Recovering data from a damaged media is known as data recovery. Data is lost due to a number of factors:
- Virus attacks
- Reformatting of partitions with the files
- Accidental deletion of files by employees and emptying of the recycle bin
- Appearance of bad sectors on the hard drive
- Sudden electric surges
If any such eventuality occurs, the computer user must first try to prevent or minimise data loss. Recovery of data can be thought about, when all preventive measures fail.
Preventing Data Loss
- The most common of all natural disasters causing data loss is an electric surge. Electricity surges through when power is restored after a break down. Whenever there is a power failure a computer must be restarted half an hour after power restoration.
- Busy computer users drink their beverages while working. Drinking liquids near the computer is potentially dangerous. A single fallen drop is enough to short-circuit the computer. Whenever accidental spills occur the computer must never be powered on.
Minimising Data Loss
- Unusual noises from the computer indicate a hard disk crash. If such noises are heard, the computer should be switched off to minimise data loss. For, hard drives spin fast at an rpm of 7200 to15000. Data gets damaged when the read/ write head scraps disks revolving at such high speeds.
- Data can also be lost when a computer gets accidentally damaged. The external trauma badly impacts the sensitive internal components. Reduction in data loss is possible, by powering it off.
- Data loss due to viruses can be minimised by seeking professional help after the use of anti-virus software fails.
- Finally, if any problem occurs, data recovery should not be attempted by repeatedly switching on and off the computer. Such methods might lead to a loss of data, beyond the point of retrieval.
In spite of taking all the precautionary and preventive measures people still face the panicky situation of losing all data. Losing data has forced businesses into bankruptcy. Fortunately, lost data can be recovered in many cases.
How is Data Recovered?
Data recovery companies employ skilled and experienced engineers. Basically, all the engineers know how to resolve the minor problems in a hard drive. Individually, they specialise in dealing with one particular part of the hard drive.
These engineers work systematically when presented with data recovery cases.
- They take the hard disk drive for an analysis to a class 100 room. Cleanliness of this sort is an important requisite. Any mild contamination can lead to a head crash.
- The specialised engineers assess the damage and get back to the client. The amount of data that can be retrieved, the time taken and the cost of recovery are specified.
- Upon client consent, many devices are used to process the disk. If data is lost due to hardware damage, the necessary components are repaired or replaced. Hard disk drives are individually assessed for damage and each disk is rectified separately.
- And, in case of a logical failure, the mirror image of the damaged drive is created. Recovery work is attempted on the mirror image.
- Recovered data is immediately sent back to the client.
Companies that Recover Data in the UK
Data recovery companies in the UK not only recover data, they also sell data recovery software. This software enables clients to recover data themselves.
Companies that sell data recovery software online, allow their software to be downloaded free of cost. The customer can view the lost file using this software. If all the contents of the file are undamaged and available, the client pays for the registration key of the software. This enables the recovery of the file.
If the damage to the hard disk drive is intense, and data recovery software is not of much use, customers seek professional help.
Many companies successfully recover data in the UK. A few of the most reputed ones are mentioned below:
- ‘Fields Data Recovery’
Engineers in ‘Fields Data Recovery’ are highly skilled and experienced. They are able to recover the full data in almost 90% of the cases.
- ‘Easy Recovery’
This Company offers free consultation, free analysis and charges only if they are able to recover data.
- ‘Data Recovery Corp UK’ is another reputed company.
Data can be lost due to plenty of reasons. And any data loss plays havoc with businesses. Data recovery companies protect business establishments from eventually closing down, by recovering their data for them. Many companies in the UK work on the principle of ‘no recovery, no charge.’ And, client information is always kept confidential.
