Old drive devoloped errs.

An old drive in my file server developed some errs when the power went out the other day, I have them remapped and it is working again. Is this a sign the drive is dying, or just that the power flux hurt it.

PS its from a system I purchased in '97, and outstanding 8Gb at the time.

I wouldnt be to worried about it myself, my dads pc did the same thing when we had two brown-outs in a row(except it wouldnt even boot) but reformatted and all is good and this was an old drive too.(12GB)
