SD card and music app problems

[Linda69]

Spoiler

I have a Sony Xperia 10v. My SD card was almost full so I decided to buy a bigger SD card to transfer to. I have been trying to use a card reader adapter but it won't copy all the files onto new SD card. I now have two problems. I can't get the SD card to copy over (been trying to use a card reader adapter and it still won't work. The second issue is some of my folders in my music have disappeared but the songs are still on the phone if I search. So how can I get the folders back (not the playlists) just the actual folders that were transferred years ago off my previous phone and how can I transfer data to new card. Hope someone can help. Thanks
