Booting problems on wd1a *UPDATE*

[Black Berry <blackberry@kyuzz.org>]

I've changed the disk, all doesn't works as before.
I catch also the same error at boot time:  stat(hda1:/./sys): Unknow error: 
code 20

I think there's an hardware problem or an incompatibility.
After this i've tried to use the same disk on an IBM Netfinity P4.
All boots correctly :)

Tnx to all the people helped me.
I hope is not a compatibility problem, but probably something bad on IDE 
channel (maybe on cd0a)

bye
