B Tree Problem

my mac has been playing while it’s 4 years old figured normal. crashed more , screen wouldn’t go on when booted. won’t go past gray apple screen, shuts down. won’t start in safe mode. fsck returning problem catalogue tree b , hasn’t fixed after more tries care remember. when fsck_hfs –r dev/disk says it’s rebuilding catalogue b tree says not repaired. fsck-hfs-d got bad super block problem. fsck –b32 goes b tree problem.

won’t load techtool off apple care disk. load hardware check off os disk , says fine won’t load os disk- sounds trying ejects disk , goes grey screen. when press option turn on doesn’t show disk. can’t afford disk warrior.

other options left with? can reformat without getting os disk work? i'm thinking may buy new harddrive once have installed see if can save off old one.

edit: ran hardware test again, time says hardrive has error
