Possible Fix for Unrecognized USB Devices

[Cuitarded]

I just got a 32GB Flash USB Drive. Usually I format my drives NTFS, however I do not believe the Fit USB interface recognizes that format.

Before I had a FAT32 20GB 1.8' drive (in my MP3 player) that worked fine, however when trying to use my 32GB drive I couldn't get it to work.

I tried both NTFS and exFAT formats with the Fit, just to be sure. Neither worked. I then reformatted it back to FAT32. At first I was still getting Unrecognized error. But then I noticed that I usually set my Allocation Unit Size pretty high when I format. To check this, I used a smaller 8GB stick that I knew worked, and it's allocation size was at 4096 Bytes.

Long story short, I reformatted my 32GB stick from 64KB to a 8192B allocation size (couldn't do 4096). Works fine.

Long story short:
Make sure you use 4096 or 8192 Byes as the Allocation Unit Size when you format your drives. Too large and it seems the Navi doesn't like it. I have not tried other larger sizes other than 64KB.

Hope this works for some people!
FYI:
When a hard drive is formatted, it is allocated into chucks called allocation units, and is basically the smallest size that data chunks are stored in. So if you formatted to 8192Bytes, a 100Byte file would take up that entire Allocation size. Larger sizes are, but obviously waste more space when using smaller files.

FWIW, my 09 sport non-navi recognizes NTFS.

Looks like this is an old thread, but just wondering if anyone has gotten a Flash drive larger than 32GB to work with their Fit?

I just bought an 09 non-nav sport. I love the USB feature. I happen to have a 64GB flash drive, but haven't been able to get it to work yet.

I've found mixed opinions or results as to wheter the USB on the Fit can read NTFS. I'm guessing the answer is no, but it sounds like maybe a few people have had success with NTFS.

I am working on partitioning mine so I can format it with FAT32. I gave exFAT a try, but as I suspected since that's a Microsoft proprietary file system at the moment that didn't work either.

Anyone else had any luck interfacing a USB flash drive larger than 32GB?

Haven't tried anything larger, however have you tried playing around with the allocation unit size as I mentioned in my post? If so, which sizes have you tried?

I know it's a little time consuming but it is totally worth it to have all that music sitting in your dashboard : )

Thanks for the reply.

Yeah I tried the 4096 and 8192 block sizes. No dice.

Does anyone have confirmation if NTFS is compatible or not? I'm guessing no. I've mostly been trying to confirm its the file system that my Fit doesn't like and not just my USB flash drive. I'll have to try NTFS on my small flash drive that works just to be sure.

The funny thing to me is that the manual states that anything 256MB or larger should work, but if its only FAT32 compatible they maybe should have mentioned anything 256MB - 32GB is compatible!

Still I love this feature... other than the fact that the file and folder names don't scroll on the head unit display, like many others have mentioned. My wife's Nissan Rogue does scroll which is really nice, although it only reads the MP3's from CD.

All in all the USB interface is killer and super convenient! I'll just have to use smaller USB sticks I guess!
