@ Manny: Actually, if I actually attempt to do this, it would make things simpler in a way. I like things clean, my desktop has zero icons and my taskbar auto hides. This would take un-needed drive references out of my Windows Explorer drive list.
@ Steve: See my above response to Manny for a reason plus there are a few others.
1) A while back I almost wiped my internal image drive when I meant to be formatting a flash drive. If my image drive is not listed I can't make such a mistake.
2) To me it is an interesting experiment. You know me... I like to experiment with code. This is the primary reason, I'd like to see if I can do it.
3) I DO like to isolate my drives, it has become habit if doing a dual boot ever since the days of Vista when Vista would kill XP restore points if the two were in a dual boot. If you remember the name Bert Kinney (if I spelled it right, several years ago he was considered the guru on System Restore) he asked my permission to post my solution to drive isolation on his site. I wish he were still around as my method of just removing the drive letter of the other OS is MUCH more 'eloquent'. While I do not do a dual boot on my desktop I still do on my laptop between 7 and 10. If I can make this deal work I can 'un-isolate' the other OS drive shortly before a scheduled image backup. Give enough time to do the complete drive image and 're-isolate' the other OS drive. It makes the entire process automated and, to me, automated is simple.
@ Pete: Mayhaps I should not have used the word 'security' as that is not the real issue. Safety would have been a better choice of wording. Also, as stated above neatness and most important, to see if I can do it.
BTW... Here is your rock throw!
