I bought a sony mzrh1 around 2007

It was discontinued a couple years later. The software to download & upload files from/to the disc stopped working past osx snow leopard. The windows sonic stage program was absolute garbage. It sits unused in a drawer. Sony refused to open-source their code and the encryption/decryption can't be reverse engineered because you need cryptographic keys.

Don't trust sony. Their hardware may be superb, but they have abysmal execution when it comes to software.

There's an entirely web-native replacement for upload/downloading tracks now https://stefano.brilli.me/webminidisc/ It's based off the reverse engineer minidisc python libraries and, imho, is super impressive. The author even figured out how to dump atrac data off any netMD capable deck (not just the MZ-RH1).

Minor note: ATRAC extraction on non-RH1 models and Hi-MD support is only available on the fork at web.minidisc.wiki (Web MiniDisc Pro).
