Recover pen drive memory space

Have your pen drive memory space been lost? Don't worry. You could recover pen drive memory space easily. Most of the time it happens when you are going to make a bootable pen drive or doing other things. Many people comments us that after making a bootable pen drive they lost their pen drive memory space (from 8GB to 2GB). Please don't take it as a serious issue. It does not hamper your pen drive memory. Actually your USB flash drive (pen drive) memory space divided into two parts, one is allocated memory space and another is unallocated memory space. If you are using Windows operating system then "Disk Management" application will help you to add this unallocated memory space with allocated memory. "How do I recover this unallocated memory space?" Well, you can follow the steps given below.

  • Insert your pen drive to PC.
  • Type "Disk Management" in windows "Search programs and files" from Start menu.
  • In searched programs you could see "Create and format hard disk partitions". Open it.
  • You could see your computer as well as pen drive memory space partition.
  • To combine Primary Partition with Unallocated space, first select Primary Partition. Now click on cross (Delete) button on the above toolbar.
  • Now you can see you pen drive has one partition i.e. unallocated space and memory space is your original pen drive memory size. Let’s make this unallocated space to usable memory (Primary Partition).
  • Select the unallocated space, right click on it and click on New Simple Volume. (Or you may go to Action -> All Tasks -> New Simple Volume).
  • New Simple Volume Wizard will pop up. Click Next. Check Maximum disk space in MB is same as Simple volume size in MB. Click Next. Assign the following drive letter anyone from dropdown list and click next.
  • Format this volume with following settings where File system: FAT32 Allocation unit size: Default and Volume label: anything (it is your pen drive name). Perform a quick format click next then Finish.

That’s all. Your pen drive’s unused memory space recovered.

Some other tips on pen drive.
Sometimes you could see that if a single file (like video, image file .iso, zip, rar etc. file) size more than 4GB then you could not copy these file into your pen drive from PC. It happens when your pen drive file system is FAT or FAT32. So to copy those large file into your pen drive you first format your pen drive as file system : NTFS (if your USB pen drive support). It also increases your pen drive performance.

IIT (Indian Institute of Technology), Kharagpur

The Indian Institute of Technology at Kharagpur, first of in the chain of seven IITs, was established in 1950. Scimago rankings rate IIT Kharagpur at 460th position. This ranking is based on the number of publications produced by the students, hence evaluating qualitative research work.

Website: www.iitkgp.ac.in
Contact: +91-3222-255221

The institute offers research in following areas:
Electronics and Electrical Communication Engineering: - The research activities can be grouped under several major areas as mentioned below: Communication Engineering: Digital Modulation Techniques, Digitization of Speech; Bandwidth Compression of Speech Signals; Picture Coding; Spread Spectrum Techniques; Speech Frequency, Multimedia Encryption, Satellite Communication, Mobile Communication, Computer Communication. Visual Information and Embedded Systems: Computer Vision, Computer Networks, Microcontrollers and embedded systems, Fuzzy Techniques and Pattern Recognition, Image and Video Processing, Video and Multimedia Coding, Automated Visual Inspection, Gesture Recognition, Real-time Architectures for Image and Video Processing, Video Transcoding, Multimedia Networking, Video Indexing and Retrieval, Biomedical Image Processing.

Microwave, Millimeter wave and Antenna Engineering: Microwave Antennas, RF and Microwave Integrated Circuits, Millimetric Waves, Magnetostatic Waves, Microstrip Antennas, Phased Array Antennas, EMI/EMC/PSD, Microwave and Millimeter wave Systems and Propagation, Computational Techniques, Radar Cross Section. Microelectronics: CVD for Silox and Polysilicon, Plasma Processing and Ion-beam, High Speed Address Multipliers, Gate Array, Process Modeling, Special purpose Signal Processors and their application in Biomedical Instrumentation, CAD of LSI/VLSI Systems, Device Modeling, MEMS.

Admission Procedure: - Selection is based on performance in GATE and Personal Interview of short-listed candidates. Marks obtained in GATE and in personal interview will have 70% and 30% weightage respectively. Personal interview will be held to test the following: (a) Motivation and aptitude for the programme (b) Oral communication skills (c) Skills in basic science, engineering, and relevant areas. The institute does not conduct any test/interview except for candidates appearing in GATE from XE/XL papers. The cut-off score for getting Counselling letter varies from branch to branch. Applicants can choose a suitable course out of 47 courses offered by the institute by their academic background (degree or equivalent in BE/BTech/BArch/etc.).

At the time of counselling, applicants will be offered seats depending upon their GATE score, eligibility and options given in the application form. Those applicants who do not report for counselling will not be eligible for admission in the session. The selected applicants will have to hand over the original GATE Scorecard along with demand draft towards fees. One advantage with IIT Kharagpur is that there is no need to fill up different form for different department as one can give eight preferences (maximum) in a single application form, which is not the case with other IITs.

You want to say that I can talk to my friend from mobile phone or land phone with free of cost? Are you crazy? Are you not joking with me? These questions are revolving in your mind.

Yes, you can make free Local and STD call in each country. I am not joking. Before I writing this post I test this tricks and make free Local and STD call to my friends. So it is not a joke. Actually I found a website from where you can make free call. The website is https://www.dingaling.ca . You can make ISD call between Canada and US only and make Local and STD call to all other country listed in their drop down menu.

  • At first you have to install an application to your smartphone. If you have not a smartphone then no problem you can use their web browser calling. To make web browser call you need not required contact list, headset or software, just open their website from your computer.
  • For first time you have to register a new account to login or you can use your facebook account to login.

Delete an entire word: Press CTRL + Backspace to delete an entire word instead of deleting a single character one by one. if you want to remove a whole word then this will delete the entire word behind the cursor.

Move Cursor to beginning of the next or previous word: Use shortcut key to move Cursor to beginning of the next or previous word instead of moving cursor one-by-one character space. To move Cursor to the beginning of the previous word, use CTRL + Left Arrow. And to move it to the beginning of the next word, use CTRL + Right Arrow. This will reduce your typing time.

Paste plain text of what was copied: Any formatting text converts and paste as plain text. When we copy text from any source, programs will usually copy any formatting that comes with it. So when we use CTRL + V, it actually paste that formatting text. To paste this as plain text (unformatted text), press CTRL + Shift + V.
Note that many programs like Chrome, Firefox etc. follow this parameter. but not all, particularly Microsoft programs like Word or Outlook does not follow this parameter. For those there's a few alternatives.

File Management Tricks

Rename a file quickly: Most of us press Right-clicking and select rename to change a file name. Instead of this simply press F2 while a file is selected. To alter the name of another file, type TAB without deselecting the current file.

Rename files sequentially in Windows: You actually don’t need to download any programs to perform a batch file rename in Windows. Instead, you can select all the files you want to change, right-click the first one in the list, select rename (or use F2), and type in the name. This will automatically change all the other files with the same root name with a suffix: (1), (2), and so on.
Rename files sequentially


Select multiple files using the keyboard: To select a bunch of files using your keyboard, you can press Shift + down arrow to select a single file or Shift + Page Down to select a large group of files at one time.
