We have a Xylogics 754 VME hard disk controller with a Seagate Sabre 9720 1 GB drive on an SGI PowerSeries. Unfortunately this doesn't work. We have had the disk, cables and controller replaced several times but it still doesn't work. What happens is that sometimes bits get flipped when writing files. This is quite reproducible. When copying 25 2.5 MB files, about 5 to 15 copies will have errors in them. The OS does not detect this. I tried putting the controller in another slot, but this did not improve the situation. There is a virtually identical hardware configuration on another PowerSeries Iris at this university which works perfectly. Has anyone seen problems like these before?
