I had 4 HD crashes in 2 years. All of them are 80 Gig ATA 7200 rpm, two are Seagate and two are WD. Always virus protected. I have no idea what’s wrong. I have another 6.4 Gig WD 5400 rpm that works with no failure for 10 years. So is this because bigger drives rotating faster? Heating more? Any special measures to be taken to keep them safe? Then what about these new drives with hundreds of Gigs? Please guys share your experience with the HD reliability. How to pick a reliable one and keep it up and running for long? Thanks.
