[CentOS] PATA Hard Drive woes

Well I'm geting there slowly but surely.

This home-built server machine is using hard drive caddies.

I've taken my working backup drive from the caddy (secondary 
master), and replaced it with a small GB test drive.

The problem was originally with the drive connected to the 
onboard IDE primary channel being intermittently 
autodetected at boot time.

I have now swopped the IDE ribbon cables, so the cable that 
was connected to the primary IDE channel is now plugged into 
the secondary channel onboard IDE socket, and vice versa for 
the secondary ribbon cable.

Now when I reboot the machine the problem of drives not 
being detected now appears on the secondary channel, and the 
ATA drive and CD/DVD-ROM drive are detected OK on the 
primary channel.

I have also replaced the IDE ribbon cable for the channel 
that was originally connected as primary.

So it appears the onboard IDE controller is working OK, and 
the problem appears to be from the IDE ribbon cable, to one 
of the HDD caddies.

Any suggs please?

Kind Regards,

Keith Roberts

In theory, theory and practice are the same;
in practice they are not.
