RAID Data Recovery Advice

We recommend in all cases of data loss to leave your RAID unplugged. This will prevent further damage. Sometimes data loss can be distressing. You can call our super friendly hotline for advice on 1300 001 211. We will be able to provide you with reassuring advice on what to do next.

Avoid unqualified technicians or internet suggestions. Most of the these people have good intentions to help you but their unqualified advice usually leads to highly risky experiments and further data loss.

Leave all drives in their original locations with original cables. Do not change any settings. A RAID should be backed up before changing hard drives as the increased load to rebuild an array can cause secondary failures.


How to recover data from a failed RAID

Our data recovery lab will diagnose the problem with your NAS, SAN or RAID first. We provide a FREE test & quote. Our pricing is the lowest price guaranteed. As Australia's leading data recovery service we will then have an action plan to get your files back. Each hard drive in an array will get individually tested. Hard drives can be SATA or SAS. We keep a sophisticated journal of all server controllers and parameters for speedy recoveries.

The Most Common Causes of RAID Failure
  1. RAID device not recognized data recoveryRAID Device is not detected

    We get data back from RAIDs that are not detected by your pc, computer or mac: A RAID that has malfunctioned will not detect in any computer. Sometimes it may still make a chime sound or freeze your computer. Don't worry come and visit one of our RAID data recovery service locations and we can help. RAID device not recognized. Sometimes it will still making the connecting sound but isn't recognized.






  2. Getting data back from a clicking sas raid hard driveClicking or buzzing sounds

    We get data back from corrupted RAID drives: If your RAID drive has been corrupted it will no longer detect by your computer. Data corruption is common for a RAID stick when it has been interupted during a read and write cycle. Examples are when its not ejected properly or quickly removed or unplugged during a saving process. The next time the RAID stick is plugged back in it will no longer show the folders or files. Common error messages includes, The disk you inserted was not readable by this computer.





  3. the server controller menu shows that the raid is degradedFailed or Degraded RAID Volume

    We get data back from broken RAID drives: RAID flash drives can be bent or physically damaged. We see broken RAID connectors and fractured pcb boards. As long as the memory chip isn't damaged there is a very high chance of successful data recovery. Zero Alpha data recovery performing a chip off data recovery case. Here you can see a single 32GB memory chip that was removed from a physically broken RAID flash drive. We can directly read the data and return it to customers:





  4. Zero Alpha data recovery getting files back from deleted RAIDDeleted Files or Folders

    We get deleted data back from RAID flash sticks: When data is deleted computers remove the indexing to the files so that the RAID space becomes available for new data. Zero Alpha can find these files giving you a high success rate for deleted file data recovery also known as undeletion.








  5. how raid parity data recovery works over multiple hard drives

    Drive freezes, becomes unresponsive or is slow

    We get data back from the Insert disk error: The please insert a disk into RAID Drive occurs when their is a fault with your RAID drive. Our data recovery services are well experienced with solving this problem. If you see this message its best to leave your RAID stick unplugged and take it to us for a free evaluation. You need to format the disk in drive, error message: If you see this message its very important you don't click on format as this will cause further damage to the files on your RAID stick. Just unplug it and visit us for further advice. In most cases we can get your files back.




  6. data recovery from a RAID which asks to be formattedYou need to format the disk in drive D: before you can use it. Do you want to format it?

    We get data back from the format the disk in drive error: Its very important that you do not format disk if you see this error as it will overwrite your existing data making it harder to recover. Don't panic if you see this error as its very common and we have a high success rate.

WARNING: FOR MAXIMUM SUCCESS DO NOT UNDER ANY CIRCUMSTANCES RUN EXPERIMENTS ON YOUR RAID SYSTEM. LEAVE ALL DRIVES IN THEIR ORIGINAL LOCATIONS WITH ORIGINAL CABLES. DO NOT CHANGE ANY SETTINGS. CHANGING SETTINGS WILL LEAD TO FURTHER DAMAGE. THE RAID SYSTEM AND DRIVES MUST BE LEFT IN THEIR ORIGINAL CONDITION. IF YOU NEED ASSISTANCE ITS BEST NOT TO PANIC AND CALL ZERO ALPHA FOR ADVICE FIRST. 

DO NOT LET A AMATEUR DESTROY YOUR DATA OR RAID SYSTEM

RAID failure usually occurs when an individual hard drive has failed in the array. When replacing a single failed hard drive there is a high chance that a second drive can fail during the rebuild as this process puts increased stress on the system. So always back up data on the raid while you have the opportunity before you commit to drive replacements. Other raid problems occur when the raid controller itself fails. When this occurs the raid volume is no longer accessible. If this is a case, give our Brisbane data recovery office a call and we will help you out.

How to recover data from failed RAID or NAS

Our Brisbane data recovery lab will assess the health of the drives first. We will determine which physical hard drives have failed. Hard Drives can be SATA or SAS. Once we know the condition of each hard drive. We will determine which RAID version and controller is in use. As Brisbane's leading RAID recovery service we will then have an action plan to get your files back.

Brisbane data recovery technician uses software to virtually create a failed raid drive

In this image you can see a Zero Alpha data recovery technician re-create a virtual version of an 8 drive raid array without the original computer. Removing drives from the raid system should only be done by our staff. Interfering with a raid array can make a successful recover harder to achieve. If your raid service has failed its best to leave it off and bring the complete unit to our Brisbane store. Please leave your drives alone. Our data recovery expert will need to identify the drive order and parameters of the raid. Raid parameters can vary with manufacturers. Our data recovery engineer is highly skilled and experienced at reverse engineering these different algorithmic parameters. RAID is like reassembling a giant mathematical jigsaw puzzle. We will also rescue the data off any failed hard drives. We now have everything we need to save data to new media. This process is also known as destriping in the RAID engineering world.

Network attached storage RAID data recovery

A NAS system which is short for network attached storage is a device that uses RAID and multiple drives to store and share data over a network with multiple computers or laptops. These systems are very popular for home and business computers. They can offer similar performance to a professional raid server. Because they also use RAID technology they experience the same failures. NAS systems usually have 2 ~ 4 drives and can be RAID version 0, 1, 5, 6 & 10. The same principles apply to get data and files from a non function NAS box.

The 5 Most Common Causes of RAID Failure

1. Failure of the RAID controller

RAID controller is a hardware device or software program used to manage hard disk drives (HDD) in a computer or storage array so they work as a logical unit. The raid controller can fail, due to power surges, end of life or firmware corruption. This can cause boot problems corresponding with LED error lights or no activity at all.

2. Multiple Disk Failure

The purpose of most RAID systems is to allow the server to survive the failure of a single system disk. However its not uncommon for multiple drives to fail within a similar time frame. Drives are usually fitted to the RAID or NAS server from the same manufactured batch. RAID hard drives live a hot and hard life with little rest or maintenance. A failed disk in the system makes the array much more vulnerable to further disk failures and can result in a complete system breakdown. 

3. Degraded RAID Array

If a single disk drive fails the RAID can change status from online to offline or degraded. Backing up data is the first step you should take before replacing a failed drive. Continuing to run your system in degraded mode significantly increases the chances that the array will fail, taking your important files data with it. As the rebuild phase puts a lot of stress on the raid array and we see a lot of failures occur during the RAID rebuild phase. 

4. Server Crash

Failure of the host server for any reason can render an array inaccessible. A lot of raid computers may have a log or reporting interface to tell you what went wrong. Usually red or yellow LED lights flash indicating which drives are no longer accessible. Green and blue LED lights indicate that the drives are functioning ok and are accessible. If the RAID computer server is not booting we can simply remove the drives and re-create the raid server in a virtual environment to recover data.

5. Missing RAID Array Partitions

RAID data structured are organised by hidden settings we call RAID parameters. RAID parameters are responsible for directing the behind the scenes data blocks used to store your data over multiple disks. If this information gets damaged or goes missing the whole raid system will vanish. The partition disks can be corrupted and stop working, causing missing or unusable partitions.

What to do when you Experience a RAID Array Failure

1. Stop using the RAID

When you experience a RAID array failure, it's important that you take the right steps to protect your data. The first thing you should do is turn off the array immediately. The more you run an array in degraded mode, the more likely you are to do further damage. Just leave it off and call us for advice first.

2. Leave the drives in their original bays with original cables

A common experiment unqualified computer shops or technician's make is to try swapping the drives around. This is one of the worst things you can do. If you swap drives out of their original order then the RAID server will start writing data to the wrong drives causing permanent data loss.

3. RAID data recovery should only be performed read only

There is absolutely no reason ever to try changing system settings or worst yet, creating a new raid array to get files back. It doesn't work and makes data recovery harder than it should be.

4. Do-it-yourself data recovery

Repairing a failed disk requires a clean room environment and special tools from disk drive manufactures otherwise the dust in normal atmospheric air can do irreparable damage to the affected disk, and possibly erase your data permanently.

5. Speak to the experts!

Contact our data recovery specialist who have the tools and facilities to properly repair the system in order to retrieve your files. The likelihood of recovering your data varies depending on the cause and severity of the problem, but in most cases, data can be recovered from RAID array failures with professional assistance. If possible, make notes of the events that led to the array failure, including any unusual noises, reductions in processing speed, and any power surges or other physical events that could have damaged the array. Any information you can give your data recovery technician in Brisbane will help improve and expedite the repair process.

Types of RAID Drives

SATA Hard Drives - Seagate, Western Digital, Toshiba, Hitachi. Mounted inside a Tower, Rack mount server or Blade mount server.
SAS - Seagate, Fujitsu, WD, HGST, HPE. These drives are always mounted in a tower, rack mount, or blade mount server.
SCSI Drives - Redundant these days but ocassionally we still get these raid systems in for data recovery from older computers. We have a showcase of old scsi equipment for scsi customers.

Types of RAID Arrays

RAID 0 Data Recovery - Striping - Combines multiple physical drives together to form 1 logical drive.
RAID 1 Data Recovery - Mirror - Makes an exact copy to each physical drive.
RAID 2 Data Recovery which is rarely used, stripes data at the bit (rather than block) level.
RAID 3 Data Recovery - which is rarely used, consists of byte-level striping with a dedicated parity disk.
RAID 4 Data Recovery - consists of block-level striping with a dedicated parity disk.
RAID 5 Data Recovery - consists of block-level striping with distributed parity and has redundancy for 1 drive to physically fail.
RAID 6 Data Recovery - extends RAID 5 by adding another parity block therefore giving redundancy for 2 drives to fail.
RAID 10 Data Recovery - Also known as RAID 1 + 0. is a RAID configuration that combines disk mirroring and disk striping to protect data

Also there are many non standard, propriety and variations of raid that manufacturers produce with computer software or hardware. We can identify these types of raid for data recovery in our Brisbane office.

How much does it cost to recovery data from a RAID computer?

You will need to get a free test & quote done first at our Brisbane Queensland office. However price depends on whether the raid needs a software data recovery or a hardware data recovery. Software problems occur when the raids drives are functioning OK but data has been deleted, damaged or corrupted. Hardware problems occur when drives themselves have failed. We can test your raid array and give you a quote in person.

RAID 10 Data Recovery - Also known as RAID 1 + 0. is a RAID configuration that combines disk mirroring and disk striping to protect data

Also there are many non standard, propriety and variations of raid that manufacturers produce with computer software or hardware. We can identify these types of raid for data recovery in our Sydney office.

How much does it cost to recovery data from a RAID computer?

You will need to get a free test & quote done first at our Sydney New South Wales office. However price depends on whether the raid needs a software data recovery or a hardware data recovery. Software problems occur when the raids drives are functioning OK but data has been deleted, damaged or corrupted. Hardware problems occur when drives themselves have failed. We can test your raid array and give you a quote in person.
