[wplug-bsd] Fdisk? formatting ext2 partitions as ufs

[Brandon Kuczenski]

I need some help formatting my disks.

Since I am now set to reformat my ext2 partitions as ufs, I need to figure
out some kind of deal with disk geometry.  I'm using /stand/sysinstall as
an interface to fdisk, though I would be quite happy to just use fdisk
(but I don't know anything about it).

So I was going through, and it gave me a warning that the geometry
specified for the disk was incorrect, and I should manually set it.  But I
don't know anything about my disk's geometry -- I was relying on fdisk to
figure that out.

Now I'm happy to just blunder on through this thing, except for the
following problem: I have two slices on this disk, both formatted ext2.
What I've done so far is copy all the data from the second slice onto the
first and umounted the second slice.  Now I want to format it, but I'm
afraid of spoiling the data on the first slice if I screw something up.

So: if the disk is already partitioned correctly but I'm formatting it a
slice at a time, do I need to worry about the geometry?

And will a 'dedicated' format prevent me from accessing this disk from
another OS, should I need to?

TIA,
