I have a confusion regarding the fsck correction. I have corrupted an ACL block of an inode. Trying to understand how fsck corrects. What value does it compares and performs the correction.
Does fsck corrects the inconsistency of the file system by comparing the on-disk structures with the Journal or with the buffer. Or does it checks the superblocks with the other structures.

"Correction" does not necessarily mean what you think it means.
Typically, there are not multiple copies of data or metadata on the disk, and even if there were, it might not be possible to determine which one is the correct one.
fsckmerely changes the metadata so that the file system is consistent again. But the result might be an outdated copy, or some garbage that looked like correct data; in extreme cases, the only way to make the corrupted data consistent might be to delete it altogether.
