You're right: I last looked at the IDENTIFY data about 7 years ago when those fields were defined; now they're marked as "obsolete". I guess the fields are still defined to keep old tools happy. Both atacontrol and camcontrol are still reading the IDENTIFY data and outputting the CHS fields even on ATA-8 drives, which I guess they shouldn't be. -- Bruce _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
