Frequently Asked Questions - AITI390 SONY

How to clean the AITi390 drive?

Use a SDX3X-CL cleaning cartridge specially designed for this model. Insert it into the drive; cleaning starts automatically and lasts from a few seconds to one minute. The cartridge is ejected automatically at the end. Do not reuse a used cleaning cartridge.

Which cartridges are compatible with the AITi390?

The drive supports writing and reading on AIT-3 and AIT-3 Ex cartridges, and read-only on AIT-1 and AIT-2 cartridges. Only use cartridges bearing the AIT logo. 8 mm video cassettes are not compatible.

How to set the SCSI ID of the drive?

The SCSI ID is configured using jumpers located on the drive. SCSI ID pins 0 to 3 allow selecting an ID from 0 to 15. Refer to the jumper table in the manual. Ensure the ID does not conflict with other devices.

What does the CLEANING REQUEST indicator mean?

The CLEANING REQUEST LED lights up after approximately 100 hours of use to indicate that cleaning is needed. Use a cleaning cartridge immediately to maintain drive performance. This LED can be enabled or disabled via DIP switch 6.

Can I use AIT-1 cartridges in the AITi390?

Yes, the AITi390 can read AIT-1 cartridges, but it cannot write to them. For writing, use AIT-3 or AIT-3 Ex cartridges.

How to activate Disaster Recovery (DR) mode?

DR mode is activated via DIP switch 1 (ON position). In DR mode, insert a write-protected cartridge: the drive enters DR standby after 15 seconds, all LEDs blink. A restart then makes it appear as a CD-ROM device. Refer to your backup software manual for details.

What to do if a cartridge gets stuck?

Perform emergency extraction: remove the drive from the enclosure, open the top cover, then turn the loading motor shaft clockwise with a precision screwdriver to return the mechanism to its initial position. Remove the slack of the tape by turning the gear counterclockwise. Continue turning until the cartridge is ejected. Send the drive to Sony for repair after this procedure.

Is data compression automatic?

Yes, compression is enabled by default (DIP switch 7 ON). It can be disabled via DIP 8. The typical compression ratio is 2.6:1, but it varies depending on the data type.

What is the maximum capacity of the AITi390?

In native capacity, the drive offers 150 GB on an SDX3X-150C cartridge. With compression (2.6:1 ratio), capacity reaches 390 GB. Actual capacity depends on data type.

How to install the AITi390 in a 3.5-inch enclosure?

The drive is shipped in 5.25-inch format with side rails. To convert to 3.5-inch format, remove the two screws from each rail, then remove the rails. Then mount the drive directly in the 3.5-inch bay using appropriate screws.

Precautions

Installation

Avoid placing the drive in a location subject to:

– high humidity

– high temperature

- mechanical shock and vibration

- direct sunlight

* For details, see “Specifications” on page 33.

Operation

- Do not move the drives while they are operating. It may cause malfunctions.

- Avoid exposing the drives to sudden changes from low to high temperatures. This may cause condensation to collect inside the drives. If the ambient temperature should suddenly rise while the drives are turned on, turn them off and wait at least one hour before turning them back on. If you attempt to operate the drives immediately after a sudden increase in temperature, malfunctions may occur.

- Turning off the power to the drives while they are writing to tape may cause the tape to become unreadable. All previously negotiated parameters will be lost, whenever power to the drives is cycled.

Transportation

- Keep the original packing materials to facilitate safe transportation of the drive.

- Always remove the tape/media cartridge before moving the drive. After removing the drive from the computer, repack the drive into its original packing.

5 Before the manual ejection procedure, tape slack must be removed in order to prevent tape damage. Rotate the gear mechanism located on the bottom of the drive counterclockwise to tighten the tape.
6 After the tape slack has been removed, continue to turn the Loading motor shaft located on the bottom of the drive clockwise with a precision screwdriver until the tape cartridge is lifted out of the drive mechanism and is ejected.
7 Return the drive to Sony for repair.

WORM Function

The AITi520, AITi260 and AITi130 support the WORM function. This section explains the WORM function.

What is "WORM"?

“WORM” is an acronym for “Write Once Read Many”, a function that allows data to be written to the same place on a tape only once, but permits that data to be read from the tape for any number of times. The AITi520, AITi260 and AITi130 support WORM cartridges. When a WORM cartridge is used with an application that supports the WORM function, data that has been written to a tape can not be accidentally deleted or overwritten.

A WORM drive operates in the same manner as a non-WORM drive when used with a non-WORM cartridge (henceforth referred to as “regular cartridge”).

The operation of a WORM drive and a non-WORM drive differs according to the type of cartridge that is being used.

Tape Drive	Cartridge
	Regular Cartridge (without WORM logo)	WORM Cartridge (with WORM logo)
Non-WORM drive	Read/Write Enabled	Waiting for Eject
WORM drive	Read/Write Enabled	Read/Append-Write Enabled

WORM Cartridges

WORM cartridges can be distinguished from regular cartridges by their WORM logo and red shutters.

Red WORM logo

AIT-2 WORM cartridge: SDX2-50W
AIT-3 WORM cartridge: SDX3-100W
AIT-4 WORM cartridge: SDX4-200W

How to Write Data onto a WORM Cartridge

As with a regular cartridge, there is no limit on how many times data can be read from a WORM cartridge. When writing data to a WORM cartridge, the data can not be written to a portion of the tape that has already been written.

When writing data onto a WORM cartridge, it is appended after data that has already been written onto the cartridge. Accordingly, move to the EOD area before writing data onto the cartridge.

SCSI Commands Supported by the WORM Drive

The WORM drives support the same SCSI commands that are supported by non-WORM drives. However, if an attempt is made to write to a portion of a tape where data has already been written, the following error information is returned:

“Sense Key = 07, ASC = 27h, ASCQ = 00: Persistent Write Protect” or “Sense Key=03, ASC=27h, ASCQ=04: Write Position Error.”

AIT WORM-compliant Software

To find out whether your backup application is AIT WORM compliant, contact the manufacturer of the software.

Notes

• Sony cannot accept liability for data written onto a WORM cartridge that is lost as a result of using this unit.
• Sony accepts no responsibility for any financial damages, lost profits, or claims made by third parties arising from the use of this product.
