    Hello.
    IDE drives can have up to 137GB capacity, but HP might have set a limitation of 100GB. I'll check what I can do with it.

    The 128 GB barrier (or 137GB depending if you count in base 1000 or 1024) has nothing to do with being IDE, it has to do with being an *OLD* IDE controller with the 28bit LBA support (over the more modern 48bit one).

    @NacherasTM

    Not sure how they behave with XP but I think the most recent versions of BIOS extenders like MaxBlast, Ontrack DIsk manager and alike can remove this limitation just like they did with previous barriers of even older controllers.

    Whatever is something I haven't touched in the last 20 years so my memory may fail.

    P.S. Be sure you're using XP SP3 or Win2000 SP4, because older version of XP and Win2K also didn't understand the LBA48 addressing (which was released around 2003 or so)

    I´m using an old HP Pavilion dv1000, and came with a 100gb hdd, now I´m trying to increase the space and installing W XP SP3 the setup detects the drive as 32gb, very strange. It´s a 2004 laptop. The thing is that with an old 2001 gigabyte motherboard I did the same thing and worked like a charm.

    There are many DV1000s with various generations of Pentium M and Core and also with an AMD CPU.

    Indeed is strange that a 2004 PC is not LBA 48 ready, but clearly that seem the case, at least on your model/generation.

    Sadly I have one of them here but I can't check anything because it was damaged beyond repair by the piss of a tiny dog of the ex owner of that machine.

    Probably the best thing you can do is to use a cheap 64/128GB SSD (mSata drive + msata/pata adapter) as a primary drive and put the large HDD in a tray in the dvd slot.

    (look for dvd tray or dvd caddy on amazon, ebay.... they cost even less than 10$, although PATA ones may be harder to source)

    The historic limit is 128/137GB. If your PC refuses to see a 120/128GB disk it's a bug, not a limit.

    BIOS bug, or disk bug?

    Not maybe, that's the ONLY purpose of so called disk overlay SW, that's what I suggested to do first.

    BUT

    Keep in mind it's more a workaround than a solution. It's something that works until it works, but can provide a good amount of headaches if something goes wrong (say a corrupt file on the disk overlay SW, or a partitioning SW that skips it, and messes with the partition table and so on).

    SO

    Even if a more expensive way, I still suggest to go for the 64 or 120GB mSATA + (optional) DVD tray for a larger HDD
