Unless I’m doing my math wrong 57,000 bytes is 57K or 0.057MB. That’s not too bad.
I will say that often once you see bad sectors starting to pop up more may follow. Consider doing a scandisk weekly for two or three weeks (if you have that time under your warranty) and see if more follow. If they do then something is definitely squirrely with your hard drive and you’ll have a better chance at getting it replcaed for no charge.
You should look at your guarantee & see what it says or call the people who enforce it. A three year old HD won’t be made today probably so they would have to put in whatever HD they have today. Anyway, call the people behind the gurantee (are they still around?) & see what they have to say & let us know.
I have used drives with sector reports like that for a couple years safely but as the person said above, if they keep rising you should get a new one.
I’ve dealt with lots of drives over the years, both notebook and desktop, and even small, non-hidden media failures like the ones you describe are often the precursor of Very Bad Things to come. I would make the point to Compaq that reliablity of your notebook data is super critical you cannot afford an incipiently flaky hard disk and that it must be replaced. I have been in your shoes in the past with desktop systems (ie small cluster failure on Compaq system) and I have always gotten them to replace the drive.
As a second suggestion you may want to use this an oppy to get a bigger drive and simply chuck the smaller one. 20 - 30 gig 2.5 note book drives are now in the 120 - 160 range at some vendors and Compaq notebook hard drives are usually fairly easy to access and replace.
