Hard drive failure?

[XnavxeMiyyep]

When I try to boot OS X normally (or in Safe mode), I get the usual Apple logo plus the spinning gray circle of lines, but also a progress bar that never progresses. It either stays at that point or shuts down.

When I boot in Verbose Mode, or run /sbin/fsck -fy in Single User Mode, I get output that looks like the following:

** /dev/rdisk0s2
** Root file system
     Executing fsck_hfs (version diskdev_cmds-491~1).
** Checking Journaled HFS Plus volume.
** Cheching extents overflow file.
** Checking catalog file.
disk0s2: I/O error.
    Invalid node structure
(4, 28704)
** Rebuilding catalog B-tree.
** The volume Macintosh HD could not be repared.
/dev/rdisk0s2 (hfs) EXITED WITH SIGNAL 8

I've tried zapping PRAM and swapping out RAM, so I'm gueessing that means the hard drive is messed up. (Although I can still browse through and write to files in Single User Mode).

Any feedback on whether my conclusion is reasonable?

Have you checked the drive's SMART status?

Have you checked the drive's SMART status?

Nope. How do I do that?

EDIT:
It seems diskutil cannot be run in Single User Mode.

EDIT 2:
After running fsck_hfs on my drive, I got:

** The volume Macintosh HD was found corrupt and needs to be repaired

Apparently, this is a known issue with my Macbook model, so I guess Apple should replace it for free.

My hard drive failed just after 3 months of me buying it. They repaired it for free but since my protection plan is now expired, I'm not sure of they would do it again. At any rate, I'm convinced the reason the HD failed was because of all the stuff I was downloading from limewire. Since that day I haven't installed any kind of shareware software or bit torrents and she hums along just fine. make sure you leave 3 or 4 gigs of free space so it can operate smoothly, doing this has ensured me minimal hiccups.
