I have a Gateway USB device that I used for storage first on my Mac and then on a PC.  After use on the PC, I was unable to re-open the USB on my Mac.  In fact my mac can't read the USB at all when I try to  load it.  How can I restore my data, or at least get my USB to work again on the apple?

Does the Mac recognize the device at all...does it insert it into finder?  You might try formatting it as a FAT32...I believe that both Windows and the Mac recognize that format.

It recognizes it, but it no longer comes up with the icon for a USB... and I can't open it at all.  How would I go about re formatting it?  Is it possible that it was re formatted  somehow when I inserted it into the PC ?

No, I wouldn't think that just putting it in the PC would have reformatted it.  So I don't really have an answer for why this would have happened.  Just yesterday I used a Gateway USB storage stick in my Mac Pro to copy some files and it went right back in the PC with no problems.

I believe that you can open the Disk Utility application from the Utilities folder under applications and do an erase on the USB device. If you go to that utility you should see the USB device listed.  If you don't then I would suspect something wrong with the device.  Anyway if you see it you can highlight it and do the erase and you should be able to select MSDOS (Fat) as the format type.  You could also put it back into the PC and if it sees it there do a format on it from Windows.

I'll try that...if not I may just have to buy another device.  
Thank you!
