found there.
            The formula that determines that score is TOP SECRET. The banks don't even know it. We do know a few things about the score though.  The Credit Scores can vary from 300 to 850, recently information has come out that it may go into the 900's now. A “Good Score” is hard to determine because different lenders have different cut off marks. According to Wikipedia the average marker in the USA is about 640.[1]This score is about the breaking point between bad and good. Typically, though, banks are looking for scores in the 700’s
~DSR or DTI~             The better your score the better the interest rate and the higher th…
