, you too can be a Nerd.
Either open a text document; or get an excercise book, like we used at school, as kids.
Write 1.) ... I suggest using an excercise book cos there may be some scribbling and page ripping, however; meditate on that 1.)
Now, just by being around I note you have another couple of threads running, so turn the page, and write, 1.) again on another page.
And another till you have a bunch of pages with 1.) on the Top of them.
Give the 1.)'s a Title, like; "is there a way to empty the hd completely," ? will do for starters, and write the most important factors about this Thread, and the problems you have, in 'point form'.
After time, some semblance of the key factors will appear, plus relevant info will gather.
You can then refer to each individual factor, + project, and have no confusion, adding the points posted in each thread that you find important, helpful, and so on. Sounds like a lot of work but hopefully you'll find you're aware what's going on, you just had to clear away some debris to see a clear path.

After awhile things will fall into place, no worries.
I'm not saying this is a quicker way to do what your doing, but it will be clearer.
That's the way I have to go about things anyway. ( I may have incurred some 'Brain Damage' in the latter part of the 1960's, ... dunno
