+set. On Windows, disk devices are accessed as \\.\PhysicalDrive0 for the first
+device, \\.\PhysicalDrive1 for the second etc. Note: Windows and FreeBSD
+prevent write access to areas of the disk containing in-use data
+(e.g. filesystems). If the wanted filename does need to include a colon, then
+escape that with a '\' character. For instance, if the filename is
+"/dev/dsk/foo@3,0:c", then you would use filename="/dev/dsk/foo@3,0\:c".
