I'm not sure QueryDosDevice is more efficient :

what we want
+ if we call it with A: B: C: and so on, we still need a loop
+ plus, we have to dynamically increase the buffer size while 
GetLastError is ERROR_INSUFFICIENT_BUFFER

Would creating a new IOCTL_MOUNTMGR_QUERY_ALL_UNIX_DRIVES be (more) 
acceptable ?
