I can confirm the data trashing copying to USB using CrossDOS and file comments (or too long file names or special chars in file names?)
It does trash the data by first turning an MP3 file into a directory(!!!) immidiatly followed by the above (or similar) error message but going on with the copy operation.
This is what it says in shell:
Billboard Top100 - 1977 (Dir)
100 - CJ & Co - Devil's Gun.mp3..copied.
100 - CJ & Co - Devil's Gun.mp3: directory not found
099 - John Williams - Star Wars (Main Title).mp3..copied.
099 - John Williams - Star Wars (Main Title).mp3: directory not found
098 - Leo Sayer - How Much Love.mp3..copied.
098 - Leo Sayer - How Much Love.mp3: directory not found
097 - Abba - Knowing Me, Knowing You.mp3..copied.
097 - Abba - Knowing Me, Knowing You.mp3: directory not found
096 - B J Thomas - Don't Worry Baby.mp3..copied.
096 - B J Thomas - Don't Worry Baby.mp3: directory not found
095 - Elton John - Sorry Seems To Be The Hardest Word.mp3..copied.
095 - Elton John - Sorry Seems To Be The Hardest Word.mp3: directory not found
As soon as this has happened, trying to open the dir on the stick leads to AmigaOS4 telling me the directory "lots of special ASCII chars" cannot be opened in a requester and from that point on the whole data on the stick is trashed beyond repair ... bad

At some point the copy operation will simply lock up the whole system leaving me with only the soft reset option (USB and HD lights are OFF at that point)
I can NOT, and that is probably the worst part, format the USB drive anymore. The format operation WILL start, mind you, but it will leave me with a drive that is 80 or so % FULL AFTER the format(!?)
I could only save the drive by doing a format on a Winblows machine.
I tried with Workbench copy (AsyncWB i think), shell copy (got the furthest with this one) and DirOpus copy.
I am now in the process to hunt down all files with comments, delete the comments and try again to see if it really is the case of the misbehaviour.
I use a 32GB flash drive formatted with FAT32 (30,1GB available after a fresh format) and trying to copy 20some GB of MP3's to it (using it as MusicBox on WLAN (if i ever get it to finish without locking up, that is)
edit: removed unknown message and replaced with shell output and expanded suspects with too long filenames and special chars in file names
