13. Why doesn’t my operating system show the full capacity of my drive?
Few systems built before 1997 support drive capacities greater than 8.4 GB, because the CHS
(Cylinders, Heads, Sectors) method of translation uses ID words 1, 3, and 6 of the Identify Drive
Command. The maximum values for words 1, 3, and 6 are 16,383 cylinders, 16 heads and 63
sectors for a capacity of 8.4 GB. A new extended interrupt 13 function was defined to get beyond
this boundary. By mid-1998, most new systems had introduced this support. Problems with
systems that do not support greater than 8.4 GB can be solved with one of the following options:
•
Obtain a BIOS upgrade from your system vendor that includes Extended Interrupt 13
support.
•
Use IBM Disk Manager 2000 to install your IBM Deskstar.
•
Purchase an IDE controller card with an onboard BIOS that supports Extended Interrupt 13.
14. What capacity limitations should I be aware of when installing my operating system?
Windows 95A supports Extended Interrupt 13. Windows 95 can see drives greater than 8.4 GB,
but uses the FAT16 file system. The drive needs to be partitioned into 2047MB partitions.
Windows 95 SR2 and Windows 98 support Extended Interrupt 13 and offer an option to use a
FAT32 File System (Large Mode) and partitions larger than 2047MB.
Novell Netware v3.12 does not support drives larger than 8.4 GB. If a drive larger than 8.4GB is
attached, Netware will see only 8.4GB of the drive’s capacity. Novell (IWSP6.exe) has provided
more recent drivers for this release of Netware.
Windows NT 4.0 Service Pack 1 and 2 do not support IDE drives larger than 8.4 GB. Microsoft
has added greater than 8.4 GB support with NT Service Pack 3, 4, 5, or 6.
15. Why did my drive letter assignments change after installing my IBM Deskstar?
Drive letters are assigned by the operating system, not by the BIOS, hard drive, or IBM Disk
Manager 2000 Easy Installation Software. The operating system assigns drive letters with each
boot. The floppy drives are assigned first, then the hard drives, starting with the Primary Master
ATA/IDE hard disk drive, followed by remaining devices in the system.
16. When do I configure my drive for 15 heads rather than 16 heads?
The default configuration of the IBM Deskstar is 16 heads. Your system may require the drive to
be jumpered to 15 heads. Some computer systems translate a drive greater than 4 GB by
multiplying the head count by 16. The result (16 x 16 = 256) is interpreted as 0 heads with 0
capacity and is an illegal head count. Jumpering the drive to 15 heads (16 x 15 = 240) produces
a legal translation. The translated cylinder count varies to achieve the drive’s full capacity.
17. How do I create a Windows 95 or 98 startup diskette?

Windows 95 or 98 startup diskette.
