Data Loss Symptoms in RAID Array / NAS, SAN, DAS & Workstations :

  • Drives and partitions are not accessible or drive mounting failure.
  • Applications fail to run & data is inaccessible or not visible.
  • Files & folders have data corruption. (Files & folders appear, but data is corrupted due to loss of configuration or error in disks).
  • Virus attack with partition loss or data loss. Software corruption,
  • Loss of Configuration & Server does not Boot after entering into BIOS Setup.
  • Rebuilding failure due to bad hard disk or damaged striping.
  • It is taking too long to rebuild configuration, indicating bad disk or damaged disk in the array.
  • Hard disk failure in component level in PCB / Electronic circuit board, damaged components or media level failure.
  • Firmware Failure with hard disk detection with model but capacity is not shown.
  • “CRC Errors” / Bad Sectors in Hard Disk or “Unrecoverable Read Errors (URE)” during the rebuild.
  • “Punctured Sectors” in Array losing configuration & after hot-swap, the configuration is not built.
  • Media Level damage in one or more Hard disk in the Array.
  • “Drive Offline” “Drive Foreign” Error, multiple drive failures in the Array structure making inaccessible.
  • Physical damage caused due to water, fire, earthquake or heavy electricity.
  • Hardware RAID Controller failure due to power outage or fluctuation & rebuilding failure.
  • Reconfiguration of Controller by accident or human error either by replacing the new drive or new configuration.
  • Accidental Partition loss either due to format, delete or mishandling.
  • Accidental file or folder loss either due to format, delete or mishandling.
  • Hardware corruption due to incompatible devices addition or hardware component conflicts.[/panel]

Precautions needs to be taken during the drive crash or RAID array parameter loss to avoid future data loss from the same.

Precautions in RAID After Data Crash / Loss:
  • Do not replace any of the drives in the array with new hard drive, until sure that remaining drives are healthy.
  • Don’t remove the drives and insert it into different slots, RAID will be configured with series on numbers starting from 0,1,2… Misplacing the drives into the different slot will lose its original array structure.
  • Do not import configuration on the controller if more than the spare capacity of drives are replaced. Ex: not more than 1 drive in RAID 5.
  • Don’t listen to the server or NAS box vendors while they concentrate on bringing the server back online not on data available inside the same. Most of the cases are damaged during initial stages yielding damaged data during recovery.
  • Retain original hard drives in the array, if the reconfiguration fails we can make use of the original array and its drives for data recovery, not to replace the drives with vendors.
  • Label each hard drive by its series, Ex: 0,1,2,3… as per the original configuration.
  • Try not to reset to factory reset in NAS box since the overwritten partition recovery in NAS will yield irregular results in its folder structure.

In all the above cases, RAID data recovery service is required, any DIY activity will damage the parameters and hence damage the workings files and folders from the drives. We handle the drives with read only parameters ensure in the original drives are intact in the same condition even after data recovery process completion, we provide the best and expert results in industry in RAID data crash.

Types of Standard RAID Recovery from Array’s :

Raid Array Array Description No. of Drives Fault Tolerance RAID Recovery
RAID 0 Block-level striping without parity or mirroring. Minimum requires 2 hard disk’s. Performance: High
Redundancy: Low
Efficiency: High
Non Fault Tolerance – A Single drive failure in array will result in total data loss. RAID 0 is Low cost & maximum performance.
Recovery for RAID 0 requires all original hard disk’s used in the same array during data loss.
RAID 1 Mirroring without parity or striping. Minimum requires 2 hard disk’s. Performance: Average
Redundancy: High
Efficiency: Low
High Fault Tolerance – Provides high fault tolerance due to copies of same data is mirrored in alternative hard disk. Capacity will be reduced to half. Provides data redundancy, high performance & fault tolerance. Costly.
Recovery for RAID 1 requires (n-1) (where n is total number of drives), drives of the original hard disk’s used in the array during data loss.
RAID 2 Bit-level striping with dedicated Hamming-code parity Minimum requires 3 hard drives. Less used Array structure. Can recover from 1 Drive failure. Recovery of RAID 2 requires (n-1) drive of original array.
RAID 3 Byte-level striping with dedicated parity. Minimum requires 3 hard drives Rarely used array, Can Tolerate from 1 drive failure. Suitable for higher transfer rates. Recovery of RAID 3 require (n-1) drive of original array.
RAID 4 Block-level striping with dedicated parity. Minimum requires 3 hard drives Fault Tolerance with 1 disk failure. Used in NetApp enterprise level company. Normally is replaced with RAID 5 structure. Recovery of RAID 4 require (n-1) drive of original array.
RAID 5 Block-level striping with distributed parity Minimum requires 3 hard drives Performance: Average
Redundancy: High
Efficiency: High
Fault Tolerance with 1 disk failure. Very Popular due to Low Cost of redundancy,
Recovery of RAID 5 require (n-1) drive of original array.
RAID 6 Block-level striping with double distributed parity. It extends RAID 5 by adding additional parity block. Minimum requires 4 hard drives Performance: Average
Redundancy: High
Efficiency: High
Fault Tolerance with 2 simultaneous disk failure. Read operation is good but performance is penalized for write operation.
Recovery of RAID 6 require (n-2) drive of original array.
RAID 10 Mirroring without parity, and block-level striping Minimum requires 4 hard drives. (Mirror + Strip) or (Strip + Mirror) Performance: Very High
Redundancy: Very High
Efficiency: Low
Fault Tolerance with 1 disk failure per span.
Recovery of RAID 10 require (n-1) drive of original array per individual span.
RAID 0-1 Mirroring with RAID 1 & Striping with RAID 0 Minimum 2 Disk for RAID 1 & 2 Disk’s per RAID 0 Array Performance: Very High
Redundancy: Very High
Efficiency: Very Low
Fault Tolerance with 1 disk failure per RAID 1
Recovery of RAID 0-1 can be done even with many drive failure with RAID 1 Drives & none in RAID 0 array

What is Raid Recovery?

  • RAID stands for Redundant Array of Independent Disks. A Group of hard drives, that forms a logical unit & work together to reduce the chance of data loss (depending on the type of configuration).

How does it work?

  • A RAID joins physical disks into a single logical unit by utilizing either uncommon hardware or programming. hardware solutions can arrive in an variety styles, from assembled onto the motherboard or add in cards, up to large enterprise NAS or SAN servers. With these setups the (OS) is unconscious of the specialized activities. Programming solutions are normally executed inside the OS.
  • It is generally utilized on servers, yet can be utilized on workstations. The latter is especially true in storage-intensive PCs, for example, those utilized for video and audio editing, where high storage capacities and data transfer speeds are required.

Does RAID data array has prone to errors?

  • Yes, But even RAID array are prone to errors and damages due to multiple drive failures, Configuration failures or human error or any other reasons.
