My XPS M1710 notebook is getting temperamental about starting up. I hit the power button, the power light comes on, but the disk light sometimes doesn't.

I have to press the power button several times before the disk light comes on and the system boots up. After that, everything is fine.

I ran the diagnostics and got the error code 2000-0146. I know this normally means that the disk drive is toast, but mine works fine as soon as it boots up.

Is there some way I can fix this or is it best to replace the hard drive?

And will replacing the hard drive solve the problem?

Thanks
