Hello all,

I recently bought a Attache 512mb usb flash drive from Best Buy yesterday and when I plug it into my MacBook Pro, OS X doesn't recognize it. It doesn't pop on to the desktop or anything. Is there something special that needs to be done for it to work properly?

I am running OS X.4.8 by the way.

Thanks for any help.

USB Flash Drive Not Recognized on Macbook


I am having the same problem. I have the attache 2G USB memory stick which works just fine on my PC at work, and also works perfectly on my imac G5 at home. I just bought a macbook and the laptop won't recognize it. I can see it when I open Disk Utility, but I cannot open it or access anything that is stored on it. The format is MS-DOS (FAT 32), which is supposed to be compatible with PC and Mac. Can anyone help with this?

Thank you very much!!
