  • RAID 0 Data Recovery

    RAID-0-1-Data-Recovery RAID 0 or (striping) is meant for performance and not redundancy: RAID 0 works by splitting the workload between 2 or more hard drives into stripes. It reads and writes to each drive simultaneously resulting in much faster performance and access times. However, unlike other types of RAID, RAID 0 does not provide any redundancy.

    That being said, if only one drive in the RAID 0 array fails then the entire array fails. Any failed drive must then be repaired and the RAID rebuilt manually in order to recover the data. It’s common that we receive RAID 0 arrays in for recovery when a RAID array was setup incorrectly for a small business that thought they were using a RAID 1 (mirror) instead. These RAID configurations are also very common in NAS units like the Western Digital MyBook.

  • RAID 1 Data Recovery

    RAID-0-1-Data-Recovery RAID 1 or (mirroring) is meant for redundancy not performance: An even number of drives are needed for this configuration since the drives are mirrored onto each other for the purpose of redundancy. If you have 2 drives in your RAID 1 array and one drive fails your data is still safe on the other drive.

    When most people hear the word RAID they imagine this type of array and think they are now bulletproof against data loss. The main reason they end up needing data recovery is due to the fact that the RAID goes unmonitored allowing multiple drives to fail. A perfect example is a 2 drive RAID 1 array where 1 of the drives failed quite some time ago and goes unnoticed allowing time for the second drive to fail which results in catastrophe.

    RAID 5 is very common in the PowerEdge servers.

  • RAID 5 Data Recovery

    RAID-5-Data-Recovery RAID 5 is the most common array we receive for data recovery: RAID 5 is more complex than the more basic RAID configurations. Usually RAID 5 contains four drives of equal capacity. All four drives are written to simultaneously with the capacity of only three of them combined. This has good performance benefits when it comes to reading, however write speeds are slow because it has to figure out which drives to write the parity to. It also has fault tolerance because parity is written to each drive so it can tolerate one drive failure without data loss.

    Although RAID 5 has many benefits with performance and it can tolerate a single drive failure, a second drive failure will bring the entire array down. This is the most common type of RAID we receive from businesses. The main reason they fail is because of two drive failures. Most companies don’t notice when the first drive fails and this leaves the RAID 5 vulnerable since it can only tolerate one drive failure and not two.

    RAID 5 data recovery can be very difficult since every failed drive needs to first be repaired. The correct order is needed, block size, offset, and which drive failed first must be determined with hex.

  • RAID 6 Data Recovery

    RAID-6-Data-Recovery RAID 6 “an extension of RAID 5″: Theoretically RAID 6 can support the loss of 2 drive failures and still be recoverable. RAID 6 provides additional fault tolerance by using a second parity process. RAID 6 is also much more complex than RAID 5 because it has no common standard and with two parity functions there could be several layout variations. Even though RAID 6 should be recoverable with two disks missing, sometimes only one disk can be missing or even none at all depending on which controller hardware is used.

    RAID 6 is fundamentally similar to RAID 5 as both stripe data across member hard drives with a distributed parity block. This parity block allows the RAID to reconstruct data after a single hard drive failure. RAID 6 adds a second parity stripe, which provides improved redundancy for the system.

    RAID 6 failures usually occur from a controller or server failure but two drives failing can bring down the array as well.

    RAID 6 data recovery can be very difficult since every failed drive needs to first be repaired. The correct order is needed, block size, offset, and which drive failed first must be determined with hex.

  • RAID 10 Data Recovery

    RAID-10-Data-Recovery RAID 10 “the striped mirror”: RAID 10 is a combination of RAID 0 and RAID 1. It has many benefits because you are achieving the performance of RAID 0 with the redundancy of RAID 1. In the image above you see a perfect exempt of how a RAID 10 array is configured. Disk 1 and Disk 2 are mirrored and then striped with Disk 3 and Disk 4. This provides performance and redundancy.

    RAID 10 can even support multiple drive failures as long as they aren’t on the same stripe. The only downside would be cost.

    RAID 10 data recovery can be very difficult since every failed drive needs to first be repaired. The correct order is needed, block size, offset, and which drive failed first must be determined with hex.

  • RAID 0+1 Data Recovery

    RAID-Data-Recovery RAID 01 “the mirror of stripes”: RAID 01 is another combination of RAID 0 and RAID 1 similar to RAID 10. It has many benefits because you are achieving the performance of RAID 0 with the redundancy of RAID 1. In the image above you see a perfect exempt of how a RAID 01 array is configured. Disk 1 and Disk 2 are striped and then mirrored with Disk 3 and Disk 4. This provides performance and redundancy.

    RAID 01 can even support multiple drive failures as long as they aren’t on the same mirror. The only downside would be the cost of disks.

    RAID 01 data recovery can be very difficult since every failed drive needs to first be repaired. The correct order is needed, block size, offset, and which drive failed first must be determined with hex.

  • RAID 50 Data Recovery

    RAID-50-Data-Recovery RAID 5 striping: RAID 50 is a solid choice for your RAID array. It combines the performance of RAID 5 to be striped increasing performance and capacity without adding disks to each RAID 5 array. The great thing about RAID 50 is you will still get the redundancy in each RAID set as only one drive is needed for parity, no matter the amount of disks you choose to use the each array. This is great for performance and disk space, but remember it only allows one drive failure. The more drives you have in the array the more risk you are at disk failures if not properly monitored.

    Although RAID 50 has many benefits with performance and it can tolerate a single drive failure in each array, a second drive failure will bring the entire array down.

    RAID 50 data recovery can be very difficult since every failed drive needs to first be repaired. The correct order is needed, block size, offset, and which drive failed first must be determined with hex.

  • SAN Data Recovery

    SANS-Data-Recovery (Storage Area Network): A storage area network (SAN) is any high-performance network whose primary purpose is to enable storage devices to communicate with computer systems and with each other by allowing universal connectivity between all different types of devices and computers. SAN configurations are mostly used with IBM, SUN, HP, and DELL in enterprise environments.

    A storage area network (SAN) is often more expensive than a straightforward NAS, but offers better speed and usability advantages thanks to its block-level access (as opposed to a NAS’s file-level access). When coupled with a RAID array, a SAN can provide several levels of redundancy, greatly reducing the possibility of data loss.

    Because SAN incorporates many different devices like RAID arrays, NAS boxes and Servers if a particular storage device fails then it would affect the entire storage environment.

  • NAS Data Recovery

    NAS-Data-Recovery NAS (Network-Attached Storage) RAID Data Recovery: NAS units are nothing more than file servers that provide a shared location for your data spread out over your local area network. They can be simple 2 drive Western Digital MyBook Live Duo units, or more complex 8 bay Thecus, or Synology rackmount servers.

    It’s very common for NAS units to use RAID 0, 1, or 5 arrays. Depending on how you configured your NAS it may only be able to tolerate one drive failure or even none at all.

    Because NAS can be configured in so many different ways with many different RAID configurations recovery can be very complex. NAS systems vary in size and complexity, data recovery companies need extensive experience with various configurations in order to provide results.

  • Western Digital Data Recovery

    Western-Digita-Data-Recovery Western Digital NAS RAID Data Recovery: NAS units are nothing more than file servers that provide a shared location for your data spread out over your local area network. They can be simple 2 drive Western Digital MyBook Live Duo units, or more complex 4 drive Western Digital Sentinel DX-4000 storage servers configured in RAID 5.

    Western Digital NAS units are normally configured in RAID 0, 1, or 5 arrays. Depending on how you configured your NAS it may only be able to tolerate one drive failure or even none at all.

    Because Western Digital NAS units can be configured using different RAID arrays they could become very complex to recover.

    ProtechData Recovery has successfully recovered from many Western Digital RAID configurations.

  • BUFFALO Data Recovery

    Buffalo-NAS--Data-Recovery Buffalo NAS RAID Data Recovery: Buffalo NAS units are nothing more than file servers that provide a shared location for your data spread out over your local area network. They can be a simple 2 drive Buffalo LinkStation with RAID levels limited by RAID0/1/5/10. Buffalo LinkStations are designed more for the home user. They could also be complex like a 12 drive Buffalo TeraStation configured with any type of RAID. Buffalo TeraStations are designed more for business.

    Because Buffalo NAS units can be configured using different RAID arrays they could become very complex to recover.

    Protech Data Recovery has successfully recovered from many Buffalo configurations.

  • IBM Data Recovery

    IBM-Data-Recovery IBM RAID Data Recovery: Protech Data Recovery specializes in all types of IBM series and Lenovo servers. We have experience with all types of drives and RAID configurations that IBM uses like SCSI, SAS, SATA, and EIDE hard drives.

    We receive RAID arrays from IBM X Series servers frequently and have much success in recovering data from these types of arrays.

We have experience with all types of drives and RAID configurations that HP uses like SCSI, SAS, SATA, and EIDE hard drives. We have experience with all different arrays used with HP Smart Array controllers.

    RAID 5 is very common in the Proliant servers.

  • Dell Data Recovery

    Dell-Data-Recovery DELL Servers: We are experts at recovering from DELL servers and RAID arrays. Dell is by far the most common server we encounter and have become very familiar with their RAID configurations. Most PowerEdge servers use PERC controllers configured with RAID 5 using SAS or SATA hard drives.

    • DELL PowerEdge Series
    • DELL XPS and Precision Series
    • DELL PowerVault Series

    RAID 5 is very common in the PowerEdge servers.

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.

Be sure when removing the drives to label them in the correct order when preparing to ship them out. This saves us time when virtually rebuilding the array. Find out what time of RAID array you were using, what kind of server, what filesystem, and operating system. If possible which drives are bad, and which drive failed last.

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

While most all data recovery companies don’t offer a free diagnostic when receiving the RAID because of the many hours involved, we offer our ONE RATE fees for RAID data recovery. A RAID recovery specialist will gather information from you over the phone to give you a general idea of what you can expect. Even though RAID recovery falls under our ONE RATE fees, the cost will fluctuate base on the possibilities. Our ONE RATE fee structure will by far beat any price out there. Please call us before attempting to repair the RAID yourself which could end up destroying it.

What You Can Expect during your RAID Data Recovery Process:

  • You will be assigned a personal service representative for your project who will guide you through the process.
  • The data recovery process can take 7 to 10 business days based on many factors, see below.
  • The assigned service representative will be in daily communication with the data recovery technician working on your case and keep you up-to-date with the recovery progress.

How Long Does RAID Recovery Take?

One of the first questions we get asked by most customers is “How long will the recovery take?”. Unfortunately there is no clear cut answer to that question, as each case is different. Many arrays can be rebuilt in only a day or two. However here are some factors to consider that may affect the overall time frame of the data recovery.

Hardware Condition – A drive that is fully functional is much faster to recover data from than one that is severely damaged and must be repaired. So cases that are simply related to accidental deletion, format, viruses, etc. are generally pretty quick on the turnaround. Usually within 24 to 48 hours for most cases, however there are times when it takes longer. Drives needing hardware recovery generally take about 7 to 10 days, but can take longer based on other factors below.

Drive / RAID Array Size – Even if a drive is fully functional a 4Tb drive will take as much as 20 hours to perform a single scan, and a typical recovery may involve several scans to effectively find all files. Also as a professional data recovery lab, we always clone the drive first to prevent any possibility of accidents while working with the data. As a rule of thumb expect an extra day for drives larger than 500Gb or a few days for drives larger than 2Tb. Plus for very large arrays, there can be substantial time.

Number of Failed Drives – In striped RAID arrays the number of failed drives can affect the turnaround time as well. When there are multiple failures all drives must be analyzed to determine which hard drive(s) went offline first so that the correct data is used during the rebuild.

Availability of Donor Parts – For drives with hardware issues, parts are often needed to repair the drive to a semi-functional condition where the data can be successfully extracted. Some hard drive sub-models are very common and easy to find the parts from one of our vendors. However others are not. At times we may even have to spend weeks searching online and calling other data recovery labs for the specific drive or parts we need. Or we may even have to buy a donor drive from overseas and wait for it to arrive. Usually this is the longest part of the whole process for hardware level recoveries.

Functionality of Drive After Repair – Many makes of hard drives don’t take kindly to replacement parts, and don’t function anywhere near their full potential after an internal repair. As drives write magnetic data on a microscopic level, even the slightest micro variation (or micro jog) in manufacturing of parts may cause the drive to constantly have to re-read data over and over. While rare, some drives can take a month or more to extract all the data after such internal repairs.

Pricing for RAID Data Recovery?

Our RAID data recovery prices are based on the number of drives in your RAID array, drive capacity, type of drives, type of failure, file and system type. Even though RAID recovery falls under our ONE RATE fees, the cost will fluctuate base on the possibilities. Still, our prices are the best in the industry. We will match or beat any reputable data recovery company’s price for RAID data recovery, that’s our lowest price guarantee.

How Do I Get My Data Back After Recovery?

Upon completion of the recovery, you are welcome to provide your own return media. For RAID arrays, they would generally be a high capacity external hard drive. Or, if you’d prefer you can purchase a new external hard drive from us at a competitive price and we’ll copy the data to that. For very large arrays containing large amounts of data, arrangements may be necessary to copy the data onto a NAS or other enclosure with RAID functions. Please contact us for more details if you require recovery from such an array.
