Opening up the export cases revealed that the fan was dead and clunking. I think the dieing fan lead to the odd noises, and a disk overheating issue might have been leading to the recent crashes. A replacement fan has been installed and the drive case was left open to provide more airflow. Hopefully this fixes the problem. So far things are performing well . ___end___ Wed Jul 7 20:05:37 GMT 2010 CHIP End Patrol Wed Jul 7 20:09:57 GMT 2010 MKIV Start Patrol Wed Jul 7 20:10:14 GMT 2010 CHIP Start Patrol **PSPT PROBLEM COMMENT BY BEN**: Wed Jul 7 20:15:16 GMT 2010 Communication error between SPARC and PC in an exp command.

It appears the system is functioning well, and all of the data and permissions are restored on the new disk. Unfortuantly the data taken this morning is only on the old disk and will not make it into the archive. I am running a test observation now. ___end___ PSPT COMMENT BY BEN: Thu Jul 8 03:31:05 GMT 2010 Test took a little longer then I expected I forgot the camera controller is on a timer that turns the system off ___end___ Thu Jul 8 03:40:58 GMT 2010 CHIP End Patrol PSPT COMMENT BY BEN: Thu Jul 8 03:43:04 GMT 2010 I think everything is working, but it is to late in the day to observe so we will see tomorrow. ___end___ Thu Jul 8 03:44:15 GMT 2010 MKIV End Patrol Thu Jul 8 03:48:44 GMT 2010 MkIV 00_21.rawmk4 01_55.rawmk4 03_24.rawmk4 18_35.rawmk4 20_42.rawmk4 00_24.rawmk4 01_58.rawmk4 03_27.rawmk4 18_38.rawmk4 20_45.rawmk4 00_27.rawmk4 02_01.rawmk4 03_30.rawmk4 18_41.rawmk4 20_48.rawmk4 00_30.rawmk4 02_04.rawmk4 03_32.rawmk4 18_44.rawmk4 20_51.rawmk4 00_33.rawmk4 02_07.rawmk4 03_35.rawmk4 19_08.rawmk4 20_54.rawmk4 00_36.rawmk4 02_10.rawmk4 03_38.rawmk4 19_11.rawmk4 20_57.rawmk4 00_39.rawmk4 02_13.rawmk4 03_39.rawmk4 19_14.rawmk4 20_59.rawmk4 00_42.rawmk4 02_16.rawmk4 03_40.rawmk4 19_17.rawmk4 21_03.rawmk4 00_45.rawmk4 02_19.rawmk4 17_30.rawmk4 19_20.rawmk4 21_05.rawmk4 00_48.rawmk4 02_22.rawmk4 17_33.rawmk4 19_23.rawmk4 21_08.rawmk4 00_51.rawmk4 02_25.rawmk4 17_36.rawmk4 19_26.rawmk4 21_11.rawmk4 00_54.rawmk4 02_28.rawmk4 17_39.rawmk4 19_29.rawmk4 21_14.rawmk4 00_57.rawmk4 02_31.rawmk4 17_42.rawmk4 19_32.rawmk4 21_17.rawmk4 01_00.rawmk4 02_34.rawmk4 17_45.rawmk4 19_35.rawmk4 21_20.rawmk4 01_03.rawmk4 02_37.rawmk4 17_48.rawmk4 19_38.rawmk4 21_23.rawmk4 01_06.rawmk4 02_40.rawmk4 17_51.rawmk4 19_41.rawmk4 21_26.rawmk4 01_08.rawmk4 02_42.rawmk4 17_54.rawmk4 19_47.rawmk4 21_29.rawmk4 01_11.rawmk4 02_45.rawmk4 17_57.rawmk4 19_53.rawmk4 21_32.rawmk4 01_14.rawmk4 02_48.rawmk4 18_00.rawmk4 19_59.rawmk4 21_35.rawmk4 01_17.rawmk4 02_51.rawmk4 18_03.rawmk4 20_09.rawmk4 21_38.rawmk4 01_20.rawmk4 02_54.rawmk4 18_06.rawmk4 20_12.rawmk4 21_41.rawmk4 01_23.rawmk4 02_57.rawmk4 18_09.rawmk4 20_15.rawmk4 21_44.rawmk4 01_32.rawmk4 03_00.rawmk4 18_12.rawmk4 20_18.rawmk4 21_47.rawmk4 01_35.rawmk4 03_03.rawmk4 18_15.rawmk4 20_21.rawmk4 21_49.rawmk4 01_38.rawmk4 03_06.rawmk4 18_18.rawmk4 20_24.rawmk4 21_52.rawmk4 01_41.rawmk4 03_09.rawmk4 18_20.rawmk4 20_27.rawmk4 c19_44.rawmk4 01_44.rawmk4 03_12.rawmk4 18_23.rawmk4 20_30.rawmk4 c19_50.rawmk4 01_47.rawmk4 03_15.rawmk4 18_26.rawmk4 20_33.rawmk4 c19_56.rawmk4 01_50.rawmk4 03_18.rawmk4 18_29.rawmk4 20_36.rawmk4 01_53.rawmk4 03_21.rawmk4 18_32.rawmk4 20_39.rawmk4
