features:
❏ Floppy disk drive with a 2

×

read/write speed.

❏ Comes equipped with a

“Memory Stick” slot.

❏ The drive is powered by your

computer’s USB connector, so
there is no need to connect it to
an external power source.

❏ Has a compact, lightweight

design for portability.

Because the drive is a high-
powered device (bus-powered;
draws 500 mA of current or less), it
may malfunction if the power from
the computer is not stable.
Therefore, the drive operation is
not guaranteed in the following
situations.
• When using the drive at the same

time as other high-powered USB
devices such as hard disks, CD-
ROM drives, scanners, and
printers.

• When multiple drives are

connected at the same time.

• When using the drive at the same

time as a bus-powered hub.

• When you insert a “Memory

Stick” at the same time a floppy
disk is being accessed. (Before
inserting a “Memory Stick” make
sure that the floppy disk busy
indicator is off.)

• Connect the drive directly to your

computer’s USB connector (root
hub). Operation is not guaranteed
when you connect the drive to
other bus-powered hubs such as
keyboard hubs.

Before consulting your Sony representative, verify the following. If you are
still unable to identify or solve your problem, consult your retailer or Sony
representative.

• If the drive interferes with the

reception of radio or television
signals, move the drive away
from the radio or television.

• When using the drive, do not

wrap it in cloth, sheets or covers
as this may be the cause of
malfunctions or fire.
