I used to have it this way... 4 Parallel IDE i/f's each i/f's master was a WD800 in a RAID5 each i/f's slave was a WD2000 in a RAID5 I am removing the WD800 array and moving the WD2000 array to masters; so there are no slaves. However, in the process, one of my WD2000's seems to be having problems. It seems to work as a slave device, but not as a master. I have tried many combinations of interfaces/cables/power/etc. I can even put it on an i/f on it's own as a slave device, and it seems to work (the device name changes to show that it is actually the 2nd device on the channel - ie when testing it on the motherboard, it shows up as hdd, not hdc). I am not sure what to do. Can I just make it a slave device? How will that effect performance? Any ideas? Max.
