win98: DVD-ROM doesn't work with HDD

dvd_ide · 11-23-2003, 03:45 PM

DRIVES:
Hitachi GD-2000 DVD-ROM
Quantum TX series 5.25" HDD
Maxtor [boot drive]

The machine is a HP Pavillion Pentium-II 350 MHz;
top to bottom, the drive cage looks like this:

(top) DVD-ROM
(mid) 5.25" Quantum HDD
(lower) floppy
(lowest) boot drive

and the IDE slots on the motherboard are near the base of
the cabinet, 6" or so below the boot disk.

NOTE: the cabinet and drive cage have physical limitations,
these drives cannot be mounted any differently!

The Primary IDE has the boot drive, jumper=master, and
is connected at the end of the ribbon cable. There's no
place to mount anything below this drive, so the middle
ribbon connector goes unused.

The Secondary IDE has the Quantum TX HDD attached with the
middle ribbon connector and the DVD-ROM attached at the
end ribbon connector. The ribbon cable is regular length.

The problem is the DVD-ROM is not accessible from win98
whenever the Quantum HDD is connected. On the boot disk,
the DVD-ROM driver is installed properly and gets used
when win98 sees the DVD-ROM. So far, the only time the
DVD-ROM works is when the Quantum HDD is NOT connected
(and the DVD-ROM jumper set to Master or CS); in this case,
the DVD-ROM is accessible as "D:"

For the DVD and Quantum HDD, all combinations of Master /
Slave / Cable-Select jumper settings (except M+M, S+S)
have been tried. Some combos cause the machine to hang
at an early stage during boot; with the other combos, the
Phoenix BIOS always sees and correctly reports all (3)
drives, but only the Quantum HDD (and the boot drive on
the Primary IDE) are accessible from win98; the Quantum
HDD on the Secondary IDE always gets assigned as "D:"

When win98 boots OK, the Device Manager always shows a
yellow exclamation next to the Secondary IDE, and the
error information is not useful. A CDROM (not DVD)
is always present as a child of the Secondary IDE, but
is listed with the correct make/model: Hitachi GD-2000.
Also, there's never a "noide" in the registry.

What is needed to access both the DVD-ROM and the Quantum
HDD from win98? and is it even possible for win98 to
support a HDD (slave) and a DVD-ROM (master) on the
Secondary IDE?

One other idea is using a longer IDE ribbon cable: how
about a long cable that goes from the motherboard connector
to the DVD-ROM (slave) attached with the middle connector,
then reversing back to the center of the cabinet and
attaching the end connector to the HDD (master) ?

Suggestion:

Set your boot drive as master, set the quantum as slave. Remove the end connector from the boot drive and put it on the quantum, then put the middle connector on your boot drive. Run your dvd as master alone on the secondary.

FYI
Windows 98 always assigns hard drives letters before it assigns drive letters to the cd rom drives.

It sounds like the quantum is old (which should be correct since they were bought out by maxtor awhile ago) and you are having a speed problem between the quantum and the dvd on the same channel. You may lose performance if you put it on the primary with the boot drive. You could just buy a new hard drive and ghost the quantum, buy a 3.5" to 5.25 adapter kit to mount a new 3.5 harddrive...
