Lock a folder on USB External HDD

[raksrules]

I have a USB External HDD and want to store some personal data on it. Since the HDD may go through many hands for data transfer / movies etc i need some simple way to lock any folder on the drive. How can i achieve this. Let me know if there is any software (preferably freeware) available. Any other simple way would also be fine.

Some portable locking software can do that. Easier way is zip/rar the folder with password protection.

Yes, Use Windows Compression Utility

If you are so paranoid abt security use Encryption software like Truecrypt or pack the files in archive and password protect them.

Axcrypt will just work as breeze in this scenario. its a freeware.
