CREATE TABLE table_name_7 (hdd_capacity VARCHAR, _number_fdd VARCHAR, fdd_capacity__each_ VARCHAR)

Tell me the HDD capacity for # FDD larger than 0 when FDD capacity is 710kb
SELECT hdd_capacity FROM table_name_7 WHERE _number_fdd > 0 AND fdd_capacity__each_ = "710kb"
SELECT "hdd_capacity" FROM "table_name_7" WHERE "710kb" = "fdd_capacity__each_" AND "_number_fdd" > 0
