older mobo won't 'see' larger HD

Hi

Old problem.. fitting larger drives to older mobos. I have a couple of PCs
(with 6Gb HDs) that need their HD replacing. I tried a 'small' 40Gb but the
bios did not recognise it. Would fitting a PCI IDE adapter card solve the
problem?

Thanks in advance.. any advice appreciated

Yes, a PCI card is a good idea.

When you write that they're not recognized, do you mean not the capacity
or not at all, no signs whatsoever that you have a drive attached? If no
sign at all of the drive then double-check your drive jumpers.

Flash BIOS is the first and "cheapest" possibility. Cheapest since oteher
two costs you money or performances. Money: buying aditional PCI ATA
controller. Performances: Modyfing drive with Disk Manager software
utility. It will adapt your hard drive for BIOS, but it will limit
transfer to PIO only.

The original 6Gb work fine and will auto detect

PIO only? First I've heard of that. Any reason why?

Do you hear the hard drive spin up when you turn on the power? If the
power cable is connected to the hard drive but it doesn't spin up, could
be a bad hard drive or a bad PSU. If you reconnect the old drive using
the same power cable, does it spin up?

Did you check for loose cables?

Did you check that the colored stripe end of the ribbon cable was on pin
1 of the hard drive and also on pin 1 on the motherboard header for the
IDE port? It really isn't important which way the stripe goes but what
is important is that it is oriented the same way on each end (i.e., you
haven't flipped the cable).

Remove the ribbon cable one end at a time and make sure you didn't bend
any pins.

ATA (IDE) interface that replaced RLL and MFM interfaces had a specifical
distinctivnes, as the market name says, Integrated Drive Electronics.

So, basicly, what ATA controller realy is is nothing else than a bridge
form integrated drives electornic and rest of the system. What system does
when it whants to eg. relocate memory locations on drive to memory is
sending CPU's commands trough PIO to drive. Controller has no particular
and relevant function on this matter, except to physically connect drive
with motherboard.

But now we come to a point where we do not whant our CPU do do that stuff
any longer, and we come to an implementation of a logical circuit that
controls drives operation with resto of sistem without CPU's interference.

Now we come to the drive overlay, that will enable us to see drive in
spite of controllers limitation. Naturaly, if we bypass the controller,
where are we going to get DMA? So, PIO jumps in, and controller is again
used just for physical connection.

Almost forgot. You could try http://www.rom.by/english.html, if you have
Awards BIOS.

Pick any of the user-defined setting in the BIOS...then reboot.

If the BIOS still can't see the drive then, you have a different
problem...more than likely, the jumper is set improperly.

Double check the schematic on the top of the drive for the proper
setting.

Once you get the drive recognized, make sure you change the BIOS
setting back to 'auto'.

But then we progressed to EIDE.

Whan with the EIDE?

Starting with ATA-2, manufacturers started calling their "interfaces"
IDE EIDE, FASTATA, FASTATA-2 i ULTRA ATA.

IDE was used by Conner Peripherals, Compaq and Western Digital starting
back in 1986-1987. It continues to be widely used as the alternate name
for ATA.

EIDE was first used by Western Digital to hype a new line of disk drives
back in 1993 or 1994. These were ATA-2 compatible drives that supported
the new PIO modes 3 and 4 data transfer timings. Western Digital was
trying to establish itself as a major disk drive supplier in those days.
Western Digital continues to use EIDE to describe their products even
though the ATA interface has progressed well beyond the capabilities of
ATA-2. Western Digital is still unshure what EIDE realy is. At first,
EIDE included only PIO modes up to mode 3; then mode 4 was added. When
the new Ultra DMA modes came out, WD of course added support for them to
their newest models, but they kept calling the drives "EIDE"!

FASTATA and FASTATA-2 were used by Seagate and Quantum in marketing
programs that were intended to counter the Western Digital EIDE
marketing hype back in 1993 or 1994. It appears that by 1998 both
Seagate and Quantum had stopped using these alternative names for ATA
products.

In 1999 some companies started to use ULTRA ATA to describe products
that support the ATA/ATAPI-4 Ultra DMA 33 data transfer protocols.

To summ it up, i _hate_ marketing. So i don't realy know if i understud
your comment.
