I'm using TI8 (yes, I know) I have been successfully imaging my hard disk to an external drive (over FireWire 400). I now want to image the hard disk to another external drive (one I have just bought). I want to initialise my new external disk optimally, so my questions are: a) does it matter what cluster size (4K to 64K) I use for the new external disk? b) can TI8 image my hard disk to the external disk, regardless of its cluster size (my internal hard disk has the default 4k clusters)? c) what's the best cluster size to use of the external disk, for speed of imaging? TIA I .
