Distinguish fixed hard drives from ext. removable HDs

[klownboy]

There's been some past history on this topic, but....I've noticed that using SC get("drives", 2, "|")) will feedback the removable flash drives but not the "removable external" disk (hard) drives, at least not for me. Using get("drives", 3, "|") results in all the fixed "internal" hard drives (in my case example C:\ and D:\), but will also give the external removable USB hard drives like a WD 640 Western Digital external removable USB interface hard drive so the result is C:\|D:\|F:\. Is there any known or established SC way to separate or distinguish the known physical fixed (i.e., in the laptop or desktop (C:\ and D:\) from the "removable external" drives, but not detected as "removal" using get("drives", 2, "|"). Would I have to eliminate the 2 known "physically installed" drives C:\ and D:\, which unfortunately will be different for each computer (so a modified script), from the full list provided using get("drives", 3, "|")? I've been looking, but I don't know of any XY or system variable which give me just the installed fixed hard drives.
Thanks,
Ken

Not possible ATM. The standard Windows function for this is lying, and it is quite complex to get the truth here out of Windows. One day...
