>Wow... 512K is a HUGE cluster size. Are you sure that's right? Most networks I've worked with (NT or Novell) use cluster sizes ranging from 512 bytes to 16K bytes.

Hi Al,

I know it's huge (I'm not the NetAdmin person, either). I know it's right, however. I checked using the Win32 API call GetDiskFreeSpace(). It returns (among other things), the sectors per cluster and the bytes per sector. The return value I got for our local server was 512K (sectors per cluster * bytes per sector) / 1024.
