750gb HDD only shows 133gb in XP pro

I've recently done a re-install of XP Pro on a seagate 750GB Hdd. Windows however only shows 133gb. I've gone into administrative tools-storage & can see the extra space, but can't merge the 2 partitions together. Any solutions? Many thanks in advance, Gary S.

XP Pro SP0 only recognizes that much disk if I recall correctly. So you need to get an XP disk with SP2 as part of it.  ... Thinkpads_User

It's an addressing issue with the initial version of XP:

Upgrade your new install to at least SP1, then use a program like GParted (it's part of the SysRescue CD) to grow the partition if XP's installer actually made the initial partition 133GB.

I am having this issue with sp1a, sp-2 & sp-3 installed. My BIOS shows the 750GB HDD.

Also, using NTFS in primary partition (133GB [shown}).
Is it a SATA drive?  Could well be. And if that is the case, Windows XP will not install natively.

See if you have a setting in your BIOS to change AHCI to Compatability Mode. If you can do that, delete any and all partitions on the 750Gb drive and try again.

Also, the largest workstation drive I have used for any operating system install is 500Gb. XP SP3 will work with drives bigger than 133 Gb, but I don't know if any XP install will go as high as 750Gb. You may have to try a smaller partition.

As [Thinkpads_User] notes, you'll need an installable version of Windows XP with SP2 or SP3 already built in.
Gary, what about my post??

Lead me in the right direction & proper path to discovery. I learned from this on the way. Thank you,

BTW, I eventually used Partition Commander 10 to merge the unallocated space to the existing primary partition, which gave Windows the full view to the HDD.
thanks for feedback
