is there a way to check if its failing?

No, but there's a way to check if it's not failing. Open Disk Utility, select your hard drive (the one that's not indented) and take a look at the bottom where it says your S.M.A.R.T. status. If it shows an error, your drive is failing. If it shows verified, your drive may still be failing, but just not officially reporting it. See where the reasoning breaks down?

also would i be able to get it replaced?

Absolutely. Your drive is covered by warranty. Your data, however, is not, so back up early and back up often.

It's a $90 product that was last updated in 2004...

Wow it's been that long since it was updated, I knew there was a reason why I think that Steve Gibson guy on Leo Leporte's Security Now podcast is full of it. But regardless of the high price or old age of Spinrite it has actually worked for a guy I know.

That's the noise my MacBook made before the laptop HD failed on me. Definitely start backing up everything if you can. My MacBook was still under warranty at the time to Apple replaced it for free.

thanks a lot for the help guys...few more questions tho

1) how much time till it does fail (if it does)
2) what caused this?
3) is a time machine backup sufficient?

thanks again!

  1. Anywhere between now till maybe a week from now. Too many variables to give an exact. For me, it lasted around an hour or two.
  2. Could be a hardware defect of the HD. Maybe a drop. Maybe another piece of hardware had a bad interface (not overly likely, but ...)
  3. Time Machine likely has enough backed up. I don't use it much so not sure about settings for HD cloning and if you only have certain folders being backed up. Someone else can likely give a more definitive answer on this.

3) is a time machine backup sufficient?

Yes. However, a cloned backup is more convenient. If you've got everything backed up in Time Machine, use Carbon Copy Cloner to make a cloned backup. Since Carbon Copy Cloner is very read-intensive, it may cause your drive to fail in the process of making the backup, but if it doesn't, you don't have to fiddle with restoring your Time Machine backup after the fact. It's not terribly hard to do so, but CCC is easier.

Your drive is almost certainly going to fail at some point in the near future, so it's only a matter of when.

I'd try Data Rescue 2, it has a clone function, and then you can recover files from the clone so it keeps use of the original drive to the minimum necessary.

Carbon Copy Cloner would probably work, but it might stop because of errors if it comes across damaged sectors, since it's not designed for damaged drives.

Are you trying to push it over the edge or are you trying not to?

The drive is wearing out prematurely. All drives will come to behave like that sooner or later, just most considerably later than that. Just using it will destroy it. Heavy use will destroy it faster than light use.

When the drive fails altogether, you will hear it trying to spin up over and over again. If the computer is running at the time, it will freeze (or possibly kernel panic). When you next go to start it, instead of the Apple logo after the startup chime, you will just see a question mark since it won't be able to find a bootable drive.

If you can hear the drive failing, any use at all (usually) will worsen the damage. That's why cloning the drive (with either Data Rescue, Carbon Copy Cloner, or the UNIX dd command) is good, since it copies as much data at possible as quickly as possible.
