    I have a 320gb External Hard drive that i used as my time machine. I now have a 1TB one some my wife is going to have my old one for her PC.

    Its currently formatted as Mac OS Extended (Journaled) would i have to reformatted to MS-DOS (FAT) for it to work with PC?


    Cheers

    Windows can not natively read a Mac formatted hard drive. To be used with Windows (without using third party software) the hard drive needs to be formatted for either MS-DOS (FAT) or NTFS. You can format it as MS-DOS (FAT) on a Mac with Disk Utility but not as NTFS. To format it as NTFS on a Mac you would need third party software as OS X can only natively read NTFS not write to it. You should be able to format it as NTFS using Windows. Here's a MacRumors post that explains the difference between MS-DOS (FAT) and NTFS.

    ExFAT plays nice with recent versions of Windows & OSX

    MS DOS is a relic and has file size limitations. You really want FAT32 or ExFAT (better)
