I have a Premiere with 2TB WD20EARS (drive upgraded long time ago with jmfs-rev104.iso) that was recently updated, (infected in crxssi's terminology), to 188.8.131.52-01-2-746. Symptoms included frequent reboots in the middle of recording (5 segments of an one hour episode possibly recorded under 14.9.2), macro blocking (with timeshifts) and artifacts in recordings. Very sluggish menu response (I am using SD, have always used SD after flirting with HD briefly a long time ago). First I thought the disk was dying. Did kickstart 54, 57, passed (even extended and off-line). BTW, can anyone tell me the exact difference between extended and off-line? I assume one or both scans all sectors. I then put the HD in a PC and ran WD's diagnostic and "smartctl". Everything looks good. smartctl reports Raw_Read_Error_Rate 0 Reallocated_Sector_Ct 0 Seek_Error_Rate 0 Offline_Uncorrectable 0 Finally, I decided to forced an OS install with kickstart 52, as I read somewhere that a forced install will use an alternate partition (in case there is something wrong with the sectors that the OS sits on, but somehow drive diagnostics can't see). Recording quality seems better (less macro blocking). Still the reboots continue. Anyone from TiVo software development reading this thread, how about putting in a upgrade me last flag somewhere? touch /etc/config/upgradelast Some of us of a certain age are tired of living on the bleeding edge and no longer fond of alpha/beta releases. Same reason that I bought an iPad2 but never the 1. I perfer somebody braver and smarter to do the testing for me.
