    are there any mac apps that can format a blank hard drive in an external enclosure to different formats like fat 32, NTFS, & macs native format, I have put together my own external hard drives with 72rpm hard drives in external enclosures & I prefer my drives to be cross platform to use on both a mac & PC.

    Disk Utility. It's in /Applications/Utilities/

    Disk Utility will do the job for you – it's in your Apps folder, in Utilities.

    Thanks, I will look into utilities, When I have the blank drive put together & plug it in for the first time into the mac, I just open up disk utility? or will it open automatically?

    do external hard drives used with a mac need defragging like on windows? will 1 terabyte fat 32 formatted external hard drives work on a mac?

    and some of these hard drives I have been using with windows, should I defrag them before switching & using on a mac?

    If they are HFS+ (Mac native format) then no. If they are a Windows format then whatever the Microsoft recommendation for that format is.

    Typically Mac's don't need defragging
    Disk Optimization

    But there are utilities for it

    Not sure how that would apply to an external disk

    so if it is fat 32 it will need defragging? how would I do this while using it on a mac? what if I just have it connected to a mac most if not all the time?
