Restore partitions

Active@ UNDELETE is an advanced data recovery tool designed to recover data lost or deleted data, or even information from formatted hard disks.

If you cannot see partitions on your device, or if you know that partitions are missing, you may first scan a device to find partitions.

Restoring a deleted or damaged partition can be done in three stages:

1. Scan disk

Scan a physical device individually or several at once for a deleted or damaged partitions. Usually, only unallocated space needs to be scanned.

For details about scanning read: Scan for deleted partitions and files by their signatures

2. Evaluate scan results

Review scan results and analyse detected partition integrity (restoration status) and validity. Use partition filter and preliminary partition scan to examine detected partitions before restoration.

For details read: Work with device scan results

3. Restore partition

Restore deleted partition at previous location.

Scan for deleted partitions and files by their signatures

A physical device is an installed hard disk, Flash card, external USB disk or any device that holds data. It can be scanned in order to detect deleted (damaged) partitions or files by their signatures at the same time.

Detected partition can be scanned as any other logical drive for files and folders. You can scan detected partition to verify partition content before partition restoration or to be able to recover (copy) files to safe location if partition was deleted or damaged.

To scan a physical device for deleted partitions or files:

1. Initiate disk scan

From Recovery explorer:

  • Click Restore partitions button in view's toolbar or
  • Select a disk (physical device) item and click Scan button in view's toolbar or
  • Use Scan command from context menu
  • Double-click and disk (physical device) node

2. Specify scan attributes

Define scan range and other scan attributes if necessary.

Scan area selector

Select scan area using predefined options: entire disk, unallocated only or specific range - use arrow markers to mark scan area.

Note: Scan area markers shown first and last sectors of scanning area. To enter exact start and end sectors to scan click on sector label and enter exact value in text field.

Save Scan results

Enter path, where scan results will be saved as soon as scan completed.

Ignore Errors

Ignore disk Read/Write Errors

Sectors to skip

Amount of sectors to skip in case of read errors. Use this attribute to avoid scan prolonging on massive bad sectors arrays.

Detect partitions

Select desired File System of a partitions to be detected

Detect files by their signatures

Select this option to specify exact file types to be detected during the scan. With this option, device scan reads each disk sector trying to reconstruct any possible data related to unique file format.

Important: Turn this option off when you only want to detect and restore partition - it will significantly save your scanning time.

Scan results filter

Define scan results refining filter by partition integrity status.

Multiple drive selection

Additional disks can be selected to scan on the Physical disks list to be scanned simultaneously. At least one disk must be selected.

Apply the same settings to all selected devices

All scan options above, can be selected for each drive individually or, when this check box is selected, to be the same for all selected logical drives.

Click Scan to initiate scan of selected disks.

3. Scan selected disks

During the scan:

  • To display or hide scanning events and progress details toggle More\Less Info button at any time.
  • To terminate the scan process, click Stop at any time. Results may be not accurate or complete.

After the scan completes you will see scan results in the Work with device scan results

A Logical Drive scan result appears in the Device scan result view where results can be reviewed and files selected for recovery.

Note: We recommend you to save scan results to designated location for later use - you can use saved scan results to save time on repeated scanning of same volume.
