I am using a non-SSD drive: Western Digital Black 1TB. Windows XP (please don't judge why I'm still using XP. I've actually recentlly started to use Win 7).
For ex: if I have 2 partitions. 500GB encrypted system partition. and 500GB non encrypted partition.
Can i use Truecrypt/Veracrypt to "Wipe" the 500GB non encrypted partition by creating an encryption partition using a very secure random password? (Wiping in this context means the data in the non encrypted partition should be unrecoverable)
For example- I'll use Truecrypt/Veracrypt to "Create a New Volume" > Encrypt a Non-System Partition Drive > Choose "Create encrypted volume and format it" and then use a very secure random password and format it
And the same goes true with using "Encrypt the system Partition" and Encrypt the system partition in place? For example, if I have an unencrypted System Partition 500GB C: Drive. If I use Truecrypt/Veracrypt to "Encrypt the system Parition" and "Encrypt the system partition in place." all the data in the non encrypted system partition C: drive is now inaccessible without the password?
BTW I am using Truecrypt. (Also please don't judge why I haven't upgraded to VeraCrypt)
