My Passport WD 25E1 - not working when plugged into Car USB Slot

Hi,
I bought My Passport upon receiving advice that it was a great way to carry my mp3 collection for playing through my car radio system. I am using my 1TB Drive and plugging it into the USB port of a Vauxhall Astra Elite.
The radio system is a CD500 model. When putting a normal USB stick in the port - all is good and the music plays fine. When I plug the WD My Passport into the same slot, I get a message saying that the DEVICE IS NOT RECOGNISED. I have re-formatted the My Passport to both format options and have not had luck with either. The USB Stick is formatted to FAT32.
Can someone explain why I cant get My Passport to work ?
Thanks
Ian

Check the partition type. It probably needs to be MBR, as opposed to GPT.

The USB port might also not be providing enough current to operate the drive properly.

The MyPassport needs significantly more juice to get it up and running than a USB stick does.

So I’m certainly not an expert on the Vauxhall or their Navi systems, but doing some googling, I came across this forum:

http://www.car4play.com/forum/post/?t=7347

Second post in the thread says " Only MP3 players and USB drives
with a sector size of 512 Bytes and
a cluster size smaller or equal
32 kBytes in the FAT32 file system
are supported.
■ Hard disk drives (HDD) are not
supported.
■ The following restrictions apply for
the data stored on an MP3 Player
or USB device:
Maximum folder structure depth: 11
levels.
Maximum number of MP3/WMA
files that can be saved: 1000.

So maybe it just ain’t going to work with any HDD.

Thanks Tony,
