Help !

Great idea and likely the best result.
Hopefully as you go through the process you will find some to "cull" at the same time and also find some treasures that remind you why you bought them in the first place.

At this stage I have no idea how the drive was formatted but it worked ... Lol.

Any of my networked devices like my pair of Chromecast Audio streamers also see the ex-Vault music hdd connected to both my win10pc and even the USB flashdive in the Ayre with the selected albums I transferred.

Let me clarify as I must have explained poorly.

I sold the Vault a while ago.
I made a USB hdd copy of its contents.
Connected this to a Win10 PC.
JRiver was able to read, play,catalog etc everything on it.
I was then able to copy albums from this USB hdd, using JRiver through the win10 pc to another USB thumb drive.
I was able then to take said thumb drive over to my Ayre EX8 and insert unto one of its USB ports.
Using MControl ( Ayre app to control) I could read and play albums on this thumb drive through the Ayre EX8.

Hope that helps.

Interesting on the ext4 info.

As I said JRiver was able to read, catalog, play and even rip back to a cdr again my copied Bluesound Vault drive on a Windows10 PC.
And I made a USB thumb drive with selected albums from it to play on my Ayre EX8 direct from one of its USB ports which also works just fine.

I sold my Vault but still have the backed up hard drive with all the ripped CD on and still have all my original CD in boxes up in the loft.

So I am real glad JRiver could read it as saved me having to rip them all again.

My experience is between 6 and 8 minutes for good condition discs.
Scuffed and scratched one's can take a fair bit longer as it has to read and re-read over and over.

So yea maybe 10 minutes on average taking all into account

I would have to respectfully disagree on 1500 cds taking a long time to rip.
Or being a lot of work.
I ripped just over 2500 cds into my Vault 2 and it really did not seem too bad.

Additionally I was able to make a back up copy of the lot to another USB hard drive and my window 10 PC running JRiver was able to read and catalog them all. So does not seem to be proprietary to just Bluesound.

Also gave me ample opportunity to cull the herd!

Of course " long time" is extremely subjective!

Salvation Army would take them , most charity shops would.

But I along with Greg interpreted your initial post as just wanting to get rid of them due to space.

So as a huge former Bluesound Vault 2 user I would have suggested that in an instant.

But that still raises an interesting question.

If your concern was truly space then once you have ripped them, well then what are you going to do with them?

Or do you have space in the loft to box up and let them gather dust like approx 90% of mine are now doing?

Take to local Salvation Army shop, let them deal with them

Sorted!
