7 ベストパーティション復元ソフトウェア（無料＆有料）
という場合 ハードドライブ または SSD suddenly shows as 未割り当て or a partition disappears, most users immediately search for the best partition recovery software または best partition recovery software free option. This is understandable. A missing partition often means lost access to documents, photos, or business-critical files.
In practice, however, partition recovery is not always the safest first step. Most partition recovery tools work by rebuilding the partition structure and writing it back to the disk. If the reconstructed partition is inaccurate or partially corrupted, it may fail to open or overwrite existing metadata, leading to secondary データ損失.
In this guide, we objectively review 7 best partition recovery software tools that genuinely support partition restoration, including both paid and free solutions. More importantly, we explain the real-world risks of direct partition recovery and introduce a safer, data-first approach using Magic Data Recovery when your data truly matters.

What Is Partition Recovery Software?
Partition recovery software is designed to locate and restore lost or deleted disk partitions. Instead of recovering individual files, these tools attempt to rebuild the partition entry itself and make the volume accessible again.
How Partition Recovery Works
ほとんどの場合 失われたパーティション are not physically erased. Instead, the partition table (マスタブートレコード または ジーピーティー) becomes damaged or overwritten. The best partition recovery software scans the disk for:
- Previous partition boundaries
- File system signatures (エヌティーエフエス, FAT32, エクストラファット)
- Boot records and metadata structures
After detection, the software reconstructs the partition and writes it back to the disk so the operating system can recognize it again.
典型的な使用シナリオ
Partition recovery tools are commonly used when:
- A partition is accidentally deleted
- A disk shows as unallocated
- A partition disappears after OS reinstallation
- Disk management operations go wrong
- について パーティションテーブル 汚れる
Although effective in many cases, this approach carries inherent risks.
Risks of Using Partition Recovery Software Directly
Before choosing even the best partition recovery software free or paid tool, it is essential to understand the potential downsides.
一般的なリスク
- The recovered partition cannot be opened
- ファイルシステムのエラー remain after recovery
- Incorrect partition boundaries cause missing files
- Existing metadata is overwritten
- Secondary data damage reduces recovery chances
Because partition recovery modifies disk structures, any mistake can make file-level recovery more difficult later. This is why professionals often avoid rebuilding partitions until data is safely extracted.
Criteria for Evaluating the Best Partition Recovery Software
Not all tools are created equal. A reliable solution should provide:
- Accurate partition detection
- Support for NTFS, FAT, and exFAT
- Compatibility with MBR and GPT disks
- Preview before applying changes
- Clear warnings before writing to disk
Free tools are useful for diagnostics, while paid tools often offer better usability and guidance. Neither option eliminates risk completely.

A Safer Strategy: Recover Data Before Rebuilding the Partition
Professionals often avoid immediate partition reconstruction. Instead, they recover files first.
Why File-Level Recovery Is Safer
File recovery tools operate in read-only mode. They scan raw disk space and extract files without altering partition tables.
This approach:
