Simply having ECC enabled doesn’t mean that damaged files can be recovered. It appears promising, but needs careful real-world evaluation.
APFS
We assume what we know to be impossible, and pretend that just making ‘safe’ copies of important documents will preserve them for the future.
Apps don’t work like the Finder. Most use ‘safe saves’ designed to prevent a failed save losing the original document. Here’s how they work.
Do you want ECC for your important documents? It’s available now, free, without the complications of ZFS or cost of RAID 6.
A nimbler version of Dintch is designed to drag and drop files and smaller folders to tag then and check their integrity.
What happens when you copy a large file to the same volume, or duplicate it, on the same APFS volume? Here are the answers.
More about checking the integrity of files on macOS, with a new version of a free utility, news of the next apps, and error-correcting code perhaps?
The volume should only be half full, but installers and other software complains there’s insufficient free space. What to do.
To check the integrity of important documents, we’re going to calculate their SHA256 digests. But where should those be stored if HFS+ and APFS don’t have a suitable attribute?
If macOS can’t do it, how should we check the integrity of important files? Use a checksum, or a hash function? And which?
