NO, speed==40 may be too slow as I cannot grant that it will always fail with PIO and speed <=40. In case that the clock rate of your CPU just fits nicely, it may be that it by accident works. > How about a DVD at 8x speed? (Even faster than CD at 40x) This problem is not present with DVDs as they only support virtual sector size == 2048.
