This (last accessed time) does not have anything to do with mp3.
ANY file has this info (along with file creation time, file modification time) and its stored outside file (in FAT32 in case of typical thumb drive, could be NTFS, AFS, JFS EXT3 etc).
So yes MD5 of MP3 wont change, but MD5 of "directory file" should change.

TO me, this is a simple problem with the quality of the pendrive, and/or as already stated, looks like a problem with the HU. |
FAT32 is quirky, it might or might not store "last access time" (If Long filenames are enabled then it is stored).
Otherwise, it stores "Last access date".
So, if a file is accessed its FAT entry is changed to reflect last access date or last access date/time depending on how it was formatted.
I don't know if HU actually does it or not.
And I agree that this by itself will not destroy USB drive. My MP3 player mounts XD cards in RW mode, and 256 MB card is running just fine for last 2 years.
That is if HU updates "last access time" as it reads MP3/JPG/WAV files. MP3 player that I have does it, HU might or might not.
