    Hi,

    I've just bought a Mac Mini a few days ago after finally making the switch from windows & so I'm still very much feeling my way around the Mac world.

    I have a Samsung 500gb usb powered external drive that I usually have attached to a Western Digital TV Live unit which is connected to my TV by HDMI which worked fine when I was using it on my PC to copy files to.

    On connecting it to my new Mac and found i couldnt save files to that drive and figured that I needed to format it somehow so I could copy .avi files to it on the mac and that the WD TV can then read them.

    I've tried a couple of formatting options using the disk utility on the MAC and can now copy files to it but the WD TV won't register the newly formatted drive when i connect it via the USB.

    Sorry for such a newbie query & any incorrect terminology but I'd be real grateful for any suggestions that might help.

    Cheers

    Nick

    I don't know how you formatted the drive, but I bet that the WD TV needs to see FAT 32. If you format the Samsung as Fat 32, the Mac will still be able to read and write to it.

    it sounds like the drive is formatted as NTFS, which natively, OS X can not write to, but can read from.

    You can use disk utility for format as MS-DOS Formatted FAT32, or you can do it on Windows too.
