pal666 Well, both metadata and data are forms of data..., information is when it is new, as soon as it is known it is no longer information but data. Metadata describes relevant information about data, both are concepts, it's just a matter of semantics. From my understanding, modern file systems are smart enough that in case if data gets corrupted, metadata is updated about corruption after file system access/checks. So by checking metadata, fsck "checks" data too (sort off). In some (again very unlikely) scenarios corrption might happen in the way that metadata does not get refreshed, but my point was that improbable possibility those scenarios simply do not have benefit for desktop users to drag around more unnecessary complex file systems that in their nature should be as basic as possible to avoid security and other risks (to add, in other words, those "features" introduce complexity that rise a chance of data corruption at the end).
Just my non-informed logical view.Last edited by leipero; 19 November 2017, 06:32 PM.
