I am curious as to what will happen if, for example, I only have 5 available drive letters in windows and I plugin in a USB HDD with 6 partitions. The 6th partition will not be mounted/receive letter, correct?

 

According to this http://superuser.com...tter-in-windows, the drive can be accessed via a shortcut using start \\?\Volume{ID}\

 

Is there a way to tell windows to NOT mount a specified volume/partition?

 

Thank you

Do the following experiment.

1) dump HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

2) add a disk like device with at least one volume on it

3) check using mountvol that the volume has been mounted

4) dump again HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

5) use mountvol to remove the drive letter from that volume

6) dump again HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

7) use mountvol to re-assign another drive letter to the same volume

8) dump again HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

9) open disk manager, right click on the volume and "change drive letter" and Remove the drive letter

10) dump again HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

 

 

Compare the various dumps, you should be able to see a pattern.

 

Then, looky here:

You can always use NTFS mountpoints for any remaining volumes that can't have drive letters. I do wish Microsoft would allow the use of drive numbers in addition to letters, since the English alphabet is limited to 26 letters, whereas numbers are infinite. Or better yet, adopt the Linux philosophy of "everything is a file", and stick to mounting drives etc as a directory/folder.
