Hey Guys,
Had the same problem all of you are having and none of the solutions here worked for my juke. But I did figure it out and now it works great. So if none of the above worked for you, here's what I did.
1. Plug in the juke to the mac (it will show up as "telechips" as usual"
2. Go to "Applications"
3. Go to "Utilities" Folder
4. Go to "Disk Utility"
5. In the "Disk Utility" window select the "1.9 GB SAMSUNG SCHU4..." drive
6. Select the "Partition" tab
7. Under "Volume Scheme" change the drop down menu to say "1 Partition"
8. Select "Mac OS Extended (Journaled)" from the "format" pull down.
9. Click the "Partition" button at the bottom of the window. (this will partition the drive and allow your mac to better connect to it. It will also delete any songs you currently have on it, so you will have to readd them)
10. Eject the disk from finder (drag it to the trash)
11. Unplug you juke
12. Plug you Juke back in.
13. Now the newely partitioned drive will show up as "Telechips" as normal and you can drag your mp3, aac, or wmv files into the "Music" folder
14. Eject the drive from finder, unplug your Juke and enjoy your new music.
no need to do this everytime you add music. After you do it you can just plug in the Juke, drop in files, and eject.
I wouldn't suggest doing this method if you ever plan to add music to your juke from a pc as it created a partition for with mac drives, but if you have a mac and that's where your music is, you are ok.
let me know if this helps anyone.
