Test Unit Ready; Verify - IBM Ultrium Internal Tape Drive T200 Reference Manual

TEST UNIT READY

The TEST UNIT READY command returns Good status if a cartridge is loaded and
ready.

VERIFY

The VERIFY command is supported by all drives.
The VERIFY command causes data to be read from the tape and passed through
the drive's error detection and correction hardware to determine whether it can be
recovered from the tape. The amount of data to be read is indicated by the
Verification Length field and the Fixed flag in the same manner as is used in a
READ command. (See "READ" on page 42.)
The Immed and BCmp flags are not supported and must be set to 0.
