  • RAID 0 Data Recovery

    RAID-0-1-Data-RecoveryRAID 0 or (striping) is meant for performance and not redundancy: RAID 0 operates by dividing the task among multiple hard drives, creating stripes for reading and writing simultaneously. This leads to significantly improved performance and access times. Nonetheless, unlike other RAID configurations, RAID 0 does not offer any form of data redundancy.

    If a single drive in the RAID 0 array fails, the entire array will fail. To recover the data, the failed drive must be repaired and the RAID rebuilt manually. We often receive incorrectly configured RAID 0 arrays for recovery, particularly when small businesses mistakenly believed they were using a RAID 1 (mirror) setup. These types of RAID configurations are also frequently found in NAS units such as the Western Digital MyBook.

  • RAID 1 Data Recovery

    RAID-0-1-Data-RecoveryRAID 1 or (mirroring) is meant for redundancy not performance: This setup requires an even number of drives to ensure redundancy through mirroring. In a RAID 1 array with 2 drives, if one fails, your data remains secure on the other drive.

    The mention of RAID often conjures up images of a secure data storage system, leading people to believe that their data is impervious to loss. However, many find themselves in need of data recovery because they neglect to monitor their RAID setup, which can lead to multiple drive failures. For instance, a 2-drive RAID 1 array may have one failed drive that goes unnoticed for a long time, eventually causing the second drive to fail and resulting in a disastrous situation.

    RAID 5 is very common in the PowerEdge servers.

  • RAID 5 Data Recovery

    RAID-5-Data-RecoveryRAID 5 is the most common array we receive for data recovery: RAID 5 is a more intricate option compared to the simpler RAID setups. Typically, it consists of four drives with the same storage capacity. All four drives are written to at the same time, with the combined capacity of only three of them being utilized. This results in improved performance for reading operations, but slower write speeds due to the need to determine which drives should receive the parity data. Additionally, RAID 5 offers fault tolerance as parity information is written to each drive, enabling it to withstand a single drive failure without losing any data.

    RAID 5 offers significant performance advantages and can withstand the failure of a single drive, but if a second drive fails, the entire array will be compromised. This type of RAID is widely used by businesses, but it is particularly susceptible to failure due to dual drive failures. Often, companies are unaware of the initial drive failure, leaving the RAID 5 vulnerable as it can only withstand one drive failure rather than two.

    Recovering data from a RAID 5 system can pose significant challenges, as each failed drive must be repaired in the correct sequence. It is crucial to determine the block size, offset, and the initial failed drive using hexadecimal notation.

  • RAID 6 Data Recovery

    RAID-6-Data-RecoveryRAID 6 “an extension of RAID 5″: In theory, RAID 6 has the capability to withstand the failure of 2 drives and still be able to recover. It achieves this by employing a secondary parity process, thereby enhancing its fault tolerance. Unlike RAID 5, RAID 6 is considerably more intricate due to the absence of a universal standard and the presence of two parity functions, leading to numerous potential layout variations. Despite the expectation that RAID 6 should be recoverable with two absent disks, certain controller hardware may allow for only one missing disk or even none at all in some cases.

    RAID 6 operates in much the same way as RAID 5, with both systems distributing data across multiple hard drives and utilizing a parity block to enable data reconstruction in the event of a single drive failure. However, RAID 6 goes a step further by incorporating a second parity stripe, thereby enhancing the system’s redundancy.

    Typically, RAID 6 failures stem from a controller or server malfunction, although the array can also be compromised if two drives fail simultaneously.

    Recovering data from RAID 6 can pose significant challenges due to the requirement of repairing each failed drive before proceeding. It is essential to establish the correct sequence, determine the block size, offset, and identify the initial failed drive using hex.

  • RAID 10 Data Recovery

    RAID-10-Data-RecoveryRAID 10 “the striped mirror”: RAID 10 combines the features of RAID 0 and RAID 1, offering the performance advantages of RAID 0 along with the data redundancy of RAID 1. The diagram illustrates a typical configuration of a RAID 10 array, where Disk 1 and Disk 2 are mirrored and then striped with Disk 3 and Disk 4 to achieve both speed and fault tolerance.

    RAID 10 has the capability to withstand multiple drive failures, as long as they do not occur within the same stripe. The primary drawback is the associated cost.

    Recovering data from a RAID 10 setup can prove to be quite challenging, as each malfunctioning drive must be repaired before proceeding. It is crucial to determine the correct sequence, block size, offset, and the initial drive failure using hexadecimal code.

  • RAID 0+1 Data Recovery

    RAID-Data-RecoveryRAID 01 “the mirror of stripes”: RAID 01 combines the features of RAID 0 and RAID 1, much like RAID 10. It offers the advantage of achieving the speed of RAID 0 while also providing the data protection of RAID 1. The diagram illustrates a typical setup for a RAID 01 array, where Disk 1 and Disk 2 are striped and then mirrored with Disk 3 and Disk 4, ensuring both performance and redundancy.

    RAID 01 has the capability to withstand the failure of multiple drives, as long as they are not part of the same mirror. The main drawback would be the expense of acquiring additional disks.

    Recovering data from RAID 01 can pose significant challenges due to the requirement of repairing each failed drive before proceeding. It is crucial to accurately determine the correct sequence, block size, offset, and the initial drive failure using hexadecimal notation.

  • RAID 50 Data Recovery

    RAID-50-Data-RecoveryRAID 5 striping: RAID 50 offers a strong option for your RAID setup. By blending the speed of RAID 5 through striping, it enhances both performance and storage capacity without requiring additional disks for each RAID 5 array. What’s particularly advantageous about RAID 50 is that it maintains redundancy within each RAID set, necessitating only one drive for parity, regardless of the number of disks employed in each array. This setup is beneficial for both performance and storage, but it’s important to note that it can only tolerate a single drive failure. As the number of drives in the array increases, so does the risk of disk failures if not adequately monitored.

    RAID 50 offers significant performance advantages and can withstand the failure of a single drive in each array. However, if a second drive fails, the entire array will be compromised.

    Recovering data from a RAID 50 setup can prove to be quite challenging as each failed drive must be repaired before proceeding. It is crucial to determine the correct sequence, block size, offset, and the initial failed drive using hexadecimal notation.

  • SAN Data Recovery

What to do when your RAID fails.

  • Do not run any chkdsk options like FSCK, or CHKDSK. These utilities can corrupt or destroy your file system.
  • Do not try to rebuild the RAID array. Doing so can wipe out data needed to recover the data you are seeking.
  • Do not remove several failed drives at once hoping to reinitialize the array.
  • Do not lose the correct order of the drives in the array.
  • Do not try to repair any damaged drives yourself.

Before shipping out the drives, make sure to label them in the correct order to facilitate virtual array reconstruction and save time. Identify the RAID array type, server specifications, filesystem, and operating system used. If available, determine which drives are faulty and which one failed most recently.

**Important** We need all original disks that were in the array the last time it was operating normally.

How Long Does RAID Recovery Take?

Most customers inquire about the duration of the recovery process as one of their initial questions. Unfortunately, there is no definitive answer to this query, as each case varies. While some arrays can be reconstructed within a day or two, several factors may impact the overall timeframe of data recovery.

Hardware Condition – A fully operational drive allows for faster data recovery compared to a severely damaged one that requires repair. Cases involving accidental deletion, formatting, viruses, and similar issues typically have a quick turnaround, usually within 24 to 48 hours for most situations, although there are exceptions. Drives requiring hardware recovery usually take around 7 to 10 days, but this timeframe can be extended due to various factors.

Drive / RAID Array Size – Despite being fully operational, a 4Tb drive can take up to 20 hours to complete a single scan, and multiple scans are often necessary for a thorough recovery of all files. Our standard practice as a professional data recovery facility is to always create a clone of the drive initially to minimize the risk of any mishaps during data retrieval. Generally, it is advisable to allocate an additional day for drives exceeding 500Gb in size, or several days for those surpassing 2Tb. Furthermore, substantial time may be required for very large arrays.

Number of Failed Drives – The turnaround time in striped RAID arrays can be impacted by the quantity of failed drives. If there are multiple failures, all drives need to be examined to identify which hard drive(s) went offline first, ensuring that the accurate data is utilized during the rebuild process.

Availability of Donor Parts – When encountering hardware problems with drives, it is often necessary to obtain parts in order to restore the drive to a semi-functional state where the data can be extracted successfully. While some hard drive sub-models have readily available parts from our vendors, others are more difficult to find. In some cases, we may need to dedicate weeks to scouring the internet and contacting other data recovery facilities in search of the specific drive or parts required. Alternatively, we may need to purchase a donor drive from abroad and await its delivery. Typically, this aspect constitutes the lengthiest part of the entire process for recoveries at the hardware level.

Functionality of Drive After Repair – Numerous hard drive brands are not compatible with replacement parts and often operate well below their optimal capacity following internal repairs. Because hard drives record magnetic data at a microscopic level, even minor variations in the manufacturing of parts can lead to continuous data re-reading. Although uncommon, certain drives may require a month or longer to retrieve all the data after undergoing internal repairs.

Pricing for RAID Data Recovery?

The pricing for our RAID data recovery service is determined by factors such as the number and capacity of drives in your RAID array, the type of drives, the nature of the failure, and the file and system types. While our RAID recovery falls under a single rate fee structure, the cost may vary depending on specific circumstances. Nonetheless, we are proud to offer competitive prices that are unmatched in the industry. In fact, we guarantee to match or beat any price offered by a reputable data recovery company for RAID data recovery.

How Do I Get My Data Back After Recovery?

After the recovery process is finished, feel free to bring your own storage device for the returned data. For RAID arrays, a high-capacity external hard drive is usually recommended. Alternatively, you can buy a new external hard drive from us at a competitive price and we will transfer the data onto it. In cases of very large arrays with substantial amounts of data, special arrangements may be needed to transfer the data onto a NAS or similar storage system with RAID capabilities. If you need recovery from such an array, please get in touch with us for further information.
