>From what I have been following on that I first got the impression that the new FUA command is about writing data to the medium with a higher priority than cached data which was written via normal write. Sounds dangerous, but disk write can always be dangerous. If the driver knows what it is doing (say, writes some area of the disk only via FUA and never uses FUA on other areas of the disk), I could think this can be useful under circumstances. And if the driver does not know what it is doing then it won't need the FUA to mess the disk up. Life is a risky busyness. Now I hear that FUA is only about making sure data have been written to the disk. Can this not be done by normal write and then issuing "flush cache"? I have not investigated the flush cache command, it has been introduced last 2-3 years or so (I asked why were there no such command about then, and some people did not want to hear about it...), but I would expect that this is what this command is all about.
