If you had booted with the XP cd, it would have set up the entire drive as either one partition or divided it according to your wishes using NTFS....as it stands the normal 'fdisk' used has a limit of 127GB for the drive size. You can try going into DOS with a W98 bootdisk and then using FDISK to add an extended partition and logical drive for the rest of the space.
I have a dell 8400 with pentium4,2.8gig, 1gig of ram,80 gig hard drive ,windows xp pro. I just installed a 250 gig hard drive as a backup, after formatting and partitioning i went to the disk management and it shows up as 127gig. Did i set the wrong auto in bios? My bios showed master and slave for sata drives , nothing chosen, then master and slave again with my old drive set to on, i set the slave to auto then exited and saved. I formatted with the seagate disc wizard and then rebooted. Can anyone suggest what I might have done wrong and how to fix it.
Thanks for any info
