Data Loss Risk Will Grow in 2012

DATARECOVERYUNION.COM03 mins

“70% of businesses that suffer a major data loss are out of business within 18 months” – DTI

Data recovery and security need to become priorities but there are still significant risks that are largely being ignored.

Writing for Forbes, Kevin West, chief executive officer of Klogix, suggested that data loss is reaching levels so high and costing companies so much that it could start to impact the economy.

While he cites the US as an example, the importance of intellectual property protection and adequate security training are the same for businesses around the world.

Untrustworthy offshore outsourcers, malicious cyber attacks from organisations and governments, a lack of training and the rise of Bring Your Own Policies at work will all make the risk of data loss grow in 2012.

Causes of Data Loss: Hardware Failure,Human Errors,Virus Attack,Software Malfunction, Natural Disaster and Power Crisis…

“There is little formal training offered in the subject of cyber security. As a result we rely on self-taught hackers to fill these jobs, people who choose to use their talents to do good work with corporations, but could just as easily turn to cyber crime,” Mr West added, warning that without investment in training, the issue could get worse.

This view was echoed by Mark Dampster Centre for Cyber Security who warned that the cost of data loss is “vast”.

Glossary of Western Digital Hard Disk Drive (Letter H)

DATARECOVERYUNION.COM05 mins

half-duplex
Western Digital Hard Disk Drive A communication protocol that permits transmission in both directions but in only one direction at a time.

hard drive
An electromechanical device for information storage and retrieval, incorporating one or more rotating disks on which data is magnetically recorded, stored, and read. The principal products of WD.

hard error
An error that is repeated every time the same area on a disk is accessed.

hard sectored
A technique that uses a digital signal to indicate the beginning of a sector on a track.

HDA
Head disk assembly. The mechanical components of a hard drive, including disks, heads, spindle motor, and actuator.

head
Also known as a read/write head. An electromagnetic coil and metal pole that read/write magnetic patterns on a disk. A drive with several disk surfaces or platters has a separate head for each data surface. See also MR head.

head actuator
A motor that moves the head stack assembly in a hard drive to align read/write heads with magnetic tracks on the disks.

head crash
The damage incurred to a read/write head when the head comes into contact with a disk surface. A head crash may be caused by severe shock, dust, fingerprints, or smoke, and may damage the disk surface and/or head.

head loading zone
The area on a disk reserved for heads to take off or land when power to the drive is turned on or off. No data is stored in the head loading zone.

head stack assembly
An electromechanical component containing read/write heads and their supporting devices.

headerless format
The lack of headers or ID fields (track format). This format enables greater efficiency and increased user capacity.

HFS
Hierarchical File System. File system developed by Apple Computer for use on computers running Mac OS.

high-level formatting
Formatting that erases all information on a hard drive and sets up the system for storing and retrieving files.

host
The computer to which other computers and peripherals connect. See also initiator.

host adapter
A plug-in board that acts as an interface between a computer system bus and a hard drive.

host interface
The point at which a host and a drive are connected to each other.

host transfer rate
The speed at which a host computer can transfer data across an interface.

hot plug
Act of swapping out a hard drive without having to power down the system or reboot. Hot plugging capability promotes system design flexibility, data availability, and serviceability.

hot swap
See hot plug.

HTTP
Hypertext Transfer Protocol. Protocol used by the World Wide Web to transfer information between servers and browsers.

HTTPS
HTTPS (HTTP over SSL) is the use of Secure Socket Layer (SSL) or Transport Layer Security (TLS) as a sub-layer under regular HTTP application layering. HTTPS encrypts and decrypts user page requests as well as the pages that are returned by the Web server.

hub
A multiple port connection point for network devices, often used to connect segments of a LAN.
