How to Recover Unallocated Partition Data from Hard Drive?

Partitions are logical divisions created on a hard drive or external storage unit where the operating system stores information. Any damage to your hard drive, or virus attack or system crash might turn the partition(s) as unallocated and result in data loss.

Some of the reasons for data loss from disk partitions are:

1. Damaged Partition Table

Partition Table contains information about disk partitions on the hard drive. When the partition table goes missing, damaged or corrupt, the disk partition(s) or the entire hard drive might become unallocated. This means you can’t access your data saved on the partition or hard drive.

2. Malware/virus attack

Virus or malware attacks can corrupt or damage the file system on a hard drive. This may sometimes result in unallocated or lost disk partitions, due to which you might lose data.

3. Formatting/deletion while reinstalling the operating system

When you reinstall an operating system, you get the options to format or repartition the hard drive. You may sometimes accidentally delete or format a partition, resulting in data loss.

4. System crash

In case your system is crashed, you might get startup errors and the hard drive or disk partitions might not be detected. In such a situation, you’re unable to access your data stored on the hard drive.

5. Partition becomes RAW

Hard drive partition became RAW when it is not formatted with the file systems such as NTFS, FAT16/32, etc. If your drive partition(s) turns RAW, you couldn’t access your data stored on it.
