Restore Lost Partition from Unallocated Space

“Since couple of months I am using Seagate hard drive as external drive to keep back up of all important information. But today, all of a sudden, one of the partitions is shown as unallocated space and entire data that had been saved in this partition is now missing. Partition isn't showing up on my system and it is stating as whole partition is unallocated. How do I retrieve lost partition from unallocated space? Please help!!!”

Unallocated space in partition refers to a place which is not currently used by drive. It might have complete files, fragments and other program files generated by operating system. Unallocated space emerges because of loss of partition. To make sure whether partition is lost or not, you can follow these steps: Click on Start Menu and open Control Panel then select Administrative Tools icon and click on Computer Management. Again click on Disk Management from left frame of next screen, this will display list of installed drives on your computer. If partition doesn't appear there, then that partition is lost completely.

However, file system is responsible for maintaining all files present in partitions; drive without file system is known as unallocated partition space. If you want to recover lost partition data from unallocated space then you need to make use of eminent partition recovery utility.

Some other scenarios for data loss from unallocated partition space are:

  • File system corruption that leads to inaccessibility of drive partitions
  • Registry error or software malfunction can cause operating system crash and also lead to loss of partition data from unallocated space
  • Accidental deletion or formatting is also a main reason for partition data loss
  • MBR, which holds partition table, can get corrupt or damaged due to malware attack; this might sometimes causes invisibility of partitions on drive hence leading to data loss
