I have around 15 Toshiba External Hard drives and I need to password protect them and encrypt the dat.The hard drives did not come with any software to use. I have tried various Freeware software such as Veracrypt and Kleopatra, use Bitlocker as PC's are early Windows 7 pro.
I just need any advice to a simple program that can just password protect the drives, all I seem to be payable ones which I might have to result to now.
Thanks in advance
