Rescue Your Data With NAS RAID Recovery
HP RAID 5 DRIVE:
I have set up a number of hard drives in a RAID 5 configuration on a HP Proliant Raid Server. The array is built into a server which connects to my computer, and which keeps the data which is downloaded by my network. I am usually able to see this data when I open the server, but this morning I could not view the data drive. I was not even able to see the array when I searched for it through the server, and when I went into Windows’ Disk Management Utility, I saw it. The drive is now labelled unallocated. I have not seen it marked as this before, and so far I have not been able to view any of the files and folders which this drive should hold. I know that the server is working, and I can see all the lights on when the array is connected, but I can’t recover the data. I don’t want to do anything which could put this data at risk so hence contacting you guys to do the recovery for us as you come highly recommended.
I have been trying to replace an old 3-drive array with a much larger array. The new model that I want to use has 6 Seagate hard drives, each with 1TB of space. This array is already working in a RAID 5 configuration with some data on it, and I thought the computer would have no problem in switching from one to the other. However, when I tried to get the computer to set up the RAID, I was told that the controller could only handle a small amount of data. I want to be able to use the files which are on the 6-drive array in the computer, and I don’t want to have to start using the 3-drive array again. At the moment, I am unable to use the 6-drive array, and can’t replace it into the old system it was using, as that computer has failed and is no longer operational. It is so important for me to recover the original data.
Rescue Your Data With NAS RAID Recovery
Network-attached storage (NAS) can be as small as a single hard drive, but is more often a number of drives that comprise a central data store for a computer network. NAS is often put together in a format that provides basic file storage capacity, but it is also compatible with providing specialised software and hardware configurations. NAS provides a very convenient method of not only saving and storing files, but also sharing files across a number of computers via a local network. These types of systems allow fast data access and low administration burdens compared to file servers and so are a popular option for many people.
There are a number of different formats that NAS can take and so recovering data from a system can be a complex process. NAS usually takes the form of a number of hard drives that are often arranged into logical storage areas. It is common practice to utilise RAID architectures and configurations in NAS and therefore all of the complexities of RAID recovery will apply to many NAS systems. Common manufacturers of NAS systems include Lacie (Lacie Big Disk Systems), Data Robotics (Drobo Systems), Netgear (ReadyNas Systems) etc.
In order to recover data from NAS then a detailed knowledge of the storage raid system will be required in order to carry out the recovery successfully. The file-based protocols that have been used will need to be known as this will affect the file location and distribution. Also, NAS systems are rarely limited to using a single protocol and so a number of different protocols may have been used within a single system. These can include NFS, which is used on UNIX systems, SMB/CIFS, which is used by systems running Windows, AFP that is used by Apple Macs and NCP that is used by OES and Novell systems.
There are a number of different things that can cause data to become inaccessible to users on the network. There is always the possibility of user error causing the drives to be inaccessible if there is not robust system management in place, plus it is a possibility that data is accidentally deleted as well. In more serious situations the NAS will suffer physical damage that can be due to physical defects in a drive, or perhaps due to the effects of an electrical surge.
If a RAID system is being implemented within the NAS (more than likely) there will also be factors to be taken into account depending on the architecture and configuration that has been used. A RAID 0 system has different properties compared to RAID 1 or RAID 5 systems, which will dictate some of the complexities of the job.
So, if you are unlucky enough to find that your NAS System becomes inaccessible then your first step should be to give us a call and talk through the issues with a NAS recovery specialist. You will get the benefit of 14 years of company experience in recovering data in diagnosing the fault and also a quote for the cost and time it will take to recover the system based on its complexity and urgency.
