Hi


More than a month ago i bought 4 Western Digital WD15EARS (1.5 TB) which 
are (AFAIK) the first general/commercial available 4k sector SATA-HDDs.

Unfortunatly the HDDs lie about the 4k physical sector size and the most 
prominent drawback is a worse than abysmal delete performance.
("Normal" Read & Write-performance is OK)

So if i wanted to (re-)mkfs the filesystems what would the correct 
parameters be?

Kernel/Userspace is pretty recent (Debian-SID):
mkfs.xfs version 3.1.1, kernel v2.6.33, util-linux 2.16.0
Not that that should matter when the HDDs lies.
