Rob,

Thanks for the great reply. I have all three of those risk factors, including removal of the ide cable several times for different drive upgrades. I also had gibberish for drive ID in the serial log intermittently. I haven't tried the serial log recently. The last time I had it apart, I looked at the solder joints, but without a magnifier, and didn't notice anything obvious. I'll post a serial log if you think that's appropriate.

Thanks again,

Jim
