External Hard Disk Drives provide great flexible storage option and security by providing a mobile backup option.

With storage capacity running in hundreds of Gigabites, with high rates of data transfer, in addition to the flexibility to plug the external drive to a Laptop, Desktop, Server, Camera or ipod and sold at reasonable prices have increased their popularity dramatically.

However, as the popularity of the external drives containing backups and valuable data are increasingly failing for no apparent reasons. Majority of these failing drives are often of well known commercial brands such as Lacie, Freecom and Omega and with the latest high capacity Maxtor, Seagate or Western Digital hard disk drives models with storage capacity exceeding 320Gb or even 400Gb on a single drive.

The given hard disk drive Models are the cheapest, not fully tested with such hi capacity and worse brands available.

Generally, inside the slick casings, often are poorly ventilated or even not ventilated at all, external hard drives assemblers include the cheapest available drives. If this set up is combined with badly ventilated casing, the combination is catastrophic for any given user, especially when the hard disk drive is of high capacity containing crucial back-up data.

For any given Lacie with multiple drives, this can be a terrible experience with RAID drives and data in excess of 1 terabite. Often with RAID array external drives, the drive failure are more frequent and the damage is more extensive than single drives. Many of the 1 terabyte LaCie external drives contain 250Gb Maxtor IDE in RAID array, inside casing, so badly ventilated, that if they are used regularly, especially within office environment, they are utterly disastrous.

Hitachi has unveiled a drive which has reached the new heights of one terabyte (TB). Its drive looks like any other, but uses perpendicular magnetic recording to make space for all that data.

The current technology generation of LRT-Longitudinal Recording Technology, which records the bits laying horizontally, has been superseded by the recording of the bits standing vertically.

As a single speck of dust entering a hard disk could cause fatal results. It is larger than the distance between the read/write heads and the platter in a hard disk (40 microns, a human hair being 100 microns thick) and its collision with the Hard Disk head would be extremely detrimental.

Our advanced laboratories are equipped with Clean Rooms rated as ‘Class 1000, 100 & 10 ’ where there exists no more than 1000 particles; and ‘Class 100’ where there exists no more than 100 particles whereas with "Class 10", less than 10 particles of 0,5 µm found in our Cabim-Flow which is of "Class 10".

The air quality of the Clean Rooms complies with the applicable standards BS 5295, ISO 14644-4 and Federal Standard 209. Hard disk fabrication requires a ‘Class 100’ Clean Room and UniRecovery undertake all laptop hard drive recovery work in Clean Rooms ‘Class 10’. Commonly established, recovery from “Clicking” hard disk drives, can also be achieved under these specialised Clean Room conditions.
