I am not able to mount the disc on the desktop in my Macintosh because the disc is "parked".

Hard drives are no longer parked, therefore, this may be a standard error code for the software. A lot of hard drive problems are resolved after using Apple's newest version of Drive Setup. You can download it from the following Apple web site: http://asu.info.apple.com/swupdates.nsf/artnum/n11303 . No need to initialize the drive - just select in the menu REMEMBER: BACK UP ALL OF YOUR DATA BEFORE USING THIS UTILITY. Most of the functions this utility performs will erase any data on the drive. Seagate is not responsible for any data loss. Seagate does not support this utility and cannot attest to its suitability. Contact Apple or your system manufacturer for more information or support on this software.
