Device library is corrupted and ask for delete ?

Have you updated to rekordbox 5.4.2? There was an issue with an earlier version that would report that issue when connecting a USB device.

i update it but still same i can keep work with cdj2000 i can see my playlist i can explorer i can play .. but when i plug in to pc i can not do anything on recordbox

Why not use the Library > Backup on the old computer and Library > Restore on the new one? That's the easiest way to move the database.

this is sad exprience for me .. but i use rekordbox like a portable one playlist from my friend pc one playlist from my old pc one playlist where i working and my all playlist on hdd now and just i can play but cant reach..

If the EXPORT device is corrupted, why not just export from the collection to the USB device again?

you dont understand ... my all music in contents folder and there is no playlist information ... if i have a collection somewhere else as backup no problem .. i can export again .. so seems like i can not find my answer here ... i put my usb cdj i take video of playlist and i search tracks from contents folder i build my playlist on folders on pc hdd i never trust rekordbox again ..

How ever CDJ read usb and i keep play working everynight...

in PC gives error ask for delete whole library ... at least i can keep working with usb if i clik yes rekordbox gonna delete all ...  pioneer made two software one for cdjs for one for computers why cdj read why computer gives error ??? worlds biggest absurd question

I have the same problem and it's driving me crazy!! Everything works on the CDJs but once I connect my USB to PC, it says corrupted library in rekordbox, I know it has something to do with export.pdb file on the USB because once I delete it, error message is gone. Please help this is my second time when this happened.

If you delete the export database, the players won't be able to read the contents of the device. That isn't a fix for your situation.

I have same problem "device library is corrupted" surely there has to be an easy way round this problem? Pioneer will you give us a workaround please, ive updated to the latest firmware already, how can I solve this, my rx-2 plays everything the problems rekordbox on my pc, how do we solve this?

Pioneer dont care us anymore ... because..;

i never plug out my flashdisk ... never ever ince 15 year im doing djing as my main job i never do that i never plug out from computer never plug out from cdj's with out stop usb.

how ever i plugin flash disk to cdj's and i see my library playlist everything ok. but when i plugin to pc open rekordbox and aaouu!!!  your disk corruptt bla bla rekordbox wanna delete your all playlists.. sucks..

they can solve it im sure because its work in cdjs just dont work in rekordbox how ever..

same company made this software whats in cdjs whats running on computer rekordbox

we decide to use pioneer dj equpmant and pioneer really big company now.... but they know we start to use cd and usbdisk after vinlys (technics) firt we use denon and numark ... but pioneer was listen us listen our ides and made really good cdplayer but now they dont care us because they are king on dj equimpent bazaar .. who is djs ...

i don't use pioneer anymore i use denon .. when i have events i send my riders that i want use denon players i carry my music library for denon system stable then pioneer

@Bayram > If you're now using Denon, why are you even posting here?

you know why im posting here because pioneer devices has long year exprience of whats have dj's brains and i want to keep using this exprience more.
BUT.
i hope some smart man who has enough responsibilty about devoloping pioneer softwares will read my post and your post too and understand how to find solution for rekordbox (pc&mac)...

as you know my all tracks in contents folder now overs 99999999 track in one folder and i have no any backup how ever in cdj i can see my tracks as playlist and i can keep play if i wanna build a backup in computer what am i do ? do you know ? i have to listen these 999999999 track again and i have to arange by folder like 10 years ago ; Lounge Playlist, Tech House Playlist, Downtempo, House, Commercial bla bla i have more than 15-16 playlist in flash drive and i can still use in cdjs but in (pc&mac) rekordbox ... your device library corrupt...

and lets come second big problem '' S U P P O R T ''
i write my problem to this forum and some one says " restore from backup " do you know how i feel like ''im a stupid man and i can't breath and feel bad'' and you are worlds most intellingt man recommend me '' take breath you will feel good ''

you behaving like we are stupid okay i accept it for begginers but a begginer dj will buy new flash disk event can't think about to write to forum for wait a support. do you understand why im write here '' I WANT USE PIONEER'' but if there is no any support cant take risk keep play with denon better..

I'm sorry you feel that way.
