Do it! When I refeormatted my drive from 512 to 1024 byte sectors, I gained about 15% extra space and about 2x faster speed up (using the speedometer program). You will need the scsitools available on sonata (sense and one other). Be careful, as I irreparably damaged one drive by using the GUI version of the program without first saving the sense file.
