    Read only file system error with external HDD
    I want to copy some files from my MacBook to an external HDD to take away and run on an assortment of Windows and Apple machines. I have connected a Lacie external HDD to my MacBook that I have used on several Windows machines for back-up of important files. When I try to drag and drop a file into the Lacie icon I get a 'no entry' type symbol and when attempting to 'save as' to the Lacie HDD from the open file I get an error about 'read only file system'.

    Please can anyone advise how I am able to save the files to the Lacie from the Mac?

    Many thanks

    You can't write to the drive because it's probably formatted as NTFS. NTFS is read only from a Mac. You need a third party driver in order to write to the drive. The best one to use is "Paragon NTFS" from Paragon Software $19.95.

    Here is the link for the download and purchase.
