1. Why RAID data recovery?
As we know, RAID recovery is one of the most complicated and challenging recovery procedures, and therefore, the cost is always very expensive. RAID systems are susceptible to the same ailments that plague single hard drive like logical problems, human error, viruses and physical damage. Otherwise, they may suffer from RAID array failure, controller failure, server registry configurations lost, accidental reconfigurations of RAID drives, multiple drive failure, and so on.
Well, any RAID system may be fault-tolerant, but they are not fault proof. More often than not, most commercial RAID implementations can tolerate the loss of a single hard drive by providing increased data security. In case bad things happen to the RAID controller or configuration (lost, damaged and rebuild by mistake…), your data may be compromised, thus data recovery is necessary.
2. How RAID data recovery works?
The utility will extract the data from multiple HD in a RAID system, and work to rebuild the correct data according to a variety of RAID data array, independent from hardware array card or server system. The essence of the RAID recovery procedures is to crack the algorithm of a variety of RAID cards, or simulate the RAID card to read data scattering among multiple segment hard drives and recompose it in a correct form to a new storage medium by analyzing the data structures of the multiple segment hard drives in the RAID system directly.
Many RAID data recovery companies out there claims to recover lost or deleted data when RAID servers are down using their tools. Several excellent RAID recovery software utilities currently available in the market like WINHEX, Run Time, and R-Studio for example, are prominent at some points.
The merits of these software utilities are well talked most of the time amongst professionals and common users worldwide. Here the list of reviews collected based on in-depth analysis.
WINHEX
With manual analysis available; complicated operations are always in need of experience and expertise.
Run Time
With automatic analysis available; users can not have DirectView of the rebuilt data; inconvenient operation.
R-Studio
With manual analysis available; complicated operations are always in need of experience and expertise.
Getway Raid Recovery Tool

3. Raid Data Recovery Case Studies:
I have a PowerPoint presentation where I extensively use simple animations, only appear/disappear effects triggered by the mouse (not time based), without any smooth transitions. Is it possible to export a PDF where every single step of the animation is on a separate slide?. The problem is that, exporting through the save-as menu, each slide in…
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 contributor to the robustness of our Western Digital 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. For a disk rotating at 5200 RPM, the average latency is 5.8 milliseconds; or, the average time delay between the head arriving on track and the data rotating to the head. (Calculated as one-half the revolution period.)
Local Area Network (LAN)
A system in which computer users in the same company or organization are linked to each other and often to centrally-stored collections of data in LAN servers.
Logical Address
A storage location address that may not describe the physical location; instead, it used as a means to request information from a controller. The controller converts the request from a logical to a physical address that is able to retrieve the data from an actual physical location on the storage device.
LBA (Logical Block Addressing)
A method of addressing the sectors on a drive. Addresses the sectors on the drive as a single group of logical block numbers instead of cylinder, head and sector addresses. It allows for accessing larger drives than is normally possible with CHS addressing.
Logical Drive
A logical drive is a section of the hard disk that appears to be a separate drive in a directory structure. You create logical drives on the extended partition of a hard disk. While 26 letters exist for logical drives, the first three are reserved. A and B are reserved for floppy disk drives, and C is reserved for the first primary DOS partition. Therefore, you can create up to 23 logical drives on your extended partition. Logical drives are usually used to group directories and files.
Logistics Model
The systems by which a company organizes the physical distribution of its products. A hard drive manufacturer’s model might include portions to OEM customers, to distributors, to retail chains or to all of these.
Low-level formatting
The process of creating sectors on the disk surface; this permits the operating system to use the regions needed to create the file structure. Also called initialization. Low-level formatting is performed at the Western Digital factory. There is no need for you to low-level format a Western Digital drive.
Low profile (LP)
Standard 3.5-inch hard drives are available in heights of 1.0-inch and 1.6-inches. Low-profile hard drives measure 1.0-inches in height.
BIOS (Basic input/output system)
A program or set of programs that control the basic functions of the computer.
BPI
Bits per inch. Indicates the density of information on a hard drive. See also bit density.
Backup
To make a copy of a file, group of files, or the entire contents of a hard disk, either for archiving purposes or for safeguarding valuable files from loss should the active copy be damaged or destroyed.
Bad Block
A disk sector that can no longer be used for data storage, usually due to media damage or imperfections.
Bandwidth
The amount of data that can be sent over a given circuit. See also buffer bandwidth.
Bit
An abbreviation for a binary digit which can be either 0 or 1. A bit is the basic data unit of all digital computers. It is usually part of a data byte, or data word; however, a single bit can be used to control or read logic ON/OFF functions. A bit is a single digit in a binary number. Bits are the basic unit of information capacity on a computer storage device. Eight bits equal one byte.
Bit density
Expressed as bits per inch (BPI), the number of bits that can be written onto one inch of track on a disk surface.
Block
A group of bytes handled, stored, and accessed as a logical data unit, such as an individual file record. A block in UNIX workstation environments is the smallest contiguous area that can be allocated for the storage of data. (Note: A different definition of the term is used when referring to the physical configuration of a hard drive.)
Boot
To start or restart your computer; loading the operating system.
Buffer
A temporary data storage area used to make up for a difference in data transfer rates and/or data processing rates between sender and receiver. For example, a printer buffer copies data from the computer and holds it until the printer is ready to print it.
Buffer Bandwidth
The speed of transferring data to or from the buffer.
Bunny Suit
A head-to-toe garment worn by personnel in a Clean Room.
Burst Mode Transfer Rate
The transfer rate into the buffer RAM of the hard disk. This rate does not factor in delays due to latencies or host delays. See also transfer rate.
Bus
A term used for an electronic device in which a number of elements are wired together with a single wire in such way that all the elements can use the same wire to transmit information to other devices on it. Buses are used internally in computers and used to attach computers to peripherals. Only devices addressed by the signals pay attention to them; the others discard the signals.
Byte
A sequence of eight binary digits or bits regarded to be a unit or binary word. The storage capacity of a disk drive is commonly measured in megabytes, which is the total number of storable bits divided by eight million.
Before you choose a hard disk data recovery training, you should know what is necessary condition of the training.
First, the Data Recovery course exposes you to a professional data recovery lab environment, which includes:
It is imperative to learn how to perform physical data recovery in a Class 100 clean room training environment. Even the smallest piece of dust that falls on an exposed drive platter can damage it irreparably, making data unrecoverable.
A warning note to prospective students: Any data recovery training that is taught by self-proclaimed “industry experts” without a clean room is a likely an “edutainment show” or a potential rip-off. You won’t get the detailed instruction you need to do physical data recovery outside of a clean room environment.
Second, choose the training Institutions who can provide a professional data recovery lab experience for students. You will learn how to diagnose faulty PCBs, understand how to swap them with working PCBs. You will also learn critical Surface Mounted Device (SMD) rework skills using a heat gun. This includes identifying donor ROM SMDs and using rework flux to replace non-functional ROM chips.
Third, If you want to learn the all-around hard disk data recovery skills, learning how to exchange drive platters and heads is requisite. This is a critical skill that requires expert instruction. The proper method for head and platter swapping is detailed thoroughly in the Data Recovery course. It is the better if the institutions who also can teach you how to cover voice coil diagnosis and repair. Further more, teach you the secrets of Firmware and Service Area (SA) repair for many different types of drives, including Western Digital, Maxtor, IBM and Seagate hard drives.
The last, choose the classes do not rely on you purchasing any expensive tools, such as PC-3000 to perform data recovery.
