75gxp && intel 815 chipset

[arne]

Hi

I've replaced my mobo with a D815EEA2/D815EPEA2 PIII 1gig (815 chipset).
I have a 75gxp (ibm) harddisk (46 gig). My bios only recognizes the famous
32 gig (32 gig clip NOT enabled).
If I read correctly, the bios (the latest installed) should recognizes big
harddisk.
Is this a known problem?


thx
Arne

I should have said also:
-before the upgrade the HD was in a AMD k6-2 mobo, with ez-bios on it.
-at that time, i created 1 partition that covered every space above 32 gig
-now ez-bios is removed (I don't know if I can get it back without
formatting the drive?)
-i can read every partition on the disk, except the one above 32 gig
-partitionmagic can see the partition (and tell me how much space is free)
-my bios says "maximum size: 32 gig"

Nope, the 32GB limit has nothing to do with the chipset.

In fact one of my systems has that chipset and no 32GB problem.

Most likely you used some form of 32GB clip on the hard drive
in the previous system and thats still there now, so the drive
is still reporting its size as 32GB in the new system, as you
have told the drive to do. Just remove that. Its either a jumper
on the drive or the drive has been short stroked by software.

Hitachi's Feature Tool can get the drive to report its full size again.

Just reverse what you did to tell the drive to claim its only 32GB.

Yes.

Which clipped the drive to 32GB.

-at that time, i created 1 partition that covered every space above 32 gig

-now ez-bios is removed

So the drive now registers as 32GB.

Right.

-partitionmagic can see the partition (and tell me how much space is free)

Right.

Use HGST's Feature Tool to set the drive back to maximum capacity.

that did the trick indeed. I never realised there was some intelligence in
the harddisk firmware/bios that can cheat it's parameters. I allways
thought it was either by jumpers, or by some ez-bios stuff

thx all

Has been there for a long-long time.
And it doesn't cheat, the settings are real.

or by some ez-bios stuff.

As is the case here. The bios overlay has to set the drive per-
manently to a lower setting to get it to pass the bios detection.
The overlay then sets the drive back to full capacity for the
duration of powered-on or the next hard reset.

indeed, but one could suspect that if you delete the ez-bios, the
removal-program should reset the settings on the drive too... could have
safed me 2 days

It should indeed.
