I am having issuess with the Denon Prime 4 Unit Reading a Collection…
…on USB …on SD …am SSD for my SATA internal 2.5" hard drive. All formatted exFAT.
I have loaded about 12,000 - 12,750 MP3 320 @ 44,000 at least that is what I started with. Very slow responce on powerup the wheel turns and turns. I then get a Database is corrupt message on powerup.
No searching available for songs available. I have hooked up the laptop and deleted all the songs and loaded the songs through Engine Prime. Still Database Is Corrupt and very slow

Hi Phil.
Strange you have this on all drives.
Are the databases prepared with latest Engine Prime 1.3.1?

Hi @philgaitan,
Sorry to hear this! What if you power the unit on without any media device connected, do you still see the message?

I had this same issue. Formatting in FAT32 (MS-DOS FAT in OSX) fixed the issue.
Large drives (up to 1TB can be formatted to FAT32 in Linux using GParted.

Most of the large format format utilities (such as Tokiwa) build super unstable partitions in windows. Your better to use a USB portable version of linux such as Parrot OS or MInt. Plug in thumb drive, boot from thumb drive, format drive as FAT32 using GParted, restart and use drive with Engine.

Try Rufus - I’ve never had any corruption problems with it.

Rufus can still have issues on partition tables for drives over 128GB. While I’ve never had issues using Rufus on Intel 545S and Crucial MX series SSD’s, I have seen issues using it for other brands (such as Kingston).

Thanks, I use 2x Kingston 128GB USB 3.0 drives so that would explain why I’ve never encountered this issue. I will keep this in mind if/when I upgrade my storage 🙂

[Moving to general area as this is not a bug but a configuration issue]

Hi Jay
I have bought the Prime 4 Unit & installed a 1TB Samsung Evo 860 SSD drive in it All good … Then connected Mac laptop and formatted the drive to exfat as recommended etc… did the software update etc transferred the playlists over from laptop to SSD in the Prime simple enough…
So question here now is once you turn on Prime 4 and you start playing music from SSD in Prime 4 then you finish up and wanna eject SSD but you can’t as there is no way of doing this?? How do you Eject or Dismount the Internal Drive installed the Prime 4 after every Gig???

Windows 10, Prime 4, Engine Prime (all updated), SSD internal.
Hi there, Can somebody please tell me, in this sollution, in line 01 is asked to copy All files on my computer. Does it want me to copy al files FROM the internal ssd TO (on) my computer. Or… does it want me to copy the files ON my computer, in the directory Engine Library. (to paste them later on, in the program sqlitebrowser?)
