How to restore my iPod Classic 160
I have an iPod Classic 160. I connected it to my Macbook Pro to sync some podcasts but the iPod did not show up either on iTunes (12.7.4.80) or on the desktop. The iPod itself said it was connected and to eject before disconnecting.
Eventually iTunes put up a message saying that the iPod was corrupted, and to either disconnect/reconnect or to restore. I tried the solutions in that order. However even when the software was extracted the iPod would not restore because it was 'busy'.
I got as far as the homepage, and settings tell me that I have 0 space free, 143gb used but none of it is music, it is all 'other'.
I've tried all the support help topic suggestions but to no avail.
iPod classic 160GB (Late 2009), OS X Yosemite (10.10.2)
