Here ...
Nope, I didn't have in mind that it is not doable, it is of cause but the computing if far fore than typing some commands as far as I'm concerned. As you have to split drive it results in meager volumes capacity. As most of office work naturally will be done in Windows and with little time you realize that drive wasn't divided wisely enough. Then, windows doesn't know to read ext3 volumes and if you set some rogue driver and drop/edit some files it then looses attributes in Linux and so on. I can mention LOOooooOooNgggg list of mishaps. If a task is just to try Linux to learn some commands it may be the solution, but if you use the computer as a everyday tool it becomes mind boggling. As you wok in Windows and then you recalled that there's files you need to address had been stored in Linux, and zipped with encryption, or simply drives doesn't work for you, you will be forced to reboot again, and if you run some serious Excel's table for example and in a middle of something ... That what I mean when I say it depends on definition “lot a trouble is”. OS X is free of all this hassle; it also offers ALL of the commercial tools one need to perform a job.
As long as you will have Windows on it you will not be really using Linux, as it is lacking of tools to have job done for everyday life. I mean you can do everything if you are independent completely, but as far as I have to comply with corporative standards, there's no real possibility to employ it is a way it has to be done. The compatibility of peer applications is marginal: just a little bit complex and it renders your job incorrectly. So that it was a reason (among many other) to abandon PC platform. With OS X you have luxury of all commercially available high quality software and it rides over very polished UNIX. It is solid.

Note
This manpage has been automatically generated from fdutils's texinfo documentation. However, this process is only approximative, and some
items, such as cross-references, footnotes and indices are lost in this translation process. Indeed, these items have no appropriate rep-
resentation in the manpage format. Moreover, only the items specific to each command have been translated, and the general information
about fdutils has been dropped in the manpage version. Thus I strongly advise you to use the original texinfo doc.
* To generate a printable copy from the texinfo doc, run the following commands:
./configure; make dvi; dvips fdutils.dvi
* To generate a HTML copy, run:
./configure; make html
A pre-made HTML can be found at: `http://www.tux.org/pub/knaff/fdutils'
* To generate an info copy (browsable using emacs' info mode), run:

The texinfo doc looks most pretty when printed or as HTML. Indeed, in the info version certain examples are difficult to read due to the
quoting conventions used in info.
Description
floppymeter [-f] [-w warmup-delay] [-W window]
[-c cycles] [-h] drive
The floppymeter program measures characteristic parameters of a floppy drive and floppy controller, such as the rotation speed of the
drive, the data transfer rate of the controller, and the resulting raw capacity of a disk track. To use this program, insert a disposable
floppy in the drive, and type floppymeter --density, where density describes the density of the disk used for the test. (Should be one of
dd, hd or ed). CAUTION: the data on the disk will be erased. This program should be used to verify whether the drive and controller are
out of tolerance if you experience problems with some high capacity formats. It only needs to be run once per drive: although a disk is
needed to perform the measurements, the measured data only depend on the drive and the controller, and not on the disk.
To measure the raw capacity of the disk track, the floppymeter program formats the first track of the drive in a special way that allows it
to read the raw data (gaps and headers) of the disk. Thus, all data previously stored on that disk is lost.
The rotation speed is measured by timing the return time of a readid command. In order to gain more precision, the command is issued many
times in a row. During this phase, the number of rotations since the start of the test, the average time per rotation since the start, and
a sliding average of the times of the last 30 rotations is printed, and updated continuously.
The data transfer rate is deduced from the two parameters above.
At the end of the program, all parameters (raw capacity, duration of one rotation, and data transfer rate) are printed again, as well as
their relative deviation to the standard value. Finally, it suggests a capacity deviation description line, which can be directly pasted
into the drive definition file (See section Drive descriptions.).
Usually, the data transfer rate should not deviate more than 150 ppm from the expected value, and the rotation speed of the drive should
not deviate more than 3000 ppm from the expected value. If these deviations are bigger, you may get problems with certain high capacity
formats.
If the raw capacity of the drive is too small, some high capacity formats may become unformattable on this drive/controller combo.
If on the other hand, the raw capacity of the drive is too big, you may get problems when writing to a disk formatted by this drive on
another drive with a smaller raw capacity. In order to avoid this, increase superformats gap parameter (-G).
-h Prints a short help
--dd Tells the program that we use a Double Density disk.
--hd Tells the program that we use a High Density disk.
--ed Tells the program that we use an Extra Density disk.
-f Runs the measurement non interactively. With this option, the program doesn't ask for confirmation, and doesn't display the contin-
uously updated values during the rotation speed measurement.
-W Window
This value describes how many rotations are used for the computation of the sliding average. Default is 30.
-c cycles
Describes the number of rotations clocked during the rotations speed determination test. Default is 1000.
Bugs
This program is quite new, and may have bugs. Here are a few suggested tests to check its sanity:
* The deviation of the data transfer rate solely depends on the controller. It should not be different between two drives connected to
the same controller. However, the drive rotation speed may be different for different drives.
* All data transfer rates (for double, high and extra density) are derived from a same master frequency. Thus the deviation of the
data transfer rate should be independent of the density used.
