JJB <Barbish3@adelphia.net> wrote: These means that you have a mismatch between the devices and the ribbon connecting them to your motherboard. Most common cause is a UDMA66 hard drive plugged into the master connector on the ribbon and a UDMA33 CDROM. The messages is telling you the IDE hard drive controller is defaulting the ribbon read/write speed to the slower speed of the CDROM. Now this is not harmful to your hardware, but does deny your server the ability to utilize the full speed potential of your hard drive. This is easily fixed by moving the CDROM drive from the slave connector on the primary IDE controller to the master commenter on the secondary IDE controller on your motherboard. This also can occur if you have two hard drives on the primary IDE controller of different speeds. -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org]On Behalf Of samy lancher Sent: Wednesday, July 28, 2004 12:48 PM To: freebsd-questions@freebsd.org Subject: ata1: resetting devices ... Hello All, This morning I have seen the following log message on my FreeBSD 4.7 server. ad2: READ command timeout tag=0 serv=0 - resetting ata1: resetting devices .. ad2: DMA limited to UDMA33, non-ATA66 cable or device done. I would really appreciate if someone could tell me the cause for this message and is there something to worry about the server?. Thanks in advance.
