Once you've tweaked the Columns, if you right click the Columns > Customize Columns… > Create a New Column Layout via the 'Plus' icon > Enter all your Drives into "Autoload on Path" /w "Valid For All Subpaths Under This Path" Checked & type out & click Add for each Drive (an Asterisk should appear in the Combo Box, then Save, when you open any New Tab or Folder, this Column Layout is enforced strictly, it's amazing, I had this same issue but it's fixed !
Add the New Drives like this:
C:\
D:\
F:\
G:\
H:\
(one by one, the C:\ & D:\ are my Hard Drives, & F:\ & G:\ & H:\ are my removable USB drives.) & voila, you'll never have to resize the Columns or worry about them again !! —Hope it helps !
