[comp.sys.ibm.pc] IDE controllers

Hi...I just decided to replace my st506 drive with an IDE drive.  I swapped
out the controller and installed the disk.  Now comes the problem.
My BIOS setup program doesn't have this one listed, so I need to input
the parameters myself.  The BIOS (Phoenix) has the following fields:Cyl, Hd, 
Pre, LZ, and Sec.  
My drive came with the following data sheet:
Model: ST1144AT
ROM ver: 5.0
RAM ver: 5.d
Drive Geometry
Cyls: 1021  Heads:7  Sectors/Track 44 36 30   Bytes/Sector 512
Ok, cyl and hd are obvious, but for sectors... which number should it be?
I used 30, and everything is fine, but then it formats out to just over 
100 meg, and I was told this would format to 120 or so.  When I tried
44 or 36 I get a "Hard disk error" when I try to boot.

Can anyone tell me how to get the extra space?  
Please respond via email
