Hint: In an OS using a page cache (=every OS) I/O errors are not reliably propagated to applications unless they explicitly sync their dirty pages.
- __jal 10y agoI'm aware of that, but I'm not sure what I'm supposed to take away from it in this context.
- dom0 10y agoThat it's difficult to accurately define "what the application thought it wrote" when considering corruption at various abstraction layers; somewhat similar to calculating checksums over already corrupted data.
