I don't think that's possible anymore. Sharing all drives was really a "bug", it will make UMS scan a lot of files that aren't media files and this will make UMS very slow and also have the potential to cause random crashes and other issues. On top of that, some users consider it a "security issue" that files in folders they haven't explicitly chosen are shared.

What you can do, is assign drive letters to your removable drives in Windows. When you haven't assigned any letter, the drives will just "fill up from the bottom" using the alphabet and won't always get the same letter. If you instead assign it manually, the letters should be remembered on a per-drive basis and you should be able to configure UMS to use those specific drives.

It's impossible to please everyone. Others have made a lot of noise about this behavior, both because it makes UMS extremely slow (depending on how many files there are on the system) and because some claim that it's a "privacy issue".

In the meanwhile, UMS has changed so that it (since UMS 7.0) scans all shared folder during startup. This is necessary to make UMS aware of the available media to present it in the "media library", if you prefer to browse by category instead of by folder structure. Startup scanning and sharing "all drives" obviously don't go hand-in-hand. I can't quite see the difficulty in adding 6 shared folders though, I have many more defined.
