- Connect the thumb drive directly to the printer USB port. Don’t use a HUB for example.

Workable USB drives on computers fails to play DIY playlist in car’s system (head unit)
A lot of users use the USB drive to store music/ tracks from iTune/ the computer and play it on vehicles. Sometimes it happens that the tracks are saved on the flash drive but fails to play on the cars. I would suggest the users who ‘d like to make a DIY playlist on cars, please learn the following points:
- Normally computer reads FAT32/ exFAT/ NTFS, but a lot of car USB reads FAT32 only.
- Computer reads more formats of music while cars read MP3 format generally.
- Some head units comes with maximal readable memory size limit up to 4GB capacity.
If you have already come across issues with playing tracks on a car, please follow below steps to check:
1. Format the USB drive as FAT32. Make sure to back up the music before re-format action.
2. Check if the music (song) is in MP3 format which vehicle and computer both support.
3. Please check maximal memory size readable by the head units.

T3: Drive Detected But Not Accessible On Windows
If a drive is detected but not showing up on Desktop nor in My Computer, Please follow below solutions:
Method 1. Reassign a new drive letter to the USB
- Press “Windows + R” simultaneously, input “diskmgmt.msc” and hit “Enter” to open Disk Management.
- Locate the USB disk partition, right click it and choose “Change Drive Letter and Path…”.
- In the pop-up window, click “Change” and assign a new drive letter to the partition.
Always remember that you must assign the name which is not being used by any other drive.
Once drive letter name changed, your USB drive will show up in My Computer and you will able to access data from it. If not then reboot your system and then check.
Method 2. Run CHKDSK to ensure there is no bad sectors on the USB
If the USB flash drive is corrupted or there are some bad sectors on it, then you could not access it, either. However, you can try to run CHKDSK to fix it.
- Click the Search box, type “cmd”, right click Command Prompt icon and select “Run as administrator”.
- In the Command Prompt window, type “chkdsk g: /f /r /x” and press “Enter” (where the “g” stands for the drive letter of your USB flash drive.)
Method 3. Reformat the USB to a compatible file system
If your USB is formatted to be Ext2/3/4 file system, then you be unable to open it in “My Computer”. That’s because the Ext file system is not compatible with Windows operating systems. So you need to reformat it to other compatible file systems, like FAT32, NTFS, exFAT. You can format it in Disk Management.
Warning: since formatting will erase all data stored in the USB drive, please back up your data before formatting.
T2: Use the drive on both Mac & Windows

WARNING: Backup your data. Formatting will delete all the data in your device.
SOLUTION 1 – Format in exFAT
exFAT file system that allows a single file larger than 4GB to be stored on the device. This file system is also compatible with Mac.
Windows 7 and Mac OS 10.6.6 and higher are compatible with exFAT out of the box. Older operating systems may need a patch installed for exFAT compatibility.
