I'm in the process of moving MC to a new PC. I copied all the music files from the C drive to my external E drive, installed MC v34 on the new PC, plugged the external drive into the new PC, used the Library Tools to point MC at the new location of the music files, and so far so good.
In order to sync my library with my android player, I had created a device/drive on the old PC that pointed to a folder on the external drive and was syncing to that with a third party tool to sync to the android. However, once I unplugged the external drive that device/drive disappeared from the list in Drives & Devices, and moving the external drive back did not restore it. So, it looks like all the settings/options are now gone.
Should I expect this behavior every time I unplug the external drive? I don't plan to unplug it very often, but it seems like MC should remember the device and it's settings/options.
I've created a new "device" on the new PC, pointing to the same folder on the external drive as before, and although there's nothing to sync MC says it will take 17 hours to complete. I hope I don't have to do this every time I unplug the external drive.
