HP LTO 4 FC “3h-MEDIUM ERROR” on page 62 . Also see the Media Access, reporting this sense key

Code Sense Key	Interpretation
2h NOT READY	This sense key generally means the host will have to wait for the
	drive to become READY. Media access is not possible. See
	“3h—MEDIUM ERROR” on page 62. Also see the Media Access
	pre-execution check.
	Action: The host needs to take one of the following actions:

•Wait until the drive becomes available.

•Issue some type of initializing command.

•Perhaps instruct the user to put the drive online.

•The handling of this sense key will depend upon the host’s operating system and the additional sense code.

Console Message: Drive not ready - media access				not possible
3h MEDIUM ERROR This sense key indicates a failure that is probably due to a problem
	with the tape. The I/O did not complete. The I/O may have been
	partially attempted and data on the tape may have been altered.
	The drive will have retried an optimal number of times before
	reporting this sense key.
	For additional sense codes, see “3h—MEDIUM ERROR” on
	page 62.
Action: Recovery depends on the operating system or application. At the
	very least, whatever the additional sense code, the software should
	log the error, terminate I/O to the drive, and pass the appropriate
	error to the calling application.
	On read, the driver should discriminate between hard read failures
	caused by the media, and those resulting from an inability to
	decompress data.
