Lost Partition Recovery

When we are using a windows operating system then we usually divide the hard disk into several partitions. First partition is used for loading operating system and rests of partitions are used to store data. The advantage of dividing the hard drive into various partitions is that if anything goes wrong with the operating system then it does not affect our data.

Sometimes it happens that operating system does not boot up either because of NTLDR goes missing or Boot.ini got corrupted. To fix the operating system we use Restore CD. The restore CD load the operating system again by formatting the partition of the hard drive. Thus we loose all the data on that partition of the drive. It may also happen that our hard drive crashes and we reload the operating system only finding that other partition of the drive is not accessible.

To fix the lost partition we require good data recovery software. Partition recovery process is a significant part of data recovery. Partition recovery utility helps in recovering lost partition from accidental partition format, partition lost due to viruses, or partition becoming inaccessible. Partition recovery utility provides recovery from FAT 16, FAT32, NTFS & NTFS5 file system.

Partition recovery software should also be able to recover corrupt master boot record. The master boot record (MBR) is located on the first sector of the hard drive and is responsible for starting the Windows boot procedure. MBR contains the partition table for the drive as well as a small program called the master boot code, which is responsible for locating the active, or bootable, partition, in the partition table. Once this occurs, the partition boot sector takes over and begins loading Windows. If the master boot record is corrupt, the partition boot sector can’t do its job and Windows won’t boot.
