Hang on -

IIRC, it's only yes to that question if the drive itself advertises that it's 4K sectors.

I believed that if it uses 4K sectors, but *advertises* that it uses 512 byte blocks, then it goes to crap pretty quickly. (witness Netapp FC luns, many SSD's etc)

Is there actually a fix to allow manual setting of ashift now that I missed, or are you referring to the 'best case'?

Cheers,

Nathan.
