One of the things I really love about how the Quantel DPB-7001 "Paintbox" treats disks is how it could be a case study in how to responsibly not care about data integrity.

In fact, other than the directory listing on the first cylinder, the whole concept of a disk in general is illusory. It's treated more like linear video tape. And does linear video tape have integrity checking? Of course not.

Will bad data cause a crash? No, because the CPU doesn't even involve itself in the loading of images or brushes. The disk controller just hoovers up bytes and deposits them linearly in the frame stores or brush store.

As long as the PLL can maintain sync with the MFM stream, you're hot to trot. Any bad bytes will simply cause small speckles or spans of missing pixels, and the end result will still end up looking better than a still frame off a VTR.
