I've bought lots of HDDs over the past 10 years or so and from time to time you run into a bunch of bad drives. I had some bad Maxtors, years ago and a couple of WDs in the very early days...but for a time, the last 5 years or so, I've been pretty lucky. I generally buy the cheapest ATA drives and I haven't had any real bad issues. But lately I've started to notice a trend. I have about 5 Hitachi drives, 10 Seagates, 2 WD and 4 Maxtors. Of them all, I've had 5 issues...all with the hitachi drives. 2 connectors broke...which I'm sure that I'm partially to blame for (SATA crap connectors + force = saddness), but again, only the Hitachi drives had an issue. another drive started crapping out with write errors etc...I returned that...then 2 more died with "excessive shock" errors. I'm glad they are still under warranty...but I'm done with Hitachi drives...that's for sure.
