Updating BIOS might put your RAID in problems. For example, after updating your BIOS, any one of the drives in the RAID array might not be recognized as a member. This is because BIOS has complete information about RAID arrangement. Updating or resetting the BIOS might change the BIOS settings to default resulting in failed RAID. Here in this article, you can learn about the various manual methods to fix RAID after the BIOS update.
It would be unwise to assume BIOS update as the only reason for RAID failure. Some problems pertaining to hardware can also result in RAID failure like; damaged SATA cable or drained CMOS battery. So, before moving forward double check with the hardware and replace the CMOS battery if it’s not working.
Apart from reset or updated BIOS, the RAID configuration can stop working if the settings have been altered. If you can re-enable the RAID through the BIOS might actually make the RAID work as usual. The instructions on how to re-enable RAID through BIOS are stated below:
Re-enabling RAID should repair the BIOS settings. Unfortunately, if this didn’t work, you need to recover and recreate the RAID. In order to recover a RAID, you will need trusted data recovery software such as Yodot Hard Drive Recovery software.
For recovering RAID drive, disconnect the unrecognized or affected drive and connect it to your computer. Now download and install Yodot Hard Drive Recovery software:
This ends the recovering RAID drive. After completing the raid drive data recovery, you need to recreate the RAID drive. You can find the instructions for that in the next section of the article.
Note: While recreating RAID, the drive will be formatted, hence use the other storage device where you saved the recovered data as a back up after recreation of RAID.
If the re-enabling the RAID is not enough to fix the RAID after the BIOS error, recreating RAID array will solve fix the issue. For that after enabling the RAID in BIOS restart the computer and tap on Ctrl+I to create a RAID volume.
However, the setup will ask you to format the RAID array drives. Since you have already recovered RAID drives using Yodot Hard Drive Recovery software, you can proceed to format and recreate RAID array after BIOS update error.
Apart from RAID failure, BIOS update error is also a reason for other problems .such as interrupting BIOS update will result in corrupting or damaging the whole motherboard. Hence, it is strongly suggested to take a backup of important data before updating BIOS. Create an interruption-free environment, like have a UPS or keep your laptop charged.
Not all the BIOS updates will improve the system performance. So, once cross-check the performance advantages you get with the update. If there are no performance improvements better you skip the update.
CMOS battery will take care of BIOS settings while your computer is switched off. Most of the users are not aware of it so if the CMOS battery is interrupted or drained BIOS settings will reset and result in failing RAID array.
Conclusion
RAID arrays are best suited for storing large files. However, RAID arrays are unstable while BIOS is updating or reset. Fortunately, you can easily fix the RAID but the process also involves in formatting the RAID array. In such situations, you can recover the data from RAID array with help of professional data recovery software such as Yodot Hard Drive Recovery Software. After taking a backup of the data you can format and repair RAID after BIOS update error.
