Convert a FAT or FAT32 Drive to NTFS

hi all,

To convert a volume to NTFS from the command prompt

1.

Open Command Prompt. Click Start, point to All Programs, point to Accessories, and then click Command Prompt.
2.

In the command prompt window, type: convert drive_letter: /fs:ntfs

For example, typing convert D: /fs:ntfs would format drive D: with the ntfs format. You can convert FAT or FAT32 volumes to NTFS with this command.

Important Once you convert a drive or partition to NTFS, you cannot simply convert it back to FAT or FAT32. You will need to reformat the drive or partition which will erase all data, including programs and personal files, on the partition.

this will ask for the drive label... like my drive label is software when m trying to convert d drive.. remaining is self understood..

if this asks for dismount just type y


NOTE: Although the chance of corruption or data loss during the conversion from FAT to NTFS is minimal, it is best to perform a full backup of the data on the drive that it is to be converted prior to executing the convert command. It is also recommended to verify the integrity of the backup before proceeding, as well as to run RDISK and update the emergency repair disk (ERD).

To find out more information about Convert.exe

1.

After completing Setup, click Start, click Run, type cmd, and then press ENTER.
2.

In the command window, type help convert and then press ENTER. Information about converting FAT volumes to NTFS is made available as shown below.

Terms

File Allocation Table (FAT)
A file system used by MS-DOS and other Windows-based operating systems to organize and manage files. The file allocation table (FAT) is a data structure that Windows creates when you format a volume by using the FAT or FAT32 file systems. Windows stores information about each file in the FAT so that it can retrieve the file later.

FAT32
A derivative of the file allocation table (FAT) file system. FAT32 supports smaller cluster sizes and larger volumes than FAT, which results in more efficient space allocation on FAT32 volumes.

NTFS File System
An advanced file system that provides performance, security, reliability, and advanced features that are not found in any version of FAT. For example, NTFS guarantees volume consistency by using standard transaction logging and recovery techniques. If a system fails, NTFS uses its log file and checkpoint information to restore the consistency of the file system. In Windows 2000 and Windows XP, NTFS also provides advanced features such as file and folder permissions, encryption, disk quotas, and compression.

FM on mobile....not really...

Why...why would someone argue that he can get FM going on his mobile phone...all he needs is some software installation. Technical facts apart, why would mobile manufacturers like Motorola and Nokia be so stupid that they won't supply their mobiles pre-loaded with such software.

Just for the sake of arguments, not one, not two but actually three people have argued with me that they can make it possible. All of them students of Communication Engg and one among toppers of the courses Digital Communication and Mobile Communication(I just scraped through!!).

Now, lets get technical and talk facts:
1. Frequency range of public FM broadcasting:87.5 Mhz to 108Mhz
2. Typical frequency region mobiles work at 900Mhz/1.8Ghz(Thats what my mobile says)

Now, simple communication engg principles scream in your face that you need "TWO DIFFERENT TYPES OF RECEIVERs" to receive both. Besides, both are just not compatible with each other.

I am ready to bet a million dollars that a software doesn't exist(can't be made) that would solve this problem(if you call this one).

So next time if you feel like listening to legendary Himesh Reshamiyya on your mobile phone make sure it supports FM radio. If it doesn't, don't install software, just throw your phone away and get a new one that actually supports FM radio.

Dedicated to all the self proclaimed engineers in the field of Communication....

"Hacking"

Hacking, is an art, in that, it needs common sense and you be able to think liberally. Just as japanese fighting techniques teach you,"You must be able to see underneath he underneath". Your eyes should spot a problem as fast as a p4 pc can add 2 and 2. A good hacker must know about hardware. Just learning multiple languages is not enough, play with them, spin your imagination, write codes by yourself, find flaws, think and act smart. Hacking is not cracking that harms someone.. yes some people think its negative part only.. but, Hacking is not a product its a process thats keeps evolving. so! keep learning... and plz dont say it as law breaking kind of thing..

"-just think once more and you will find the solution"

Google : The beautiful mind

Hi all,

have u tried google image labeler..

http://images.google.com/imagelabeler/

it is very simple and interesting also..

the
main thing is that google has started it like a game and ultimately the
image search of google will be more efficient as the images are labeled
acc. to user choices and ofcourse some great algos to determine a
label for an image.

According to the google

Google Image Labeler,
a new feature of Google Image Search that allows you to label random
images to help improve the quality of Google's image search results.

How does it work?

You'll
be randomly paired with a partner who's online and using the feature.
Over a two-minute period, you and your partner will be shown the same
set of images and asked to provide as many labels as possible to
describe each image you see. When your label matches your partner's
label, you'll earn points depending on how specific your label is.
You'll be shown more images until time runs out. After time expires,
you can explore the images you've seen and the websites where those
images were found. And we'll show you the points you've earned
throughout the session.

What is required to participate?

Just
an interest in helping Google improve the relevance of image search
results for users like yourself. Although you do not have to log in to
your Google account to help, logging in will allow you to keep track of
your points. You can also choose to provide a nickname, or you can
remain anonymous.

Hack or Customization

hi everybody,

comin
to the topic.. what u think when u change some system settings tht were
defined by operating system when it was installed.. just cusomization
or a hack?

ok what i think is that if we are using windows which
generally dont allow us to customize; it is called a hack or in case of
linux which is opensource its nothing.. but they provided u the
facility to make that as u wish..

And when we so called hack our windows it looks great that time..

so
i will be posting some interesting posts here.. like changing start
button text and image, changing the boot window, along with some more
hacks..

-enjoy

Get ur computer in speed..

hi all,

today i was answering a question "to increase the speed of the computer.. "

some
users suggested to increase the ram and some suggested to remove
unnecessary processes... But that is not the perfect solution.. becoz
one program one theme one virus can still make ur computer to run at
slower speed which ultimately suxxxxx...

So what shud be done..

upgrading the ram is a solution but why more ram is needed

  • if u play big games on ur computer then u must upgrade...
  • if u are using a theme just remove this.. or if u really want it then upgrade ram
  • if u run large applications then upgrade..
  • if u dont want to handle the things in detail then upgrade..

But this is not wise solution.. so

Stop unnecessary services; but how..

for more details go here http://www.ss64.com/ntsyntax/services.html

learn which services u shud keep runnig

Remove themes and use classic themes..

go to system properties by win+pause/break or right click on the mycomputer icon and select properties..

then
move to advance tab then in performance select settings then in visual
effects select custom and then unselect allthe options in window.. u
can leave second last and third last options. press ok..

Actually u shud read them also.. so that u will know that what u are closing..

pressing ok will take few seconds and then u will be in classic theme.

this will increase ur speed.

Keep Defragmenting ur computer once in two months

right
click on the drive and select properties.. from tools select defrag
option and then defrag all the drives make sure that the drive is 15%
empty as it says..

Use a better antivirus

Nod32 is a really nice antivirus and it updates daily frequently

it is better than anyother becoz..

it
is free for 30 days and reinstalling after 30 days it can be reused it
will not say like other softwares that it is expired and u have to
register it

from norton pt of view.. it is faster than norton and doesnt slow down the computer like mcfee or avast or sometimes avg.

Use a better firewall

like zone firewall

or like outpost firewall

Be Updated with autopatcher

autopatcher
is a really nice software pack that updates windows, it updates mainly
security updates are like they donot let viruses enter in comp easily
in absence of an antivirus for a while..

Remove Startup programs

open run dialog box and type msconfig

then in start up section keep only antivirus program remove all other programs..

Also there are some registry tweaks to make faster shudown and startup

i will be covering that part in the next section of the blog

till then enjoy

A very nice trick of java..

We dont know how to create a program for ping like networking tool..
but we know that windows uses it.. and its own it... So its a trick to
use any service/tool of the windows or any operating system..

Java
Runtime can execute any tool for us.. and we can get input stream and
output stream of that tool.. so I think if u are a java programmar; u
got my poin..

here is an example of this..

DefaultListModel model = new DefaultListModel();
Runtime r = Runtime.getRuntime();
try {
InputStream i = r.exec("tasklist /v").getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(i));

String str = br.readLine();
while(br.readLine()!=null){
model.addElement(str);
str = br.readLine();
}
} catch (IOException ex) {
ex.printStackTrace();
}

this shows a complete list of running tasks on our computer...

so
if we know a specific tool that is used for desired purpose like
ping... use ping to be run and get input stream and then u have created
a program like ipscanner or a ping utility for any platform...

also i think that the same concept can be used in any language..

enjoy the tricks

hi friends,

Do you know what is boot.ini?

If you know then its very fine but in case u dont know..

Assuming u r running a windows XP machine...

press win+r it will open run dialog box... type cmd

ok here is ur command prompt..

type => cd \

now u are in the top level of the directory and where ur boot.ini will be

type => attrib -r -s -h boot.ini

type => notepad boot.ini

it will be like

[boot loader]

timeout=10

default= multi(0)disk(0)rdisk(0)partition(1)\WINDOWS

[operating systems]

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn /bootlogo

this has the information of kernel to be started when computer starts.. timeout in case u have multiple kernels..

u can change it but be carefull

[boot loader]

timeout=10

default= multi(0)disk(0)rdisk(0)partition(1)\WINDOWS

[operating systems]

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Volant -Hacked Boot Window" /fastdetect /NoExecute=OptIn /bootlogo

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn /bootlogo

Like here i have added one line which will show the "Volant -Hacked ...."

although
this will boot the same kernel but will show options to select one of
the two within the time of timeout.. u can addmany more.. its up to ur
choice...

this is the simple basic abt boot.ini or say intro of boot.ini to the newbies..

later i will post a hack that will change ur boot window also..

enjoy..
