In many cases that eventually come before the data recovery lab,
important details of a small business, school district or organization are stored mostly in a black or silver box in a crowded room full of pedestrian fans, colored cables and small flashing lights. The box itself can say something like Buffalo DriveStation, Seagate BlackArmor, or Western Digital ShareSpace, but in any case, it tends to be the ultimate RAID-5 tool for capturing network data.
Most RAID devices are designed and built for data integrity. RAID stands for Redundant Array of Explicit Disks (or later Independent Disks). And the technology, developed at the University of California, Berkeley, allows for a re-creation of data that if one drive in the system fails, the information it contains can be reconstructed from the remaining hard drives.
Not only do RAID-5 devices provide the reliability of unwanted data,
they distribute the data in such a way that it can be read and used quickly. Depending on the hard drive technology, they are high performance machines, which provide great speed and great resistance to data loss.
But they have their limits.
Cases in data recovery labs are very diverse, but for example, suppose that the read / write headers of one of the drivers used in RAID-5 will no longer be able to detect the magnetic circles that will guide them in the sequence of data, so they click back and forth in idle. Due to the ingenious repetition of the device built into the device,
the machine can focus on moving, operating in a compromised state as it also collects failed drive data through logical analysis of the remaining drives.
Maybe some people realize that things aren’t as fast as they used to, but this situation continues for months until the second drive turns off the chip that controls their drive motor.
Now, the IT person in charge of the network is in trouble,
since no single data is accessible. In an attempt to fix the issue, a new hard drive is installed on the device, the remaining hard drive is restored, and all hard drives are removed from the device and reinstalled. Currently, the most important data for an organization is not working. It’s a terrible situation.
At the moment no one, apparently, wants to hear what is still the best solution – preventing the automatic hacking of remote data. So it’s up to the recovery lab in the hope of wishing that what was lost may be recovered.
If you are in the cold phase of cold data loss in your RAID-5 programs,
there is some practical advice, as long as it’s up to date. First of all, if your data is inaccessible, you should not create too many lists; this will not be good for anything. It will take the current state of affairs and make it permanent. Another common mistake is to push back on the internet after realizing that there are only one or three drivers for four. The RAID controller has taken these pulses offline for a reason. It may be hit by a car. If you force this call online, the data in a healthy drive may be corrupted. Worse, the file system repair services will start to see this mess and will begin to “fix” all the latest data. The result is that the most sensitive data for healthy drivers will go away. The best thing to do is if your RAID-5 fails to return to that room with flashing lights and colorful cables and call a recovery lab.
In a few of the top data labs in the country,
engineers and computer scientists have developed methods for cases of RAID. Successful RAID-5 recovery relies on re-collecting the logical structure of the file system, which is necessary to get logical data back from a failed RAID device.
In the example above, after changing the injured / reading heads of the injured and separating them to read the plates, they would create complete binary copies of all the drivers in the system. They look at each drive individually
