    Hi all I'm new here I appreciate if someone can answer my questions.

    1.What is the preferred method of wiping a flash drive securely if there has been unencrypted data present on it in the past is it even possible without destroying the device with a hammer?

    2.I read in the truecrypt documentation that "its not recommended to use a flashdrive(solidstate) to store a encrypted truecrypt volume" because of wear leveling and possibly recoverable old Tc volume headers and using it to decrypt a volume if the password was changed etc.Does this effect both types of Tc containers ?



    Thx

    Sadly, the last comment in the anandtech link is 100% true. You can never be sure that a SSD is completely erased. Your only option is to physically destroy it.

    Whats safer having a truecrypt encrypted whole mechanical hardrive or flash usb stick if they are both out of the box new ?

    Is it advisable to make a new truecrypt volume every time new data is added to a hidden truecrypt volume due to it changing the sectors and making the hidden volume more detectable ?
