What is RAID 4?

RAID 4 array

To begin with, RAID is a disk bundle of several devices, such as hard disks, which is necessary to increase the reliability of data storage and to increase the speed of reading/writing information. RAID has several configurations: 1, 2, 3, 4, etc. and they all perform different functions.

This article will focus on a rather rare RAID-4 array - it is presented with block striping and parity on a dedicated drive. This array can be easily expanded in size by simply adding physical disks to the RAID, and there is no need to completely rebuild the entire RAID.

However, with all these advantages, there is one BUT: RAID 4 provides only reliability, while performance does not increase, and sometimes even worsens it.

RAID 4 failure reasons

RAID 4, with all its reliability, can fail and lose all accumulated data. As a RAID 4 includes multiple hard disks, then the probability of data corruption increases. If one hard drive is damaged, then the restoration of the entire array will be required. It is known that a hard drive is not eternal and, sooner or later, will require replacement due to physical wear and tear, system or hardware errors, etc. Therefore, the presence on the desktop of good software for data recovery from RAID 4 will be beneficial and timely.

It should also be noted that when creating or deleting a raid, all information from the disks will inevitably be deleted, so before creating a RAID, first save all the necessary information (if any), and then do the experiments.

RAID 4 data recovery with DiskInternals

DiskInternals RAID Recovery is the same software that is better and faster than other RAID 4 data recovery software. The application recovers files from a RAID connected to a dedicated RAID controller, such as HP, Adaptec, DDF-compatible devices, Silicon RAID controllers, etc. This is where file recovery from Microsoft RAID software takes place.

The application is equipped with a recovery wizard and a free preview. DiskInternals RAID Recovery has many unique and useful features, which include: it necessarily supports Unicode file names and multi-level folders, neglect of Windows restrictions, data export to local or remote locations, and much more.

Use the instructions for DiskInternals RAID Recovery:

Download and launch RAID Recovery™ on a PC.

After the application is open, select the desired array to search for data.

Then select a scanning method:

  • full search
  • fast search

RAID Recovery™ automatically checks the status and operation of the file system and disks, the array, and restores files where possible.

After scanning, you will get read access to the files. At this time, review all or select the recovered files and evaluate the quality of the application.

If everything suits you and you are satisfied with the work done, buy a license for RAID Recovery ™ on the site right now and you will get full access to your files. It will also be possible to export selected files to any suitable device for the accumulation of information.

How RAID 4 fail can be fixed

If RAID 4 is broken (one or more disks are unavailable), now is the time to bring it to life, especially if you used RAID Recovery™ in advance and returned the data.

So, there are several options:

  • Add another hard drive (it should be identical to other drives in the array).
  • Rebuild the array. This option can be considered with normally working disks, i.e., the cause of the damage to the array is unknown.
  • Format the disk when you see that the disk has become RAW.
  • Rebooting the OS will save you from a single system failure.

One of these options should work and make RAID 4 work. Good luck!
