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)
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
Have you verified that the chipset supports 4 gig?[/QUOTE] so only 2GB DDR2, 2x2GB freezes and does not start the laptop, max slot1 1GB and slot2 2GB, but only 3GB visible in BIOs and the system only 2GB is used. I915 chipset SL8G7 QG82915PM
