Cannot Create Partition Error 983

[MorseLady]

I spoke too soon when I said my new XP machine was running well because I now find I cannot create the logical storage partition I wanted. I have done it loads of times on my other machine in ME and XP. I am using Partition Magic 7. I have done error checking/chkdsk, including scan for bad cluster, defrag, closed down NAV auto protect and screensaver and tried both NTFS and FAT32.

Every time I try it reboots and starts up in the partitioning screen then I get a message "Error 983 too many errors found process halted" and I am told to press any key and it returns to Windows. I also had a dialogue box pop up in Partinfo saying "Disk geometry errors were detected on this drive".

This is the message I get on the Partinfo screen

>Info: End C,H,S values were large drive placeholders.
Actual values are:
0 0 80 0 1 1 07 9729 254 63 63 156312387
Error #109: Partition ends after end of disk.
ucEndCylinder (9729) must be less than 9729.

The HDD is 80GB and 512MB DDR memory and 2.2GHZ Intel Pentium 4 and factory installed OEM XP Home 2002 release and the BIOS is Award. I have had the computer 4 weeks.

Is PM7 misreporting because all Windows and other tests show I have a healthy disk and system and the computer is running very well indeed or did the factory do a b***s up? I believe PM7 supports up to 80GB HDD and maybe as mine is 80GB PM7 sees it as too large? The Partition I am trying to create is 5GB Logical NTFS, for storage but I tried FAT32 too.
