I have seen this happen once when I tried to program my /dev/hdb to PIO
mode 4 when it only supported mode 3 (from the BIOS, not using hdparm).
Once I went back to mode 3, everything was fine. Problem is, using
MRBIOS only lets you set both drives to a common PIO mode, not
individually one to PIO-4 and the other to PIO-3.
