What else should be in the contents to help you guys pinpoint the problem? Should I include the 50kB+ contents inside this message, or is posting a link better? Can someone please suggest what to try to pass to kernel at boot to work around, so the drive doesn't die? (If I absolutely had to, I would try to recompile the kernel -- I haven't done that in a few years.) Thanks a bunch in advance, John
