Parallel ATA

Parallel ATA - see ATA.


Parity - a property of data which is used in RAID 5 and RAID 6 to provide redundancy.


Partition - a dedicated part of a hard drive which is allocated for some purpose or reason.

Partition recovery

Partition recovery - a process of restoring a lost or deleted partition to its original condition. Unlike general data recovery, partition recovery restores the partition itself, but does not recover separate files from the partition.

Partition table

Partition table - a table where information on partitions, their types, and location on the drive is stored.

Pen drive

Pen drive - see Thumbdrive.

Photo recovery

Photo recovery - the type of data recovery where only picture files (like JPEG) are restored.

Physical damage

Physical damage - mechanical damage of hard drive components. It is impossible to recover data from a physically damaged device using data recovery software.


P-List (Primary defect List) - P-List (Primary defect list) - in a hard drive, a factory defect list holding defective sector reassignments made during a factory first-time surface test. Such defects exist in most disks because it is very difficult to make a high capacity platter with a perfect surface.


PRIVHEAD - one of the control blocks in LDM (Logical Disk Management) metadata used for Windows software RAID.


PSU (Power Supply Unit) - a device which provides energy to computer components. PSU transforms alternating current from the grid to direct current of different voltage for various computer components.
