Things You Should Know Before Requesting Data Recovery Services from Docomo
Docomo’s “Data Recovery Service” mainly deals with physical failures (such as circuit board damage, water damage, or power supply issues). In these cases, it is optimal to request Docomo’s data recovery service, as specialized cleanroom environments and component replacements or chip-level analysis are required.
However, for logical issues such as accidental deletion, formatted drives, or unrecognized disks, recovery might be possible through data structure reanalysis rather than physical repair. These logical failures can be fixed by individuals with the right knowledge and tools.

What is a Logical Error? Cases Not Supported by Docomo Data Recovery Service
A “logical error” refers to a situation where, even though the hardware itself is functioning normally, issues with the file system or partition information prevent data from being visible.
Typical examples include:
Accidentally deleting files or folders
Formatting the drive
Displaying “Cannot access” or “RAW format”
These issues can be recoverable by Docomo, but the recovery process may take several days to weeks and can be costly. Additionally, there may be concerns about privacy since personal data could be handed over to an external service. Next, we will introduce ways you can attempt recovery on your own.
Manual Data Recovery Using WinHex (For Advanced Users)
For analyzing logical data failures, a binary editor like WinHex (by X-Ways) is used.
This tool allows you to directly view and edit raw data on a disk and reconstruct damaged partitions or deleted files.
Basic recovery steps using WinHex (example: NTFS):
1. Open Disk Management (press Win + R, type “diskmgmt.msc”) and check the status of the disk.
2. If the drive shows as RAW, file system analysis is generally required.
3. Open the drive with WinHex. Analyze the NTFS file system (refer to the official Microsoft NTFS Structure Documentation). In this case, the file system was corrupted.
4. Search for the backup DBR signature (EB5290) from the end of the partition.
5. Overwrite the sector containing the DBR with the backup DBR.
6. Check Disk Management again to confirm that the drive can be accessed normally.
👉 However, this method requires advanced knowledge and experience, and improper operations could lead to further data damage.
