Linux

Recently, I bought a pair of those new Western Digital Caviar Green drives. These new drives represent a transitional point from 512-byte sectors to 4096-byte sectors. A number of articles have been published recently about this, explaining the benefits and some of the challenges that we'll be facing during this transition. Reportedly, Linux should unaffected by some of the pitfalls of this transition, but my own experimentation has shown that Linux is just as vulnerable to the potential performance impact as Windows XP. Despite this issue being known about for a long time, basic Linux tools for partitioning and formatting drives have not caught up.

Hm, how is LBA addresses specified exactly?

I thought it was specified as multiples of drive sector size, in which case addressing via LBA should always be aligned - but is it in reality always a multiple of 512?

Is there a difference between how LBAs in the MBR are interpreted, and how ATAPI interprets LBAs?
