- If you do a factory format of all tracks for example with SeDiv "S" will be cleared like G-List, S.M.A.R.T., etc as all tracks will be gone (on platter). Now if you power off/on drive will be ATA locked. You have to re-create "S" using for example same VSC to clear password as that will make the drive produce the initial "S" and write it on track.
Toshiba drives don't clear "S" module , SMART module, etc.....They replace them with template modules that are stored on the same tracks....Format tracks will erase the template modules as well...
WRONG ....
Try this :
1 - Use SeDiv or whatever tool and do a full format of the track.
2 - Check drive. It will be locked, slow, etc ....
3 - Use SeDiv or even directly issue the command to regen "S" module. Drive will be unlocked but still slow to detect as you don't have G-List, S.M.A.R.T., etc ...
4 - Use the command to regen G-List (clear), re-gen s.m.a.r.t. ,etc ....
5 - Drive will go full speed and will be ok.
6 - Now use your head and think ... IF Format tracks were to erase the template modules as well how would the command to regen the security work ? Just test it out and you will see ! Truth is when you do format tracks you can regen stuff and drive will be back to normal so regening with VSC doesn't require data on tracks (templates) to be there as you did already erase them with format tracks and you are still able to regen track modules by VSC !!!
