My 80gb IDE hard disk recently failed and I have replaced it with a 160gb IDE hard disk. The BIOS correctly identifies the size of the disk, but Windows (XP Home SP2) thinks that the disk only has a capacity of 127gb. Is there a registry setting that I have to change to bring Windows into line or is it something else?
I believe that this is a Microsoft imposed limitation of the FAT32 file system. If you don't mind starting again you could format the drive as NTFS during setup then the full drive will be used. Another alternative is to convert the drive to NTFS and use something like Partition Magic to extend the active partition to fill the drive. Yet another possibilty is to go into Drive Management and create a new partition in the unallocated space and use this as a second drive.
