Configuring the computer
Configure your computer for the drive as follows:
1. Turnthe computer on andfollow the manufacturer’s instructi-
ions for running the CMOS Setup routine.
2. When CMOS Setup starts, first select a drive type that
matches your drive’s translation geometry:
IfnoneofthestandarddrivetypesofferedbytheSetuproutine
match the translation geometry shown in the following table,
select the
user-defined or custom drive type to enter your
drive’s translation geometry.

3. A jumper must be installed over pins 33 and 34 of jumper
block J8.
ST5660A Installation Guide, Rev. B 9

If your Setup routine does not offer a user-defined drive type,
select a standard drive type with a capacity that most closely
approximates, but does not exceed, your drive’s CMOS ca-
pacity (shown in the table’s last column). If you do not know
what drive types your Setup routine supports, download the
FindType utilityfrom SeaBOARD (see page 18) to assist you
in choosing an appropriate drive type.
4. The drive does not use the write precomp and landing zone
parameters; entered valuesare ignored by thedrive.For both
parameters, enter as a value the number of cylinders plus 1.
5. SaveintoCMOSmemorythechangesyoumadeandexitfrom
the CMOS Setup routine.
Low-level formatting
AT drives are low-level formatted at the factory to 512 bytes per
sector. You do not need to low-level format AT drives.
Partitioning
You must partition a drive into one or more logical drives before
you can use it. If you are using DOS Version 3.3 or earlier, disc
partitions are limitedto approximately 32 Mbytes. Beginning with
DOS Version 4.0, you can put the entire drive on one partition.
Partitioning is described in your DOS manual.
Caution. Partitioningor formatting adrive atany level erases all
dataonit.Before yourepartition or reformatyourdrive,
saveallexistingfilestobackupfiles.Seagateassumes
no liability if you erase your data.
10 ST5660A Installation Guide, Rev. B

High-level formatting
High-level formatting verifies the information written by the low-
levelformatandbuildsthefileallocationtable(FAT)usedbyDOS
to access files on the drive. Consult your MS-DOS manual to
learn howtousetheDOSFORMATutilitytohigh-levelformatthe
drive.
In Unix, high-level formatting creates the i-node used for file
access information. Drive formatting and partitioning are both
performedby a singleoperating system utility.Refer toyour Unix
operating system documentation for instructions.
Troubleshooting
In the event of problems, you should perform the following basic
checks, which can resolve common installation difficulties.
Warning. Always turn your computer off before changing jump-
ers or unplugging cables and cards.
•Verify compatibility. Verify that the host adapter and the
drive are appropriately matched to each other and to your
computer. Refer to relevant documentation for details.
•Verify equipment configuration. Using the instructions in
the drive and host adapter installation guides, make sure that
all appropriate jumpers are installed, or removed, as needed.
•Check the power supply specifications. If new devices are
installed, your computer’s power supply may not support new
total powerrequirements. When in doubt,consult your dealer.
•Check all cards. Verify that all cards are seated in their slots
on the motherboard and are secured with mounting screws.
ST5660A Installation Guide, Rev. B 11

•Verify the CMOS drive type setting. The drive type setting
stored in CMOS memory using CMOS Setup must approxi-
mate,butnotexceed,thephysicalspecificationsofyourdrive.
•Check all cables. Make sure all ribbon cables are securely
connected. Verify that they are not crimped or damaged, and
ifindoubt,substitutecablesthatareneworknowntobegood.
Verify for each cable that cable connector pin 1 aligns with
equipmentconnectorpin1.Pin1isoftendenotedbyacolored
stripe on one edge of the ribbon cable.
Caution. Do not reverse-plug connectors. This can damage
the computer and the drive.
Note. A floppy diskette cable contains a split and twisted
section and cannot be used with a hard drive.
•Check for viruses.
Before you use someone else’s diskette
in your system for the first time, scan the diskette for viruses.
If the preceding basic checks have been done and the problem
still is not solved, follow these guidelines for troubleshooting:
The system does not recognize the presence of the drive.
•Check all cables.
•Make sure the power supply is adequate to system needs.
•Reboot the computer and make sure the drive motor runs. (If
your drive is very quiet, it may be difficult to hear it come to
operating rotational speed.) If the drive does not appear to be
running, check all drive cables.
•Verify the CMOS Setup drive type values.
•Tryawarmboot(arebootwithoutturningoffcomputerpower).
To do this, press CTRL, ALT, and DELETE at the same time.
12 ST5660A Installation Guide, Rev. B

If a warm boot causes a previously unrecognized drive to
become recognized, there may be a timing problem in which
the drive fails to become ready before the computer’s power-
on self-test is complete.
One possible solution is to slow your computer’s processor
speed during startup. If your computer has a turboswitch, set
it to slow speed before turning the computer on. If there is no
turbo switch, you may be able to use keyboard commands to
slow the processor speed; see your computer manual for
details. After the computer is up and running, return the
processor to the fast speed. Another solution is to warm-boot
your computer after every power-on.
•Check for I/O address conflicts. To isolate the conflict, first
verify that the drive andhost adapterare compatiblewithyour
computer by removingallperipheraladaptercards,exceptthe
video card; then reinstall the drive and host adapter card. If
this is successful, reinstall the peripheral cards one at a time
until the conflict reoccurs.
After you have isolated the source of the address conflicts,
youcanresolvetheconflictbychangingtheI/Oaddressofthe
peripheral that appears to cause the conflict.
The dealer partitioned and high-level formatted the drive for
you in the store.Later, you installed the drive and it does not
work at all.
•Reboot the computer and make sure the drive spins up.
•Check all cables.
•Make sure the power supply is adequate to system needs.
ST5660A Installation Guide, Rev. B 13

•Use the same version of DOS within all partitions. Make sure
thattheDOSversionthedealerusedtopartitionandhigh-level
format the drive is the same as theversion you have installed
on your computer. If it isn’t, see your dealer.
•Verify the CMOS drive type setup value. You must install the
drive using the same drive type or translation geometry that
was set before initial partitioningby your computer dealer.
•Check for I/O address conflicts between peripheral cards.
•Check for viruses.
The screen goes blank when you power up the system.
•Make sure the monitor is plugged in and turned on.
•Check all cards. Make sure the video card is seated in its slot
and secured with a mounting screw.
•Check all cables. Make sure the video-card cables are se-
curely attached.
•While the computer is powered down, remove the drive host
adapter. If the screen turns on after you reboot, the host
adapter may be incompatible or defective. If so, see your
dealer.
The system hangs in FDISK or fails to create or save the
partition record.
•Check all cables.
•The DOS utilities diskette may be corrupted. Try your backup
DOS diskette.
•Make the partitions smaller.
14 ST5660A Installation Guide, Rev. B

•Use another drive type or translation geometry. Sometimes
the computer’s BIOS does not accept a particular translation
geometry value for writing into the CMOS Setup memory.
•Change the interrupt jumper setting on the host adapter.
•Check for media defects at the beginning of the drive. Use a
third-party surface scan utility.
TheFDISKerrormessage,“NoFixedDiskPresent,”appears.
•Check all cables.
•Make sure the power supply is adequate to system needs.
•Reboot the computer and make sure the drive spins up.
•Verify the CMOS setup drive-type setting.
•Check for I/O address conflicts.
DOS messages, “Disk Boot Failure,” “Non-SystemDisk,” or
“No ROM Basic - SYSTEM HALTED,” appear.
•Check all cables.
•Use the same version of DOS throughout all partitions.
•Reinstall the DOS system files using the DOS SYS utility.
•Use FDISK to verify that the primary partition is active.
•Check for viruses.
System error message, “Drive not Ready,” appears.
•Check allcables.Foreachdriveribbon cable,verifythatcable
pin1isalignedwithdriveorhostpin1.Pin1isusuallydenoted
by a stripe on the side of the ribbon cable.
•Make sure the power supply is adequate to system needs.
•Reboot the computer and make sure the drive spins up.
ST5660A Installation Guide, Rev. B 15

During the DOS high-level format, the drive does not format
to full capacity.
•Verify yourcomputer’sCMOS drivetypesetting.Oneofthese
problems may have occurred: 1) CMOSSetup may be set for
an incorrect drive type or translation geometry; 2) you may
have entered a parameter value that exceeded the physical
capacity of the drive; or3) you selected a CMOS geometry or
drive type that does not take full advantage of the drive’s
capacity.
If any of these cases is true, follow the instructionson page 7
forconfiguringthecomputer.IfyouresettheCMOSdrivetype,
partition and high-level format the drive again. Note thatDOS
does not allow more than 1,024 cylinders.
•If you partitioned the drive into individual logical drives, you
may need to make the partitions smallerso that the computer
can use all of the drive’s capacity.
