E2fsck's "-c" Option
A more common use case is the invocation of badblocks as part of e2fsck when passing the option "-c" to scan for bad blocks and prevent data from being stored on these blocks. This is done by adding the list of found bad blocks to the bad block inode to prevent the affected sectors from being allocated to a file or directory. The test can be done using a read-only ("-c") or non-destructive read-write ("-cc") test method.

Famous quotes containing the word option:
“Our passional nature not only lawfully may, but must, decide an option between propositions, whenever it is a genuine option that cannot by its nature be decided on intellectual grounds; for to say, under such circumstances, “Do not decide, but leave the question open,” is itself a passional decision—just like deciding yes or no—and is attended with the same risk of losing the truth.”
—William James (1842–1910)
