Loss of data from hard drive or a hard drive malfunction may prove detrimental to the prospects of your business. But data recovery from damaged hard drives is possible if you know what to do and whose help to ask for.

The biggest question is to what extent can data be recovered successfully. Server databases of up to forty-six gigabytes have been recovered. Data have also been recovered from hard drives damaged due to fire or flood.

Data loss attributable to human error or minor system malfunction, without damage to the hard disk, is recoverable by using data recovery software available in the market. Data is often erased accidentally and cannot be found even in the Recycle Bin. This recovery software provides an 'un-erase' feature that will allow you to retrieve data from your hard drive. There are many recovery utilities available on the internet that can be downloaded for free but they provide limited features than the paid versions. The most popular are McAfee Utilities, Gateway GoBack, Ontrack System Suite and Norton SystemWorks that can cost anything between $40 and $60.

However, if the problem is more serious than a mere loss of data, then it is advisable to send the hard drive to a reputable data recovery service provider. If you are having problems with a damaged hard disk, the best thing to do will be to leave it alone and send it to the recovery service provider. People have been known to install recovery utilities on the damaged hard drive but only to worsen the damage. If you are keen on trying to recover the data on your own, then first attach the damaged hard disk to another computer and use as a secondary slave disk before trying to retrieve the data.

Before sending the damaged hard drive for data recovery service, the reputation of the service provider should be taken into account. Companies that have established their credibility in this field should be your first choice. It is also advisable that you ask for an estimate of the cost and time within which the recovery process would be done. Usually, it takes 3 to 5 days for the process to be completed. Depending on the complexity of the problem the cost may be between $300 and $2500. Some of the more established data recovery companies are Ontrack, CBL Data Recovery Technologies, Vogon International, Data Recovery Clinic and Action Front though this is not an exhaustive list.

Though there are ways to recover data, there is no harm in taking measures beforehand. Important data, especially server databases, should always be backed up and businesses should assess the risk involved to take proper preventive measures.
