RAID 1 Data Recovery

We offer RAID recovery solutions for any configuration of RAID arrays. Our technical ability to retrieve data from failed RAID servers and RAID level 1 disk arrays is unmatched in the data recovery industry.

RAID 1 is referred to as mirroring. Where data is mirrored or duplicated across a minimum of two hard drives in the system. Whilst offering good performance, RAID 1 mirroring does offer the highest redundancy. Should one mirror copy fail, data on the working copy can continue running the system. But the failure of both mirror copies in the array results in loss of access to the entire array.

Over the years we have recovered data from a large number of RAID 1 mirrored disks. These include both software and hardware RAID setup. Whatever the cause of RAID 1 failure, software or hardware, natural or accidental we can retrieve your data.

RAID 1 Data Loss

RAID 1 arrays can be implemented through software, where the operating system provides the underlying RAID 1 mirroring or through hardware where a dedicated RAID controller provides the RAID 1 mirrored setup. RAID 1 speed relies mostly on the performance of each RAID disk but with the benefit of very high fault tolerance, since the failure of one mirrored drive in the array will still allow the RAID 1 volumes to be accessible. This offers excellent reliability and good RAID performance and is normally used in high data availability applications.

Whether you have a software RAID 1 array or a hardware RAID 1 array, RAID 1 mirrored storage arrays can still fail preventing access to any configured volumes. RAID 1 failure can happen if the RAID array becomes damaged due to underlying software corruption affecting both mirror copies or if the hardware RAID controller fails or if both mirrored drives in the array fail due to a hard disk crash damaging the RAID setup.

Since RAID 1 provides redundancy and is fault tolerant, the possibility of data loss due to a single disk failure is much less. However when RAID 1 arrays fail it is important to isolate the problem without making any changes to any of the drives in the array. Whilst some basic testing is necessary to establish the problem, multiple RAID 1 mirrored disk failure and any corruption to the file system affecting both mirrored drives can lead to data loss.

Advanced RAID Recovery

Our data recovery specialist engineers use a combination of raw data analysis and file system analysis to establish the best source for data recovery from either mirrored drives. Using advanced RAID recovery software solutions we then emulate the disk images as a "virtual disk" from which a single virtual RAID 1 array is created. From this virtual array all configured volumes and stored user data files are located and successfully recovered.

This level of technical ability allows us to retrieve RAID 1 data files quickly and efficiently from many serious RAID storage failures. We can retrieve critical data files by reverse engineering complex problems that affect the RAID 1 partition, RAID 1 volumes and RAID 1 mirror and many other common causes of data loss. If you encounter a RAID 1 failure, don't panic, safely power down the RAID storage system and contact us anytime, 24x7 365 days a year, for expert RAID recovery advice and emergency data recovery solutions.
