Sanyo Cdrw Drive Problems

My second cdrw drive is a sanyo 40x write. The problem is I have it on my second machine, running windows 98SE on an AMD K62 CHIP (remember the old super 7’s? lol), anyway, sometimes Nero will recognise it as 40x and write at 40x, and then stop about 90% into writing at that speed, and when I CTRL ALT DEL and restart Nero, it then recognises it as a 2x write CDRW drive…lol, it writes correctly at this speed.

The drive is recognised correctly by windows, tho i’ve not updated my BIOS for the motherboard. Could this be the cause, or is it likely to be something else…?

thanks a lot peepz…
