we are in disagreement on this. If partition table entry corrupted, you can't mount without some low level surgery.

depending on raid, your data will be duplicated on another disk, and will survive in case of one/few disks corruption.

The partition table gets mostly written only once in the lifetime of a filesystem/disk. So it almost never corrupts during an os crash.

There are a lot of RAIDs and configurations. Some of them may do what you describe, but most don't.

Ok, I know this, not sure what is your point.
