Subject: [9fans] tiny fix for Eric's patch: 9pcfs on 4G IDE disks

If any of you plan to use >4G disks with the nice patch
made by Eric Dorman to run 9pcfs on IDE disks:

Replace in plan9pc/devata.c
	long	atasize( Device *d )
	{
		Drive	*dp;

		dp = d->private;
		return (cp->cap * 512) / RBUFSIZE;
	}
with
	long	atasize( Device *d )
	{
		Drive	*dp;

		dp = d->private;
		return (dp->cap / RBUFSIZE * 512);
	}

Otherwise, an overflow leaves the device w/
just 1k blocks or so.

After changing this, I'm running it smoothly
with the device "ch0fh2" (two 4G ide disks).

PS: Thanks Eric for your nice patch
