Re: Too much hard drives failing



	Albert, thanks a lot for your answer.

	The only log i can trace back now is 
Device: /dev/sda, ATA error count increased from 11605 to 11610
because it's stored on our RequesTracker 

I have also some notes about
ATA: abnormal status 0xD0 on port 0xE407

This is taken from of those broken disks that's still attached on the
second port of one of the servers, i left it only to try figuring this
out.

I tried replacing the cables, etc. But the disks are really broken.
replacing them it works, maybe with no further errors.

Yes, i can remember about different error messages.

And i can only wait for it to happen again, if you need more logs

How did you work the 3Ware firmware thing?

Thanks a lot for the help

Pablo
