Redundancy in RAID is not infallible

We still see lots of RAID data recovery, whether hardware
failure, controller corruption or simply human error!

RAID failures explained

The theory behind the error correction in RAID assumes that failures of drives are independent. In practice, the drives are often the same age, with similar wear. Many RAID failures are due to mechanical issues which are more likely on older drives, so the chances of a second drive failure after the first, are higher than thought. Where two drives fail, this will result in data loss. Most hard drives have a quoted service life of five years.

However, users should be aware that drives are built to different levels of robustness, depending on their intended application. Enterprise-class fibre-channel and SAS drives are generally designed to withstand the heavy use in an array, but desktop-class drives are far less robust and being used in an array could shorten their life significantly. While RAID may protect against drive failure, the data is still exposed to operator, software, hardware and virus destruction.

Although RAID recovery is one of the most technically challenging types of data recovery, we are able to provide unmatched resources to make sure we can cover all the mainstream Raid levels. We also support proprietary RAID systems and have extensive experience with MAC, UNIX, FAT and VMware Raids.

The use of Virtual Machines (VM) or Virtual Machine File Systems (VMFS) has become more popular in today's enterprise world. Virtualisation is being adopted by IT professionals, businesses and organizations to divide one physical server into multiple, isolated virtual environments. Running multiple Virtual Machines on one physical server enables an efficient utilization of computer or server hardware and it is much more cost effective.

Many Data Centers also turn to Server Virtualisation and Server consolidation to reduce costs, energy consumption and space.

Virtual Machines, however, are vulnerable to much of the same issues that affecting physical machines and data loss situations are prevalent in Virtual Machines and often are even more destructive considering the consolidation of valuable data on one physical system. Calculating data parameters are complicated by the virtual file system. Our Virtual Machine Recovery Specialists can recover data from any Virtual Machine available today including VMware, Citrix / Xen, Microsoft Hyper-V, Oracle VM, Virtual Box and more.

Free Data Recovery Evaluation

"Our free hard drive data recovery evaluation service will tell you whether your data can be recovered, exactly how much it will cost and how long the data recovery will take. Simply phone or email us for a job number and send your data recovery to us. Your hard drive or media will be photographed, catalogued and bar-coded and the data recovery evaluation will start within an hour of receipt."

File Listing Of Recoverable Files

"Once in the laboratory, your media will undergo a comprehensive data recovery evaluation to determine the extent of the data loss. We aim to complete this process within 24 hours depending on the complexity of work involved. The engineers will provide a no obligation recovery prognosis, with a guaranteed list of recoverable files and an estimated timescale. You can then decide whether to proceed with the recovery. Should you choose not to proceed, we will return your media by secure data courier."

Completing the Data Recovery

"Should you choose to proceed, the data recovery process will be completed and the data will be safely stored on our servers. We will then copy out the data to your preferred choice of output media - either 64Gb memory stick or HDD (for purchase or loan). Your data will be dispatched on our secure, next day courier service. Once you have received your data any copies of your data will be permanently and securely erased from our servers after 7 days."

"I would definitely recommend them to all"

"I had an employee who kept two years worth of his work, on his local drive rather than his network drive. When the drive died the user was in a panic! I send the drive to Data Recovery Specialists, who were able to recover all the users data, promptly and at a good price too! I would recommend them to all - 5 Stars!" - Gary Mulvihill

"You guys saved my company"

"Laptop died with everything for my business on, all invoices, contacts, emails, resources and financials. One data recovery 'expert' just said "your hard drive is dead", but everything was recovered by DRS... Also, provided an extremely fast turn around for reasonable price, where other companies were asking for a significantly higher fee just to look at the computer. Literally, you guys saved my company. I can not thank you enough!!!" - Andrew Laundy

"Professional and friendly throughout"

"I am so pleased as data recovery specialists managed to recover all of my thousands of photographs which I stupidly didn't back up. Service was great and fast. The service wasn't cheap, but they kept in touch with me the entire time, and were professional and friendly throughout. And they recovered my data too!" - Claire Whalley

"I would definitely recommend them for hard drive recovery"

"What do you do when faced with a data recovery situation - I just wanted to cry. After an internet search and phoning around several companies, Data Recovery Specialists seemed to be the best solution. Even though it was a Saturday, they dealt with my enquiry and assured me they could help. I sent my hard drive to them and within a day of receipt they had already determined what was recoverable. They quote was reasonable and I am so thankful to Data Recovery Specialists. I would definitely recommend them for hard drive recovery!" - Shaun Weston

"I would definitely use them again"

"Our RAID-5 failed after two hard drives went down with mechanical issues. Data Recovery Specialists were recommended and they immediately responded to our enquiry. On reciept of the RAID hard drives they expedited the data recovery process and 24 hours later we received all the RAID data. We were expecting considerable downtime, so to be up and running again so quickly was definitely a bonus. I would definately use them again, but I am hoping we don't have any more data recovery issues!" Willmott Dixon

"Surprised how quick the data recovery was!"

"Thank you for processing our data and copying it to hard drive. We were pleasantly surprised how quick the data recovery was and you kept us informed throughout the process. Data Recovery always raises trepidation, but we found the whole experience quite reassuring. I would not hesitate to recommend Data Recovery Specialists in future." Ministry of Defence

"Fast, effective and professional data recovery"

"I thought we would never get our scans recovered and imported back onto our PACS system, but you came to our rescue. Your RAID data recovery service was fast, effective and professional and the consultants we dealt with were very knowledgeable and helpful. Brilliant data recovery service - thank you!" NHS

"Data Recovery Specialists are a real life saver"

"Thank you so much for all your help - Data Recovery Specialists are a real life saver! I do not know what I would have done without the data you recovered from our external hard drive. We would have probably had to re-record all the location shots, which would have been time consuming and very expensive." BBC Wales

"Your hard drive data recovery service really was second-to-none"

"Thank you for solving our stiction issues so promptly from our reel to reel tapes. We were expecting to lose some of the data, so we were extremely happy when you recovered the full survey. Your hard drive data recovery service really was second-to-none! The data you recovered has proved invaluable." Regal Petroleum

"They really eased my mind"

"I was so worried when I dropped my laptop. It contained all my work and stupidly, I had not backed up the hard drive! I had heard the hard drive data recovery was expensive but had no option. From my first discussion with Data Recovery Specialists, they really eased my mind and I felt confident they could do the job. And to my surprise, the quote for data recovery was not nearly as much as I had budgeted. Thanks for all your help guys! " Victoria Hall

"They really are life-savers!"

"From the moment I called Data Recovery Specialists to receiving the data, I cannot fault the service. They recovered absolutely everything from my hard drive and at a price I was comfortable with. Data Recovery Specialists really are life-savers! Whilst I hope it doesn't happen to me again, I would certainly call their data recovery team if I need to." Shenda Falvey
