Hi

One of the problems using USB drives to store anything ,
Is the way Usb drive letters are allocated by windows your drive takes the next available drive letter when it is inserted.
So lets say you have a usb drive in your machine at start up depending what other drive letters have been used D for cd drive etc the first usb will be E.
You plug in your biab stick it gets the letter F
You do your installation and tell biab what drives to store what,.
Fine .
As long as tomorrow when you switch on conditions are the same and no drives have been moved, or added with the biab drive removed.

However if you have used the pc in between and removed usb drives and inserted others for say photos or docs etc, and left them in, your biab usb will get the drive letter available now if you had taken it out and reinsert it today
Which will not be the same. Thus confusing the biab paths set in instalalation

The answer in part is to choose a skt for your biab drive and leave it in.
This can be a problem if you are short of usb sks
Just my thoughts
