Are You Having A RAID Failure? Do Not Panic.

If your RAID Failed due to - System Board Failures, Corrupted RAID structure, Missing Partitions, Lost Hard Disk Partitions, RAID Controller Failures or Computer Viruses.
We offer advice on how to keep your data safe after a NAS failure, SAN failure or after a file server went offline. If you are having a RAID failure, please see the information below and our RAID tips page.
We recommend you call us for RAID help or check our RAID Recovery TIPS.
Some basic RAID Recovery Tips are:
Never Run Chkdsk. Running Chkdsk on RAID will delete index data and reassign data pointers. Chkdsk destroys your RAID disk striping and your raw data. This complicates any RAID data recovery process.
Oppps - I Forgot the RAID Hard Drive Order.
When a RAID server crashes, people tend to make errors due to the stress. Losing the RAID hard drive order significantly complicates performing any RAID data recovery service. It is critical that a network administrator Check and clearly identify all RAID hard drives and associated hardware connectors.
Failure to reconnect a RAID drive properly will result in a loss of data. Take great care when trying to rebuild your RAID array. Sometimes just pulling and reseating a RAID controller card and cables can fix your downed file server, NAS or SAN.
In some cases, a RAID data recovery need not be performed. Our policy is simply to evaluate the events that lead to your RAID failure and advise the client of possible solutions.

Can A Virus Destroy RAID Data?

Our findings indicate that malicious virus attacks destroy RAID data and therefore require a RAID data recovery. RAID recovery is complicated as the virus is often copied onto the mirrored RAID 1 array.
RestoreMyData has had great success with applying our RAID data recovery tools after RAID Servers, NAS or SAN ’s have been exposed to malicious virus attacks. Utilizing the latest virus software and updates, network security and viable backup solutions are critical in achieving a stable NAS, SAN or application server environment. RestoreMyData understands the importance of every RAID 0 data recovery service and RAID JBOD recovery as this type of RAID failure has no built in RAID redundancy for RAID failure.

Why Use RAID 0 & RAID JBOD?

Increased Data storage demands have shifted from single hard drives to Redundant Array of Independent Disks (RAID) solutions. RAID is a storage scheme that allows for low-cost hard drives to be used into an array. RAID offers increased data storage capacity, reliability, speed, or combinations of speed and reliability.
Hardware or software RAID can provide data integrity, fault-tolerance, multi-cached throughput or storage capacity. RAID 0 or RAID JBOD (just a bunch of disks) allows for fast data access and larger hard drive storage space.
My RAID 0 + 1 Server Failed …Can My RAID Data Be Recovered?
RAID 0 + 1 is a viable data storage solution as RAID 0 allows for fast read / write access speeds and large hard drive support. The second RAID 1 array (second set of multiple disk drives) then serves as a backup to the RAID 0 array.

RAID 5 Failed. Do I need a RAID 5 Recovery?

A failed RAID 5 array does not require a RAID data recovery. The RAID 5 array will rebuild itself along with the data once the failed hard drive is replaced. However, a RAID 5 failure and a RAID 5 Data Recovery is not fool proof.
Our experience reveals that a RAID 5 data loss can be attributed to virus attacks, deleted partitions or multiple hard drive failures. If your RAID failure is a result of a faulty motherboard or failed RAID controller card, then there is no need to perform a RAID 5 Data Recovery Service as replacing the damaged hardware should bring the RAID back online.

How does a RAID 5 Data Recovery Work?

RAID 5 requires a minimum of three disks and enhances performance utilizing disk striping, redundancy and parity. Striping interleaves bytes or groups of bytes across multiple drives. Therefore, more than one hard drive is reading and writing simultaneously.
Parity is a calculation used in RAID to test the integrity of the data stored on another hard drive. RestoreMyData uses this parity calculation to perform the RAID 5 data recovery. Another RAID 5 Data Recovery approach incorporates repairing the parity information first, followed by the RAID Data Recovery. A bit from hard disk 1 is XOR'd (calculated) with a bit from hard drive 2. The resultant bit is identified as the parity calculation and is stored on the Hard Drive 3.

Do I need a Software RAID Recovery?

Software RAID failures can be misdiagnosed. Some Software RAID failures can result from a faulty motherboard, a crashed RAID controller card, damaged RAM or CPU. Replacing any bad components can bring your RAID back online and eliminate the need of a RAID Data Recovery Service.

Can Heat and dust destroy your RAID Server?

Built in heat can destroy hard drives, memory, CPU and cables. It is important to keep your file servers, SAN and NAS clean and cool. Maintenance is best preformed when the NAS, SAN or file server is shut down and is at normal room temperatures.
RAID Controller Failures.
RestoreMyData is experienced with many RAID recoveries using the following RAID controller cards and RAID technologies:
3ware
PERC
Adaptec
Pinnacle
AMI
Promise
Bus Logic
RAID Tec
Compaq HP
Storage Dimensions
Mylex
Sun-Software RAID
Our Recovery Guarantees
RMD´s experience and high customer satisfaction levels are why clients recommend our data recovery services.

Our online File Recovery Viewer is another example of how we strive to help clients see what data we believe is recoverable, before they buy their data recovery service.
