When a laptop hard drive becomes "unbootable", and you are unable to repair it, you can often save the data on the hard drive by using a "slave drive" recovery method on a desktop computer. As long as the laptop hard drive has not been mechanically broken and the disk is still "readable", you should be successful in accessing and preserving the valuable data on the drive.
I know the frustration when you delete something you shouldn’t have, or your hard drive is corrupted. I will show you how to do a data recovery and hard drive recovery from…
PC
Personal computer.
PRML (Partial Response Maximum Likelihood)
A read channel using sampled data, active equalization and Veterbi detection to accurately retrieve the user data off the disk.
Partition
A way to logically divide a hard drive so that an operating system treats each partition as a separate hard drive. Each partition has a unique drive letter.
Passive Termination
A termination architecture that is used to match the impedance at the end of the SCSI bus by using a voltage divider network of passive resistors.
Peripheral
A device that performs a function and is external…
Disk Doctors Mac Data Recovery software recovers lost and deleted data from HFS+, HFSX file systems on Mac OS X 10.4 and above, which includes LEOPARD.
Recover Lost Data When:
- A volume has been formatted or reformatted
- Volume is inaccessible after re-partitioning or any sort of corruption causing inaccessibility to the volume
- Volume is not getting mounted
- Files and folders are accidentally deleted, Apple partition map is corrupted
- Apple catalog file is corrupted
- Drive has been initialized
- Disk verify and repair fails

MB (Megabyte)
One megabyte as 1,000,000 (one million) bytes.
MFM (Multiple Frequency Modulation)
A method of encoding analog signals into magnetic pulses or bits.
MR Heads (Magneto-resistive Heads)
MR heads were developed to increase area density and improve drive performance. MR heads use separate read and write elements, as opposed to traditional inductive thin-film read-write heads. MR heads use an inductive element for writing data, and a separate magneto-resistive element for reading information. The read element has a magnetically sensitive material that detects data recorded on the magnetic disk surface. MR head construction results in a stronger…

Description:
A strong system of defenses will save your systems from falling victim to published and otherwise uninventive attacks, but even the most heavily defended system can be cracked under the right conditions. Incident Response aims to teach you how to determine…
Landing Zone
The heads move to this location on the inner portion of the disk when commanded, or when the power has been turned off. User data is not stored in this area of the disk.
Laser Textured Media
Laser textured disks minimize the wear and friction on a hard drive. The precision and consistency of the laser zone texturing process is a major contributor to the robustness of newer model hard drives.
Latency
The period of time that the read/write heads wait for the disk to rotate to the correct position to access the desired data.…
Firmware is a type of software stored directly inside hardware components, such as hard disk drives or motherboards, that tells the hardware how to interact with your computer’s operating system. You would typically only need to upgrade your hard drive’s firmware if you installed a new motherboard or upgraded to a new operating system that the drive was not originally intended to interact with. Firmware upgrades are meant to be administered through a floppy disk, but with some extra work you can also apply them with a standard CD as well.
Note: Save a backup copy of each of…
IDE (Integrated Drive Electronics)
A type of drive where the interface controller electronics are incorporated into the design of the hard drive rather than as a separate controller.
Index Pulse Signal
A digital pulse signal indicating the beginning of a disk revolution. An embedded servo pattern or other prerecorded information is present on the disk following index.
Initiator
A device in control of the SCSI bus that sends commands to a target. Most SCSI devices have a fixed role as an initiator or a target; however, some devices can assume both roles.
Initialization
See low-level formatting.…
If you’ve ever installed a hard drive, you have noticed the green board on the bottom of the drive. The green board is known as the hard disk drive’s PCB (Printed Circuit Board).
What A Hard Drive PCB Does?
The PCB is more than a simple way for a hard drive to contain power; it often contains part of the firmware of a drive, which lets the hard drive know how to operate properly and how to read data from the platters. For instance, part of its function is to store information about how many heads are contained within…
Half-Duplex
A communications protocol that permits transmission in both directions but in only one direction at a time.
Half-height Drives
Standard 3.5-inch hard drives are available in heights of 1.0-inch and 1.6-inches. Half-height drives measure 1.6-inches in height.
Hard Disk
A mass storage device that transfers data between the computer’s memory and the disk storage media. Hard disks are rotating, rigid, magnetic storage disks.
Hard Drive
An electromechanical device used for information storage and retrieval, incorporating one or more rotating disks on which data is recorded, stored and read magnetically.
