Hard drive is the primary storage media for most of the desktop and laptop PCs. in order to store the data conveniently and organize them in a better way, the hard disk space is usually divided into segments called partitions. The task of dividing the space into different partitions/ volumes is termed as disk partitioning. Moreover, a disk can be divided into at most four and at least one primary partition. A primary partition carries the file system and can become an extended partition which can be further divided into secondary partitions or logical partitions. Different operating systems can be installed at different partitions.

Sometimes, it might happen that the partition gets accidentally deleted, corrupted or damaged causing inaccessibility in the system as well as application software. The system encounters several errors while accessing corrupted or deleted disk partition. All the data and information residing in that partition get lost which may further lead to tremendous data loss. The system may not boot properly or may restart often or may exhibit some unfamiliar disk error. When you suspect that the boot sector of your file system is damaged, you need to check the BIOS setting. The values in all fields of the BIOS should be valid. There are number of error messages that usually indicate corruption in the boot sector, some of the messages are:

Invalid system disk

Disk I/O error

Replace the disk, and then press any key

Non-System disk or disk error

Disk Boot failure

BOOT: Couldn't find NTLDR

Please insert another disk

Consider a scenario, you have created two primary partitions with Windows and one of the Windows partition is again sub divided into two logical partitions. However, when you try to boot Windows partition up, an error prompts and the drive becomes inaccessible thereafter. The error messages may come in the form of following statement:

"Sector not found/read error"

There are two primary reasons behind the occurrence of such error message which are:

Corruption in the partition table of the hard disk.

Any damage to the MFT of the hard disk.

In both the cases, the errors can be resolved by formatting the drive partition and reinstalling the operating system. However, the most important thing is to recover the data which may be lost due to partition formatting. Moreover, in case of partition table corruption as well as MFT damage, the repair process is very complex and slightest mistake can cause whole data loss. Hence, the best possible solution to this problem is to use Windows recovery software and get the data retrieved back using the mechanism. The commercial Windows software recovery tool has in-built powerful scanning algorithm which fetches the partition information first and then find the partitions to recover them.

The Kernel for Windows data recovery is an exceptional tool that easily recovers data from corrupted, deleted and lost disk partitions. It is possible to retrieve data from accidentally deleted hard disk or the drive infected by virus infection. It is capable of collecting data from both FAT and NTFS file partition systems without losing a single bit of information.
