One more time: this looks consistent with some sort of failure to transmit the sound data correctly to the drive. Are you certain that you got the 64-bit driver working correctly? I could imagine the machine getting in a tizzy if somehow Windows tried to run data through the 32 bit driver.

No idea, sorry. The current diagnosis is too vague to pinpoint such a component.
I will at some point see if there are schematics but I'll be stabbing in the dark. 5 hours is a very long time for any sensible RC time constant!
Without being a whiz like you, I thought from the bird's eye view that USB connectors can take power and get hot. Over several hours...?

All good information
I'm wondering about the USB circuit itself..... Kevin?
-
Indeed interesting. I gave up on owning a pro deck the day I got my Behringer 2496 Ultramatch Pro, which allows you to take any S/PDIF signal (coax or Toslink) and set whatever bits you want in it for output. Mind you, I don't have Kevin's use case (remote control in real time).

Good morning Aaron.
I need to understand something. Where is this sound (your recording) coming from?
When you play a NetMD track, the sound cannot travel over USB to anywhere at all. You must connect either headphones or an analog cable to one of the two 3.5mm jack sockets on the back of the device. This appears to be a severe limitation for the NT1. See page 6 of the MDS-NT1 user manual.
BTW no need to upload the manual, everything (Service and User manuals, both) at https://minidisc.org/part_Sony_MDS-NT1.html
OTOH, if you can record something on it successfully, the recorded disk should play wherever you want. But..... this presumes that you got the connection TO the NT1 correct, flowing with USB data from PC to MD deck. How did you do that? Did you set up the 64-bit driver in Windows? If not, expect some very strange results.....
Kind regards
Stephen

(ps Anyone heard from @sfbp recently? I hope he’s ok. I PM’d him recently but didn’t get any sort of reply which is unusual).
I'm definitely here. A bit quiet as I am recovering from 3 weeks' hard graft after the ransomware attack (thankfully not my own systems).
The only odd thing is, no sign of a PM (nor an email since you know my address). Try again?

Sounds to me like this is what happens when you try to connect one of these 910's with a USB plug. You need to use the Sony charger that ends in the very narrow circular cross-section 3V plug. Why it's stuck there in "PC<<->>MD" mode, I have no idea.
-
Ahhh ... gears with bent teeth. Sounds like a job for someone with a 3D printer and some skills that I, for one, do not have. But there are folks here who've made bits and bobs like that.

I'm so sorry - I missed 470.... was thinking 770
Upgrading the 470 to have optical out is not very hard, a $5 optical transmitter and a couple of wires. If that interests you we can point you in the direction of someone who did it.
-
What one of these PS's does with a meter across the terminals is neither here nor there. It's what happens under load.
Kevin will probably correct me, and Gyula undoubtedly would have, but I think the only damage will be to the charger.
-
No. The only way is with a computer equipped with optical IN socket. The kit will not help you.

Indeed.. (re)bonjour Philippe!
Sounds like a good idea 👍
So far I have refrained because I don't want to panic everyone resulting in the death of the site.
The easiest way is to get an automatically generated one which is saved automatically, eg by Firefox but I am sure there are lots of options. The important thing is NOT to use the same PW in multiple places. If there's anything you care about, that is, on any of them.

And I see I'm back to being a Newbie. Nothing like the digital age to keep one humble 🥳

Sort of. The supplied USB cable was broken, that was easily sorted. Need to install M-Crew on some suitable machine, plus the USB drivers. I did try with our main Win10-64 machine and whilst M-Crew would install and run, it couldn't communicate with the device so I guess the required drivers are missing. I think I'll need to install it all on an old XP laptop to have any hope of it working. Also I note from this page that use with the 770 requires a firmware upgrade. I'm not sure if the PCLK I have is already upgraded or if the required firmware update can be found anywhere. Plugged into the 770 nothing happened, although with a replacement USB lead at least the TOSLINK LED on the PCLK lit up.
Dunno. Needs some more faffing about with. Any tips and sources for software appreciated!
You'll definitely need a 32-bit version of Windows. Windows 7 does fine - the problem I had was the old laptop had a 1.1 USB socket and so the whole thing really couldn't keep up with the data, by the time you factor in the old, slow laptop hardware.
I think a "custom" win7-32 on a tower of some sort might be reliable. My 770 worked fine with MCrew last time I checked.
-
I'm *really* surprised there's a difference in the charger. Wouldn't the major difference be that the plug shape is different for the different models?
Stephen (who blew up his 110V GP gumstick charger by plugging it into 230 volts when on holiday - never again).

OMG Sony Insiders is back... What has happened @sfbp Stephen ?
Still waiting to hear the inside(rs) story........
We did have a report just before the site went down that it seemed likely all passwords were compromised. IF you use any password here on some other site, you had better change both pretty quickly.
Nice to see you, too Philippe.

Good stuff Chris. So nice to have the familiar portion of my desktop occupied once again.

You da expert.... I mostly gave my bird's-eye view.
I think the codes for MD are common and started with the unpublished SIRCS specification (this was Jim's contribution).

Yes it seemed to have an annoyingly short life. MD-wise it seems to appear on the 920 (but not the 520) which would be 1998, lasting though the x30 range and I think the 770 (2001) was the last. Not sure about the 640/940 without downloading the manuals. So maybe 8 or so MD decks? CD decks seemed to just drop it, and MD decks migrated to USB and PC-Link connectivity, rather than deck-deck connectivity.
Taking issue with this statement. I think that A1(II) and PC-link are essentially identical. (Where's NGY?) When they finally moved to NetMD (USB) that is when the Ctrl-A1 stuff disappeared.

I run firefox on Android and that much works. I agree that "native mobile mode" sux for SIF/IPS.

Not to be a curmudgeon who's missed the point of the complaint, but did you try desktop mode?

The best way to blank a disk completely is to acquire a portable with a busted OW head, so that at the first attempt to write the disk it is completely "empty". Just be careful that said unit is kept in a locked cupboard so nobody even your can take out and try to use by accident. First time you press Track Mark..... booooom!

If you've read the history they actually started manufacturing in a barn that had been used previously to make ploughs and other agricultural equipment. Not sure if that's relevant to audio quality tho (:
-
Ha! Mine came from the *actual* Kent Engineerng Foundry. Chorales. I saw a review of them a few years back from someone in NY who said they easily matched speakers costing thousands today.
Need suggestion to fix MDS-NT1's problem that it can transfer a song but no sound from a disc when playing
in Minidisc

Great, you got the driver, all is good.
That's a 100V adapter. Are you in Japan? I didn't check but I didn't think there were many places outside Japan that used 100V mains. Kevin would have a better idea about this, but putting a 100V adapter in 120V (that's ours here, right now) might WELL cause some overheating possibly just in the power supply itself.
