Netgear NAS RAID 5

Notes

NAS (Network Attached Storage) devices are very popular with businesses as they offer large quantities of storage capacity with the safety of a RAID 5 setup. Data loss on NAS systems is often caused by one of the hard drives in the NAS going faulty, but in a RAID 5 system, one drive can crash and the RAID will continue working without any data loss. This is one of the reasons why RAID 5 is one of the most popular types of server storage topologies in use today.

In this instance the client’s NAS had suffered a power outage. After power to the client’s site had been restored, the NAS would not boot up correctly and it was not possible to access the data held on it. Once the NAS was delivered to the Data Clinic lab, diagnosis identified faults to the NAS casing and corruption to 2 of the hard drives inside the NAS. This had led to a general corruption in the RAID 5. To recover the data it was necessary to get 3 of the 4 drives back into a working state so they could read and the data on them pieced back together using Netgear NAS RAID 5 configuration.

We've used Data Clinic twice now - once for my son's laptop which held all his University work and suddenly seemed to just die, that was recovered with ease. And then secondly in connection with work when our office computer system backups were somehow corrupted. These people really know their stuff - they are very helpful and professional and quick! Thanks so much for everything.

My company provides IT support to approximately 60 Yorkshire based companies ranging from small 10-15 users up to Enterprise sized organizations. Due to disk failure a client recently lost their entire database. We contacted Data Clinic and within hours a representative was onsite, several hours later the drive was returned, again in person by Data Clinic Manchester. I would not hesitate contacting them again, outstanding service in a market that can mean life or death to a business. 10 stars if there was an option!

Fantastic. Could not fault them at all, Brilliant, 10 year old iMac full of data and they had the data back to me in 72 hours. Communication via e-mail was fast, clear and superb.

Sent them a 4tb WD Red hard drive to recover. They quoted me £588 incl VAT and recovery media. I was a bit sceptical so I asked for it to be returned. First they sent me the wrong hard drive (a 500GB WD Blue). Not too careful about data protection then. When I eventually got the drive back it had been totally stripped and outer casing binned (would have been nice to know about this beforehand). I decided to send it to Curry's PC World. They quoted £90 + recovery media. All data recovered and both hard drives returned within a week. What more is there to say.

Awful communication, I was constantly chasing them for updates on my device. My device was with them days before work was started on it. The data this company couldn’t retrieve was later retrieve by Apple. Waste of a £110.
