Disk Failed, Contents Emulated, Parity OK?

[fnwc]

Question: I had a disk fail due to uncorrectable writes. The disk was then taken out of the array and the contents emulated.

 

I put in a new disk and started rebuilding the array, but I'm wondering if the file copy that caused the write error would be ok or not. In other words, can I trust the parity to be correct in being able to reconstruct the missing data correctly, or should I assume whatever file(s) failed to copy are corrupt?

It should be OK but the only way of knowing for sure would be if you have checksums (or are using btrfs).
