I have all my contacts assigned to (usually) a unique ringtone. I have 120MB of ringtones stored on sdcard/media/ringtones. Now, I'm upgrading from an 8GB microSD card to a 32GB, to store more music. Copying the entire SD card contents off my phone, via the USB cable, directly onto the new 32GB card inserted in my PC goes smoothly, and all the apps seem to work. However, all my ringtone assignments, plus all my phone settings (for notifications, etc) get jumbles, so they all point to different mp3/wav files. Why?? And more importantly, how can I keep this from happening. I'm really not up for re-editing 500 contacts. Nor am I up for the surprises in-store when I encounter something wholly inappropriate (like my super-sweet girlfriend triggering the wicked witch of the west's theme music....).
