Question ID: 331959
I own an old Sony movie camera that was one of the first ones to use a
cd (a very small cd).  The cd fits inside of a square case similar to
a floppy disk.
The disk is called "Sony MDVIEV-Rewritable MD DATA2 650MB.  I have
accidentally erased the movie that is on 4 of these disks.  I know
that different companies make both hardware and software to recover
from this, but I don't know where to even start to find one that fits
this size of disk.

Hi scuba1-ga:

The name for the media format you are referring to is MiniDisc, a
media type that was popularized by Sony (and to a lesser extent,
Sharp) with their MiniDisc audio players. There was a time when Sony
was using this format in everything in an attempt to make it the new
standard, and they successed to a certain extent in parts of Asia.

One challenge with the MiniDisc format is the lack of support for an
unerase feature. When you accidentally erased the movie, the first
thing that happened is that your camera over-wrote the table of
contents (TOC) to indicate that the MiniDisc has free space where the
movie data is stored. Assuming that you have not subsequently written
anything else to these MiniDiscs, technically the data is still
there... but there is no way, using a standard MiniDisc media
controller, to access it.

If the movie is important enough to you, then it may be worthwhile to
use the services of a data recovery service, as you have mentioned in
your question. I can provide you with links to some of these services,
however there is no guarantee that these services can recover the
whole movie. Since these will simply be links to services that are not
guaranteed to be successful, this most likely is not worth the $50
list price you have provided. Please advise whether you would like
these links, and what you wish to reprice the question to for this, so
that I can formulate an appropriate Answer.

Incidentally, to be more specific, the MiniDisc type you have is not a
standard audio MiniDisc, it is a special high-density type that Sony
manufactured specifically for use with their camcorders, and is not
generally used by anyone else. So, the challenge here is that not all
services that advertise the ability to recover data from MiniDisc, can
handle the high-density type.

AHT  -  Not your fault that there is not much out there on this one.  The $ 50.
is for the question, which does not have a worth by the # of words for the 
answer.  For you and your continued positive attitude I would like to leave you
a tip.  I'm not sure how to do this from here.  Please assist.  

Thanks and have a good day.         Dave

Hopefully one of my fellow Researchers will be able to find the right
stone to turn over to reveal the solution needed here. The UK firm,
ESDL, is the most likely to be able to help with this, but again, the
equipment necessary to read the MD-View format is so rare that I have
a lot of doubt. If there is anyone following this thread located near
this company, perhaps they can do you the favour of contacting them by
phone to ask if they can unerase a MD-View MiniDisc:

I thank you for your offer of a tip. As you've already seen, tips can
only be given in relation to an Answered question, and this question
needs to remain open in the hopes that someone can uncover a good
solution for you. If you wish, you may create a new question addressed
specifically to me (example, subject of "For aht-ga: related to
Q#331959") that I can then 'answer' by referencing the information I
provided here. That way you can set the list price to whatever level
you feel is appropriate; as the Researcher, I receive 75% of the list
price, and 100% of any tip that is provided during the rating process.

Actually, given the increasingly lower probability of success that I
anticipate these recovery services will have in recovering data from
an MD-View format MiniDisc (since the equipment for reading MD-View
MiniDiscs on a computer is next to non-existent), here are the two
most-likely recovery services for you:

http://www.esdl.co.uk/

http://www.vogon-international.com/data%20recovery/emergency-00.htm

They both claim success and support for MiniDisc formats... but
neither mention anything about the MD-View sub-format as being
supported. You will want to contact them directly yourself to see if
it is worth sending your MD-Views to them to try. Given that new
MD-View MiniDiscs are now apparently only available for sale in Japan,
you may want to think a while about sending off four of these
MiniDiscs to a recovery service, in case they are not returned:
