What is a clean room?
A clean room is climate and dust controlled environments. At Revoco Limited we have a certified Class 100 clean room, this means it is designed to never allow more than 100 particles (0.5 microns or larger) in a space of 1 cubic foot or 29 particles in a space of 1 Meter cube of air.
What is a micron?
A "micron" is an abbreviated term for "micrometer", or a millionth of a meter (1/1,000,000 meters). This is about 0.00004 inches. Lets do some size comparisons, a human red blood cell is about 5 microns across. A human hair is about 75 microns across (of course this depends on the person). Bacteria can be between about .2 microns and 3 microns in size.
How does this affect the Hard Drive ?
In the picture you will see the inside of a hard drive, we have pointed out the hard drive heads that read/writes data and the platter that stores your data.
There is one golden rule, the hard drive heads cannot touch the platter, else your data will be destroyed. To prevent this the heads glides on a layer of air, creating a gap of 0.003 micron between the heads and the platter.
This means that the heads can collide with the platter, with an obstruction as thin as a fingerprint or a particle of smoke.

Data loss is one of the biggest concerns for everyone who creates, modify or enter data into a PC.
Data Loss occurs when you no longer have access to the required data by normal means, generally caused by corruption of file system, data media damage, hard disk crash or virus attack ect.. It can impact anyone doing routine data entry, including businesses or individuals. Depending on the Type of data loss that occurs, it may be possible to recover most, if not all, of the data using various data recovery methods.
There are two forms of failure in a hard drive, logical and physical.
1. Logical failures are usually a result of file-system corruption. Typical symptoms involve the computer being stuck in a loop where it boots, starts to go into Windows, and then reboots itself. You may also get the "Blue Screen of Death". Additionally, you might also have a logical failure due to a virus, accidental deletion of key files or registry components, and in some cases even electro-static discharge. In most cases where a logical failure has occurred, the drive is still recognised by the system BIOS, but it will not boot. Your data should still be intact on the drive, even though it may appear to be inaccessible.
Defragmentation is a necessary computer task for all users. However, there is a lot of conflicting information out there about disk defragmentation. Some people advise doing it weekly... some people will tell you never to do it! Some people say defragmentation hurts the hard drive, some people say that never defragmenting hurts the poor disk even more. Today we clear up the confusion and you will learn how to speed up your computer by defragmenting your hard drive.
Flash drives have become a popular means of storing and transferring data between computers, especially as the amount of storage space on the drives have grown larger. However, flash drive failures are not uncommon and can be especially devastating if you rely on a drive to hold all of your important data. There are a number of things that you can do to take care of your flash drive, extend its life expectancy and keep your data safe.
