    I've been using it on my other windows computer for a couple of months. Naught wrong with it, but when I put it on my mac air it is read only? Tried every menu I can find, but no idea how to make it writeable.

    its probably been formatted in ntfs which mac s can only read not write to without third party software.
    youll need to either format it to fat or the mac standard or create a partition on it so you can use it with the mac

    as slaterry69 has pointed out, the drive is most like in NTFS while OS X uses HFS+, if you want the mac to write natively to that drive, you will need to (first save the data on the drive) format it to FAT so that both the Windows and OS X can write to it (but each individual file can be no larger than 4GB)

    Finder>Utilities>Disk Utility

    Of course, if you no longer have a Windows machine, you can format it to HFS+

    More information re filesystems for the MacOS here.

    Yep, the ext HDD will need to be re-formatted (losing your data!!) by MacOS. Note that 10.6.5 (latest) supports exFAT - and the 4GB per file limit is gone.

    is exFAT compatible with windows 7? So that I can use the drive on both my mac and windows machines.

    So just use xfat and then it's cross platform and I'll have no issues with max file size?
