Be aware that this is a somewhat dated article now, so when they say 'The 4K Sector Transition Begins' that probably should be read as '...has begun, quite some time ago.' And, when it discusses a single range of products from one manufacturer, the 'problem' (if that is what it is) is now rather more widespread than that.
I think if I was buying any 1T, or larger, disk, I'd want to check what the manufacturer said about it before I bought.
It also suggests that the problem is entirely confined to some other OS; you see occasional posts that strongly suggest that some people are having problems with Linux and 4K sector drives (not all that many though, and mainly when this issue was still relatively new...is that because the problems are caused by software that pre-dates 4K sectors, is it because some people have made a mess of the partitioning (perhaps following dated tutorials) or do some people have sub-optimal performance and never realise/report it, or is something more complex going on...I'll pass on that, but the idea that because your are using Linux, necessarily you will not have any problems now seems a little complacent or over-simplified).
OTOH, the Developerworks article, and, in particular, the Tejun Heo link, which I hadn't read before, seem pretty good.
