Patiot 64GB - PASF64GAUSBG - Recognize issue

[Senor Pena]

I have two of these Patriot 64GB flash drives for MP3 storage & play. I have a USB & iPhone docking radios in several rooms & I have a USB capable radio in my vehicle. So I can take a flash drive & install it on every device for listening. Here is the issue:

I transferred all my MP3's to both 64GB drives - my PC (USB 2.0) recognizes the flash & the files (this is the PC that I store all my MP3s on), my daughter's Apple MacBook Pro recognizes the flash & lists all the files BUT

My work windows laptop (USB 2.0) will not recognize it & in fact states it needs to be formatted but the laptop fails to format it when I tried. My USB enabled radios will not recognize the drives & cannot read them but will accept 32GB/16GB/8GB sticks that I have.

Any ideas here as to what is going on?

I have used my home PC (USB 2.0) to reformat both the drives twice - reloaded the files - same result. My last resort as I write this is to reformat with the HDDGURU low level format software with hopes that this will somehow "fix" whatever is causing my equipment not to recognize the Drives. Any & all help is appreciated as I am in the middle of a music project that has a short deadline.

Hello,

It sounds like a file system compatibility issue. What file system do you have the drive formatted in? Fat? NTFS? Journaled? To check this, click on the drive properties. The most compatible file format we'd recommend would be Fat, although you would be limited to transferring files smaller than 4GB.
