Hi,

a friend of mine told me that using the same password to encrypt two harddrives would be very bad. he told me about periodicity that occurs when encrypting a hard drive with a key. when you use the same password twice the periodicity could help with finding out the password.

is that true? can anyone explain more about this?

no, this is not true. the (same) passwords are mixed with random salt and then hashed so the output is different.

Alex is right. Your password only protects the master key of the volume, which is always different and generated randomly. Thanks to the random salt the header is always different even with the same password.
