Ok. I'm now adopting the idea of always cold booting my system.

Ok. I just plugged and replugged it in the hope that it would be
identified after replugging.

Well, I tried the patch. The first time I tried it, it worked and I was
quite happy. I then unplugged the drive and then I inserted it a second
time, to see if it behaved the same way it did in my old notebook (which
you may remember that the drive always work there). It unfortunately
didn't, which led me to think that it was only one of those "statistical
noises".
Anyway, I cold booted my system and tried the same process again and,
this time, it didn't work. Here is the log of the failure and below it
are the differences between it and the success case.

BTW, I don't have Windows 2000 installed anymore (I needed the space for
some data), but now I can install it again and if you want any logs from
Windows 2000, I can surely install it again, if you wish to see another
batch of logs from Windows 2000.
Thanks, Rogério.
