Probably OT, but I'm getting the above error message more and more frequently, followed by the machine seizing up. (1) Is this definitely a sign of a dying disk? (2) Is there any possibility of an hdparam change improving matters? I'm running FC-1 with kernels 2.6.4 and 2.4.25. [I have the impression that I get the error slightly more often with the 2.6 kernel, but that could be an illusion.] Any advice or suggestions gratefully received. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
