Replace the bad disk of your array and then allow it to rebuild. If after that your array is still raw, check if there is another disk that went bad, and replace that. If not, build a new array (I wouldn't recommend RAID 5. RAID 1, 6 are much more reliable), then just restore the data from your backups.

All three disks are in RAW format, two of them are online, the other one is on error.
I could't replace this one, because the remove disk option is not enable.

What kind of RAID controller is? Is this a hardware RAID or software one?

Means you are working with dynamic drives which you combined into RAID via Windows Disk Management, right?or is this an onboard RAID controller?

Can you list the brand and model of the hardware components in the server so we can help you better?

Looks like the old RAID-5 second disk failed problem.

RAID-5 can sustain failure of one drive, but if not replaced and rebuilt, a second drive failure means your data is lost.

Two points about RAID-5
1) Not recommended implemented via software due to the high CPU overhead involved.
2) Now not recommended at all with v large disks (>500GB) due to the risk of a second disk failing during the extended rebuild time of the first disk.

Consider RAID10 or maybe RAID-6
