Why do you need to format hard drive partition?

When you need to format hard drive partition, it generally means you encounter these situations:

1. Install a new disk/partition a hard drive: When you insert a new hard drive, Disk Management shows it as "unallocated" space, which File Explorer cannot access until it is initialized (MBR or GPT), partitioned, and formatted (NTFS, FAT32, exFAT, etc.). This process will check the drive for errors, and prepare it for use. If need, you can also create partitions for large drives, as it helps protect system files and manage data better.
2. Fix "file system is RAW" issue:  If the file system becomes corrupted or unrecognized, it shows as RAW; you must recover data first, then convert RAW to NTFS, FAT32, or another compatible file system by formatting.
3. Erase data: Some users may want to clean up the partition, disk, or storage medium, so formatting hard disk partitions can be a good idea.
