Switching between hard-drive partitions
I have been having problems in moving files from the Mountain Lion section of my computer's hard drive to the Snow Leopard section (I have partitioned the hard drive). Today, I learned how to do it and, as a test, successfully transferred a song from the Mountain Lion's iTunes library to the Snow Leopard's iTunes library. Unfortunately, a new problem then arose: I can no longer switch from one operating system to the other; in fact, I can no longer open in Snow Leopard at all. Previously, I would open in Snow Leopard by powering on the computer, or in Mountain Lion by powering on the computer WHILE holding down the OPTION key. That procedure no longer works.
I can think of only two things that happened today that may have caused the problem. They both occurred while trying to transfer 4,085 songs occupying 16.72 GBs from my Mountain Lion's iTunes library to my Snow Leopard's iTunes library. The incidents were as follows: (1) I accidentally downloaded many of the songs to my Mountain Lion desktop rather than to the Snow Leopard hard drive icon on my Mountain Lion desktop. When I tried to trash the songs to clean up the desktop, the following message appeared: "Some of the items you are moving are in use by another application. Moving the items can cause problems with the application using them. Are you sure you want to move these items?" (2) I transferred all 4,085 songs (16.72 GB) to the Snow Leopard hard drive icon on my Mountain Lion desktop. A little wordy, perhaps, but I think I've covered everything.
