RE: Installation issue - Newbie

[Jamin Collins <JaminC adapt-tele com>]

This is most likely due to the controller that you have the drive connected
to.  Linux does not currently have stable support (to my knowledge) for the
UDMA66 mode or controllers.  If you connect a UDMA66 drive to a non-UDMA66
controller it will do one of two things.  Either the drive will not be
detected, or the drive and controller will auto-negotiate to a lower mode
such as UDMA33.  As for the reason I suggested he use the Maxtor utility to
force it to a lower mode, I have a Maxtor 40 Gig drive (same as the one in
question).  I have tried this drive with several different controllers.
Under no circumstance was I able to get the drive to auto-negotiate to a
lower mode.  In ever test the drive was not detected when the controller it
was connected to was a non-UDMA66 controller.

If linux not yet supported UDMA66, why my Quantum Fireball lct10 15 UDMA66
works without any problem?

    I verified that the Disk drive I have is indeed a UDMA66 drive.
    So, how can I install Red Hat Linux on a machine with just one
    drive which is UDMA66.

    If I skip the drive during installation, I get an error that there is no
    device to create a file system.

Thanks,
Ramesh
