    External harddisk
    Hi

    I've bought an external harddisk and connected it to my Mac.
    Unfortunately it won't let me store files. I don't have permission.
    In the Info window I can see that I'm only permitted to read and do not have the option to change my permission.
    Any suggestions to what I can do?

    Could it be formatted for NTFS? Macs can't write this format. If so, use Disk Utility to reformat it to HFS+ (the native journaled Mac format) and then all will be well.
    My Macs: iMac 27" 3.4 GHz, Mac Pro 3.2 GHz, PowerMac G5 Quad 2.5 GHz, G4 Cube with 1.2 GHz Upgrade
    My iStuff: 64GB iPhone 5, 64GB iPad4, 30GB iPod Video, 16GB iPod Touch
    My OS': Mac OS X Lion, Mac OS X Snow Leopard, Mac OS X Tiger, Mac OS 9.2.2, openSUSE 10.3

    does that mean that a mac can read the data on a (windows formatted) external hard drive?

    that would be great news since i was thinking on how to migrate data from the pc i currently use to the mac i am intending to buy shortly...

    Macs can read/write to FAT-32 formatted discs but not NTFS. NTFS is read ONLY without 3rd party software.

    You can reformat the drive on your Mac to FAT-32 by using Disc Utility. Make sure you select MD-DOS as the format.
