How can I secure (encrypt, password protect) a portable external hard drive (500GB, NTFS) I use on a couple of different computers (not simultaneously): one computer is my work Windows 7 laptop, the other is my home Windows 10 laptop.
1) I can't find Bit Locker on my work laptop, but I do have Symantec Encryption Desktop. I don't have Symantec Encryption Desktop on my home computer though.
2) I want to secure the entire drive, not just a portion of it.
3) I use SyncToy to create backups of my external drive, to another external drive. As SyncToy works on the basis of pairing folders, I guess it is not necessary for the backup drive to be encrypted (or is it?) The backup drive is always in a secure location, so I don't really need it to be encrypted (but don't mind if it is).
4) I'm not necessarily after a "free" solution and happy to pay/subscribe for the right product.
Many thanks in advance!
