hard drive - Convert External HDD via USB as Removable Disk

I have an external HDD (500GB) that I took from a laptop and put it into a casing as an external HDD with USB 3.

And also I have a car which can use a USB flashdisk as a media source such as movies and music.

The external HDD I would like to plug into the car but the car only accepting removable disk as media source and no matter what format (NTFS, FAT32, ExFAT) I put into the car it's still not recognized as a media source.

Is there a trick to make the external HDD as a removable disk so I can have the external HDD as media source for my car?

• External HDD in PC is showing as LOCAL DISK, I figure if I could convert it to as removable disk, the car would think it's a removable flash disk.
