Windows: How to Hide/Unhide Hard Disk Partition using Command Prompt

People generally use drive locker to lock or unlock hard drive partition on their systems to protect data from unauthorized access. Use of software for this task is quite tricky when you forget password because in general life it is difficult to manage passwords from your laptop to ATM. 

So to get rid of this problem we can suggest you to use this method using which you can hide or unhide hard disk partition your windows laptops without use of any software.






















So let's start diskpart prompt to do our task. For this open Command Prompt, it will be much better when you open "CMD" as an administrator.


Now, on cmd prompt type "Diskpart". After few seconds you will be prompted to "Diskpart" prompt.


Type "List Vol" so that you can see all the volumes or drives attached to your PCs as shown in the above figure. Using this command you can find the particular drive information like it's volume number, letters associated with it, labels (if any), file system type, size, status and info.

Now select the dive letter which you want to remove as:

DISKPART>  list vol
DISKPART> select vol 4

Finally remove the letter associated with this drive.

DISKPART> remve letter E 

When you press enter you will get a message : Diskpart successfully removed the drive letter or mount point. After completion of this step your selected drive will be no longer visible to you and no doubt others.


To gain access to this partition again you need to follow the same steps but in place of remove letter you need to enter assign letter. So lets look into this method:


To bring back or unhide partition , select volume which you want to unhide and assign letter to the selected volume. In some cases when you release a particular letter windows automatically assign it to others,  so first check whether the letter which you are going to assign is not in use, otherwise you can assign any other letter.

DISKPART>  list vol
DISKPART>  select vol 4
DISKPART> assign letter E 

After the completion of this step you can see the particular volume. For more tech stuff stay connected on G+, Facebook, Twitter.

Lyrics: Gulabi Aankhein Jo Teri Dekhi Md.Rafi

Gulabi Aankhein Jo Teri Dekhi (Md.Rafi)
Movie/Album: The Train (1970)
Music By: R. D. Burman
Lyrics By: Anand Bakshi
Performed By: Mohammed Rafi


Gulaabi Aankhen Jo Teri Dekhi
Sharaabi Yeh Dil Ho Gaya
Sambhaalo Mujhko O Mere Yaaron
Sambhalna Mushkil Ho Gaya

Dil Mein Mere Khwaab Tere
Bas Tere Jaise Ho Deewaar Pe
Tujhpe Fida Main Kyoon Hua
Aata Hai Gussa Mujhe Pyaar Pe
Main Lut Gaya Maanke Dil Ka Kaha
Main Kahin Tha Na Raha

Kya Kahoon Main Dilruba
Pura Yeh Jaadu Teri Aankhon Ka
Yeh Mera Kaatil Ho Gaya
Gulaabi Aankhen Jo Teri Dekhi
Sharaabi Yeh Dil Ho Gaya

Maine Sada Chaaha Yehi
Daaman Bacha Loon Haseenon Se Main
Teri Kasam Khwaabon Mein Bhi
Bachta Fida Naazneenon Se Main
Tauba Magar Mil Gayi Tujhse Nazar
Mil Gaya Dard-E-Jigar

Sun Zara O Bekhabar
Zara Sa Haske Jo Dekha Tune
Main Tera Bismil Ho Gaya
Gulaabi Aankhen Jo Teri Dekhi
Sharaabi Yeh Dil Ho Gaya
Sambhaalo Mujhko O Mere Yaaron
Sambhalna Mushkil Ho Gaya

---------------------------------------------------------------------------------

गुलाबी आँखें, जो तेरी देखी, शराबी ये दिल हो गया
सम्भालो मुझको, ओ मेरे यारों, सम्भलना मुश्किल हो गया

दिल में मेरे, ख़्वाब तेरे, तस्वीरें जैसे हों दीवार पे
तुझपे फ़िदा, मैं क्यूँ हुआ, आता है गुस्सा मुझे प्यार पे
मैं लुट गया, मान के दिल का कहा
मैं कहीं का ना रहा, क्या कहूँ मैं दिलरुबा
बुरा ये जादू तेरी आँखों का, ये मेरा क़ातिल हो गया
गुलाबी आँखें जो तेरी देखी...

मैंने सदा, चाहा यही, दामन बचा लूं हसीनों से मैं
तेरी क़सम, ख़्वाबों में भी, बचता फिरा नाज़नीनों से मैं
तौबा मगर, मिल गई तुझसे नज़र
मिल गया दर्द-ए-जिगर, सुन ज़रा ओ बेख़बर
ज़रा सा हँस के, जो देखा तूने, मैं तेरा बिस्मिल हो गया
गुलाबी आँखें जो तेरी देखी......

between them. Set the queue size and vary the bandwidth and find the
number of packets dropped.

2. Simulate a four node point-to-point network with the links connected as
follows:
n0 – n2, n1 – n2 and n2 – n3. Apply TCP agent between n0-n3 and UDP
between n1-n3. Apply relevant applications over TCP and UDP agents
changing the parameter and determine the number of packets sent by
TCP / UDP.

3. Simulate the different types of Internet traffic such as FTP and TELNET
over a network and analyze the throughput.

4. Simulate the transmission of ping messages over a network topology
consisting of 6 nodes and find the number of packets dropped due to
congestion.

5. Simulate an Ethernet LAN using n nodes (6-10), change error rate and
data rate and compare throughput.


6. Simulate an Ethernet LAN using n nodes and set multiple traffic nodes
and determine collision across different nodes.

7. Simulate an Ethernet LAN using n nodes and set multiple traffic nodes
and plot congestion window for different source / destination.

8. Simulate simple ESS and with transmitting nodes in wire-less LAN by
simulation and determine the performance with respect to transmission
of packets.

Implement the following in C/C++:
1. Write a program for error detecting code using CRC-CCITT (16- bits).

2. Write a program for frame sorting technique used in buffers.

3. Write a program for distance vector algorithm to find suitable path for
transmission.

4. Using TCP/IP sockets, write a client – server program to make the client
