hi,
from what i can tell, the "super on" command has been the same probably since at least 2008. i want to say i found a much earlier reference to it but i can't find it in my history
from the victoria changelog from 2008-08-13 4.46b: "Added support for super-SMART for IBM / HITACHI ("factory" attributes)"
from
http://forum.ixbt.com/topic.cgi?id=11:42461-72, there is a link to a tool which sends the command, ibm_ss.exe:
http://vlo.name:3000/tmph/ibm_ss.rari attached an image showing the disassembly of ibm_ss where it sends the super on/super off - the command is clearly visible and the same.
i can't find any references to the clear smart vsc, however. just the super on/super off that *seems* to go back to ibm drive days.
the mhdd script i obtained did clear many smart attributes from the WD80EFAX drive, but it unfortunately did not clear the actual error log. UDMA_CRC_Error_Count did go to 0. my main goal was to clear the *log* though
Power_On_Hours and other wear-related attributes were not changed. i attached a before & after of the attributes cleared if anyone is interested.
if anyone knows the vsc or otherwise to clear the actual log, i'd be very much appreciative
and, as far as the logic of selling the same drive for $100 less as an external vs. internal, well. i guess western digital doesn't have any other (cheaper) 8tb skus. they have the purple but maybe it's not suitable for desktop/external use?
i did make a quick collage of an earlier gen wd red drive (WD20EFRX), my drive (WD80EFAX), and a hitachi helioseal 8tb (not sure of model). the WD80EFAX and Helioseal look identical, so that for me at least answered the question of it's a rebranded hitachi. this might be a "well duh" for the rest you
although this is supposedly 5400 rpm while i only see 7200 rpm skus on the hitachi website...
thanks,
-matt
