NAS / SAN / DAS & Network Storage Data Recovery

NAS and SAN are now widely used to store large amount of data in big businesses. These devices are generally accessed thorough network connection and have taken over the traditional file serving method and Direct Attached Storage (DAS), where server was responsible for serving/storing and managing the data.

Generally SAN is referred as “Block level storage and NAS as “File level storage”.

The SAN is known as Enterprise storage, it allows remote connection over a network with disk drives, tape drives for block level I/O, and it also uses Fibre and iSCSI protocols for the transfer of data over network at faster rates.

The NAS is mostly used as general centralized data storage for users with large amounts of data. NAS is widely used due to being simpler and low cost for load-balancing and fault-tolerance of corporate data, email and web server systems. NAS comes in various options differing in interface and type of drives, it has either SATA, IDE or SCSI interface which mostly works on “NFS, SMB or CIFS”.

Expert tips!!!

  • Never reinitialize drives
  • Do not force the drives online
  • Never change the sequence of the Raid Drives
  • Do not reinstall Operating system
  • Do not create new partitions
  • Immediately switch off Raid drives upon hearing unusual sound from the Raid drive
  • Label all drives according to their position in Raid Array
  • Always seek professional help, Call Disk Doctors at 0800 043 6611

NAS/SAN/DAS Data Recovery Process:

At Free Evaluation stage, we gather valuable information about the NAS or SAN boxes, such as:

  • Level of RAID if any i.e. JBOD, RAID 0, RAID 1, RAID 5
  • Exact issue with the media
  • Details of any hit and trial method carried out on the media by the client.

Once we gather complete information as mentioned above, we send an evaluation report with a fixed quotation for approval. Recovery starts upon approval; there are various specialized methods of recovery which may include.

  • Using a clean room facility to fix the physically failed drives and getting them to work.
  • Creating bit by bit secure replica of the media
  • Identifying parity technique, using in-house developed applications.
  • Rebuilding the data from fragmented stripes together (applicable to RAID 5 arrays)

Most of issues are very complex besides the points mentioned below, which is tackled with other in-house developed techniques. We guarantee to recover your data or you don’t pay us anything.

Data Protection & Confidentiality

Disk Doctors guarantees protection of your data throughout the data recovery process, from evaluation to handing data back to the client.

  1. Disk Doctor Employees are selected through a rigorous process of selection and follow our strict rules and procedures for handling the client data.
  2. Client media is cloned sector by sector onto our own lab media and all the data recovery work is carried out on the cloned media not the original media; this ensures that client’s storage media is always intact.
  3. Upon successful recovery Disk Doctors by default keeps a copy of the data for 7days before it gets deleted automatically from our Lab Server. This helps in providing the copy of data again if some thing goes wrong during the transfer of data to client e.g. the data media gets damage or goes missing during the postal process.
  4. Our agreement to recover the data includes the clause for protection and non disclosure of data as per legal rules and regulations. If you require separate agreement for data protection and non disclosure, we are happy to sign the agreement.

To recover your loss data we follow a standardized data recovery process in all our data recovery labs across the globe. Call us at 0800 043 6611 to consult your case or submit your case for free evaluation with No Recovery, No Charge guarantee.

I was very happy with the service and professionalism I encountered when dealing with your company. The options available, the quick turnaround & correspondence updating me with the progress of my call were all above my expectations and I have already recommended your service to colleagues.

While I hope I dont need such help in the future any HDD issues I cant fix will be coming your way.
Many thanks,

You service was good obviously an efficient e-mail run system is in place. One criticism though I took the trouble to point out the specific area where the PST files needing recovery were to be found but this was ignored and the wrong files recovered. it was only when I insisted that they were where I said they were that you did indeed find and recover them. As you pointed out at the start we had used another recovery company first who had failed to restore the files we wanted and on further inquiry insisted it was not possible to do so so hats of to Disk Doctor. We will use you again if we need to.
I was hugely happy with the work you managed to save from my hard drive. I have lost quite a few photos but that is NOTHING when I consider you got all of my work files back to me safely - that is truely the MOST important thing.
I found Shakeel very helpful and lovely And I was so pleased you adjusted the price. I was desperate from my information to be found but I had little chance of paying the first quoted fee.
I thank you and would highlyu recommend your service to anyone else.
All the best
