Physical disk and partition list

This page covers both the Physical Disks view and RAIDs view. The general principles are identical in both views. However, only Create disk image, Filters, and Filesystem sections are available in RAID view.

General layout and logic

The list is divided into two columns. The left side shows physical disks, and the right shows the corresponding partitions for each physical disk.

Each physical disk and each partition have a checkbox next to them. The toolbar actions work on the checked disks or partitions. Depending on what exactly is checked, some actions are not available. For example, a filesystem scan is not available when multiple partitions are selected, and RAID analysis is not available if only one disk is selected.

While you can technically select both disks and partitions simultaneously, you should not normally do so. Select from either the left side or the right, but not both.

View details

For a physical disk, Klennet Recovery shows the following data:

  • Windows disk number, same as in Windows Disk Management;
  • model name;
  • disk size;
  • bus type used for connection;
  • serial number.

If the S.M.A.R.T. query for the disk reports reallocated sectors, the disk information entry also includes a "Check S.M.A.R.T. attributes" warning.

For a RAID, the left side displays the RAID layout, block size, and disks forming the RAID.

A partition entry contains the following information:

  • drive letter or mount point, if the partition is currently mounted;
  • filesystem type, as detected from the boot sector, if available;
  • partition type, as indicated in the partition table, along with partition table type (MBR or GPT);
  • partition size and starting position on the disk.

Disk image actions

Open disk image

This command opens a disk image file and enumerates the partitions on the image.

Klennet Recovery supports the following disk image formats:

  • raw disk image (plain copy of the disk);
  • VHD (fixed size or dynamic);
  • VHDX (fixed size or dynamic).

Create disk image

This command asks you for the target disk image format and file name and then opens the integrated disk imager.


Filters are useful if you have many disks in the system. You can filter disks, partitions, or both, by disk model, capacity, bus type, and other characteristics.

If the filter is active, its corresponding button is highlighted in red.

SMART and NVMe device health information

These two buttons open S.M.A.R.T. or NVMe self-monitoring detail pages if exactly one disk is selected and the disk is capable of self-monitoring.


This section deals with RAIDs. Select at least two drives or two partitions for the RAID operations to become available.

Read metadata

Read known metadata, if any, from selected disks or partitions.

The following metadata formats are supported:

  • DDF (Common RAID Disk Data Format), used by LSI and Promise RAID controllers (select physical disks);
  • md (Linux software RAID) (most often on partitions, but sometimes on physical disks);
  • LDM (Windows dynamic disks) (select physical disks).


Start RAID analysis on the selected disk or partition set. Use this option if the array metadata is unavailable and you do not know the parameters.

See RAID analysis page for more details.


Manually define a RAID on the selected disk or partition set. Use this option if the array metadata is unavailable, but you know the correct parameters.

See Manual RAID definition page for more details.


Define region

This command creates a simple partition (defined by its starting position and size) on the selected disk. You cannot create a partition based on another partition.


Start scanning the selected disk or selected partition for a filesystem of a specific type. Only one filesystem type can be analyzed at any one time. If there is a valid boot sector on the partition, its corresponding filesystem type is highlighted in bold.

While it is technically possible to run several scans of the same disk or partition in parallel, I strongly recommend that you avoid it.
