The essential data Recovery Report

Your worst nightmare just became a horrifying reality. You keep hearing that little voice in your head mockingly shout “you should have backed up these things” The voice continues to echo across the head to make a quick inventory all the important information you just lost your database ..

Soon call a technician and have come to check the computer out, only to hear the worst news of all. Your data has been lost. When a disk drive fails, it is too late to worry about what “should have done.”

Today data recovery is an industry of millions of dollars. The number of data recovery firms out there seems to be greater than the number of fast food restaurants around the globe. These companies specialize in helping clients obtain data on everything from disk s hard as flash-rooms. In the following report, we will discuss what really is the recovery of data, different types, costs, and what you can realistically expect when it comes to getting your data recovery.

What to do in case of data loss?

About 44% of total data loss is caused by a hardware failure. It is important to ensure that your system immediately shut down if you suspect the hard drive has crashed. Do not even try to go through the shutdown procedure, pull the plug from the wall. Do not try to run a commercial software or data recovery utility unit. Many times these applications will assume the unit is functioning properly and increase the risk of permanent data loss.

Types of failure of disk drive

When we talk about data recovery in this report, which will focus primarily on issues related to the failure of disk drive, as these types of errors are more common. In fact, there are two primary forms of failure in a unit of disk drive, logical and physical. Logical failures are usually the result of file system corruption. This can occur due to a virus, accidental deletion of files or registry key components, and in some cases even electrostatic discharge. In most cases where a logical failure has occurred, the drive is still recognized by the system BIOS, but will not start. In most cases, your data should still be intact on the drive, although it may seem inaccessible.

If the system BIOS does not detect the presence of the unit of disk drive, then chances are a physical failure has occurred. Physical failures that can make a variety of causes. In fact, there are two sub-categories of failures disk drive physical mechanical and electronic. Mechanical failures are usually due to a failure of the spindle motor. The spindle motor failure can result from excessive heat due to bearing failure. The increased heat resulting from not having expanded the drive shaft and therefore seize the spindle motor. Suddenly, the unit will be inoperative. Occasionally, you will receive a warning that something bad is about to happen. You can hear the cry of a strong, chirp, even shrill cries. If something like this starts to occur, BACK UP YOUR DATA IMMEDIATELY.

Another physical issue that sometimes rears its ugly head is an electronic failure. If you look at a hard drive you will notice a circuit board in the bottom. This board is basically the brain of the unit, and is where the equipment is interconnected with the disk drive. An electrical failure can occur unexpectedly at any time. Even the brand of disk s hard s new is not totally immune to having electrical failures. Sometimes it’s just a faulty component; sometimes it’s improper installation (i.e. electro-static discharge, grounding to the board, damaging circuitry during installation). It is also important to keep your system clean and well ventilated, since excessive heat can damage the electrical components of the unit. If you have a system that is in a somewhat contained area, you can look at adding an additional 80mm fan to cool the internal components of the system, especially the hard drive. No other component of a computer works on both the hard drive, and therefore it is vitally important not to overlook when cooling issues arise.

How is my data recovered?

One of the most common questions that customers ask is: “how to get my data?” Well, actually not black magic or rocket science. It’s just a matter of having the right tools and knowledge necessary to know what to do as a surgeon performing heart surgery bypass. Many data recovery facilities have highlighted a variety of hardware, software and data recovery tools.

Generally speaking when a hard drive is received by a data recovery company, the first thing they do is evaluate it and determine what recovery solution will be necessary. If the drive failure is a logical issue as mentioned above, then an analysis of the unit carried out to try to repair the damage to the file system. Sometimes a partition can be repaired and the replacement drives in the state it was before the failure. If this is not possible, a very low level scan will be performed that essentially searches every sector of the hard drive files. Once the files are, then you can copy the media of choice, i.e. a CD-ROM, DVD-ROM or another hard drive. Logical recoveries can access an enormous amount of time, especially if the unit is on the verge of physical failure. It is not unusual to allow a day of exploring and one day of recovery of the files found.

f the unit has suffered a physical failure, then the recovery procedure is considerably more difficult. As mentioned above, there are actually two sub-categories of physical failure, mechanical and electronic. An important element in recovering data from a physical failure has the pieces necessary to get the unit working again. Unfortunately, with unit’s hard drive if you have a 20 GB hard drive Maxtor, for example, then you will need another identical 20GB Maxtor hard drive to recover the pieces. In cases where the electronic circuit board has failed in the disk drive, then you have to have the exact same circuit board on hand to retrieve the necessary circuit components for replacement. Often can not even exchange circuit board circuit board. These repairs generally require soldering skills and a deep knowledge of electronics out successfully. The most likely hear “class100 Clean Room” thrown around a lot when talking to data recovery professionals. In short, a class100 Clean Room maintains exceptional air purity, and contains less than 100 airborne particles over 0.5 microns in each cubic foot of air. This is vital in protecting sensitive internal components of disk s hard s. Each time a unit of disk drive is having an invasive procedure performed on it, class100 a clean room or better is required.

The time frame for recovery is generally 5-10 business days for physical issues and 2-4 days for logical issues. Sometimes if components are not available, then it may take weeks to complete recovery. Some firms offer expedites service and will definitely pay for this increased attention.
