[SOLVED] Ejecting USB drive with large library kills navigation for over 2 minutes and causes emergency loop

@BriChi > So when I saw that deck playing a track, the track wasn't from the drive connected to that deck?

correct, I can simply plug the usb drive in, not even play a track and try and eject it and it takes forever and renders the menus useless

Ok, usual questions apply: what make of drive is it? Is it hub powered or AC powered? Have you many partitions on the drive?

it is a WD external

250gb drive, 5400rpm

roughly 200gb of music, 26,000+ mp3's

powered by USB

Tried a 250gb powered external, 7200rpm, same files, same results 

all 1 partition, tried OSX partition and FAT

Did you use the same drive with your original CDJ2000s?

yes, It's been formatted and re-exported since I bought the Nexus players. I have the white 2000mk1's at my house now so I can test if it happens on those also

Yeah, I'd be interested to see if its a bug related to the Nexus or if its simply the drive isn't receiving enough power from the CDJ.

the drive works fine the entire time, can do 4 hour events just off the drive with no issues, it's just the ejecting thats the issue, as bad as that sounds, LOL... 

also I dont think its a power issues because same thing happens with a powered external usb

Woops, kinda forgot the problem was just with ejecting.

I'll tell the engineers you have an ejecting problem and see what they say.

;)

hahahahaha, sounds good!

I have a brand new SATA 250gb 7200rpm powered external, I'll test with that too after a full export, Ill report back tonight with all the tests

I also notice this has nothing to do with the size of the drive, speed, etc..... it's database based somehow. I copied the hidden .Pioneer off my external, formatted it and copied ONLY that folder back which consists of only the "export.pdb" of file in the rekordbox folder, all the other folders are blank so there's only 22mb on the drive total, If i plug in the drive, all the playlists show up and it reads the info (obviously I cannot load tracks though), When I eject the drive it's the same hang time I was getting before. 

here is a copy of that pdb file: https://dl.dropbox.com/u/1184069/export.pdb.zip

ok Gavin, I did side by side tests between the White 2000Mk1 and my Nexus with 2 different drives

drive 1, 250gb/7200rpm, 3.5" WD external with external AC power, 25,000 mp3's, no playlists

plugged in the drive, waited for the tracks to appear then hit eject

:35 seconds to eject on nexus

:20 seconds to eject on white 2000MK1

2nd drive, 250gb, 5400rpm, usb powered, 25,000 tracks and many playlists 

1:45 to eject on Nexus

:40 seconds to eject on white 2000

so you can see obviously on the nexus the same exact drive takes over a minute to eject on the Nexus vs only 40 seconds (which is still a long time) to eject on a MK1

Hope that helps

Just waiting to hear back from the engineer in charge, currently.

@BriChi > Following up, have you noticed any improvement since 1.10?

sorry Gavin, missed this.

No improvement at all

I hit eject on the drive and now the player is dead for 2-3 minutes while it ejects, Even if i try and load a track from a cd or ipad, i just get errors until the USB drive is finished ejecting

also Gavin, I attached the externals export file so they can test this so they should be able to easily reproduce this and fix

We improved the speed of browsing a USB device even in the environment where more than 10,000 tracks are stored in CDJ2000NEXUS compared with that of CDJ2000. 

However, the more tracks you have, the more time you need from the time the USB STOP button is pressed until the necessary processing to safely remove your USB device is finished. 

The engineers will continue investigation and development to provide the customers with better usability.

cool, thank you!
