Should be fine – i did not enter the command " defaults write com.apple.desktopservices DSDontWriteUSBStores -bool true" though
Might be benificial though - would be most effective when done before the formatting, then the .ds_store will never be made =)
I think it's most important that its added to Spotlight exclusion list directly after formatting
And i also use command-shift-dot to delete all invisible files directly after formatting
so the order would be;
1: write defaults command
2: format SD
3: add to spotlight exclusion list in system prefs
4: command-shift-dot to view invisibles and delete them
5: copy files, once at a time. i have to admit did not try all at once yet, perhaps this even works now. i do not know
6: enjoy speed =)
