Encryption help

Cheers matey i think i get it now. I didnt see the option under encypting a non system partition where you can encrypt the partition already in place :). As for container files when you create a file container and you sepcify the size you want it to be i take it thats the size of the newly "encrypted virtual drive" so anything i choose to save on this virtual drive will be encypted. What was confusing me was a lot of the tuts where showing creating a container size of 1mb. You not going to be able to do a lot mounting a 1mb container file are you?

You are correct, you will only be able to save up to 1mb in a 1mb container as the container doesn't compress files.

The only thing is...
If you create this on a FAT drive then you will not be able create a container bigger than 4GB as the FAT file system will not allow single file size's to be more than 4GB, if this is on an NTFS file system then it will be fine.

Thanks for that mate so im guessing if i dont want to encrypt my whole external HD which is NTFS i could just create say an 100GB container file and all my private info i could save in that container kinda straight forward really once you get your head around it lol. Will this mean tho if i want to access this info when i connect my hd to another machine it will have to have truecrypt installed on it? The thing is when you mount the file in truecrypt and it asks you for the password is the data "actually encrypted" or is this really just password protected data?

thanks again matey

You will need truecrypt installed on any PC you connect your HDD too otherwise it will not recognize the encrypted area.

e.g.
If you have a 350GB hard drive and have a 100GB container then when you connect it to another computer you will be able see anything in the un-encrypted 250GB area but to see the 100GB area you will need to open TrueCrypt and enter the password.

Hope this helps.

Just one more quick thing, i am trying to create a backup image using both the windows 7 image backup & Macrium Reflect, the problem is when it searches for backup devices to save the image to my encrypted partition is not showing. I setup a file container of 293gb and left 4gb spare on the HD but its only showing the 4gb external hd drive letter D and not showing the mounted encrypted disk Z which is where i want to save the image to.

Any Ideas?

Have you opened TrueCrypt and then put the password in to show the encrypted container?

If yes then create the image with a local disc and then copy the image file to the encrypted drive.

Thanks again for the responce mate, i have indeed mounted the container and enterted the password the only problem when trying to save the image to the local drive is it wont let me back up the partition i wish save it to. I have 4 partitions so if i ask it to save the image to "J which is my games partition" windows backup then wont let me back up the J partition.

thanks again
