Hi Neil, My original email may have been eaten: as it did not appear on the list, nor did I get an error message back. So perhaps there was a problem with the attached files. I will resend the attachments one at a time in separate emails. Cheers, Gavin [begin original] Hi Neil, Your help (or anybody else's) would be greatly appreciated, yet again! This morning, I noticed my system was extremely unresponsive, and that there were clicking sounds coming from one of my 5 hard drives. Also that there was excessive disk I/O even for trivial things like bring up a directory window, and lots of ata3 errors being reported to the system log. These symptoms were mostly during a raid check process. Somewhere along the way, I seemed to have lost my swap partition! So I did some extensive investigations, which took most of the day. My notes were created in OpenDocument format using LibreOffice, but I have converted them to txt format for the include - but I can supply the ,odt file if requested. I Have included 2 files: my notes: raid-notes-20110407a.txt selected log entries: messages-gcf-20110407-ATA If there are some additional diagnostics that might prove useful, please let me know.
