some 15K 600GB disk drives that EMC procures from a 3rd
party manufacturer for use in VNX storage systems. The issue affects disk drives and sections of disk
drives that are currently installed in a VNX system, but are unused. When the drive or section of the drive
is put into use, there is a chance that some drive sectors could be unwritable. In this event, a disk drive(s)
failure may occur potentially resulting in data unavailability and data loss.
