Hello, Long time MD user saying hello and asking for help!

[AudioArtist]

Hello everyone! My name is Gabriel. I'll be straightforward and honest here. I'll probably never be an often contributing member but I desperately need to recover a disc from the NO TOC issue. I've read through lots of articles from minidisc.org and other places. I have some questions and I will truly appreciate any comments, tips, or responses. You would be helping me out!

So I guess I'll give you a little info about me. (you can skip this)

I got my first minidisc setup in '95-'96 (approx) it was the package/combo MDS-JE320 with the MZ-E33 player. The 320 is unfortunately on the brink of death. I may be able to save it but I've been collecting units that other friends have abandoned so it hasn't been necessary. The E33 player has been through all manner of torture including a very serious car wreck. It still works like a champ! I have several hundreds of hours of material that I recorded stored on MD. All of them still play perfectly by the way!

I have a JVC XM-448BK and a Sony DRE1 as well as several other portable and deck units in need of TLC.
I'm an engineer and I record local groups and I also do mixing and mastering for a few clients. Unfortunately I have also left the beloved MD format in the dust for the most part. I keep collecting these because I've developed a love for the format and because of the odd client who asks, "Can you transfer this?"

What I would like to ask is this;

1-In several TOC Cloning/Recovery tutorials I've seen a list that includes the MDS-JE620 and the MDS-JE-640. I have access to a JE-630. It's not one of mine. Is this model capable of TOC cloning?

2-Is there an updated list of all known models that are capable?

3-Does anyone know how to access the test/service mode of a JVC XM-448BK?

JVC customer service was very friendly with me but basically told me that we don't have access to that info anymore and I cannot find a service manual for that deck anywhere. I seems JVC plays it close to the vest in these matters.

I have a disc from a client that is a really good live recording of Chris Whitley that has no TOC. If you've never heard of him or his music I suggest that you give it a fair listen. I would recommend "Living with the Law", "Dirt Floor", and "Rocket House"

Any help or extra info you could share is greatly welcomed and appreciated. Thanks and Cheers for keeping the love for MD alive! -Gabriel
