Bear with me as I am not anywhere near as computer savvy as most all of you. I have a laptop (Toshiba) and an external hard drive (Maxtor) I use as a backup for important files. The EHD has 20 gigs used out of 445. The other day I decided to put Truecrypt on my laptop. No problem. Yesterday I added it to the EHD. Worked fine-so far so good. Today my friend told me "if you put TC on an EHD you can only open the EHD on the computer you used to encrypt the EHD". If true that obviously renders useless the whole purpose of the EHD-as a backup for the laptop.So I would like to know 1. Is my friend correct that I cannot access the EHD on another computer than my laptop? 2. If he is wrong how exactly do I go about accessing my EHD on a third computer? 3. If he is right, how can I go about taking TC off my EHD without having to format the EHD? Thanks in advance and PLEASE keep any response as idiot proof as possible.
