Pry the ends of the blank outward until the blank is free.
Installing a Drive Blank
The drive blank is keyed to ensure correct insertion into the drive bay. To install a 3.5-inch drive blank,
insert and rotate in the keyed side of the blank into the drive bay and press evenly on the other end of the
