[gentoo-user] Re: IDE/USB problem : not both disks recognized on same IDE channel

[Rohit]

The results are encouraging !
I am able to see both disks on at least 1 IDE channel, so we have surely
fixed the problem with the kernel.
Will check cabling etc for the other IDE channel.

Thanks very much !
