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.
R3 Data Recovery is an excellent emergency data recovery service that I would have no hesitation in recommending to anyone.
From the initial telephone conversation I had with them I was extremely impressed by their implicit understanding and sensitive handling of my stress and panic, believing I had possibly lost 10 year’s worth of invaluable documentation, imagery and archiving from my highly respected research held on a USB stick.
They worked efficiently and conscientiously to retrieve data urgently for me and made provision for me to receive it and all in time for an important PP presentation, the success of which was crucial to my career.
They were mindful in keeping me informed of their progress with the recovery process, hence putting my mind at rest, and they accomplished this all within a working day/evening. They worked hard and consistently until the job was completed successfully and made themselves available for me to talk to during out-of-work hours. They transferred all the remaining data that was not urgent onto a USB stick and returned it in the post to me, thus very satisfactorily completing an exemplary and outstanding service.
