2 Verify installation
Once you have installed the drive hardware, check that drivers have been
installed correctly and you have the correct version of backup software, and
verify that the tape drive is functioning properly before you store your valuable
data.
1. Switch on the server.
2. The tape drive will run its hardware self-test, which takes about 5 seconds.
If self-test passes, the green Ready LED flashes and then shows steady
green. If the test fails, the Drive and Tape LEDs flash, while the Ready and
Clean LEDs are off. This continues until the drive is reset. See
"Understanding LED sequences" on page 27 for more information about
front panel LEDs.
●If you installed drivers before connecting the tape drive (Windows
only)
The tape drive should be detected automatically and the correct drivers
used.
●Installing drivers after connecting the tape drive (Windows only)
If you have not already installed drivers, install the driver according to the
supplied documentation
in the driver's folder.
●Installing drivers (other operating systems)
Drivers are included with the operating system and should be loaded
automatically.
NOTE:
Certain backup applications require you to use their own Tape driver.
3. Verify that the tape drive installation was successful.
4. For all operating systems ensure that you have downloaded any upgrades
necessary for your backup application.

4 Cautions concerning backup
In this chapter:
●"Ejecting the data cartridge after backup" on page 15
●"Data compression rate" on page 15
●"Backup performance/capacity" on page 16
●"Points to note during system configuration" on page 16
4.1 Ejecting the data cartridge after backup
●Do not leave the data cartridge in this product.
Doing so makes the data cartridge wear faster, because the longer it is used,
the faster it wears. The tape recording surface of the data cartridge is
exposed when inserted in this product and if it is left in this state for a long
time it will easily be affected by suspended particles of dust. Insert the data
cartridge just before the backup operation, and remove it immediately after
the operation.
●Do not turn off the power with the data cartridge inserted.
If the power is turned off with the data cartridge inserted, it takes a while
before this product can be used after the next power-on.
4.2 Data compression rate
This product has a data compression function included in the hardware.
Although the data compression rate is approximately 200%, it varies depending
on the data content.
Data that has already been compressed by software is not effected by this
product.
Some backup software has a data compression function prior to transfer,
however, do not compress data by software if the hardware compression
function is on.

16 LTO-5 Half-Height SAS Tape Drives
Backup performance/capacity
4.3 Backup performance/capacity
The backup performance and backup capacity that can be used in one data
cartridge varies depending upon the following factors:
●The conditions (attrition, dust, etc.) of the recording surface of the data
cartridge to be used
●The dust and dirt condition of the product's magnetic head
●The data compression rate
●The workload on the server
4.4 Points to note during system configuration
When repeatedly using a single data cartridge, all the data can be lost if the
backup fails. Also, if a backup data cartridge becomes damaged, the data
cannot be recovered.
Damage in the event of a failure can be minimized if two or more data cartridges
are used for backup operation. For example, use different data cartridges for
each day of the week.

5 Use the correct media
In this chapter:
●"Cartridges" on page 17
●"Cartridge life" on page 18
●"Write protecting cartridges" on page 19
●"WORM data cartridges" on page 20
●"LTO-5 tape drives and encryption" on page 20
●"Cleaning the tape drive" on page 23
●"Handling cartridges" on page 23
●"Storage environment" on page 24
5.1 Cartridges
5.1.1 Cleaning cartridges
Use the universal cleaning cartridge. It may be used for up to 50 cleans.
5.1.2 Data cartridges
LTO–5 tape drives use LTO Ultrium 5 tape cartridges. These are single-reel
cartridges that match your drive's format and are optimized for high capacity,
throughput and reliability. Compatible media can be recognized by the Ultrium
logo, which is the same as the logo on the front of your drive. Do not use other
format cartridges in your tape drive and do not use LTO Ultrium 5 cartridges in
other format tape drives.
To achieve best performance we recommend using only “Fujitsu — Preferred
Quality” LTO Media cartridges.
For optimum performance always use LTO Ultrium 5 data cartridges because
they match the specification of your tape drive. A lower specification will have a
lower transfer speed and may not support write activities; a higher specification
will not support read or write.

18 LTO-5 Half-Height SAS Tape Drives
Cartridge life
The drive supports the following LTO data cartridges:
5.2 Cartridge life
To avoid a backup failure due to worn media, replace the media (data cartridge)
before either of the following occur:
●After one year of use
●After being used 1000 times
The lifespan of media varies depending on the environment (temperature,
humidity, dust, etc.) and operating conditions of this product.
IIMPORTANT:
The data cartridge is a replaceable part. Worn media can cause
problems such as magnetic tape surface damage, dirty magnetic head,
many media errors, and so on. See also "Problems with cartridges" on
page 32.

Write protecting cartridges
5.3 Write protecting cartridges
WWARNING!
Always remove the cartridge from the tape drive before you change the
write protection.
If you want to protect the data on a cartridge from being altered or overwritten,
you can write protect the cartridge.
●To write protect a cartridge, push the switch to the right to prevent any data
recording on the cartridge. Note the padlock on the tab that indicates that the
cartridge is protected.
●To write enable a cartridge, push the switch to the left to allow data recording
on the cartridge. Figure 5 on page 19 illustrates the location of the write-
protect tab.
Figure 5: Write protecting a cartridge

WORM data cartridges
VCAUTION:
Write-protection will not protect your cartridges against magnets. Write-
protection will not prevent a cartridge being erased by bulk-erasure or
degaussing. Do not bulk erase LTO format cartridges. This will destroy
pre-recorded servo information and make the cartridge unusable.
5.4 WORM data cartridges
The LTO–5 tape drive includes support for both re-writable and Write-Once,
Read-Many, WORM, data cartridges. WORM cartridges provide an enhanced
level of data security against accidental or malicious alteration of data on the
tape cartridge. The WORM data cartridge can be appended to maximize the full
capacity of the tape cartridge, but the user will be unable to erase or overwrite
data on the cartridge. Any attempt to modify a WORM cartridge to enable
writing over existing data will result in the media becoming permanently write
protected. It should still be readable in a WORM drive, depending upon the
severity of the tampering, but no further appended backups will be possible.
WORM data cartridges are clearly identified by their distinctive, two-tone
cartridge color. They can only be used with LTO tape drives that support the
WORM feature.
To check whether your backup or archive software application supports WORM
cartridges, refer to the software manual.
5.5 LTO-5 tape drives and encryption
The LTO–5 tape drive includes hardware capable of performing data encryption
at full speed while writing data, and decrypting when reading.
Encryption is the process of changing data into a form that cannot be read until
it is deciphered, protecting the data from unauthorized access and use. LTO–5
tape drives use the strongest version of the industry-standard AES encrypting
algorithm to protect your data.
To make use of this feature you need:
●A backup application that supports hardware encryption
●LTO Ultrium 5 media (recommended) or LTO Ultrium 4 media; no encryption
will be performed when writing earlier generations of tape
