1. RAID 0 Data Recovery Technique

RAID 0 is a non-redundant array usually consisting of two disks. Since there is no redundancy in a RAID 0, data recovery ( RAID data recovery ) is possible only if all the member disks are available. In case of member disk failure, first, you need to image/repair the failed disk and only then try RAID 0 recovery.

RAID 0 Failure Data Recovery

Some of the failure cases which we work for data recovery from Raid 0 array are:
• Operator / Human errors.
• RAID Controller or Software failures.
• Failure of one or several RAID 0 member disks.
• Many other common reasons for the failure of standard hard disks, such as logical, as well as firmware issues or improper user handling and even viruses.
• Bad sectors on one drive, this can harm the entire array
• PCB / Circuit board level damages
• Failing R/W heads on hard drives.
• Fire / Water damaged server With these failures, it is possible to recover data from RAID 0. Firstly, the array configuration needs to be determined.

RAID 0 is mostly used in many different types of servers, external hard drives, NAS units, Snap Servers, and in certain desktop computers. For RAID Data Extraction and Recovery we require all disks from the array, and unmodified. Hard drives including PATA, SATA, SAS, SCSI / Scuzzy, SSD and SSHD drives used in RAID 0 configuration are recoverable from our expert team.
Now Data experts are highly specialized when it comes to RAID 0 Data Recovery. Our data recovery professionals have successfully retrieved data from huge RAID systems as a vital part of our Data recovery service.
Recovering data from this array configuration can be particularly tricky, due to the lack of redundancy with the configuration and the data being stripped. Don’t worry! Contact Now Data Recovery regarding your Raid 0 data loss or hard drive failure.

RAID 0 is known as the striped set without parity since it bases on the striping technique. Raid 0 is one of the most popular disk arrays of RAID data recovery. This is a non-redundant array and it is created mainly to increase system performance because N-disks array provides N times read and write speed improvement as compared to a single disk and it can be easily created using either controller (Hardware RAID 0) or operating system (Software RAID 0) .

2. RAID 1 Data Recovery Technique

RAID 1 is popular for accounting and other financial data. It is also commonly used for small database systems, enterprise servers, and home PCs where a fairly inexpensive fault tolerance is required.
When you lost precious Rain 1 data, don’t be panic and let professional Raid 1 recovery software  help you restore lost Raid 1 disk data now.
Is it possible to retrieve data from RAID 1 Server after deleting, formatting or sometimes when RAID 1 array get fails? Our Experts Answer is YES!

Being professionals in the RAID 1 Data recovery, we recover data (RAID data recovery) from both single hard disks and mirrored volumes efficiently. Now Data Engineers recover your critical files from any type of RAID 1 array/volume.

RAID 1 Data Recovery Procedure:

If you have lost data from Raid 1 array. Submit your failed drive to our company for evaluation for RAID data recovery.
Once the evaluation gets complete, we provide you with a quotation for recovery and data approximation details and estimated time to complete the recovery work.
Once you approve of the above terms, we start recovery work in our clean room lab and deliver data.

Most importantly, it can recover lost files with their original file names and storage paths – which other freeware apps cannot do.

3. RAID 5 Data Recovery Technics

RAID 5 is a redundant array usually consisting of three disks. Due to redundancy, it is possible to recover RAID5 data even with one array member disk missing; however, if you deal with multiple disk failure,first you need to image/repair disk(s) until you get at least (N-1) disks available.

Note that ZAR RAID recovery software is capable of determining lack of the disks and add a missing disk automatically in RAID data recovery.

Reasons for Raid 5 Array Failures:

• Operator / Human Errors
• RAID 5 Controller or Software Failures.
• Failure of one or several RAID 5 member disks.
• Failure not associated with the member disks.
• A foreign configuration of the disks or Not-Initialized status in the server.
• Many other Failures which are also common for the failure of standard hard disks, such as logical, as well as firmware issues, Bad sectors or physically damaged drives.

For all these failures, Now Data Recovery engineers show you best results to regain lost RAID data recovery. We help you in recover different types of files such as Important documents, emails, etc. whenever you run into data loss problem due to different reasons.

• Bad sectors on one drive, this can harm the entire array.
• Failing R/W heads on the hard drive.
• Environmental Failures due to overheating, water damages or natural disasters.

Raid 5 Data Recovery Procedure:

The following progress indications of our Recovery Procedure:

  • Evaluation of RAID Array by Analyzing in our Lab.
  • After the Diagnosis process, we check the RAID 5 Parity, if it needs to, we reconstruct missing RAID5 drive members.
  • After Checking the parity in the array, next we scan the member disks. In this process, the structure of the file systems and data files are identified.
  • Next, we read the sequence numbers and mark the objects as Worth Attention and read the complete array again and processed.
  • Once the process gets completes, we calculate the size of the stripes and reference tables. Here we reconstruct the complete raid array and retrieve back your data is known as RAID data recovery.

All these parameters can be determined both manually and automatically. However, if you decide to recover the RAID 5 configuration manually you should be aware that this will be a very long and tedious process which requires special technical skills.

4. RAID 6 Data Recovery Technics

RAID 6 layout utilizes two different parity functions which help a RAID 6 array survive up to double disk failure. Despite the fact that RAID 6 is perceived to be more reliable than a RAID 5, the probability of a controller failure is the same. So if your RAID6 fails, this will most likely be due to a controller failure. To recover a RAID6 from a controller failure, you need to know or recover the following parameters in RAID data recovery:• number of member disks
• disk order and which disk was the first in the array
• block size
• start offset on the member disks
• positions of each parity function
• rotation of parity functions
• an algorithm used to calculate the second parity function
• the pattern of parity functions[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]

Raid 6 Data Recovery Recent Success

The recent success of data recovery from RAID 6 Server, SAS type hard drive of 1 TB each, the total server capacity of 12 TB with 3 hard drive failures. Recovery went successful without losing a single bit of information.

The client had power fluctuation for about 2 days of time and the server restarted 3 times during boot. Three drives went offline and the entire server was offline. IBM engineers have replaced the faulty hard drives with the new ones and tried to run the server but due to the failure of more than 2 hard drives, the RAID 6 cannot be completed or rebuilt with new hard drives. Our engineers visited the place for onsite analysis and later found that the drives have issues in detection and the motor rotation does not initialize.
Our engineers have acquired the hard drives and recovery process continued in our lab. The drives had firmware and the circuit board related issues wherein the firmware is the software code which controls the drive working condition, the capacity of each faulty drives has been converted into Zero MB capacity. After successfully imaging the 3 faulty drives and rebuilding in our servers, we have completed the recovery without loss of any data. The recovery was successful 100%. The client was happy to see the entire server online without installing his operating system on the same for RAID data recovery.

5. RAID Data Recovery for MAC User – Drobo Recovery

Data Rescue file recovery and many Mac users use Data Rescue to recover them. His particular problem seemed to have something else at the heart of the matter. Time for some low-level, technical support guru investigating!
After enquiring, I found out that the .mov files were inside of a hard drive enclosure that had two drives in a RAID array. In fact, the user had no idea that he had a RAID configuration and was surprised to learn that this was the issue preventing a successful scan. It turns out that he was running a scan on the individual drives separately when the files were actually spread across the two drives.
I told him that Data Rescue has the capability to recover from the two drives attached to the Mac in a RAID array. Here’s how:
If the RAID array is still intact, you should see it as a single hard drive within the “Select Drive” screen of the software. If so, you will not need to set up special parameters. You can immediately begin scanning the drive. This can be done with the standard license of the software.
However, if you are suffering from more severe data loss and your RAID array is displayed as two separate hard drives, recovery through Data Rescue is still possible, but you will need the advanced tools only included in Data Rescue Professional to reconfigure your RAID array through the software itself on RAID data recovery.

Data Rescue Supports 2 Basic Types Of RAID

Stripe – This is also known as RAID-0. As data is read sequentially from the RAID set, it comes first from the first component drive until a stripe-sized amount has been read, then the next data comes from the second component drive, and so on, in a round-robin fashion.
JBOD – This is not an official RAID level, but rather a way to make multiple hard drives appear as one big drive by concatenating them together. As data is read sequentially from the RAID set, it comes first from the first component drive, until the end of that drive is reached, then continues coming from the second component drive, and so on until the end of the last component drive.
New in Data Rescue 5 is the Auto-Detect button, which will enumerate through each supported RAID type and common stripe sizes (if applicable) and performs a quick scan with each configuration. If files are discovered through the scan, then that configuration state is saved. When completed, a list of states discovered will be presented and a result can be chosen in RAID data recovery.
Once the RAID set has been added, it can be selected to scan for data. In some cases, data may not be opened properly when recovered if the drives are not arranged in the correct order.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]

Add Your RAID To Data Rescue

The Add Virtual RAID in Data Rescue Professional allows you to simulate a RAID configuration based on the RAID functionality built into Mac OS. This is helpful in case a RAID configuration fails to mount or be recognized as a single volume.
In order to input your RAID configuration into Data Rescue, you will need to know how your RAID was originally set up; and how large the stripe size would be.
Once the RAID array has been added, it can be selected to scan for data. In some cases, data may not open properly when recovered because the hard drives were not arranged in the correct order. It is imperative that you select the RAID members in the correct order for the best results on RAID data recovery.

To simulate RAID configurations in Data Rescue Professional, please follow these steps:

  1. If you are not already in the Professional Mode of the software, go to the View → Switch to Professional Mode from the drop-down menu option.
  2. Click on the Add Virtual RAID icon at the top of the window.
  3. When the window opens, the Available Drives list shows all drives that Data Rescue can access. Select one or more drives and click Add to append them to the RAID Members list.
  4. Once a drive is added to the list it can be removed via the Remove button, or its position altered via the Move Up and Move Down buttons.
  5. Select the configuration type and stripe size, if applicable.
  6. Once the RAID set has been added, it can be selected to scan for data. In some cases, data may not be opened properly when recovered if the drives are not arranged in the correct order.

6. Linux Raid Data Recovery Technics

RAID Data Recovery is the process of rescuing and handling the data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media such as internal or external hard disk drives, SSD, USB flash drive, CDs, DVDs, RAID and other electronics. Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system (OS).
The most common reason for data recovery is the failure of an operating system. When a system fails to boot then we need to save or recover important data[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_single_image image=”138185″ img_size=”full” alignment=”center” style=”vc_box_shadow_3d” css_animation=”bounceIn”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]Linux  extends the family of powerful and cost-effective data recovery from R-TT to the Linux operating system. Linux’s flexible parameters and customizable settings, users get absolute control over their data recovery tasks. For Linux recovers data from logical disks and partitions as well as disks and partitions that have been re-formatted, damaged or deleted. In addition to disks with common Linux file systems, For Linux recovers files from Windows, FreeBSD/OpenBSD/NetBSD/Solaris, and Macintosh formatted disks. Moreover, raw file recovery (scan for known file types) can be used for heavily damaged or unknown file systems. RAID data Recovered files can be saved to disks with any file system supported by the Linux kernel (i.e. ext2, ext3, FAT, NTFS).
• Deleted from the computer and emptied from the Trash
• Corrupted due to a virus, power failure or sudden shutdown
• From disks that have been Re-formatted to the same file system or a different file system
• Damaged and have bad sectors for Linux creates an image of the entire disk and recovers it from there to prevent further physical damage to the disk

7. Troubleshooting Your RAID Recovery

If data is not being recovered properly from the RAID , we suggest the following steps to troubleshoot the issue

  • If you are running on a Mac, you will want to adjust the Allocation Block layout and re-attempt the recovery until all options are exhausted or the files are recovered. When you open the Allocation Block layout in the View tab you may see multiple options to select from. What this is doing is telling the software to start reading the data from a specific location of the drive. Depending on your setup, you may see only a single option or multiple options to select from the Allocation Tab.
