Most of the time due to bad wiring in the building, fire takes place and all the equipments such as servers, computers, power cabling gets destroyed by the fire. In such case Disaster Recovery plays a significant role.

The data recovery specialists restore lost data in the following situations: fire, flood, lightning, failure or electrical overload and the most varied assaults on computers. Besides all these assaults, there are also hackers and viruses that can take the system down.

The actions for disaster tolerance involve measures such as remote backups, room safes and flame-retardant and anti-spam, server redundancy, intelligent UPS and redundant cabling. We suggest the following practical measures to reduce the risk of downtime or loss from operations of vital information for problems with hard drives that can also help if you need to recover data from damaged hard drives:

Make backup copies, and keep your security data on an external site:

This is very practical for businesses with two or more premises, using the private network to copy data from location A to location B and B to A. If this is not possible, store your backups on the media tapes in another building. Even if one of the sites suffered a disaster you can recover your data from remote copies.

Protect your wiring with a ground system, lightning and removal of sparks:

Many buildings have wiring that were not designed with computers in mind.

Requires the following measures:

All electrical circuits must be grounded. You must measure the impedance of its ground regularly, especially during the drier climate.
Make the load balancing circuit. Give special attention to the polarity of electrical outlets, FNT.
Interconnect all the lands of the installation. If your network meets more than one building or electrical circuit, all must be connected to a single electronic reference ground. If you have different frames of land you will have a difference of potential and can generate noise on the logical network or burning equipment.
Your electrical protection system must include a lightening rod with an adequate number of sinks.

Install a UPS:

The sudden lack of energy is a major cause of data loss. Operations performed in part, references are incomplete and inconsistent transactions some of the consequences of an unscheduled shut down.

Sometimes errors occur in the logical file system that are not readily perceived by the user. Continue writing data on a disk under these conditions will increase the damage, can lead to a situation of no return, even for experts. With a UPS you can do a controlled shut down the system, giving time to write all the temporary data.

Use ScanDisk Correctly:

Norton Disk Doctor are useful for fixing small problems, but if used for a serious problem, they decrease the likelihood that a recovery specialist can recover your data. These utilities sometimes incorrectly interpret those areas, then uses what he thinks is space for operations that may end up writing about real data and moving dirt on the occupied areas. This results in a large
mess.

To determine if you should let Scandisk fix your hard drive, or not, is the number of logic errors. To see this number, go to the DOS prompt and run CHKDSK. If you have less than 10 errors you can correct them with Scandisk. If there are 100 or more errors, your disc is severely damaged and need technical support. If there are errors or more in 1000, immediately turn off the hard drive and contact a data recovery company.

Large files are more prone to corruption than smaller files:

If possible, separate your work into smaller files. Instead of building a single Excel workbook with dozens of worksheets, create multiple workbooks. Large files take longer to update and can involve many blocks of the hard disk, increasing the risk of logical errors.

The recovery file can not be guaranteed, but if conditions are right, much can be done. Even digital formatted disks can be partially recovered. Deleted files still occupy areas of the disk and can be recovered.

If you require a specialist data recovery, you find a company with more experience, ask for some references, make sure about their procedures in advance, and look if they offer a policy "no data, no charge." A few of the companies charge a fee for analyzing your disk. Better way, seek a company that does not charge for diagnosis, so you will have a guarantee that they will do their best for recovery of the data.
