how HDDs work A hard disk drive (HDD), hard disk, hard drive or fixed disk[b] is hard disk drive a data storage device used for storing and retrieving digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. The platters hard disk drive definition are paired with magnetic heads arranged on a moving actuator arm, which read and write data to the platter surfaces.[2] Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile memory,

retaining stored data even when powered off. Introduced by IBM in 1956,[3] HDDs became the dominant secondary storage device for general-purpose computers by the early 1960s. Continuously improved, HDDs have maintained this position into the modern era of servers and personal computers. More than 200 companies have produced HDDs historically, though after extensive industry consolidation most current units are manufactured by Seagate, Toshiba, and Western Digital. As of 2016[update], HDD production (in bytes per year) is growing, although unit shipments and sales revenues are declining. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), which have higher data-transfer rates, higher areal storage density, better reliability,[4] and much lower latency and access times.[5][6][7][8] While SSDs have higher cost per bit, SSDs are replacing HDDs where speed, power consumption, small size, and durability are important.[7][8] The primary characteristics of an HDD are its capacity and performance. Capacity is specified i
time they are used. It may take more than 6 years before hard drive failure begins, or it might happen within the first year! Common causes of hard drive failure Hard drive data recovery is an 3 types of hard disk important issue that needs some care. Basically, there are two types of hard drive optical disk failure: Hard Drive failure due to a software problem (easy to recover) Hard Drive failure due to a physical malfunction (hard to

recover) With the first failure category, data loss occurs because of; a) Corrupted partition table, b) Damaged boot record, or c) Missing root directory information. It is easy enough to recover a hard drive failure with these https://en.wikipedia.org/wiki/Hard_disk_drive problems. It is much more challenging to recover data from a physically failed hard drive. In this case, it is highly likely that any normal attempt to access the drive may cause further corruption. One of the safest recovery methods I use is to create an external image of the drive using an special imaging tool. Our Workshop based Data Recovery Services My workshop hard disk data recovery procedures are non-destructive - I http://www.pbcomp.com.au/hard-disk-data-recovery-drive-issues.html create a isolated mirror image of a suspect or damaged hard drive - before the recovery process! My workshop service provides data recovery for hard disks, USB drives, flash cards, camera cards, Zip, and floppy disks. This service also covers email data recovery, recovery of lost System files and any other deleted data. Inside your Hard Disk Drive (Anatomy) A hard disk drive contains a number of internal disks, called platters, which are coated with a delicate magnetic substance. These platters spin at high speeds under a mechanical arm (the actuator arm) that moves backwards and forwards over the surface of each platter. On the end of this metallic arm is a small copper wire (read & write head). The computer sends a pulse through this wire - which changes the state of the magnetic surface of a platter as it passes underneath. In this way the files that you store on your computer are encoded into the magnetic substance. Hard disk disks are very complex. They have a circuit board and a number of moving parts. In terms of data recovery, the first thing that you must evaluate is whether it is a hardware problem that is stopping you from accessing your data. Common hardware problems include a faulty circuit board or problems with the act
