QUOTE OF THE DAY

I think Linux is a great thing, in the big picture. It's a great hacker's tool, and it has a lot of potential to become something more......

MAKING DRIVE VISIBLE

As we have seen in the last how to hide the drive.....now we will discuss how to make it again visible?

First Step:

Open command prompt by opening it from start in windows.....after this write diskpart.

Second Step:

After this write list volume....a list of drives available in your computer will appear on the screen...


Third Step:


Now select the drive which you want to make visible...by writing select volume (drive number)...
eg: select volume 4


Fourth Step:

Write... assign letter (drive name).
eg: assign letter E



Fifth Step:


After this your drive is visible again.

HIDING DRIVES THROUGH COMMAND PROMPT

First Step:

Open Command Prompt by going on the start menu and write diskpart.

Second Step:

After that write list volume...List of volumes will appear on the screen...

Third Step:

After this select the volume which you want to hide....by writing select volume (number)...this is the volume number you want to hide.

Fourth Step:

Then write the remove letter (drive Symbol)( suppose it is E:)..so write remove letter E.

Fifth Step:

You will see the drive has been hided.
