Re: Debian support on newer 4K Advanced format drives (rather than 512 bytes)

[Ron Johnson <ron.l.johnson@cox.net>]

I think that the partitioning tool (fdisk, cfdisk, parted, ...) is 
what is really important.  That is because filesystems already use 
4KB block sizes.

Possibly also fsck.

There was a recent IBM DeveloperWorks article on this very topic.
