>From what I've managed to discover, rightly or wrongly, here is how I see it:
* it appears as if the most recent revisions of some models of the WD Green 
'EADS' and newer Advanced Format 'EARS' drives have some problem which puts me 
off using them for now (see links in first post + google). They also appear to 
have disabled user setting of TLER.
* Some Seagate 1.5TB models, like the one discussed in this discussion, appear 
to have low user ratings, and many of the user comments mention clicking noises 
& failures.
* Hitachi models I don't know enough about yet, but I would rather avoid using 
5-platter models like one of the 2TB models.
* Samsung have a 3-platter 1.5TB model (HD154UI), which seems to have quite 
high user satisfaction levels and you can set the error reporting time, but it 
will not persist after power off.
* Samsung also have a 4-platter 2TB model (HD203WI), which appears to have 
excellent user  ratings, and no DOAs listed, but as there are only a small 
number of ratings left (<20), it is too early to make a judgement, but early 
data seems to be very promising. 

Based on the above, and with further reading required, at this stage, I will 
almost certainly be choosing the Samsung HD154UI.

But let's keep an eye on the HD203WI, because when the price drops a bit 
further and if more positive data appears, this might be a great model to 
consider for those people replacing / upgrading drives.

And regarding your reply here to a comment from Bob on the Seagate model 
discussed:

Bob was joking around about the Seagates :)

And newegg don't list reviews/ratings by default in worst to best order -- I 
posted that link using that order so that it was easy to see the kind of 
problems people were commonly listing. The things one wants to see before 
choosing.

Again, humour alert from Bob :)

Cheers,
