Just to reiterate: "Fragmentation" on a Windows filesystem is _not_ the same as "fragmentation" on a unix file system. They are not comparable numbers, and do not mean the same thing. The only way to avoid fragmentation on a unix file system is to make every file you create equal to a multiple of the block size. And unix fragmentation does not degrade performance unless the file system is close to full. -- Bill Moran Collaborative Fusion Inc. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
