Music Creator 6 scans

Have you checked the Plugin Managers settings? AFAIK also in MC its possible to define what is scanned at launch (I don't have MC, though).

well, it doesn't scan your entire hard drive, it scans the folders you have set it to scan in the PREFERENCES for VST folders.  if you've not added anything then it only scans one folder (and subfolders) which is the default location.

if it's "hanging" on something it's not because it can't find it, it's because you've got a bad plugin that's causing problems.  I would advise deleting that plugin that is causing it if it's a freebie (likely), or if it's a cakewalk plugin then there's a problem and reinstalling that plugin might help.

disabling scan at startup as herb is saying is an option, but it's not necessary, really with MC6 (and the X1 versions) because while it does scan at startup, it doesn't rescan everything that's already been scanned in the past, it just "looks" at them and scans for new ones in those folders.  scanning at startup used to rescan everything every time, now it only verifies they're still there and scans new ones which weren't there last time it scanned - which is very fast.

yes, with MC4 and MC5 that was the case, but not with MC6 (and X1).  Noel told us that in a thread in the X1 forum.  that's why I just leave it on now.  I had mine turned off at startup as well for 8.5 and below.
