Seagate ST31270A Dual-drive emulation installation, Model Setup Mbytes Cyl Heads Sectors, 024

Medalist 1270 Installation Guide, July 1995 19

If a user-defined drive type is not offered, select a drive type that approximates, but does not exceed, the CMOS (Setup) Mbytes capacity in the translation geometry table above.

Note. The drive does not use write precomp and landing zone. If these parameters are listed, make their values zero.

If you upgrade your system at a later date to achieve the drive’s full capacity, you must repartition and reformat the disc. Be sure to back up your data first.

5.When you have completed setting the translation geometry for your drive, save the values and exit System Setup. Reboot your computer. Refer to your user’s guide for assistance.

6.Partition and format the drive.

Dual-drive emulation installation

Dual-drive emulation makes the drive two logical drives for the computer. Each logical drive is assigned a drive type in System Setup and must be partitioned and formatted. Use the translation geometry values shown in the table below. They are the maxi- mum values your BIOS supports. A second, physical drive cannot be installed on the same port when dual-drive emulation is used. To configure your computer for dual-drive emulation:

1.Follow steps 1 through 3 in the “Standard setup” section on page 18.

2.Use the translation geometry in the table for both drive types.

		Dual-drive emulation			CMOS

Model					(Setup)
	Mbytes	Cyl	Heads	Sectors	Mbytes
				per track
ST31270A	527.4	1,024	16	63	504

3.Save the values and exit System Setup.

4.Partition and format both drives.
