Lost HDD space after XP Partitioning

Microsoft / Windows xp pro
July 6, 2009 at 10:08:09
Specs: Windows XP Pro
I just built a new PC and when installing XP I elected to create a 140G partition on my 500G drive.
Now I have a 128G drive and can not see the remainder of the drive.
No matter what I've tried, I can't get it back. I wish I had my old W98 disks because I know FDISK will kill the partitions and let me start over.

Anyone else know another way?

Tom

Are you looking at My Computer or Disk Management?

Both.

It also appears as a 131G if I run the XP install again.
The installer offers the option to delete a partition. I tried that and the result is the same. The setup can only see 131G.

so in disk management you see no free space?
disk management says its only 131gig whereas the bios is reporting 500gig?

use the xp install to delete the partition

Correct, the disk manager does not see any free space.

And as I stated, I tried to use the XP install to delete the partition. It showed that it had indeed deleted it, but then reported the same 131G as available for a new partition.
I even rebooted after deleting the partition but the result was the same.

The bios does report 500G.
(SATA drive BTW)

xp required sp2 to see drives larger than 128gig. If you are using xp to setup the drive this could be the issue.

solution would be to slipstream your xp sp1 disk to create a xp sp2 disk. Google slip streaming xp for the how to.

Or work with what you have and then sp3 xp then you should see the remaining disk space as free space so you can partition it.

Actually, WinXP SP1 is also 48 bit LBA compliant, which means it can work with drives larger than 127GB.

Tommy

Watch the POST screens at start up to verify that all your drives are properly identified by both model and the FULL rated capacity.

Check the above before trying anything else.

If the hard drive shows in the POST screens as 500GB then the issue is your WinXP installation CD may not have any service packs included.

wanderer,
Thanks for the slipstream info.
I have complied a SP2 disk, but have not tested it yet.

A friend gave me a copy of Windows 7 eval and I loaded it.
It recognized 480ish Gigs right away and partitioned it with no problem.
I went ahead and installed 7 and will play with it for a while to see if I like it.

If not, I'll be back to XP ;)
Of course, now that the partition is corrected (at least somewhat) I won't know if the slipstream version made a difference. And no, I'm not gonna try to make it happen again for the sake of science! ;)

Thanks all,
TG
