Unrecoverable Error

If an unrecoverable media or hardware error occurs during the read

operation, the CTS terminates the READ command and returns Check

Condition status. The REQUEST SENSE data is set as follows:

Valid 0 or 1

Sense Key Medium Error (3h) or Hardware Error (4h)

Information

bytes

If Valid=1, depend on the setting of the Fixed bit, as follows:

■ If the Fixed bit is 0, equal the requested transfer length

■ If the Fixed bit is 1, equal the difference between the

requested transfer length and the actual number of

logical blocks read. The actual number does not include

the unrecovered block.

Other bits

and bytes

Depend on the error condition

When the READ command is terminated, the CTS is positioned after

the unrecovered block for a Medium Error or in an undefined

position for a Hardware Error.

Note: In both fixed and variable block modes, the CTS may have

entered the Data Phase before reporting this error.
