My question is: It is safe to use softupdates + write cache + ata tags (IBM disk)? I read someware that it not safe to use softupdate + write cache (without ata tags) and if it is not safe why FreeBSD 5.0 ships with them enabled? Thanks very much, Nuno Teixeira -- /* PGP fingerprint: C6D1 06ED EB54 A99C 6B14 6732 0A5D 810D 727D F6C6 */ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
