HDD Problem!!! Help Please!!!

[Doraemon]

I bought a Maxtor 30.7GB (7200RPM, ATA-100)hard drive 2 weeks ago, saw the deal on Anandtech's Hot Deal forum. It has been working fine, but today, I found that it has bad sectors, a lot of them.

What is weird is that my WD 307AA (30.7GB, 5400RPM, ATA-66) also has bad sectors and was discovered a week ago, so I file RMA, and received the replacement with in 5 days.

My question is What can cause bad sectors to occur??? I did not shake the either HDD.

Is it possible that the Controller Card has gone bad and cause bad sector? Anything??

I also have question about how to fill in the rebate for that ATA-100 Card, so if you bought one, I need help on that too. On the rebate form where it ask for serial numbers, The section is titled "Serial Numbers: ", but when you go down, it says "Hard Drive Model Number____________", then "Ultra ATA PCI Card Model Number_____________", so do I fill in the model numbers or the serial numbers? How about both?



Thanks for any reply.

It looks like all they want/need in terms of numbers is the model numbers. I suppose you could give them serials too if you liked. No harm in that.

Now, why would you have two hard drives showing up with bad sectors? It is not uncommon to have hard drive errors when running overclocked chips (although I have heard less problems with that lately). But, those errors are not usually the cause of bad sectors, more likely they just cause crosslinked files and other non-physical errors. More likely, you just got two bum drives.

Sorry.
