Software developers, employing the very valid concept of information hiding, go through great pains to hide details from higher layers, such as where the head of your hard drive is reading/writing information from/to. Why do you want to try to "divine" this at some application level with not much chance of success across applications?
More advice: no matter what app or OS you use, make sure there's no compiz or other 3D effects enabled. Keep it simple. (although it all works fine on my KDE 4.5.5 and native effects)
Also switch vid drivers, xorg vesa usually works for this.
I'd use a live CD, getting repositories set up and everything "installed" would still be be quicker than installing to HD first.
Try Mandriva One, suse and fedora. (32 bit might be a good idea too, KISS principle)
I use qt-recordmydesktop on Mandriva, fedora and once on Slax. istanbul is another recording app, it's a bit lighter that RMD, IIRC it has lower frame rates. I've used istanbul on the above and on debian.
I've never had much trouble with any of them, except for a period when the intel drivers were buggy a couple years ago. (fixed with the xorg generic)
I don't go near ubuntu, though I probably should...
Interesting but I can read much faster than you can speak. So I found myself wasting time. Also the video is very inconvenient as a work tool: no way to write notes on it. Once it's gone it's gone.
Also the entire set of experiments could be summarized in one neat table with a suitable comment on how it was done and a few screen shots.
Video is not the best medium for scientific, repeated and lengthy experiments.
This video is misleading to the point of being wrong...
There is no magic here. The inside tracks have no difference in latency to the outside tracks... All that is happening here is that you are confusing track to track seek times with all the other latencies which affect spinning media
@t1nym1ght Sorry about the sound - don't know what happened (but let's blame Windows and call it a day :) ).
I tried using several tools but the one I spend the most time with is recordmydesktop. I just could not get it to work on Ubuntu 8.10 or CentOS 5.5.
I think my next posting, even though I primarily cover storage, is my quest to find a good screencast tool for Linux (one that is easy to use as well). Any suggestions?
@frvfilms Jeff's mainly a server guy, so he had a bunch of trouble getting screen capture software working on his Linux desktop(s). After about three hours of messing around with it he had to call it quits and default to Windows or miss a deadline.
@LinuxMagazine Tell him about Kazam, it works well for Linux desktop capturing. Seriously, I couldn't watch that video cause the Windows recording thing was cutting up his voice.
I cannot figure out how to install Seeker to run the tests? Any suggestions

Buy better hardware ;-)

@ewildgoose Actually what's going on is that you are using less of the disk so the heads don't have to move as much - plain and simple.
However, there is a slight difference in latency between the inside tracks and the outside (despite what the vendors say). It's small but it's there.

The audio is awful, weird noises constantly intermixed with the normal voice.
BTW what Linux are you using? I have never had problems with screen capture, either stills or recording operations...
