Self repairing hard disk?

By etord ·
Hi, my abused asus laptop's HD suddenly failed weeks ago, without s.m.a.r.t. warnings. Horrible click ang clank noises came out when trying to access heavily damaged sectors. Thousands of bad sectors occurred over the whole drive with almost regular intervals, always getting worse. Then, while left scanning the surface for a file (5 days and nights, continuously, with click and clank and overheating) it suddenly began to work fine again. All bad sectors gone, everything worked perfectly. Only, on boot, s.m.a.r.t. warned "bad, backup and replace". Then again, weeks later, after another emergency shutdown due to overheating (always my fault), even the smart got ok.
Now, while i'm waiting for the day IT will state "I'm alive", can anybody suggest me if it's ok to keep on using it or, if not, how to explain what happend to tech support (warranty still valid!), since there's no evidence of the problem occurred?

Humm the first hint at "Danger! Will Robinson" should have been the click noises.

under warranty? send it back. Let them muck with it while you get a new one.

If I buy myself a new one and the problem is not the hd but other (like m.b., controller, whatever) it's no good. But my problem is: even if i send to techs the whole pc, i've no evidence that the hd had a major failure, since now everything works great. They would just send it right back to me as it is, i think. But everyone keeps telling me that it's bound to die soon or later. Guess i just have to wait that day hoping my warranty won't expire.
Thanks a lot.
Regards

It is a risk of losing the data on the drive if you continually use the drive sooner than later it will die,before losing the drive backup the data on drive then continue to use at own risk,as far as IT goes the drive is on the blank which will not effect the warrenty,be honest if you have too because you have done no harm,if you have been instructed to not use the drive that is another question of integrity

So you think, even if mechanical noises, bad sectors, "smart bad, backup and replace" warning, they all disappeared, drive diags were ok and I've been using the hd without problems for 1 month, the hd is doomed anyway?
But, correct me if i misunderstood, would you suggest me to keep using it until it breaks and eventually send it to techs or send it now, describing what happened even without evidence?
Thank you

First thing to do is download the HDD makers Testing Utility and test the drive for any faults.

This should be included in the makers manual or on their Web Site for your particular model what Brand of HDD is actually used.

But before you do anything at all BACKUP ALL YOUR DATA! The problem could be a faulty HDD or it could be a bad installation of Windows or even maybe the way that you are using it but the one thing that I'm certain of is the cost of recovering DATA off a dead HDD which is horrendously Expensive so it isn't worth running the risk of loosing your Data.

If the Drive Checks out as OK I would still return the complete unit for a Warranty Service at the very least but their first action is to wipe the HDD and perform a Clean Install of Windows so you have to have your data Backed Up or you'll loose it completely.

I tryed, as you suggested, to use the Hitachi recommended Drive Fitness Test diag, but it didn't work (error while scanning ide ports...). My drive is an IBM icn25n080atmr04-0 but I don't know wich model is it because there's no info on the brand's site. So maybe it's one of those listed as incompatible with the diag program but who knows?
Back up went well and I personally formatted and reinstalled win xp.
My real problem is how to have the hd replaced now that even s.m.a.r.t. check's ok? Do you know any other diag program that can exploit a lurking misfunctioning?
Thanks

Many thanks to you all, I really appreciate your suggestions.
So, since data on hd was safely bak'd, my only concern (amazement apart) was this physical failure that occurred and disappeared (even deadly clicks!), that might be caused by some other motherboard hw problems (?). In that case, even buying a new hd myself would be a mistake.
I tryed as you suggested to use the Hitachi recommended Drive Fitness Test (my drive is an IBM-hitachi icn25n080atmr04-0 but i couldn't find out what model - some travelstar?), it's a small diag running from dos boot diskette, but it didn't work (error while scanning ide ports...).
I will follow your suggestion and send the whole notebook to techs, hoping they'll exploit the real problem. But, I'm afraid, as they'll see the hd is ok they won't do very much.
Thank you again.

Just demand that it be replaced. SMART isn't the be all and end all of HDD fitness I've seen plenty that have just turned up their toes but the SMART doesn't monitor any potential damage. The IBM DeskStars where notorious for doing this and I've got a couple here that just plain & simple do not work reliably you can load Windows and even run it for a day or two and then you loose everything but the SMART insists that the Drive is working properly.

You want to get it replaced prior to the Guarantee expiring or at the very least make the Service Department Make a Formal Note of the problem so that if it does fail after the Warranty Period you have a come back on them and remember that Hitachi HDD have a 3 year Warranty not a 12 month warranty like the makers of your NB may seem to think.

You have got to be kidding me! NO It is not ok! Get your data off that drive now! Get a new drive. Warranty or not!

That thing has been warning you for how long? Weeks. If you loose your data it's your fault!
