A RAID 6 recovery is not child’s play, because RAID arrays depend on multiple disks that are read and written simultaneously and data is spread out across the disks through striping, mirroring or parity.  Normally, a RAID hard disk failure is not a problem and a new hard disk simply has to be slotted into the failed disk’s space to restore parity and have the RAID re-written.  However, consecutive disk failures have been known to happen, especially where identical disks fail at a similar age and if your RAID array fails before you can replace the redundant disk.

Act Promptly

However, if you act promptly after the disk failure and a RAID 6 recovery is started, much, if not all, of your data can be recovered.  However, it is important to act at once, before data can be overwritten, files deleted or changed or data corruption can take place.  Although it is extremely unlikely that two RAID drives fail at once, you have to back up your data regularly or shut down the RAID when a drive has failed and only start it up again once the new disk has been fitted.

Different RAID Arrays

Besides RAID 6 recovery, we also perform RAID 0 to 5 recoveries; here are the main differences:

• RAID 0: not true RAID in terms of redundancy (there is none), but if offers improved performance because the data is evenly striped across two or more disks.
• RAID 1: creates exact mirrors of a set of data across two or more disks.
• RAID 2: stripes data at block level with Hamming error correction allowing for seven disks.
• RAID 3: a dedicated parity disk and byte-level striping.
• RAID 4: a dedicated parity disk and block-level striping.
• RAID 5: parity data distribution across all disks; low cost of redundancy.
• RAID 6: adds an additional parity block to RAID 5.

We can recover data from nearly all media, platforms and operating systems, so we are certainly your first choice for a RAID 6 recovery too.

Most large companies rely entirely upon databases today – more so than the majority of us realize. Databases have become so much a vital part of our lives that we take them for granted. Databases are used every day by:

• Schools and Universities in their Marks Databases
• Police for profiles of criminals, DNA and fingerprints
• Libraries, chain stores, estate agents, banks, brokers, air traffic control
• Blogs
• On line stores

The list is endless. Databases have become such a part of our daily lives that for one to fail can mean financial disaster for an organization if the data is not recovered rapidly. Quick and efficient database recovery is essential, and there are professionals like Intratec who can do this. Organizations should make regular backups of their databases or have the data stored in such a way that it can be recovered easily, by using RAID configurations, for example.

RAID stands for Redundant Array of Independent Disks, and was originally a technology that allowed computer users to achieve mainframe-class storage reliability from low-cost and less reliable PC-class disk-drive components by means of a technique of arranging the devices into arrays for redundancy. RAID is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple hard disk drives.

When multiple physical disks are set up to use RAID technology, they are said to be in a RAID array. This array distributes data across multiple disks, but the array is seen by the computer user and operating system as one single disk. Intratec Date Recovery is able to use the proper recovery protocols that are essential to prevent data loss or damage to file system structures.

Each data recovery, file recovery, undelete, RAID recovery, disk recovery or disaster recovery case begins with a free evaluation to determine the potential for recovery and to provide a firm price-quote for your review. Initial diagnosis determines whether the media is accessible to our lab equipment. If so, the first priority is to create a raw image of the data so that logical analysis can determine the nature of the data loss situation. If the media is inaccessible our lab will test the components and closely examine its internal health to determine the extent of physical damage.

Logical recovery uses the raw image by examining the low-level data sectors and determining what fixes to file system structures are needed to get access to the important data. Sometimes the existing file system structures are missing or damaged so much that data has to be extracted directly from one or more fragments of the raw image. Once a recovery has been successfully performed, file lists are created and data validity is checked.
