Resize partition in Window 7

Sometime you may have large space unused in a partition. Or may have small disk space available in the partition. In both conditions, you need to resize the partition. In the above practice, we have created a new partition. Now let's extend this partition.
Extend a Partition

In the Disk Management console, right-click on the partition that you want to extend, and click Extend Volume from the menu
Click Next on Welcome screen


For demonstration purpose we will extend 500 MB, You could extend as per your requirement from available space.

Click finish

We have successfully extended the partition size




Sometime you may create single partition during the installation of Window 7 leaving the remaining space of hard disk for further use. Or sometime you may need to resize the existing partition. In this article, we will
·         Create a new partition in Window 7 after installation
·         Resize the partition in Window 7
·         Format the partition in Window 7
·         Change drive letter of partition in Window 7
·         Remove partition in Window 7
For this tutorial, we will use the built-in functionality of window 7. It is always worthy to use inbuilt functionality whenever possible despite using any third party utilities.
·         To create a new partition you must be logged in as an administrator.
·         There must be either unallocated or free disk space with an extended partition on the hard disk.
·         If there is no unallocated disk space, you can create some by shrinking an existing partition, deleting a partition.

Create a new partition in Window 7 after installation

To create the new partition we need to access the Disk Management console.
Click the Start menu button and type diskmgmt.msc into the search box and then right-click the diskmgmt.msc entry and click Run as Administrator item from the context menu


You can also open disk management console from computer management

Click the Start menu button and right click on Computer from submenu and click Manage


From computer management console Click Storage in the right pane to launch Disk management tool

To create new partition select free space and Right click, from sub menu options click new simple volume


Click Next on the Welcome screen


Wizard will show all available space, you can take the empty space and divide it into several drives or you can use the remaining space for a single simple volume

the wizard will ask you to assign a drive letter or path for this volume

On the next screen, You can format or skip this partition.
  • ·         You should format this volume under NTFS to take advantage of NTFS file system.
  • ·         You should not change the allocation unit size setting unless you have a specific reason to change the allocation size.
  • ·         You should assign a label to help you distinguish the new partition from other partition on your system.
  • ·         You could choose a quick format that will take less time, but it will not find and mark bad sectors on the partition. So if have time uncheck this option for the complete format.
  • NTFS file system has built-in compression that is a good choice if storage space is a top priority


On Last screen of wizard you have a summary of your choices. If you need to change any option, you have last opportunity to step back and make changes. When you are satisfied with your choices, click the Finished button

Depending on size of partition wizard will take few minutes to create and format it.
Congratulations you have successfully created new partition, you can also check it in my computer

DATA RECOVERY
Data recovery is the process of recovering data from secondary storage devices ( including a hard disk, USB disk, memory card etc) when the data is no longer accessible normally. No matter how reliable storage device you use, any mechanical or electronic device always have a chance of failure. Fire, flood, earthquake or any other natural disaster can physically damage the storage device. This kind of damage known as physical damage and mostly cannot be repaired by the end user. These kinds of damage require special kind of hardware and technical expertise. Companies deploy several level backup strategies to deal with these kinds of situation.
In addition, there are other non-failure related causes of data loss like accidentally deleting files, repartitioning or formatting a disk etc. This kind of damage known as logical damage. In this section, we will try to recover these kinds of data.

USB data recovery

USB flash drive is one of the most widely used devices. USB flash drives are typically removable and rewritable, and physically much smaller than an optical disc. USB flash drives have no moving parts. Additionally, they are immune to magnetic interference (unlike floppy disks) and unharmed by surface scratches (unlike CD, DVDs). USB flash drive used for storage, backup, and transfer of computer files. They are smaller, faster, have thousands of times more capacity, and are more durable and reliable. Currently, up to 512 GB drives available in the market. USB flash drives use the USB mass storage standard, supported natively by all modern operating systems such as Linux, Unix, Windows, as well as many BIOS boot ROMs.
There is always a chance of data loss from a USB drive. In this article, we will recover data from USB Flash drive.

Attach a pen drive to the system
Move some dummy data in it
Delete all files
Suppose that it was an important data and we need it back. We cannot restore it from Recycle bin.
Whenever you delete a file from USB drive operating system actually does not delete a file, it only deletes file allocation information and set disk space as unused.
Any new data transfer or creation of a file in the drive will reduce your chance of recovery. You should avoid using flash drive after discovering that you need to recover a file. You have a good chance of recovery until this disk space is used by another file.
To recovery file deleted from USB Flash drive download this free file recovery software
Recuva is best to file recovery software. Its freeware but work like the premium file recovery software.
Recuva is developed and distributed by piriform.com. You can always check and download the latest version of Recuva from their official site.
http://www.piriform.com/recuva/builds
From there, click the Download button corresponding to the download type you prefer. You can choose between Installer, Portable, or Slim. I personally recommend you use the portable version of Recuva.
Create a folder
Move the zipped file in it and extract

You can set the folder location to extract the files
Folder contains both 32 and 64-bit application depending on the system from extracted files Launch Recuva application
Recuva provides two mode wizard and advance. First, try wizard mode click Next


If you are looking for the specific file and know its file type, its good idea to select it here for better and faster recovery. We are going to recover all data so select first option and click Next
Select In specific location option and click browse button and select USB Flash drive

Click Next

That's all information Recuva wizard need to search for deleted file Click on Start

Recuva wizard will scan the USB Flash drive. Depending on size of drive and number of files wizard will take few minutes. Wizard will return with the list of files which it found

·         Check box :- Allow you to select the files for recovery.
·         File name :- Name of file
·         Path :- Where this file was located before delete
·         Size :- File size
·         Status :- Current condition of file. Excellent have higher chance of recovery while bad or poor have lower chance or recovery.
·         Comment:- Provide details about the file space, whether it has been replace with new file or not. That's why I have suggested you to avoid using flash drive after discovering that you need to recover a file.

Select the files which you need to recover and click Recover button

You need to provide the location for recovery. Do not use the same location from where data was delete. It is better to create a new folder on another location and use it for recovery.

In few minutes wizard will complete the recovery operations. Click Ok

Open the folder which you select for recovery and verify the data

Now you can move this data back to USB Flash drive.
