When it is submerged, the white
Water Exposure Seal turns to red.
As the center part of the seal turns
to pink, the color seen from the
hole is pink. The 1mm hole
diameter prevents the seal from
getting affected by wet hands
under normal conditions. It is not
affected by the humidity of normal
storage or operational conditions.

Main unit operation failures caused by the main unit/
Microdrive failures.
2.1.4.2 There is a possibility of a Microdrive being damaged even
though there is no notable failure in appearance.
Main unit failures also result in abnormal operation in a Micro-
drive.
Identifying the causes of the failures in the main unit is explained
in this section.
In the diagram, MD stands for a Microdrive, CG for a compact
flash card, and SD for a SD card.

Operation failures caused by main unit failures
2.1.4.3 Judging from the separation of the main unit and MD, the
operation failure is more likely to be caused by the main unit fail-
ure. However, the main unit failure has not been determined yet,
as there is a possibility of the user MD failure causing the main
unit damage. The following procedure shows how to determine
the main unit failure.

The user MD/ FC may bend the
the main unit housing and
main unit socket pin(s). Using
defective MD/ FC results in
user MD/ CF
repeated failures, as they bend the
main unit connector every time
they are used. User MD/ CF should
be checked when abnormal main
unit socket is found.
Ask how many MDs/ CFs the user
has, then check all user MDs/ CFs.
2.1.4.5
Disabled read/ write with other devices
When read/ write cannot be done with the main unit, the main
unit failure is considered in most cases. Recognition failure
caused by the main unit writing bad data can be considered.
The causes of read/ write failures are as listed below.
(1) Damaged mechanism parts or electric parts inside the MD.
(Hardware failure)
(2) Damaged information in the MD. (Software failure)
In the case (1), it seems very difficult to recover, but there is a
possibility of recovery in the case (2) by using commercial software.
The following procedure shows how to figure out whether the
damage is in the hardware or in the software, and whether it is
recoverable or not.

2.1.4.5.1
Microdrive hardware failure
Although no failure was found in the MD appearance at the time
of the separation of 2.1.4.1, actually there is considerable dam-
age disabling the operation. In this case, "Shipping Damage"
(damage caused by the transportation) is displayed as a result of
DDD diagnosis. Surely, a possibility of the products damaged on
route from the production plants to the shops and then to the con-
sumers cannot be denied.
However, MDs are stored in protection cases or in main units and
the transportation shock that damages only the MDs is unrealis-
tic. A failure cause by the user handling is more likely considered.
Perform an operation check with CF and SD.
Use SD with theoretical value of 10MB/s or more.
Use CF with 40x high speed or more.

defragmentation and check disk done
with a device other than the main unit.
