Per il pc il driver esiste veramente nonostante sia una emulazione e ha bisogno di trattarla come una periferica qualsiasi con i suoi driver.
Se il sistema va in crash e la disinstallazione del software non elimina anche la perfierica per qualsivoglia motivo lo devi fare a mano.

NOTE: DAEMON Tools V4 also uses SPTD (SCSI Pass Through Direct) driver to access cdroms and it is also automatically installed during DT setup. But SPTD is not removed during uninstallation because it may be used not only by DAEMON Tools but by other applications as well and its removal may disrupt these applications.
Nevertheless, if you suppose your problems are SPTD releated you can remove it as specified in this thread
