Restoring a Normal RAID-0 State

Good afternoon!

There is a stripe raid for two screws on a working computer. Once he left the normal state due to either a power failure or a loose cable.

Is it possible to somehow return it back without a complete interruption (the safety of sectors with errors that arose as a result of the mentioned failure does not bother)?

When installing the driver from Intel ("Intel® Rapid Storage Technology"), it is possible to mark the raid as "normal" using the program that comes with the kit, but this does not last long.

The reason why you want a “normal” state is wild brakes due to data verification (this happens at the raid controller level and takes almost all disk time)

UPD.
I perfectly understand what a stripe is. I am well aware that he is unreliable. I don't need reliability, I need speed. I will formulate the question again: everything works for me in terms of data availability, but one of the disks is constantly reset to FAIL, which leads to brakes. So, the question is: why is this happening and how to fix it? Please do not offer to recreate the array, I myself understand that this can be done, only it takes a lot of time to kill.

add. info.
looked at the SMART status - everything looks fine.

UPD2.
I checked it a couple of times with a checkdisk, there was an enchanting number of errors. I tried to disable the writeback cache - maybe it's buggy on the Intel controller? If anyone has experienced this, please provide more information.

The brakes will go away after a full verification of the data occurs.
But it's better to merge all the data from the raid and either use 2 separate hard drives, or make RAID1-RAID5. For as stated in one FAQ:
Q: What is RAID0
A: This is how much data will be left after any problem with the RAID.

RAID0 is a stripe. If it falls, then it falls forever.

you don't have a raid controller. What you have is called a fake raid.
