Default All abot Hard Drive Formatting, Cylinder Size and Block Size

There's a lively (for the Natami board) discussion going on over at the Natami Forum about "hard drive" tuning for compact flash cards. The suggestion is that running a CF card with block sizes of 16k increase speed and longevity.

Now, I was never an early adopter of hard drives, so my experience of formatting and partitioning is using cfdisk and busting out a few partitions to slap linux or windows on - IE I never ever mucked around with block sizes, cylinders or any of that. I attempted some cursory googling and came up short or with "Just run the wizard, type in your number and let windows do the rest!"

So, having read through the thread, I fired up HDInstTools off my trusty Amiga911 disk and decided to muck around with a 4G CF card I have. HDinstTools lets you adjust setup on 4 things: Cylinders, Blocks per Track, Heads, and Block size (Oh, and interleave and auto park). If I adjust Block size by itself to 16k, the "size" of my disk increases to 122Gb or so, a tad outside the actual capacity. Obviously the 4 things relate to each other, but I'm not positive how. I am handy with numbers, but I'm not sure what the ratios are.

Can someone explain how all this stuff relates to one another? Or offer up a good link where I can RTFM?
