[SOLVED] RAID 1 not working after BIOS update ?

[martipe1]

My system has 2 RAID 1 disks (4 disks total) created with Intel Rapid Storage Technology, one for OS and the other for data, my motherboard is PRIME H270M PLUS, and running Windows 10.

I updated my BIOS and somehow it damage my RAID array, If I try to start my PC it enters directly into the BIOS, it shows not bootable devices, but the disks are shown in Intel RST. The RAID for OS is showing verify. I managed to boot my PC changing from RAID to ACHI, I can read the 4disks with no problem, I would like to create again my RAID 1 arrays, but every time I change ACHI to RAID can't boot and enters directly into the BIOS.

Any suggestion on what to do?

Thanks

I've learned to never use a RAID array for the OS since the tribulations of having to reinstall the OS and the amount of down time associated with dealing with a RAID array for said OS is too long when compared to having a RAID array for data alone. I'd advise on keeping the OS on it's own drive, preferably an SSD and have your RAID array for data.

Re-enable raid in the bios then save and reboot.
If you used the bios to create the array, the raid info is written to the drives and it should work fine afterwards.

Also please realize that raid 1 isn’t a back up. It should never be treated as one or you are going to lose all of your data one day

Raid Is for maximum system up time. It is not a back up for your data or your operating system and it’s a huge pain in the ass so I refuse to deal with it on any level. It is also useless with SSDs as far as performance goes

My recommendation is to have only one drive connected, install windows clean, and then put your other drives back in and do normal back ups

Thank you very much for your answer, but that solution didn't work for me . In the end I had to reinstall windows .

Thanks!!
