Prevent disk access/wake up

[Dreamer]

I'm not using the second disk all the time, so it's "sleeping" most of the time, but when I activate MP, it cause that MP wake up the second disk. Possible reason is the folder tree, even if the second disk is not selected.

Possible solutions:

- don't access/wake up any disk until it's activated, in the tree or file list
- in the folder tree show only the current disk/drive, C: for example (+ add the drive bar selection, as option)
- option (or ini option only) to hide custom drive letters, e.g. D:

Thanks.
