Why does a resumed download say some pieces “didn't survive the interruption”?

\n

Short answer: On resume, pieces that were mid-write when the interruption hit are re-checked and fetched again. It's normal: only those few pieces are re-downloaded, and the log shows how many were already kept.

\n

When a large download resumes, Storage Studio first checks the pieces it already has. Any piece that was being written when the interruption happened — a crash, a power cut, the lid closing — may be incomplete, so it's set aside and fetched again. The log tells you how many.

\n

That's normal and safe: only those few pieces are downloaded again, and everything else is kept. The log also shows a line like "Resuming — N of M pieces already here" so you can see how much was saved.
