Symptoms:
	PHKL_22377:
	(SR: 8606167324   CR: JAGad36610)
	During a write to a floppy disk, the potential may exist
	for the floppy disk controller to incorrectly transfer the
	last byte of data in a sector if the computer is
	simultaneously experiencing activity on the I/O bus
	sufficient to cause a significant delay in the transfer of
	that byte, but no other byte.  Specifically, the next to
	last byte could be re-written in the place of the last
	byte.  This potential error may not be reported to the
	user.

Defect Description:
	PHKL_22377:
	(SR: 8606167324   CR: JAGad36610)
	It is claimed that a design error exists in certain floppy
	disk controller technology that creates the potential for
	data corruption or data loss during the transfer of data to
	or from a floppy disk or tape device that utilizes a floppy
	disk controller.  Specifically, it is alleged that this
	potential exists when the floppy disk controller is
	transferring the last byte of a sector and only if the
	computer is simultaneously experiencing activity on the
	I/O bus sufficient to cause a significant delay in the
	transfer of that byte, but no other byte.  HP is unaware
	of any customer actually experiencing this error.
	Nevertheless, HP is offering a software patch to customers
	to eliminate the possibility that their computers could
	experience such an error.

	Resolution:
	The software patch eliminates the possibility that a HP
	computer could experience the error described above.  HP is
	recommending that customers visit HP's website at
	http://hp.com/go/fdcpatch or you can call HP's customer
	Service Center at 1-800-742-9729 in order to determine if
	HP recommends downloading the patch.
