i have not read the older discussion but here is one solution
try cd lock
CD-Lock secures your removable media by scrambling the filenames and encrypting all the files with Blowfish. Yet, just enter the password when the CD is inserted into any computer running Win2000 or XP and you can instantly use the files as you always have¹ - without the need to decrypt them first.
Transparent Encryption tm
CD-Lock decrypts the files and unscrambles the names quickly and transparently, behind the scenes, so you don't have to. This allows anyone to keep their CD data secure but to effortlessly access their files instantly just by entering their password when the CD is inserted.
Works great on most removable media!
CD-Lock works great on floppy disks, CDs, DVDs, USB flash drives, etc
