Drivers, kernel recompilation, etc... Thanks. There's only one way, you have ata driver compiled into kernel or not. The only tuning you can do is described in ata(4) manpage. This particular error can be caused by bad cable/connection, dying drive (yesterday my 37GB IBM died after several weeks of emitting such messages) and buggy firmware/drivers. Almost anything. Better be cautious and back up your important data 8-), because I did not. -- Vallo Kallaste kalts@estpak.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
