Partition Management

A tool to view, search, and open volumes, as well as for simple partition management on MBR and GPT-style disks. Be sure to read the warning before operating.

Partition management includes undeleting removed and lost partitions, restoring boot sector from copy and other tools. You may operate FAT (FAT12/16/32), NTFS, ExFAT, and ExtFS (Ext2/3/4) volumes. However, only FAT and NTFS volumes can be opened and checked for consistency. MBR and GPT layouts are supported. Hybrid (GPT+MBR) partitioning is not properly supported. Other styles (such as Dynamic Disks) are unsupported and partitions on such disks may be shown as found.

Mark the checkbox found to express search and dsiplay lost and removed partitions (FAT/NTFS/ExFAT/ExtFS volumes may be found). For more complex and deeper search use NTFS or FAT search. Volumes opened after NTFS or FAT search are added to the list of found partitions and become available for partition management (e.g. undeleting is possible if a valid boot sectors is found).

To prevent partition express search and displaying dialog box "Partitions" unmark the box Show partitions when open a device or construct a RAID.

Info mode checkboxes:

  • found: display found partitions
  • tables: display AMBR and GPT partition tables
  • detailed: display partition information from tables and boot sectors respectively in several lines per partition

(A) - bootable (active) partition status (Partition column).

Indicators - volume diagnostic indicators (indicate correspondent structure presence):

  • T – partition table;
  • E – table entry;
  • B – volume boot sector;
  • C – boot sector copy;
  • F – MFT(0) for NTFS or Root for FAT (is tested when open FAT volume);
  • f – MFTMirr(0) for NTFS;
  • x – structure is absent or damaged;
  •   (indicator is absent) – structure is not tested (however it may present on a disk).

Red color indicates errors in the partitioning.

Dialog Box "Partitions" · Commands

Attention! Partitioning modification may cause impossibility to boot from the disk or inaccessibility of some partitions after applying. Never modify partitioning of your boot or system disk. Use alternative boot disk or connect your disk as second to another computer. Run the software from the device which won't be modified and save current partitioning to a file on a device which won't be modified. After applying restart the computer or reconnect pluggable device for changes to take effect. Cancel the chkdsk utility (by pressing any key) if it runs automatically at startup as it may cause non-recoverable damage of the data.

Use the Menu button to view the operations available for the selected partition.

Partitioning changes are pending until you push the button Apply or use menu command Apply Partitioning. See also Applying Changes for details.

Open Volume

Open volume to view and recover files.

Open Volume Parameters

View and manually edit volume parameters before actually open volume.

Show Volume Letters

Display volume letters assigned by OS.

FAT, NTFS Search within the Partition

FAT, NTFS Search

Create Image/Clone

Call the dialog box Copy Sectors to create partition image or clone the partition.

Insert the Partition (Undelete)

Insert lost or removed volume into the partition table. Invalid partitions may prevent insertion so they must be removed before insertion. Completely damaged partitioning may be resetted using the command Toggle MBR Signature On/Off applied to the topmost item. You should add partitions from the beginning to the end of the disk.

Remove the Partition

Remove the existing partition or a partition table. Some partitioning errors may be fixed by removing and inserting the partition.

Create RAW Partition

Create unformatted (RAW) partition within the unallocated space. If there are no partitioning errors it is highly recommended to use only standard system tools for creating and removing partitions.

Restore Boot Sector from the Copy

Replace damaged boot sector with a backup copy.

Toggle Bootable (Active) Partition Status

Set or reset active (A) status of a bootable partition.

Toggle MBR/Boot Signature On/Off (MBR On/Off)

Set or reset boot sector signature (0xAA55).

Reset GPT+MBR Signatures (GPT Off)

Reset boot sector signature (0xAA55) and signatures of GPT tables (EFI PART).

Set GPT+MBR Signatures (GPT On)

Set GPT and boot signatures. Available only on GPT disks after resetting.

Undo Action

Undo the last action.

Redo Action

Redo the last undone action.

Undo Partitioning Changes

Undo all partitioing changes.

Reset All Changes

Reset all unapplied changes.

Load from File

Load disk partitioning or rollback data from a file. See Changes for details.

Save Current Partitioning to File

Save current partitioning to a file for a backup purposes. Available only if the device is partitioned and there are no unapplied changes.

Apply Partitioning

Write changes to the disk. See Applying Changes for details.
