Hi, i tried copying directly from finder to the desktop but i get errors, i dont think the file is corrupt cause i can open it and watch the videoclip.
Is there a program like Isobuster for the pc that is on the mac
What do you mean by rip data cds? Create disc images, or just get the data? If you just want the data, click the icon for the cd, hold down the mouse button and press the "option" key, move it to an empty part of the desktop, and let go. Should just copy everything right to your desktop (and, as a result, your HD). If you want it in a specific place, just drag and drop to the folder and it will copy automatically.
If you want a disk image, as stated above use disk utility.
