Reset # heads/cylinder on former RAID HDD


i just got an HDD formerly part of a raid 0 array (3drives array)

the number of head and cylinder when i was trying to creat a new partition with fdisk was wrong.

i reset them to the original number but i still can't mount the partition i created.
so obviously something is still wrong with that.

cqn someone tell me how to reset those informations on the HDD?

thanks

I could be mistaken about how to do this, but I'll give it a try.

Set the cylinders, heads, and sectors in the BIOS. From that information, the BIOS can determine the size of the drive. If the drive is large (greater than 40 Gig), in the same BIOS screen that allows you to edit cyls, heads, etc., tab to the right and change NORMAL to LBA. Save changes and exit BIOS.

Using fdisk (or cfdisk), partition the dive, write the changes and exit. Then re-boot.

The drive parameters that were loaded when you first booted will ocnflict with the new parameters set by fdisk. Re-booting will load the new parameters.

My terminology may be incorrect, but that's how I understand the process.
