Recover partition after format hard drive
Drive partitioning is the act or practice of dividing the storage space of a hard drive into separate data areas known as partitions. A partition editor program can be used to create, delete or modify these partitions. Once a drive is divided into several partitions, directories and files of different categories may be stored in different partitions. More partitions provide more control but too many may become cumbersome. The way space management, access permissions and directory searching are implemented depends upon the type of file system installed on a partition. Careful consideration of the size of the partition is necessary as the ability to change the size depends on the file system installed on the partition.
A primary partition contains one file system.An extended partition is a primary partition which contains secondary partition(s).
With Microsoft Windows, DOS, and OS/2, the standard partitioning scheme is to create a single active primary partitions or drive. The designation for this drive is the C: drive, where the operating system (OS), utilities, applications, user data, and page/swap file all reside.
If the primary partition are destroied,the consequence is very serious.but does not need to worry,data recovery software have enough ability to help you.
When a partition is deleted, in general, only its partition table entry is removed from a table; and although the data is no longer accessible, it still remains on the disk until being overwritten. Specialized recovery utilities, (such as Diskgetor), can locate lost file systems and recreate a partition table which includes entries for these recovered file systems. However, some disk utilities may also overwrite a number of beginning sectors of a partition they delete. For example, if Windows Disk Management (Windows 2000/XP, etc.) is used to delete a partition, it will overwrite the first sector (relative sector 0) of the partition before removing it. It may be possible to restore a FAT32 or NTFS partition if a backup boot sector is available.
