[Ghorai] I think Russell also mentioned his opinion. Would you please add your idea too? 1. I would prefer Adrian to explain again what this statement means, in the context - data read fail and how we make it success? 2. if data read fail for sector(x) why we have to try for sector(x+1, ..x+n)? 3. how to inform reader function which sector having the valid data out of (1...n) sectors. 4. do we have any driver/code in Linux or any other os, which give inter-leave data and return as success? > > I think it's possible to merge patches to improve the situation (such > as the idea of noticing a card disappearing earlier), but your initial > patch is not the patch to do that.
