subject: Raid 1 Failure And Recovery Options In India [print this page] RAID 1 uses a technology called mirroring and requires a minimum of two drives of exactly the same size. This particular type of RAID architecture writes two copies of the data simultaneously on two separate drives. If one of the drives suffers a failure or doesnt respond, the other drive will continue to function. Being high on fault tolerance, RAID 1 is quite popular for those who are not looking for great read performance. But if ever you encounter a RAID 1 failure which renders data inaccessible, there is better way than acquiring professional RAID recovery services.
RAID 1 only immune to physical failure
Though RAID 1 can be an effective solution in physical disk failure, it offers no data protection in many other circumstances. For instance, if a virus attack damages the data present on one disk of RAID 1 array, it will also end up infecting the same data on all other drives in the array simultaneously. Therefore, systems using RAID 1 as a protection against physical failure should also have a provision to maintain backup to allow data recovery in such cases. However, if a disaster strikes when there is no backup available, no need to press the panic button. Your data can be recovered safely provided you get in touch with RAID data recovery experts immediately.
Causes of RAID 1 failure
A RAID 1 array can succumb to a failure under following circumstances:
Bad sectors in RAID 1 array
Corrupt data in RAID array
MFT corruption
Accidental deletion of files
Controller failure
Firmware failure
Partition table corrupt
Power fluctuations
Virus attacks
Backup unsuccessful
Natural disasters like fire or flood
RAID 1 Recovery
Experts who are well-versed in recovering data from all types of RAID array should be trusted for this purpose. It is recommended you go for a company which has necessary and sufficient resources to perform RAID recovery. Ensure you select a company which has a clean room facility to perform invasive recovery on physically damaged hard drives.
