Resolved Question

Music on usb Flash stick "flutters"

Nov 5, 2014 11:37PM PST

Have loaded about 20 mp3 files onto the stick (SanDisk Ultra USB 3.0, 32Go). When I play the music on my Windows 7 PC, all is OK, but when I play it on my car radio, the music "flutters" (rather like the needle on a vinyl record constantly jumping grooves). Other usb sticks are no problem on the car radio. The stick is apparently OK, and I have run h2testw.exe with positive results.
Something wrong with the formatting? I used the settings FAT32, Allocation size 8192 octets

You could try other formats.

But you are repeating some prior findings. That is, try it on USB 2.0 memory sticks. Again, some gear falters on USB 3.0 drives.

The "fluttering" is actually a different problem .
Could it be something to do with my formatting values I use on the stick? NTFS instead of FAT32, or exFAT , different allocation size? I repeat, the stick works on the PC, but not in the car radio.

I've seen this on Samsung TVs.

USB 3.0 has been problematic on their products. You can try other formatting but there's something about USB 3.0 and "devices" that seem to expose odd problems like this. Yes, there will be folk that trot out that USB 3.0 is backwards compatible but the real world disagrees.

Sure, try other formatting.

That seems to be it!

Just read in the Audio section of my car's manual, and it specifies usb 2.0 FAT16/32. So that seems to be it. Can't understand why the new 3.0's cannot be compatible with older hardware (radio).
