I used to build PCs for a living.. I see some of you guys making some pretty awful mistakes when buying hard drives with sad consequences. 8 of my friends who I've known for at least 10 years currently work at a computer salvage warehouse. For your off-topic amusement: --- They take obsolete, dusty, and scratched up parts from old Compaq and HP servers and PCs. Since many HP and Compaq business customers HAVE to buy HP and Compaq-certified replacement parts (due to contractual agreements), they make a KILLING off selling these crappy parts to poor OEM-locked-in businesses. They also get other 'clones' (non-hp/compaq) and go through their parts to find working components, which can then be tested and 'compaq certified'. --- In this endless pursuit of working parts, they've conducted a poll of hard drives they receive and how many work. Here are the hard drives with the best results/unit: 1. Seagate 2. Western Digital 3. IBM/hitachi (apart from the 75GB Deskstars) Here are some bad brands: 1. Maxtor 2. Quantum (Do they even make hard drives anymore?) As some of you may know, it is damn hard to find hard drive failure rates. People have to rely on anecdotal evidence to support or decry a brand. I hope this will help you in a future purchase.
