    I'm doing a assignement for University. I've had 2 weeks to do it. It's about terms used for HDDs (e.g. Capacity, Heads, Cylinders, etc.) And I got the first 5 done all well and good. Then it got to the part where I have to explain what "Precompensation" (or "Precomp") is and I have absolutely no idea what it means. I checked Wikipedia, nothing. I Googled it, got websites that gave 1 1/2 paragraphs of nothing and ending with "it is a irrelevant method in this day and age, so there's no point explaining it." I NEED to find out what it is so I can finish my paper! Can you guys and girls help me out please? :(

    That's what I actually found and it didn't provide the suffice information I needed. There's no depth or detail to it.

    My goodness, the course you're taking needs to be updated from the days of MFM/RLL disks! :eek: :p

    It's not that my course is old, it's the fact that I got to do a history on some things and point out the differences and improvements from older technology to newer technology. As for all those website links, like I said before, have a great lack of information. As for someone trying to point out all the crap about densities, there needs to be more information than that so not only I can understand it, but also half the people around the world who may have to look it up. What I needed to know is why the compensation was made, (If you're going to say "it's cause of the changing densities as the head moves from the outer tracks to the inner tracks" then you have no idea what I'm really asking.) why it was phased out, why it was implemented in the first place and how it works exactly (as in, has a lot of details as to what it does and changes).

    Seems to me that's what you're supposed to provide in a term assignment, not have it researched, thought out and written by us. :rolleyes:

    Maybe school's changed since I was in. I know it was hard to erase on the stone tablet. :D

    I'm asking to have information provided. A little more accurate than the change on densities and the time old saying "It's irrelevant these days so we're gonna give you sweet F*** all information." So far, Lurker is the only one who actually sumbitted something that I could actually use, and I thank you for it.

    Normally the process of "research" is actually going out and finding the information. ;)

    Oh really? Well I did research and got nothing. So I thought I'd ask here and all I got so far is a hip of smart *** comments. It wasn't until Lurker helped me out greatly that I'm able to resubmit that last part on the assignment.

    And if I didn't do any research on this assignment at all, I'd be asking what Capacity, Cylinders, Heads, Sectors and a whole bunch of other stuff is as well.

    :rolleyes:
