Hi. Hoping someone here knows what I'm missing here...
I have a Pachanko Labs Constellation Mini SE server/transport, with an internal 2TB Samsung 870 QVO SSD for music file storage. I also have - from an old server DIY project - a 4TB Samsung 870 EVO SSD, which is both bigger and a better drive.
I pulled the 2TB drive, checked its contents, and saw nothing but my music files. I copied them onto the empty 4TB drive, renamed the 4TB drive the same as the 2TB drive, and installed it. However, Roon then couldn't recognize the server.
I opened up the box again, checked the connections, reinstalled it to my system, and Roon still wouldn't recognize it. So I reinstalled the original drive again, which was immediately recognized.
What am I doing wrong?
Thanks!

I had a different problem that I threw Roon in the trash and re-installed a new downloaded Roon and when my Mac was shutdown I had to do it again to fix. I don't know who fixed it but all is well now.

Purely speculation on my end.

Perhaps you need to change a setting in the firmware in the device to get it to recognize a 4TB drive or the device does not work with a 4TB drive.

Thanks for all the suggestions. I finally got it sorted: Apparently when Windows is installed with two drives present, setup happily drops that active boot partition on whichever disk enumerates first — often the SATA drive, not the NVMe. That means that even though the 2TB SATA drive was supposed to be music library only, there was a boot partition on it. Claude-AI guided me through copying the boot files to the Windows drive, which allowed me to boot the machine without either the old library drive or my proposed new one installed. Once that was working, I just installed the new drive, made sure the boot order was right, then had Roon do a re-scan. And we all lived happily ever after!
