Let us consider software RAID array recovery.
Main method of data recovery from a RAID array (RAID array recovery) is a data volume rebuild, i.e. by means of a software blocks from different hard drives are being arranged in the correct sequence. The order of the blocks in the array depends on the hard drives locations in the RAID and from the algorithm of the controller itself. Continue reading “RAID array recovery”
Your Hard Drive Clicking. Why? First of all, an explanation of the nature of this sound should be given. Hard Drive Clicking due to heads hitting the limiter. The reasons may be different, but most likely there are just two options: HDD is worn or defective. Continue reading “Why hard drive is clicking?”
SSD (Solid State Drive) is a drive which has no moving parts such as in a conventional hard drive. For storage memory SSD uses flash memory. In simple words, it is such a big flash stick. Continue reading “What is flash and SSD recovery?”
In the majority of logical failure cases, the drive still spins, is recognized by the BIOS, but will not boot. Recovering data from a hard disk drive with the logical failure does not require the drive repair. In this case all components of the hard drive are physically undamaged and the drive is considered as fully functional. But the data is unreadable and the operating system is not able to access some or all files, partitions, or folders. Continue reading “Logical failure – file recovery”
Quite often our experts have to perform hard disk recovery from HDD affected by large amounts of damaged unreadable sectors. Hard drive having numerous bad sectors is not able to operate properly: it slows down dramatically, it is giving various error messages including dreadful “blue screen of death”, sometimes disappears or shows unreadable volumes under “My Computer”, sometimes it makes occasional clicking sounds. This problem can affect any hard drive regardless of type, brand, model and size. Continue reading “What’s non-invasive disk recovery?”
A head crash occurs when hard drive’s read-write heads come in contact with rotating magnetic platters. Normally heads are flying over the surfaces on a thin layer of air. If this occurs the hard disk recovery is needed.And heads are not supposed to touch the rotating platters unless they are within specially designed parking area of a platter. Continue reading “How to do hard disk recovery with head issues?”
A clean room is an environment that has very low controlled levels of airborne particles specified by the number of particles per cubic meter at a specified particle size range. For example a typical urban environment contains 35,000,000 particles per cubic meter in the sCize range 0.5 micrometer and larger, while an ISO-1 clean room allows only 12 particles per cubic meter of 0.3 micrometer and smaller. Continue reading “Why clean room is important for data recovery?”
So what is “RAID recovery“?
RAID stands for Redundant Array of Independent (originally – Inexpensive) Disks. Redundancy means that the same data is stored in different places of multiple hard drives combined into a single logical unit (ironically, one of the most popular RAID configurations – RAID-0 has no redundancy). This storage technology allows to avoid data loss if one (or even more than one) of the drives fails. Continue reading “What is RAID recovery?”
Hard Drive ( “HDD“, hard disc drive) – Data storage device based on magnetic platteres and magnetism effect.
The most common form factors of hard drive are 3.5 and 2.5 inch. Continue reading “Hard drive – what is it?”
