| About this blog: Computers hate me. They really do. Every time I try to do something unusual like add new hardware, something is guaranteed to go wrong. I decided to start writing about my constant problems so that someone else might benefit from my experiences - or at least laugh at them! |
I've been looking through my notes trying to figure out the trail of failures. The earlier Seagate 300GB SATA model saga is a particularly complex series of events. I think I've got it right now:
Of the original 4 x 300GB ST3300831AS drives purchased in late 2005, all 4 failed (one was DOA, one triggered a SMART event within 24 hours, the other two lasted 18 months longer). 2 were replaced with new drives by the retailer, 2 were replaced with reconditioned drives by Seagate. One of the reconditioned drives was faulty out of the box! This was replaced and then yet another drive failed.
Eventually the whole set of ST3300831AS drives (I think by this point they were all reconditioned replacements, none original) was "upgraded" by Seagate to 4 x ST3300620AS drives, but unfortunately they were also reconditioned. I had misunderstood Seagate's offer and thought they were supplying me with new drives, given the problems I'd been through. One of these "newer" drives failed in January 2008; I'd had enough so they were all shelved soon afterwards. Just for fun I recently put them into a server and checked their SMART values: all are showing uncorrectable read errors.
If I've done my notes correctly that brings the totals of wanting to buy FOUR drives to: 6 new drives, 6 recos, 7 failures. (A 58% or 175% failure rate, depending on your viewpoint.)
Don't forget the remaining recos are showing errors so if I dared actually use them they would probably eventually fail as well.
There's also the two USA based servers which had Seagate drives fail shortly after they were commissioned for me, mentioned in earlier posts.
WD is a bit easier: out of a total of 10 x 750GB WD7500AAKS / WD7500AACS drives purchased, two have failed, and were replaced with new drives. I also have 7 x 320GB and 3 x 80GB WD drives which are going fine (touchwood)
Hopefully this gives you an idea of the very bad luck I've had. The 750GB WD failures are somewhat expected because they work fairly hard in a database server, but the 300GB Seagates were installed in a desktop that hardly does anything disk intensive... apart from rebuilding RAID arrays every time I had to replace a failed disk. :-D
