Write-Protecting Tape Cartridges

Quantum Scalar i40 and Scalar i80 User’s Guide 265

• Do not insert damaged cartridges into tape drives.

• Do not touch the tape or tape leader.

Caution: Do not degauss cartridges that you intend to reuse.

Write-Protecting Tape Cartridges

All tape cartridges have a write-protect (write-inhibit) switch to prevent

accidental erasure or overwriting of data. Before loading a tape

cartridge into the library, make sure that the write-protect switch is

positioned correctly (either on or off).

Slide the red or orange write-protect switch to the right so that the

padlock shows in the closed position. The switch is located on the left

side of the cartridge front.

Barcode Requirements

Cartridges must have an external barcode label that is machine

readable. A barcode must use only uppercase letters A to Z and/or

numeric values 0 to 9. The library supports Code 39 (3 of 9) type

barcodes.

The supported tape cartridge barcode formats are as follows:

• Standard Six — Six character barcode number with or without a

one or two-character media ID, for example, “XXXXXXL4” or

”XXXXXX”. Only the six character barcode is reported to the host.

• Plus Six — Six character barcode number followed by a media ID,

for example, “XXXXXXL3”. Six character barcode and media ID are

reported to the host.

• Extended — Five to 15 characters total, including a barcode

number and optional media ID. All characters are reported to the

host, regardless of having a media ID or not. If a media ID is
