CDJ - 850 USB 3.1 Not stable - how to fix!
Hi!
I use Samsung BAR Plus 32GB and have CDJ-850
And i have some problem.
I prepare a flash drive in rekordbox
Then I insert first time flash drive in CDJ - 850 and it's work great.
But if I second time insert the same flash drive in CDJ - 850, it's will freez CDJ.
No one button not be interact with me.
I recorded a video about it - https://www.youtube.com/watch?v=yg0Mh2iLw1Y
After 3th days formating and exequting whit flash drive i found the solve.
Just delete file on flash drive USBMNG.DAT
by path %flash_drive%:\PIONEER\USBANLZ\
And so every time you remove the flash drive from CDJ-850 (about ohter models i dont know)
I opened to read this file and see that have about 25 000 row of information!
And questions to Pioneer:
1) For what this USBMNG.DAT file is created all the time, again and again on a flash drive
2) Can you fix it in next firmware update, pllease?

Unfortunately not all USB drives are compatible with all our players. While USB standards exist, there are often incompatibilities between drive memory manager chips and the USB device host chips. This is not something that can be addressed via firmware and the only solution is to us a different USB drive, or possibly the same drive formatted to a different file system (eg. FAT32 vs HFS+).
I have the same exact issue. I just got a pair of cdj 850's and I had previously purchased a set of Samsung BAR Plus 32GB 3.1 flash drives. I set them up with record box and they are good for one use.. after they get ejected or if you cycle the power on the device from then on they will freeze the cdj and then return the "NO USB" after a short time.
Same problem with my 3.1 USB. Any update pionneer ? This is a known issue since August 01, 2018

Any news? We need a fix..
Yup, same issue here and it's getting really annoying.
So please Pioneer hear us and do someting....
I have the same problem. i bought the Samsung 32gb 3.1 usb and the problem persist.
i don't understand why Pioneer does not continue with the upgrades of the CDJ 850. Why they forget the people that use that CDJ.
The last upgrade that i finded is the FIRMWARE 1.13.
I hope Pioneer try to fix this problem and help all clients who use the CDJ 850.
I have the same problem. anybody know the solution jet??
Pioneer should gave us a solution like a new firmware update
I Have the same problem !!
Hi everyone, has anyone had success?
I am looking into getting a pair of 850’s for myself, but I remember at a few events and this one club I played at who had 850’s I also experienced these problems. Sometimes once a flash drive was ejected I could not use that specific flash drive again that night, luckily I always carried spares.
I have also found the Samsung Fit Plus and the Bar Plus US3.1 sticks do not work that well with the 850’s. SanDisk Ultra Flairs have worked much better, but still had a hiccup hee and there.
Kind regards
