iPod classic not showing up in iTunes 12.1.2.27
My iPod Classic 7th Generation model MB565ZP does not show up in iTunes as a device.
iTunes version is 12.1.2.27
Yosemite 10.10.3
The iPod shows up in the Finder window under devices and sometimes the iPod symbol will quickly pop up where the devices show up in the iTunes window (I've yet to create that situation.sequence again that has it show up).
When going to use it after 3-4months its battery was drained (the lock switch was not on). Once it had recharged enough to turn on I found that it had completely been wiped. I'm unsure how this happened. I went to sync it with a backup from my iMac and this is when I have come up with this problem. I looked in the backups for devices in the iTunes preferences and have also noticed there is no backup for the iPod.
I have tried restarting iTunes, iPod and iMac. I have updated all software and also tried two different usb cords and ports.
Please help, I'm really hoping it's a software problem and beloved iPod classic isn't dying as they have been discontinued.
iPod classic, OS X Yosemite (10.10.3)
