Really slow start up. What can I do?

In January I bought a 13 inch MacBook and it's been working great, I'm very happy with it.

But a few days ago, when I turned it on it took about 5 minutes to boot. I already did a disk repair (it found no errors), repaired the disk permissions and used OnyX to see if there's anything wrong. It still has this problem and I don't know what else to do. Sometimes it also freezes for no reason.

What can I do?
 
System Preferences / Startup Disk <-- reselect it

---

If that does not work download a SMART Utility.app and check to see if the drive has bad sectors and/or errors.

If it is freezing for no reason, back that puppy up, since it may be experiencing DMA errors and increasing bad sectors. You'll likely start seeing the drive degrade with increasing errors before it starts creating actual file system structure problems.
 
I just ran a SMART utility and this is what I got:



Do I need to reinstall OS X? Will this cause permanent damage to my HD?
 
SAVE THE DATA ON DRIVE ... Backup NOW

If you had Techtool Pro it would also likely say the HDD is failing.

Call Apple, tell them you are getting drive related freezes and bad sectors have started showing up on the drive.

They will tell you to ZERO out the drive, erase the drive and write zeros to it. Since this is the only thing that will get rid on bad sectors and have the drive reallocate them.

Likely the drive will be OK for a few weeks again, but it WILL fail if the bad sectors show up again (basically means the media on the drive is flaking off).

This was mine, it was replace due to the drive disintegrating and collecting 2 bad sectors a day -- it was less than 2 weeks after the last zero. And the errors went from 4k to 6k in that time.

---

Edit: bad sectors will happen, the drive should automatically reallocate them and has spares to do this ... start collecting a bunch, getting errors, and having hard system freezes is a decent warning sign of a bad drive.

I reinstalled OS X and still have problems. I don't know what else I can do :confused: My computer is just a few months old, could it be that the hard drive is faulty?
 
Yeah, it's certainly a bad drive. Since you have a blank OS anyways without any data, take it to an Apple store for replacement.
