How to Rebuild RAID 0 Without Losing Data

RAID 0 is a type of RAID array known as “Stripe” or “Stripping.” This is because it emphasizes data stripping. Disk striping means splitting data into multiple data blocks and spreading it across multiple storage devices connected in an ARRAY. SSDs or HDDs can be used for RAID 0 setup.

Apparently, RAID 0 comes in handy in applications where data needs to be accessed quickly. But before switching from a single-drive storage to a RAID setup, it is important to first backup your files on the drive using a reliable data backup software program.

Understanding RAID 0

Redundant Array of Independent Disks (RAID) is a modern disk storage approach adopted by companies and even individuals that have to deal with chunks of data. There are different types of RAID setups, which are commonly referred to as “ARRAYS.”

This storage technology is increasingly popular because it offers improved data access, higher performance, and data loss mitigation. When one of the RAID array disks fails, your files can still be accessed.

RAID 0 is the foremost RAID array setup and it is widely used by many top firms and individuals. It is a type of RAID array with data is split and saved across all drives in the setup. You need a minimum of two SSDs or HDDs to make a RAID 0 array and it offers better data protection compared to other RAID array types.


  • Supports disk striping, which means improved performance since the storage setup will deliver maximum bandwidth – combined from all connected drives.
  • Affordable to set up, easily compatible with all hardware controllers
  • All available storage space can be utilized and used to store data


  • The major, and maybe, the only disadvantage of setting RAID 0 is its lack of data redundancy. This means that if one of the RAID disks fails, the entire array has failed.

Common Reasons for RAID 0 Failures:

RAIDs don’t just fail on their own, there are quite pointable reasons why a RAID 0 array, or any RAID array at all, would fail.

1. Physical Damage to One or More Drives.

Apparently, physical damage sustained by one of the drives puts a threat to the entire data saved on the array. Just as you shouldn’t let your single-storage hard drive sustain physical damages, your RAID disks deserve such protection too.

2. Software or Driver Corruption.

If you’re running software RAID (although not always recommended), any issue with the controller will lead to a fatal RAID failure disaster. Also, if your disk drivers are outdated or corrupted, your RAID will fail.

3. Incorrect Configurations or Human Error

RAID arrays are distinguished by their configuration patterns the configuration of RAID 0 differs from that of RAID 1 and every other RAID array type. Incorrect configuration of the RAID array or human errors may lead to total failure and loss of files.

Preparation Before RAID Rebuild:

When your RAID 0 fails, you can rebuild it and continue to enjoy the benefits it has to offer. But before proceeding to rebuild your RAID 0, you should adhere to these important steps.

1. Ensure You Make a full Backup of Your Data

Honestly, it is worth overemphasizing the importance of making data backups, especially for your important files. While rebuilding your RAID 0 array is sure to go smoothly, as a precaution, you should back up the files in the other accessible HDD or SSD before proceeding with the process.

2. Get Your Stuff Ready

The next step after backing up your data is to get everything you need for the RAID 0 rebuild ready. Do you need a new drive? Controller? Or anything else as per your need? Get all these things ready before taking the first step to rebuild the array.

3. Keep Everywhere Tidy

This does not necessarily refer to your physical environment, keeping everywhere tidy is mainly to ensure that your drives are in good condition, physically, and all items you need for the RAID setup are well placed around your work desk.

Step-by-Step Guide to Rebuilding:

After you have carefully acknowledged the prerequisites explained above, you can head on to rebuild your failed RAID 0 by following the steps below:

1. Check the Health Status of Each Individual Drive in the Array

Firstly, run a S.M.A.R.T. on all the RAID drives, individually, to ascertain they are all in good condition. If there’s a faulty drive, replace it with a good one before you start the rebuilding. If you proceed to rebuild your RAID with a faulty drive included in the disk array, the process may stop halfway and never get completed.

2. Identify the Root Cause of the RAID Failure

This is very important, you need to know what made the initial RAID array fail. Only when you know the cause of the failure, will you be able to tackle it and get everything working back in order.

3. Use a RAID Management Tool or Third-Party Software for the Reconstruction

In most cases, it is best to use third-party software programs to rebuild your RAID array, since the developers of the programs could offer you professional assistance to ensure a smooth rebuilding process. But if you’ve got a proprietary RAID management tool, you could use it oo.

Useful Tips to Avoid Common Pitfalls During RAID Rebuild

  • Never run the CHKDSK command on the disks, it’ll cause more problems to whatever issue you’re facing already.
  • Never proceed to use a drive with bad sectors in the array, the rebuilding process won’t complete.
  • RAID rebuilding doesn’t always go smoothly, so make a backup prior.

Post-Rebuilding Steps:

After you have successfully rebuilt your RAID 0, here are some handy tips on what to do to ensure you don’t lose your important files and data.

1. Verify Data Integrity

Verify that all your files are data were copied back to the rebuilt array. If there are missing files, you should attempt to recover them using a data recovery solution.

2. Set Up Regular Backup Schedules

Everything may be looking fine at the moment, but you can’t predict what could happen in the next hour. So, you should set regular incremental or differential backup schedules for the tons of data being saved to your RAID array.

3. Regularly Monitor the RAID Array’s Health Status

Pay attention to the health status of your RAID array; you can monitor the health status through the controller. Depending on your RAID controller, how to keep an eye on your RAID array’s health status will differ.
