Lost partition recovery
Deleting a partition changes the disk's layout records. The file system and file content may remain until new partitions, formatting, operating-system installation or normal writes reuse the same sectors.
Understand the symptom
GPT and MBR records identify volume boundaries, types and boot information. A deletion, conversion, cloning mistake or damaged table can make a file system disappear while its internal metadata remains. Recovery must distinguish a simple missing entry from overwritten volume headers, changed sector sizes, encryption containers, multiple former layouts and failing hardware. Guessing a start sector and writing it to the source can make later analysis harder.
What you may see
Disk tools show capacity without a mounted volume after a deletion or layout change.
MBR-to-GPT, resizing, cloning or partition-manager actions may change boundaries or identifiers.
Other volumes may still mount while a deleted or damaged entry is absent.
BitLocker, FileVault or another container may still require its original boundary and valid credentials.
Protect the source
New partition and file-system records may land where the old volume stored essential structures.
Moving boundaries or file-system extents can overwrite old metadata and file content.
A found partition is not automatically the newest or most complete version of the volume.
Do this now
Do not create, extend, shrink, format or mount a replacement volume read-write.
Note volume sizes, order, labels, operating systems, encryption and the exact action that removed it.
Keep source and destination identities, sector-size settings and any logs from migration tools.
Priorities help validate the correct recovered layout rather than accepting the first mountable result.
NEPFOSYS process
A protected sector-level copy preserves current partition and volume evidence before reconstruction.
Partition records, volume headers, file-system metadata and known files help identify coherent boundaries.
Requested folders and files are recovered to separate storage rather than repairing the original disk in place.
A clear next step
Start a case with the exact symptoms, incident timeline, prior attempts, encryption details, and the files that matter most. NEPFOSYS will route the case to the appropriate DFW intake or nationwide mail-in path.
Start with a case reviewQuestions, answered
Sometimes, but writing a guessed partition entry is risky. Recovery is safer from an image, where candidate boundaries and file systems can be tested without changing the source.
The partition entry or volume metadata may be missing or damaged. Unallocated does not prove every underlying sector is blank.
No. The new table and file-system metadata can overwrite old structures, and an approximate boundary may not match the original.
