Hard Drive

 

In this article I will talk about what is hard drive and I am going to explain how it works .I will also explain the tasks of hard disk drive

The hard disk is the largest and usually the largest hardware device for storing data on a computer. The operating system, software, and most other files are stored on the hard disk. The magnetic disk drive is sometimes referred to as "C" drive because Microsoft Windows defaults to drive letter "C" for the primary partition of a computer's primary hard disk. Although it is not a technically correct term, it is still widely used. For example, some computers have multiple drive letters (for example, C, D, and E) that represent areas on one or more floppy disks. The hard disk drive is also called hard disk (its abbreviation), diskette, hard disk drive.Seagate, Western Digital, Hitachi and Toshiba are among the best known hard disk manufacturers.

You can usually buy these brands of third-party drives and these drives in stores and online, for example through the company's websites and via sites such as Amazon. Unlike volatile memory such as RAM, a hard drive retains its data even when it is turned off. Because of this, you can restart a computer, which closes the hard disk. However, they will still have access to all data when they are reactivated. The floppy disk contains sectors on tracks stored on rotating disks. These disks have magnetic heads that move with an actuator arm to read data and write to the reader. The hard drive of the computer is not the only type of hard drive, and SATA and PATA are not the only way to connect to a computer. In addition, there are many sizes of hard drives, some very small and others large enough. For example, the ordinary flash drive also has a hard drive, but it does not run like a traditional hard drive. Flash drives have built-in solid-state drives and are connected to the computer via USB.

Another USB hard drive is the external hard drive, which is basically an ordinary hard drive that has been placed in its own case, so it is secure outside the computer case. They are usually connected to the computer via USB, but some use FireWire or eSATA. An external box is a case for an internal hard disk. You can use one if you want to "convert" an internal hard drive to an external drive to create your own external hard drive. They also use USB, FireWire, etc.magnetic disk capacity is a key factor in getting someone to buy a specific device, such as a laptop or phone. If the storage capacity is rather low, it means that the files are filled more quickly, while a high volume drive can handle a lot more data. The choice of a hard disk depends on how much space it can hold. For example, if you need a tablet that can store many videos, be sure to use the 64GB drive instead of 8GB.The same thing applies to hard drives on the computer. Do you record many videos or HD images or are most of your files backed up online? For offline storage at home, you may be able to purchase an internal or external hard drive that supports 4 TB or 500 GB.
A simple task you can do with a hard drive is to change the drive letter. This will allow you to reference the reader with a different letter. While the main hard drive is usually called drive "C" and can not be changed, you can change the letter of an external hard drive from "P" to "L" (or any other valid letter). Another thing that is really easy with a hard drive is to check how much free space is available. This is especially important if you have too little disk space, but also for a fluid system. You can uninstall programs that you do not want or that are too large, and delete or copy files elsewhere if there is not enough free disk space. You must format the drive or divide the drive into sections before you can install an operating system or save files. During the first installation of the operating system, a new hard disk is usually formatted and assigned to a file system. Otherwise, a disk partitioning tool is a common way to manipulate the drive in this way. If you are working with a fragmented disk, free defragmentation tools are available to help you reduce fragmentation. Defragmenting a hard drive can sometimes speed up your computer.Since all data on a computer is actually stored on a floppy disk, it is common to delete data from the hard disk safely. For example, before selling the hardware or reinstalling a new operating system. This is usually done with a data destruction program. Your computer's hard drive is used again and again if you do something that reads or writes data to the drive. It is therefore normal that one day there will be a problem with the device. One of the most common problems is a hard disk that makes noise, and the best first step in troubleshooting a disk malfunction is to run a hard disk test.

Data Recovery Process

Today in this article I will talk about the process of data recovery related to many storage devices that we use in day to day life. I will also explain why data recovery is required and how data can be recovered?

Data recovery is the process of recovering inaccessible or damaged data from a digital medium damaged or damaged in one way or another. Data recovery can be used to recover data from various devices such as hard drives, memory cards, tapes, mobile phones, PDAs, floppy disks, CDs, DVDs, data cartridges, Xboxes and many other elements.Data recovery may be required for various reasons, for example: hardware failures  (the tape was "chewed", the hard drive failed, a fire, a flood, or a logical error occurred. The firmware, the semiconductor failure, or the accidental failure / deletion of a storage device may have been dropped. The hard drive has been formatted "by mistake. All of these cases require the services of an enterprise. Professional data recovery, if the data have such value (whether sentimental or financial), that the cost of the services is less than the perceived value of the data.

There are many ways to recover data from digital media, which can be very different. The simplest method may be to run the basic software on the storage medium. This is always a dangerous idea because the recovery data could overwrite the data being recovered. There are more complex commercial software tools that do this work more professionally. No hot fix should be attempted until the original media is mapped so that the restorer can work on a "backup" of the original software. Most professional companies also adopt a second image if there is a problem with recovering the first image.

The next problem is what happens if the hard drive or storage device does not work. This is a problem for smaller "data recovery companies" when they involve serious data recovery companies (such as my company disk labs) specializing in higher priced data trends.

Once you have found the right company for you and the data storage device is no longer working, it is very likely that the digital media will need replacement parts. There are specialized organizations that sell spares for old hard drives and difficult access to data recovery companies to keep the original data long-term, so that data can be mapped to a device stable storage so you can duplicate them again.
The data recovery job is usually complete when a list of all recovered files is sent to the client. Once the client has approved this list of files, the data is sent to an appropriate medium. This can be a hard disk drive, a floppy disk, a CD or a DVD. If a file is considered critical, you can also encrypt it and send it to the client by email.

It should be noted that in extreme cases the data can not be recovered. The best advice we can offer the customer is: "Once you have lost data, you need to turn off your device and send it to a professional data recovery company to maximize your chances of recovery. A wrong approach can also destroy Data Recovery chances.

Solid State Drive

In this article i am going to talk about Solid State Drive .I will also explain what is SSD and what are the uses of this drive .i will also cover the features that are involved in this drive.

A Solid State Drive (SSD) is a type of nonvolatile storage medium that stores persistent data in solid state flash memory. An SSD consists of two main components: a flash controller and NAND flash memory chips. The configuration of the SSD architecture is optimized to provide high read and write performance for sequential and random data requests, SSD are sometimes called flash disks .Unlike a hard disk (HDD), an SSD contains no moving parts that can be damaged. A conventional hard disk consists of a rotating disk with a read/ write head on a mechanical arm called an actuator. The hard disk mechanism and the hard disk are integrated into an integrated unit. Businesses and computer manufacturers have generally used turntables because of their lower unit cost and longer lifetime, although SSD are now common place on desktops and laptops. A rotating hard disk reads and writes data magnetically, one of the oldest storage media in continuous use. However, magnetic properties can lead to mechanical failures. Conversely, an SSD reads and writes data to a substrate of interconnected flash memory chips.

To avoid volatility, SSD manufacturers are developing devices with floating gate transistors to contain the electrical charge. This allows an SSD to retain the stored data even when it is not connected to a power source. Each floating gate transistors contains a single data bit, called one for a charged cell or zero if the cell has no electrical charge. SSD is better than HDD, here are the some examples like SSD can reduce boot time from about 35 seconds to about 10 seconds. The writing speed of a hard disk can be between 50 and 120Mbps,compared to 200-500Mbps, for an SSD. A hard disk can perform between 50 and 200 I/ O operations per second, while a comparable SSD can reach 90,000. In addition, some professional-grade rack-mount SSD claim to be able to handle millions of operations per second .Solid state drive offer faster storage and performance advantages than hard drives. Companies that increasingly need higher I / O have driven the development and adoption of SSD. Because it has lower latency than hard disks, they can effectively handle heavy reads and random workloads. This lower latency results from the ability of an SSD flash to read data directly and immediately from a particular location in the SSD flash cell.

A 100% Flash bay requires only SSD as storage. A hybrid flash bay combines disk space and SSD with flash memory, used to cache hot data that will then be written to a disk or tape. In server-side flash configurations, SSD are installed on computers to support targeted workloads, sometimes in conjunction with network storage .Servers, laptops, desktops, or high-performance applications that need to provide real-time or near real time information can benefit from this technology. With these features, enterprise it is ideal for offloading, transactions database transactions, avoiding booting with Virtual Desktop Infrastructure (VDI), or within a storage array for local storage of data. Hot for off-site storage in a hybrid cloud Scenario.

Solid state drive are used in a number of consumer devices, including computer games, digital cameras, digital music players, laptops, personal computers, smartphones, tablets and USB sticks. These devices are not designed to provide the same performance and durability as a corporate SSD. This drive offer faster storage and performance advantages than hard drives. Companies that increasingly need higher I /O have driven the development and adoption of this drive. Because SSD have lower latency than hard disks, they can effectively handle heavy reads and random workloads. This lower latency results from the ability of an SSD flash to read data directly and immediately from a particular location in the SSD flash cell. With these features, enterprise it is ideal for offloading transaction database transactions, avoiding booting with Virtual Desktop Infrastructure (VDI), or within a storage array for local storage of data. Hot for off-site storage in a hybrid cloud Scenario. Several features characterize the design of an SSD. Since no moving parts are used, an SSD is not subject to the mechanical failure that occurs with the hard drives. It is also quieter and uses less power than its hard drive counterpart. And because SSD weigh less than hard drives, they are good for laptops and mobile computing devices. In addition, the SSD controller software includes predictive analytic that warns a user of a potential drive failure. Because flash memory is flexible, all flash array vendors can change usable storage capacity using data reduction techniques.
