Subj:   Re: Why does size of table increase in multiples of 512 bytes
 
From:   C R, Visakh

Hard drives traditionally used to have 512 bytes per sector. What I have read is that during 'old' days, when even an MB of data seemed to be too large, disk makers adopted the 512 bytes strategy. This meant that the smallest amount of data consumed was 512 bytes. So, even if the file is smaller than that, the maximum capacity consumed will be 512 bytes.

I have seen reports talking about shifting from 512 bytes to 4 KB ( en.wikipedia.org/... ), but not sure whether they have gone mainstream yet.


Thanks,

Visakh
