I've added that to the list, and pointed replies there as well. > I've begun rec'ing these error messages: > > ad0s1a: hard error reading fsbn 141935 of 70848 - 71103 (ad0s1 bn 141935; cn 8 tn 212 sn 59 ) status=59 error=40 > > Got about 7 of these with varying values. > > I ran Seagate's diag utility and it reported only 1 bad sector (# 71099 ).

By the time you've got blocks going bad that the OS sees, the drive is in really sad shape. You should replace it with a new drive ASAP. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/consulting.html Independent Network/Unix/Perforce consultant, email for more information.
