"Media wearout indicator" is a vendor-specific attribute. In fact, there are NO standard (or as the article coyly calls them "basic") SMART attributes at all.

"Media wearout indicator" is a vendor-specific attribute. In fact, there are NO standard (or as the article coyly calls them "basic") SMART attributes at all. A lot of vendors stick certain attributes into same slots, granted, but there's literally no industry-wide spec for any of the attributes. You have to go not by vendor, and not even by device, but by firmware revision to accurately interpret an attribute. The wearout indicator often sits at slot 233, but sometimes it will be in 230, sometimes - some other slot. Moreover, in some drives (e.g. OCZ or ADATA) 233 is undocumented at all and it will grow from 0 normalized. So this: > we implemented collection not of all the attributes, but only basic and not vendor-specific ones  is misleading and inaccurate.
