I also run the bechmarks with the gnop class invoked. It seems that the 'gnop -f nnn' option doesn't work, so that I couldn't observe any significant performance differences. I own several really nice broken IBM SCSI disks, but they are broken in such a way, that the mirrors break immediately after hitting the damaged areas. Maybe it's the better solution to run smartd from ports/smartctl and replace flaky disks asap. -- Christian Hiris <[EMAIL PROTECTED]> | OpenPGP KeyID 0x3BCA53BE OpenPGP-Key at hkp://wwwkeys.eu.pgp.net and http://pgp.mit.edu
