I installed a new IDE disk (wd1) on my 1.4.2 system and it's working less
than perfectly:

I see some similar messages for my ATAPI CD-ROM drive as well (on the
secondary IDE interface).

Is this a bug in the 1.4.2 IDE driver (has it been fixed in 1.5) or
a hardware problem?  Can I fix it in 1.4.2 somehow?

Thanks,
