Partitioning a hard drive, which is having more storage capacity, can make a hard drive function more proficiently. Every small file uses one entire cluster of hard drive storage space. If the hard drive is having larger storage capacity then Operating system typically uses larger cluster size, which may frequently waste the hard disk storage space. Therefore, when hard disk is partitioned, smaller cluster size is used by each logical drive thereby avoiding wastage of disk storage space. Partitions also offer tremendous flexibility in logical organization of hard drive. Partitioning allows single hard drive to store one or more Operating systems. You can have Windows XP in one partition and another OS like Windows 7 in the second partition.
Generally, every Operating system has its own in-built partition tool. Windows OS has different partitioning tools like FDISK and Disk Management utility. FDISK is a command-line program used by DOS and older versions of Windows OS (i.e. up to Windows Me) whereas Disk Management utility is a graphical partitioning program used by Windows 2000 and above versions of Windows for partitioning hard drive. Originally, users are not able to change size or type of partition until you erase the existing partition. However, third party utilities like Partition Magic allow you to resize the partition without losing the stored data. After partitioning the hard drive, you need to format the partitions. Windows OS supports two types of file system i.e. FAT and NTFS. Older versions of Windows like Windows 95, Windows 98 and Windows Me use FAT32 and older versions of FAT file system, whereas Windows 2000, 2003, 2008, NT, XP, Vista and Windows 7 use NTFS file system. NTFS has several improvements over FAT like high security to the files and folders, advanced data structures to improve the performance. It provides high reliability which reduces the chances of losing the data from NTFS partitions when compared to other partitions. But this is also prone to data loss when you accidentally delete NTFS partition while on the verge of deleting some other partitions using disk management utility. Under such circumstances use partition recovery toool to restore data from accidentally deleted ntfs partition. Sometimes, you may encounter issues due to bad sectors on hard drive. In such instances, reformatting is the most efficient way to solve the problem. When you reformat the drive and it re-installs the disk drivers.
Sometimes, while making partitions to install multiple OS, if power surge problems occur or if your system gets turned off abruptly then you may encounter data loss. You can create, delete, format the partitions using in-built utilities and also using third party utilities. Third party utility like partition magic shows information about partitions of your hard disk. Suppose, you do not want to use other Operating system, which is installed on, second partition and you want to delete it. In such cases, you can use disk management or third party utility to delete the partitions. If you have deleted a partition from Windows XP based computer and you badly need the data stored in it, then using deleted partition recovery tool you can easily restore deleted partition on Windows XP. Sometimes, instead of deleting second partition, which you do not want to use, you may accidentally delete the first partition. When you delete the first partition, the data stored on that partition gets deleted.
To avoid data loss, you are supposed to create backup of the entire partition data. While deleting the partition, you will see a warning message that, all the data stored on the partition will get deleted. Therefore, check again that you are deleting the right partition, which is not needed further. Even if you have deleted the partition there is no need to worry, because Deleted Partition recovery utility is able to restore deleted partition data from Seagate hard drive and in addition to that recover deleted partition data from Western Digital hard drive and other brands of hard disks on Windows. When you delete a partition, only the partition table information gets deleted making that partition inaccessible. Partition data is still present on hard drive until they are overwritten by new data. Therefore, do not use that drive to save new data to avoid overwriting. Deleted NTFS Partition recovery software also has an ability to recover lost data from inaccessible partitions and also restore partition on external hard disk.
Follow the below mentioned steps, to recover lost data from accidentally deleted partitions:
Step 1: Download and install deleted laptop partition recovery software and launch it. The main window appears where you can see three options like "Recover Files", "Recover Photos" and "Recover Partitions / drives" as shown in Figure 1. Click on "Recover Partitions / hard drives" option to recover lost data from partitions.
Figure 1 : Main Window
Step 2: Select "Partition Recovery" option from next window then select the drive from where you have deleted the partition and click "Next" button as shown in Figure 2.
Figure 2 : Select Physical Drive
Step 3: The software starts scanning to find deleted partitions. Once scanning is completed, deleted partitions will be listed. Select appropriate partition and click "Next" button as shown in Figure 3.

Step 4: Select file type if you want else you can skip this step to continue with thorough scanning by clicking on "Skip" button as shown in Figure 4.

Step 5: 5. After scanning, recovered data can be viewed using "File Type / Data Type View" as shown in Figure 5.
