A recent case in a failed EMC storage array with over 40 drives confirmed that multiple disk failures can happen even in an enterprise class architecture. When a large RAID array fails it is recommended you get advice from Andy at R3, pulling and replacing drives and then allowing drives to resync may appear a normal procedure. But it is the most likely time data will be corrupted and the data be lost.
The problem stems from the fact that if one drive has failed and not been noticed then another fails just replacing the failed drives will often lead to finding a 3rd or 4th failing drive, especially in large scale environments.
The problem is the next drive to fail might only do so because of the resynching of the replacements of the first drives to fail. It is at this point it get messy and can become a full disaster recovery situation requiring data recovery.
Call to Andy at R3 for advice on a failed RAID array or SAN - his lab and team of data recovery engineers are one of the best ever assembled in the UK.
I have recently used R3D to retrieve data from an external hard drive.
I called Andy at 11pm on a Saturday after my hard drive failed, he immediately ran through the symptoms and calmed my fears that all data was lost, but was honest that data recoveries are not always successful.
I required the data immediately as it was for a deadline the following Friday, the issue was I was based in London and the lab based in Sheffield.
After searching all data companies in and around London none would answer my call on a Saturday. In fact no one else would answer my call or say they could look at my case on the Sunday.
I took the drive myself to R3D and was very impressed with their facilities. Andy also explained the whole process and what they were doing at each stage.
Unfortunately the hard drive had a physical failure and needed to be rebuilt to have any chance of recovering the information.
After starting the rebuild at 4pm on the Sunday, Andy advised it would take him and his team until the morning to know if any information was recoverable - fantastic I thought. Andy and Mark got to work on my drive as soon as I left and by 10pm on Sunday they had retrieved almost the entirety of the information of my hard drive.
I cannot reccomend R3D highly enough, they are clearly experts in their field and have a passion for what they do. Through the whole process Andy kept me informed of progress and explained everything they were doing.
