I am trying to install Red Hat 7.1 and my HDD model has 6139 cylinders. Disk Druid shows only 767. It is also way off on the amount of heads. I have 16 and it shows 128. The sectors is the only one of the three that is correct in the reported geometry. Also, it reflects the correct drive MB size total of 3020, or say 3GB roughly. It's a Western Digital HD. When I first power up, my computer BIOS shows the correct settings. It's only at the DRUID where there is a problem. What can I do to correct this so I can move on with the installation?

Use fdisk in expert mode, reset the disk geometry values to your CHS values, then create the partitions.
