This option is normally used when the primary superblock has been
-corrupted; most filesystems have primary superblocks located at
-blocks 8193, 16385, etc. If an alternative superblock is specified and
+corrupted. The location of the backup superblock is dependent on the
+filesystem's blocksize. For filesystems with 1k blocksizes, a backup
+superblock can be found at block 8193; for filesystems with 2k
+blocksizes, at block 16384; and for 4k blocksizes, at block 32768. If
+an alternative superblock is specified and
the filesystem is not opened read-only, e2fsck will make sure that the
primary superblock is updated appropriately upon completion of the
filesystem check.
