One of my disks died again a while ago. So I went to the machine to
replace the drive. But I forgot to write down which one had died. So I
started it up again. Now I had 7 disks again like before, but a
different drive was now "gone". So my RAID had only 6 out of 8 drives
and was "gone". Together with some 4.7T worth of data on it....

Next I went to the machine with a spare sata card. I removed the
drives from the ASUS U3S6 card, and put them on the old pci sata card.

By the time I logged in on the machine, the RAID had found 8/8 drives
and I think it had already started rebuilding.....

I now haven't had any problems with the drives in more than a week.

Performance of the raid has dropped from 600Mb to around 400Mb/sec,
obviously because the PCI card cannot handle 200Mb/sec of disk IO.

I'm open to suggestions for cheap highperformance WORKING PCIe sata
cards....

Roger.
