I own a Technics organ model EX70 with a SY-FD5 digital disk recorder external hard drive. The organ works fine, however, the hard drive doesn't function. I've had 3 computer techs look at it with no results. Could the wiring be the problem? Two local music store also cannot help. Any suggestions? Thanks!

Re: Technics digital disk recorder

Hi danal211,

I guess I'm not going to be able to help you much except for a few pointers because I've never actually used an SY-FD5. And forgive me if I repeat anything you already know...

This is a floppy drive, not a hard drive. It doesn't function without a correctly initialised floppy disk of the correct type.

The instructions for the SY-FD5 are in the Members Area.

All pins of all cables and sockets should be carefully cleaned.

When turned on, you should see an LED light up.

You must ensure that you are using the correct disks - Single Sided Double Density (SSDD) and the disk must be initialised according to the instructions (user manual for he organ is also in the Members Area, you'll need to refer to the instructions in both manuals).

You will probably need to run a floppy drive cleaner in the unit to clean the disk heads.

If none of the above works then you'll need an engineer to look at it and refer to the Service Manual. I don't have the Service Manual so if you have one (or get one) please let me have a copy. If you aren't able to find one let me know and I'll let you know where to get it or source it for you.

Finally, you might be interested to know that there are three SY-P2 Memory Packs listed on Ebay USA at the moment. These packs do essentially the same thing as the floppy drive and are quite rare.

Let me know if I can help further. If you want me to source the Service Manual please use the contact form on the help menu.

Best wishes,

Re: Technics digital disk recorder

Mike's advice is spot-on, but here's something I can add: My PR-60 "Digital Ensemble" had not been played for a while, due to my years of international travel, and when I did finally get back to using it, the response was bizarre. Some notes did not sound at all, and others kept on playing - and playing and playing.

As if that were not trouble enough, when I attempted to load a saved song sequence from the SY-FD5 external hard drive, that operation failed.

Eventually, after recording and then re-playing a random sequence of notes into the on-board recorder (I am a trumpeter, not a pianist!), the piano finally began to perform normally - *most* of the time. However, this did not cure the SY-FD5 problem, and thus I tried various and sundry things to fix it - including completely disassembly and cleaning of the unit, and verification of basic electrical connections; all to no avail.

In the meantime I *was* able to verify that a note sequence recorded into the piano's on-board recorder could be saved to and then played back from the one and only SY-P4 memory card that I own; and this gave me a certain amount of confidence that the problem lay within the SY-FD5, and not within the piano itself.

Thus I ordered what appeared to be a near-identical floppy disk drive (just the basic unit, not the SY-FD5); but that did not fix the problem. Finally, I found listed on eBay a used SY-FD5 - whose seller had no way to verify that the unit worked, or didn't. I decided to take a chance, and when the unit arrived, lo and behold, it worked!

Now I can again play dozens of professionally-recorded piano/organ/harpsichord accompaniments for my solo trumpet music, which is a great relief; but I still wanted to narrow down the nature of the disk drive problem. Thus I swapped *only* the internal floppy disk drive units between the failed SY-FD5 and the "new" one that worked, and found that it was indeed just that basic drive - not the power supply or control board or other electronic circuitry - that had failed.

Accordingly, my advice to you is to continue searching for a known-good SY-FD5, complete, but in the meantime continue to *play* the Technics digital instrument to which it is attached - including making recordings to, and playing back from, any SY-P4 (or similar) memory cards to which you have access. From my experience, this piano thrives on being played, and suffers when it is allowed to sit unused.

Making your whole system work again is a project well worth pursuing, IMO, so good luck to you!

Best regards,
