enable 48-bit LBA XP Pro SP1

[Krishnou]

Hi all,

I have a problem enabling 48 bit LBA under XP Pro SP1.

I have a 160G disk with two partitions (40G for C: and 120 for D,
this is the only disk on the machine.

I only had Windows WP Pro base install disc which does not support
disks larger than 137G. I installed it on the C: drive and of course
only the 40G on C and 88G on D: are recognized by the system, the rest
of the D: drive space is marked as used although there is no data on
this partition.

I then installed SP1 for XP and followed the instructions of this
article to enable 48 bit LBA hoping that would solve my problem
http://support.microsoft.com/default.aspx?scid=kb;en-us;303013

I have the right version of atapi.sys and my bios and motherboard both
handle LBA but XP still doesn't recognize the full size of the disk.

Tried to use partition magic 8 to reformat the 120G partiton but it
failed at reboot with error 626 "trying to format disc not recognized
at boot" or something similar.

I also tried to splitstream XP + SP1 but did not manage to make the cd
bootable.

Can someone please advise on other possible solutions ?

Many thanks
Chris

Hi again,

Problem solved, I used diskmgmt to reformat partition D:
I have the full size available now
