Unless you run a `real' disk (*), almost any option you would specify is likely to have only bad effects. Don't use an option at all if you're unsure. (*) That is: floppy (there's an example in /etc/disktab), MO, good ol' ESDI drive etc., in short, everything that really uses a uniform number of sectors per track. Access to these drives might be improved by using the FFS optimizations, for modern (zone-bit recorded) disks, it will only be a pessimization. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
