+The @samp{xdisk_} are values from arrays of @code{GLIBTOP_NDISK} (defined in

+in the system.
+
+Please note that all of the disk values are absolute values measured in
+certain units since system boot. To get bandwidth values (bytes/s), you need to call @code{glibtop_disk}, save the
+result, wait some time and then call it again and divide the differences of
+the two values by the time spent reading or writing.
