flash drive and car radio help

I have a new sony head unit in my truck and i has support for usb devices to stream music. It said it would work with a sandisk cruzer, and it did, it was working fine. Then i formated it for some reason to delete all the contents and now the radio does not support it. It just gives me an error. Is there anyway to reformat the drive to its original file format? Thanks

Did you contact the device mfg or check their website ?

What was the original file format ?

FAT ...

In general,

* Car Radio systems will read only FAT16 or FAT32 formatted USB sticks.

* You can load only MP3 or WMA files, some also accept AAC.

* There is a limitation as to how many audio files you can put in a USB device - not more than 255 per directory (root is also a directory), not more than 511 files including the directories.
