Connecting cables and mounting the drive

1.Connect the interface cable to the drive. Make sure that pin 1 on the interface cable (colored stripe) is attached to pin 1 on the drive and pin 1 on the host adapter.

2.Partially insert the drive into the drive bay. Select an unused power connector from the power supply and connect it to the drive. If there are no unused power connections on the power supply, you can purchase a “Y” cable adapter from your dealer.

3.Secure the drive with four 6-32 x 0.25 screws. CAUTION: If you use screws longer than 0.25 inch when mounting the drive, you may damage the drive’s circuit board. The maximum insertion depth for the bottom mounting holes is 0.25 inch; the maximum insertion

depth for the side holes is 0.125 inch.

About Disk Manager Software

This Seagate drive is shipped with free Disk Manager software. This software partitions and formats the drive and allows older computers to access the drive’s full capacity.

Running Disk Manager

1.Insert a bootable DOS diskette in your A drive and restart your computer. During the start-up process, enter your computer’s System Setup program (sometimes called BIOS or CMOS setup). This is usually done by pressing a special key, such as [DELETE], [ESC], or [F1], during startup. See your computer manual for system-specific instructions.

2.Within the System Setup program, make sure that a drive type is listed for each ATA hard drive in your computer. Some newer computers can automatically determine drive-type characteristics, using the Auto drive-type setting. If your computer does not provide this option, you must manually enter the number of cylinders, heads, and sectors per track for your new drive, as shown in the table below.

Model	Heads	Cylinders	Sectors	Capacity*

ST31621A	16	3146	63	1623 Mbytes

*1 Mbyte = 1,000,000 bytes

3.Save the drive-type settings and exit the system setup program. You will have to reboot your computer for the changes to take effect.

4.Insert your Disk Manager diskette. At the DOS prompt, type A:\DM. Press [ENTER] to run Disk Manager

5.Follow the instructions on your computer screen. From the main menu, select (E)asy Disk Installation. Then press [ENTER].

6.At this point, Disk Manager lists all the hard drives that it can recognize. You should see your new Seagate drive and your old hard drive (if any). If Disk Manager recognizes all your drives, select the new drive you wish to install and press [ENTER]. Disk Manager will format and partition your new drive.

If Disk Manager does not recognize a hard drive, exit Disk Manager and turn off your computer. Check all cables, jumpers and BIOS settings. Then run Disk Manager again.

7.Follow the instructions on the Disk Manager post-installation screens. You're done!

NOTES:

1)If your computer does not require software support for large hard drives, Disk Manager will optimize your system BIOS settings, then quickly partition and format your new hard disc.

2)If Disk Manager has installed software to help your computer access a large hard drive, you should see a blue Disk Manager banner each time you boot your computer. In this case, if you need to boot from a diskette instead of from your hard drive, see the Disk Manager online manual for instructions.

3)To view the Disk Manager online manual, insert the Disk Manager diskette and type A:\DM /H. Then press [ENTER]. You can also view the online manual from within Disk Manager by selecting (V)iew/Print Online Manual in the main menu.
