    I am currently using FreeOTFE and it is great. There was a problem with this software and contacted the developer and he fixed it the next day.

    I have also used bestcrypt traveller in the past and it was also good. I have seen explorer crashes many times when I used this and the bestcrypt traveller icon disappears from the system tray. I had to pull the pen drive out of USB and windows will give some messages once in every 5 minutes or so. I had to reboot the PC to work with it again.

    For some reason, truecrypt throws a BSOD when I tried to use in my home PC (AMD based windows XP SP3).


    • @Balaji: FreeOTFE looks really good, thanks for sharing. I personally use USB Safeguard for the simple reason that it can be installed in the USB drive itself, so that I don’t need to install encryption software on every PC that I need to use.

    Great line up thanks for sharing. :)
    I am currently using “Safe House Explorer” and have been really happy with the protection the software has provided for my USB Drive you can learn more about the software here http://www.safehousesoftware.com/SafeHouseExplorer.aspx

    • @T3CK: Safe House Explorer looks good, will try to cover it in future. Thanks for sharing :)

  • There’s a free download called ‘sample DiscreetKey’ it allows you to download software for free turning any USB stick in a DiscreetKey – this key allows you to encrypt documentation.

    The product uses the metaphor of a key – you use your DiscreetKey to ‘lock’ documentation, allowing you to store data wherever convenient for you.

    Give it a try – all you need is a blank USB!

    PLUS if you download it today and create your sample DiscreetKey you will be directed to participate in a 20 question survey and get $15!!

    Happy downloading!

    Truecrypt allows you to setup a data traveller which installs a .exe on the portable drive which will run on any Windows based PC, for USB flash disks though Windows will not allow you to partition them into multiple partitions so this can be useful for USB HDDs if you encrypt the whole partition, otherwise you can create an encrypted container with Truecrypt which can be copied to any disk and opened.

    Truecrypt is the best because its free :) . However, at work, we use http://securencrypt.com/ for file encryption and email encryption. 

  • Manisha Kofta

    I use the free trial version of Encrypt Stick. Works without admin right and includes a password manager. The trial version has a limited amount of data that you can store but that is usually more than enough. TrueCrypt is too complicated.
