So do we, except they're both the same for Advanced Format drives: # camcontrol identify /dev/ada1 ... device model WDC WD10EARS-00Z5B1 ... sector size logical 512, physical 512, offset 0 I don't know if Linux has a quirks list that 'corrects' the physical sector size? -- Bruce Cran _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
