Looks like disk1 is shot
197 Current_Pending_Sector -O--CK 200 200 000 - 214
Problem is that I'm not 100% sure what actually happens when parity is invalid (as it's building) when a read error happens on another drive.
If Parity is valid, then the system recalculates what's supposed to be on disk1 via Parity and rewrites the appropriate data. If the write fails, then the disk gets disabled.
But, since in your case if Parity isn't valid the above would result in corruption on disk 1. I *think* that the system wouldn't attempt to rewrite, but I'm not 100% sure.
Either way, your best course of action would be to replace disk 1 and re-copy the data.
@JorgeB Do you know what the OS does in this situation?
