DU hang and "IOATAController device blocking bus"
Today this happened again, and I looked in the Console and saw that for at least forty minutes before I launched DU I was getting the message "IOATAController device blocking bus" every second or so.
After the restart this message has not appeared again.
I suspect (but at present only have this one event documented) that the previous times DU has hung, the "IOATAController device blocking bus" state also existed.
Googling "IOATAController device blocking bus" doesn't reveal anything very definitive, but impending hard drive failure is mentioned a lot, but usually in conjunction with other problems which I am not seeing.
I have Smartreporter running but it has not reported any problems.
I have four internal 1 Tb drives, and a Sonnet E4P card with four more drives connected, but these are only powered on to make back ups, and weren't on during this mornings hang.
I have not noticed any other problems, and Disk Utility reports no errors.
If it is impending HD failure, I can't see any indication of which drive.
I have at least three copies of everything so I am well protected against data loss but would like to sort this issue out.
Thanks for any help.
Mike
