Can each sector only have four words?
sectors will have more that four words, i used 4 words sectors in the example because I got bored of typing 1's and 0's.
the information about locks per cylinder can usually be found written on the hard drive
Over time, will it be like the information was never there? Would you be able to make a guess of how long it would take?
[quote]Five passes is supposably the least number at least that's what the documentation for DBAN says
I was told that all magnetic objects loss their magnetism after some time(a quick example is a natrual piece of magnetic rock would lose it magetivity in about 10 to 15 years depending on how much it was) and that objects can become magnetic themselfs by being introduced to magetivity over time. If what I had been previously told is true, then marking a | and a _ repeatedly would cover up any trace of the one area at one point to have had more magnetivity in one area over another at a certain point in time.
If I get what you're saying then yes that's true... all objects loose magnetivity over time. some quicker than others.
conversely most ferrous metals can gain magnetism as well.and tend to sway to a particular domain. that's why the whole writing/re-writing stuff happens
Do you know why people still make programs that encrypt instead of programs that scrub?
When you said "when you change a 0 to a 0, if it's been a 0 for a long time" did you mean "0 to a 1"?
Is there any writable space on a disk that doesn't have a magnetic | or a _?
cause there is still money to be made, some will say that encryption is better than erasing cause the disk is writen with seemingly random data.
yes, too many ones and zeros!
the | and _ were symbolic (but strangly accurate)
the bits on the disk are arranged either longetudinally or traversly by the read/write head whatever the specific domain of the particle then head reads that and knows it as either a 1 or 0
