The values reported for the Ultrium format are as follows:

Table 75. Density Information for LTO Formats

Field Ultrium 1

Primary density code 40h

Secondary density code 40h

Bits per mm 4880

Media width (in tenths of mm) 127

Tracks 384

Capacity (in megabytes) 95367

Assigning organization LTO-CVE

Density name U-18

Description Ultrium 1/8T

The Write Okay (WRTOK) flag is clear if the drive does not support writing to this

format, but does support reading it. This is always 1 for first-generation drives. The

Duplicate (DUP) flag is set to 0 for every descriptor block, indicating that each

density is only reported once. The Default (DEFLT) flag is set for the density for

which the currently mounted medium is formatted and is clear for all other densities.

This is always 1 for first-generation drives, since any given piece of media only has

one possible format.

The capacity values in the table are the maximum values possible and are reported

if the Media flag is clear. If the Media flag is set, the actual capacity for the loaded

tape is reported, which may be less than the value in the table.

Note: For this command, a megabyte is equal to 1 048 576 bytes. Therefore, a

reported capacity of 95 367 megabytes is equal to 100 000 000 000 bytes.
