It seems to be an import pipeline bug.

Photos does a lot of extra work on import (merging RAW+JPEG pairs, generating previews, database indexing, optional deletion), so my guess is a concurrency bug where a buffer gets reused or a file handle is closed before the copy finishes.

Rare, nondeterministic corruption fits the profile.

Interesting that he went from 30% failure to it taking a while to find a single failure after replacing everything.

Random is random, and random is clumpy, so maybe swapping parts is irrelevant, but... I wanted more detail how often the corruption happened throughout his replacement journey.

edit: also wth i just realized I went to "tenderlovemaking.com" at work. gross. lol.

Since it looks like a concurrency issue, most likely the new laptop made the issue less frequent through the simple virtue of being faster.
