Recover deleted NTFS/FAT32 partition

When a dynamic volume is deleted, the OS clears the boot sector of the partition and removes the volume entry from the Disk Management MMC, but leaves the rest of the data on the partition untouched. Both NTFS and FAT32 stores a backup of the boot sector and if restored, then it will be possible to recover a deleted partition.

To recover a dynamic NTFS volume:
  • Start the Disk Management snapin (Go to Start, Programs, Administrative Tools, Computer Management and select Storage)
  • Recreate the original volume by right-clicking the unpartitioned space and selecting New Partition. Specify the exact size of the original volume, but do not perform a format of the volume.
  • Use Dskprobe.exe to recover the backup boot sector (You might need Dmdiag.exe to find the backup boot sector). More Info Recovering NTFS Boot Sector on NTFS Partitions (MS KB153973)
  • After restoring the NTFS boot sector quit Dskprobe.exe
  • In the Disk Management snapin go to the Action-menu and click Rescan Disks to mount the volume for immediate use.
To recover a FAT32 volume:
