Reserved block count:     9157150
Block size:               4096

x * y = 37.508x10^9

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hdb1            721075720 694171948         0 100% /data2

1024 * (721,075,720 - 694,171,948) = 27.549x10^9

Looks to me as if there's something else going on as well as that then.
