Is there any kind of error statistics for hard drives? Geometry is known. I suspect that structure of damages, caused by contact of plates surface with head, can be classified. It may be possible to classify manufacturing glitches. I think HD producers have this kind of classification/statistics - to improve quality, keeping price low. Actually what I'm thinking of: some kind of design rules for file systems, how to minimize crashing due to hdd glitches. Let's say, if some of hdd regions are know to be more error prone - desing fs to use those regions less. If hdd damages used to have some specific structure - design file system to keep renundant data in regions which are less likely to be lost both at the same time. So renundancy would make sense. Is there any thing like this? Or file systems now do outlive hard drives?-) -- Ihar 'Philips' Filipau / with best regards from Saarbruecken. -- "... and for $64000 question, could you get yourself vaguely familiar with the notion of on-topic posting?" -- Al Viro @ LKML
