This. I want this! Hard disks are the only part of a computer that is not replaceable. Everything that improves data integrity is improving computer usage as a whole. Improving data integrity is improving user confidence in the machine. This is something that OSes should have done years ago. All any user ever does on a machine is manipulate and work with his personal data. Absolute data integrity should be paramount to any computing technology. Alas, it is not, and we all have (hopefully) several backups. Again: Anything that improves data integrity is improving computing as a whole. I want this.
