What do you do if your RAID server fails?

RAID server failure is one of the most dangerous work risks you can sometimes encounter in your workplace. When you can not access data with a single click you become inefficient and powerless. Data in RAID range or volume can not be accessed for the following reasons: • One faulty RAID controller • Multiple hard drive crashes • Poor upgrade or incorrect stripping • Error with MFT mount points. • RAID controller failure or configuration change • Adding malicious hard drives • Hardware conflicts • Software corruption • Virus infections, Software and operating system upgrades In these situations, the following steps should be taken immediately to restore important files. Do not try to reboot again. This can cause serious damage to your hard drive. Do not attempt to recover data through you, friends or PC repair shops. It can cause permanent damage. • Even if you have already tried to replace the failed drive and rebuild the array, if you still do not have access to your data, do not proceed with the forced rebuild attempt. This can delete your data. RAID Data Recovery utilities and software are not designed to restore data or rebuild RAID arrays from failed hard drives. This requires specialized equipment and professional training. Switching hard drives or reordering drives in a multi-drive RAID array can result in stripping and overwriting parity. This makes it almost impossible to rebuild your RAID array and save your company's important data. The best solution is to seek professional help from professionally trained data recovery engineers. Most of the data from crashed hard drives and bad RAID servers can only be recovered by these experts. What Do Professional Data Recovery Engineers Do? Professional data recovery engineers have in-depth knowledge of specialized tools, hexes, drive structures, MFT mount points and offsets. The basic diagnosis of professional engineers determines whether each media device is accessible to their laboratory equipment. From all the data available to them from each media, they create a raw image in the new media to help analyze and assess data loss. If some media are difficult to catch, they will examine the components and closely examine its internal condition to assess the level of physical damage. Damaged parts include electronics, read / write heads, magnets, drive motors and head assembly. Raw images of the entire server media are used for logical recovery by examining low-level data areas. Determining both the exact layout of the volume, which can be extended or striped on multiple drives, is mandatory. Improvements to file system structures are determined to gain access to critical data. Servers running on multiple drives are usually "distributed" on separate media so that the file system can be repaired and the data files recovered. It may be necessary to extract data directly from one or more fragments of the destroyed image. Professional programmers in this field have developed a complete set of software tools used by data recovery engineers to analyze, destroy, recover and recover data from raw image drives on almost all operating systems. After the recovery is successfully completed and the file lists are created, the validity of the information is checked. A file recovery list will be created when your data is restored. You can verify that your important files can be retrieved. Although emergency data recovery services are also available, this process usually takes 3-5 days.
