Best Practices for Data Recovery from Netgear ReadyNAS

Businesses usually store their data in RAID systems. Similar to computer hard drives, they can break down and stop working for both physical and mental reasons.

Professionals with cutting-edge infrastructure, unique data recovery tools, and experience working with NAS equipment are needed to get back data from a Netgear ReadyNAS or a similar NAS.

  • Reasons NAS Data Loss
  • Insufficient cooling of the RAID hard drive
  • Unintentional loss
  • Multiple instances of improper shutdown
  • Changing or overwriting RAID setup files
  • Failure of hard drive head
  • Partition was written wrong
  • Changing voltage
  • RAID setup mistakes
  • Software problems cause database files to be replaced.
  • Configuration error in the server registry
  • Problems with the hard drive platter
  • Problematic driver

NAS usually shows a warning message when it crashes. This error message could be about problems starting up, file system issues, corrupted configurations, or something else.

You may realize you’ve lost your data even if there isn’t an error message because you can’t find or view it.

Can losing NAS data hurt my business?

Such as the Netgear ReadyNAS 12B, the NAS usually has 12 hard drives, each with 1 TB of space, set up in an 11+1 (hot spare) arrangement. This means the NAS holds a lot of your info. Virtually every process that needs this huge amount of data will stop working if you lose access to it.

We can help if your NAS was damaged or you think you lost your files. This is India’s most reliable and well-known NAS data recovery service, provided by BLR Tools. Request a free assessment call, and we’ll talk about what the best next step is. It’s sometimes possible to get your info back without sending the whole NAS to our labs.

File Index Loss Causes NAS Data Loss — Methods to Get Back NAS Data?

Still using a Netgear ReadyNAS 12B as an example? To show how ordinary NAS data recovery works, we looked at one of the most usual error situations. That is, the place where the RAID array’s file index is still missing.

A network attached storage (NAS) uses several hard drives to function as a single disk. These hard drives are usually set up in a RAID configuration, which maximizes NAS speed by using data striping and parity.

In the future, the volume will change to RAW format if the file reference is lost.

The cause can’t be found with any accuracy once the file table is damaged or lost. Unfortunately, this problem is usually caused by malware or bad sections.

How does the Normal NAS Data Recovery Process Work?

Each data recovery problem is different.

A full exam is necessary to get the right diagnosis and treatment, though, for all diagnoses.

Step-by-step instructions on how to recover:

1. A physical exam

It is checked to see if any of the NAS drives are physically damaged. Sensors, motors, and controller circuits are all carefully checked for damage.

While looking for broken parts, we check to see if that damage is what caused the data loss. In order to reach our goal of recovering the lost data, we don’t want to change any parts that aren’t needed.

2. Examining Logic

The team will now look at the device on a logical level after ruling out the chance that one or more hard drives are broken.

As a result, the hard drive is analyzed sector by sector.

If we look closely at our case, we can see that the file system information is missing from the RAID array, for instance.

3. Creating copies

The entire set of drives is copied onto a larger BLR inventory hard drive.

4. Reconstructing RAID

After checking the data on the original disk, our data recovery experts make copies of the disks. At this point, absolutely every single byte is accounted for. Zero errors are allowed while rebuilding. It is confirmed that the cloning is correct.

Each copied hard drive is coupled to the others. Multiple RAID parameters, including stripe size, parity flow, and data flow, have now been set using an array setup utility.

This creates a RAID copy. For reference, RAID is made up of several files that work together as one.

There is analysis of the finished image.

Here, we can find the RAID array’s files. When looking at a Netgear ReadyNAS, for instance, the team might find that the RAID array had two Windows files that were formatted with NTFS.

The situation can get more complicated here. Information in the file system could be broken. Not only does the data exist, but the volume, section, and file names that lead to it are lost. Our team can complete such a task.

5. Scanning closely

Logical scanning might not make the file index again.

This is followed by experts rewriting the file index script and rebuilding the file structure by hand.

Additional mistakes are checked by hand in the file index.

Using Disk Editor, you can fix the file system’s metadata so that it matches the saved data perfectly.

The image now gives us access to the info.

Successfully sending the info to a safe server.

Dealing with NAS is hard, but this data recovery project shows you what you need to do to be successful. The following are:

The ability to carefully check the gear physically to make sure there is no damage.

The specialized knowledge needed to carefully copy hard drives.

The NAS RAID needs to be rebuilt using a software tool to find out what configuration information is missing.
