What would cause these hard disk errors?


I have a Dell laptop with nearly 3000 errors on it as reported by the Dell diagnostics thing. I also used the Samsung Hutil program to try and maybe zero the drive. I heard someone else say it worked for him but it would not let me do it, it failed the test apparently. At the moment I have just made a partition of 10Gb with the Mandriva installer and I am using that. The errors start just after the 10Gb mark. I am resigned to the fact that there is nothing I can do but buy a new hard disk but I don't want this to happen again. It's less than 2 years old and has not been damaged or abused or anything like that. I remember it crashed a few times and I had to whip the battery out to turn it off but other than that I don't know. I've heard heat and dust can cause damage to it but it is not subjected to any intense heat or dust. It could have been faulty to begin with. Is there any chance of getting a replacement from Dell, does anyone know?

I'd contact dell and see if your hard drive is still under warranty through them. If not try contacting the manufacturer of the hard drive. I know those things are not dell branded hard drives. Usually they come with a 5 year manufacturer warranty.

It comes as a great shock to many people that moving your laptop while the hard drive is moving is abusing it. While rotating, the G tolerance of the drive drops dramatically, and the heads can contact and damage the surface.

In any case, my experience is that non-stationary drives have a life expectancy of about 18 months, so you are right in the ball park. If you are getting a replacement, consider a Hitachi Travelstar. They have higher G ratings and quieter operation than most any drive I've used. They also have a much higher load/unload rating, so you can spin them down more frequently when mobile, to avoid damage.

My last Hitachi lasted 2 years. *sigh*.

One secret is certainly to avoid moving the system when the drive is spinning, and if you MUST move it, don't tip it; keep it in the same orientation it was in when resting on the tabletop (or wherever) when you were using it.

I threw my running dektop out the (open)window once and it worked for another 2 years.

Get a Toshiba drive

Well, thats news to me. I certainly would not have expected to damage it by moving it. It is a Samsung Spinpoint so I will see if I can get a replacement from them, at least find out if the drive is still under guarantee. Thanks

A spinning hard drive platter is a gyroscope. It will resist changes in its orientation; this is just basic and inescapable physics. The platter is built to be as light as possible and as stiff as possible to minimize this effect, nonetheless it MUST deform when its orientation is changed while it is spinning. Given the high data densities and the fact that the head travels within microns of the surface of the platter, any deformation pretty much has to cause a head crash.

The drive is built to tolerate this, but it is still a very bad thing to have happen.
