RAID Data Recovery
Managing and Preventing Hard Drive / Raid Server Failure
The failure of a hard disk can constitute a catastrophe of immeasurable proportions. The data lost can be priceless. Recovery of some or all of the data is possible via professional intervention, in many cases. Furthermore, prevention of further failures and subsequent data loss is essential thereafter.
How Hard Drives Break
A number of conditions can contribute the failure of a hard drive. Normal continued use can cause a hard drive to eventually fail. An outside factor such as major physical impacts, magnetic interference or exposure to water or fire may also cause damage to drive rendering it unusable.
The hard drive’s platter may become damaged in situations where the read and write head comes into contact with the platter during an impact. It may scratch the surface or otherwise damage it, causing bad sectors. Other hardware components of the device such as the air filter may fail, which can result in the drive becoming damaged.
How the Data is Recovered
In the event of a hard drive failure, it is best to consult a professional to assist you with the recovery of the drive and the data it contains. In some cases, the drive itself can be repaired for future use. In other (most) cases, the hard drive will be replaced but some or all of the data may be recoverable in many instances.
Attempting to repair or recover data from your own hard drive runs the risk of causing further damage. It may even cause the disk to become entirely unusable and unrecoverable thereafter. You will want to consult a qualified professional for this task. RAID data recovery can also be accomplished via a specialist.
How Further Data Loss and Hard Drive Failure Issues Can Be Prevented
Raid stands for “redundant array of inexpensive disks.” The advantage of having the drives bundled is to keep data safe in the event one of the drives in the array happens to fail for one reason or another. The same data is placed redundantly on onto more than one hard disk simultaneously.
Performance is greatly improved because the overlap of operations of input/output (I/O) is managed in a balanced manner. The MTBF (mean time between failures) is extended via RAID which improves fault tolerance.
In the event a RAID setup fails in any way, you can request a professional who specializes in hard drive recovery to perform any of the following:
- RAID 0 data recovery
- RAID 1 data recovery
- RAID 5 data recovery
- RAID 10 data recovery
Which type of RAID you have may dictate which type of recovery operation is conducted.
