Handling precautions/Electrostatic discharge protection
•Disc drives are fragile. Do not drop or jar the drive. Handle the drive only by the edges or frame.
•Drive electronics are sensitive to static electricity. Keep the drive in its antistatic container until you are ready to install it. Wear a wrist strap and cable connected to ground. Discharge static from all items near or that will contact the drive. Never use an ohmmeter on any circuit boards.
•Turn off the power to the host system during installation (not necessary if you are using a
•Always use
•Use caution when troubleshooting a unit that has voltages present.
•Do not disassemble the drive; doing so voids the warranty.
•Return the entire drive for depot service if any part is defective.
•Do not apply pressure or attach labels to circuit board or drive top.

What you need
•Screwdriver and four M3 x .5 metric drive mounting screws
•
•Backplane host system or enclosure that supports SCA
Note. To operate at LVD transfer rates, you need a backplane that sup- ports LVD devices.

This drive can operate in
Note. To operate at Ultra2 rates or faster in LVD mode, all devices on the same bus must be running in LVD mode. If you add any SE device to the bus, all devices on that bus operate in SE mode.
Caution. Do not mix LVD drives on the same bus with high voltage differ- ential (HVD)
Installation instructions
SavvioTM drives have an
1. Mount the drive in the carrier or tray
LC drives are designed to be attached to a carrier or tray and inserted into the host system without I/O or power cables.
Savvio drives provide 4 mounting holes on the bottom of the drive, 2 mount- ing holes on each side of the drive, and 2 mounting holes on the end of the
drive. Refer to the host system’s documentation to determine which holes to use to mount the drive in the carrier or tray.
Use M3 x .5 metric screws. Do not
2. Format the drive
The drive has been low level formatted at the factory. You do not need to perform another low level format on this drive unless you decide to perform certain diagnostics through the host adapter. If you do decide to perform a low level format, do not abort the format as this is likely to make the drive inoperable. A low level format, with verify turned on, will typically take two hours.
Protect against power failure or other power interruptions during the format.
a.Turn on DC power to the host system.
b.Boot the system from a system floppy, CD, or from a previously installed hard disc drive if there is one.
c.Format the drive.
Caution. Formatting a drive erases all user data. Be sure that you under- stand this principle before formatting any hard disc drive. It is not necessary to format a drive that previously has been used to store data, unless your intention is to erase all user data. Seagate® is not responsible for lost user data.
Savvio disc drives are designed to operate with a variety of operating sys- tems. Please refer to your system or host enclosure manual for information about formatting and setting up the drive.
Troubleshooting
•Drive does not spin up. Ensure that the host system is supplying power to the drive’s SCA
•Computer does not seem to recognize the drive. Verify that the drive is enabled by the SCSI host adapter setup utility.
