I'm looking for e.g. Western Digital WD Blue Mobile 1000GB WD10SPCX.

I think it is a disk which has 4K sectors internally... But I don't
realy know it ;-)

It would be nice if I could use such disk...

I had a problem years ago to run a 2k MO- disk with 640MB. I didn't
look at it for a longer time for now... But this is an other thing, right?

Greetings
