Sound mapping problem - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Hi there,
I'm new to android and don't know how things should work normally but I've found a strange behaviour:
1. I've installed Sygic Navigation on my Xperia mini pro. Some folders have automatically been created od memory card during the installation, containing Sygic sound files.
2. A couple of days later I've bought a brand new Sandisk 32GB microSD card.
3. I unmounted the old 2GB card, removed it from the phone, put into the computer's reader and copied its contents (all files, including hidden ones) to a new card.
4. I inserted the new card and mounted it.
5. From this moment on, strange things with sound files began to happen: the phone somehow changed sound mapping of previously selected ringtone, notification and alarm sounds to the Sygic's navigation sounds from the SD card.
6. When it rang or when it received an sms I could hear: "Turn left", "You've arrived" in various languages like Vietnamese, Czech, Spanish!
7. I've been able to set everything back to normal except for the notification tone which stayed the same and played even when I set it to no sound!
8. As I couldn't manage with the notification sound I've decided to format my microSD card and after I've done so, the problem disappeared, but...
9. In the phone's memory, there's a folder: /system/media/audio/notifications, containing standard system notification sounds. When I try to play these when the SD card is inserted, all I can hear are Sygic's sounds (!). When I remove SD card from the phone and try to play these files I get the "Can't play the file" message.
10. Now, who can explain it to me? How the sounds from /system/media/audio/ are dependent on the SD card?
