A storage device must have at least one partition before a file system can be set up and store data. The partition can contain all of the storage space on the drive or just some of it. On many storage devices, a single partition will often take up the entire drive.
Many hard drives come with a partition already set up so we can jump straight to the formatting step. We can have the partition formatted with a file system such as the NTFS file system on Windows drives, FAT32 file system for removable drives, HFS+ file system on Mac computers, or the ext4 file system on Linux. Files are then written to that file system on the partition.
When partitions are lost, the drive returns to its original unallocated raw state. When a hard drive or a partition becomes RAW, it means its filesystem cannot be recognized by the computer and therefore is unable to be mounted as a drive. Since the computer can't see any filesystem, it prompts you to format it before you can use this drive.
Partition lost is not as common as data loss. It could happen for various reasons: HDD failure, corrupted partition table and so on. Sometimes we know a partition is lost because we accidentally pressed the wrong key and deleted it.
When a partition is lost, all data saved in it will become inaccessible. If there’s no important data in the missing partition, we can easily solve the problem by creating a new partition or repartitioning the hard drive. However, it is often not the case. Most of the time, the lost partition contains a lot of valuable data and the loss of them would bring us enormous troubles.
The easiest way to recover lost partitions would be using a third party software. H Data Recovery Software features a module designed to tackle this problem.
Here's how to recover data with H Data Recovery Software:
Step 1. Install and run H Data Recovery
Step 2. Choose "Hard Disk Partition Lost or Crash" from the main menu
Step 3. Perform a full scan on the drive
Step 4. View all the recoverable files listed and recover whichever you want.
