Recovery method

Asking a data recovery company (a data salvage company)
seems the only way.
Even if the MD is not recognized a drive, a transmission may be
possible with the MD (light hardware failure). In this case, system
recovery software such as Norton Utilities in Norton System-
Works 2004 (NOTE1: ) may help drive recognition.
Once the drive recognition is recovered, the record may be re-
covered by the method mentioned in 4.5.2 MD software failure.
However, if it is a hardware failure, banning the use of the MD is
strongly recommended.

2.1.4.5.2

Microdrive software failure

Most of the software failures are caused by the unrecognizable
MD after user's editing works such as formatting and adding/ de-
leting files or maintenance works such as defragmentation and
check disk done with a device other than the main unit.
Many cases under this condition, recovery can be done by using
recovery software, which can recover MPEG2 data, such as Final
Data 2.0 Premium. It enables the drive recognition and the data
reading. Once the data is recovered, follow the below procedure.

NOTE1:

Norton SystemWorks 2004 (Latest version on 2004/ 9/ 29)
It is Symantec's data recovery software.
For system requirements and other details, please check their
web site.http://www.symantec.com/region/jp/products/

NOTE2:

Final Data 2.0 Premium Office (Latest version on 2004/9/29)
It is AOS Technologies' data recovery software.
Although there are some kinds of recovery software as FINAL-
DATA series from this company, this is the cheapest one that
can recover MPEG2.
For system requirements and other details, please check their
web site.http://www.finaldata.ne.jp/

2.1.4.5.3

Reusing Microdrives

If a Microdrive of a user is reused for another user, normal data
deletion may not completely erase the previous user's informa-
tion (images) and the previous user's information may come
back. Unlike hard disks of PCs, most of the recorded contents of
Microdrives are images and audio data, thus there is a little pos-
sibility of recorded personal information in Microdrives. However,
proper handling in reusing Microdrives is required as a business
organization.

There are levels in erasing data in disks.
• Level 1: Zero Write method (once)
• Level 2: Random Write method (once)
• Level 3: Random/ Zero Write method (twice)
• Level 4: US Department of Defense (DoD5220.22-M)
• Level 5: US Department of Defense (DoD5220.22-Expanded)
• Level 6: Guttmann method
At least level 3 data erasure is recommended.
Data erasure software is commercially available from software
companies. It seems convenient to use Final Data 2.0 Premium
as there is a data erasing function in it.

2.1.5 Combinations of media and a main unit

MC100 - 200 can record movies, pictures, and audio on compact
flash cards, SD cards in addition to Microdrives. Recording mov-
ies is partially limited. Characteristics of each medium, available
or limited operation items, and available operation time are ex-
plained in this section.

2.1.5.1

Types of media

Commercially available maximum capacity
MC100 - 200 are basically designed to record movies by using
Microdrives.
MC100 - 200 have 2 types of slots, one for a Microdrive or a
Compact Flash card, and the other for a SD card.
From the menu, movies/ pictures/ audio can be selected for a
medium in either one of the slots.

As movies, pictures, and audio can separately select the slots,
using one slot for all recording mode is possible. However, as
movies require large capacity and high transmission speed, the
available recording mode (image quality) is limited.
(Refer to 5.2.3 Image quality and support media.)
Recording movies in Microdrive setting is recommended.

2.1.5.2

Movies

Movies are recorded SD-VIDEO1.1 standard, (images) MPEG-
2-PS (with RDI),(audio) Dolby Digital AC-3, NTSC 60 frame as-
pect 4:3
Movie recording is explained as follows.

YES

Further recovery is not expected.
Please explain the user that it is
a MD failure.

Format the MD with the main unit

Perform the DDD Clean Disk

Return the user backup data

Perform a detailed operation

YES

End

Main unit failure

Explain the user that the possible cause
of the failure may be the users PC works.
Check again whether the user did a
prohibited or not guaranteed operation
by the Instruction Book.

If backup is impossible,
do not proceed to the further works.

Perform an operation check on
all items including MD and SD.
