Write cacheing is automatically enabled if tagged queueing is enabled and supported by the disk, so I doubt you're seeing any improvement at all. /* enable write caching if allowed and not default on device */ if (ata_wc || (ata_tags && ad_tagsupported(adp))) { if (ata_command(atadev, ATA_C_SETFEATURES, 0, 0, ATA_C_F_ENAB_WCACHE, ATA_WAIT_INTR)) ata_prtdev(atadev, "enabling write cache failed\n"); } DES -- Dag-Erling Smorgrav - [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
