Hello, just joined after watching Linus on youtube for the last few months. I have a question about this statement:
The big change to the encryption process itself is a new conversion mechanism that Microsoft calls Encrypt-On-Write. It ensures that all writes to disk are encrypted as soon as Bitlocker is enabled on the operating system. This works for internal drives only at the moment.
Source: https://www.ghacks.net/2017/01/06/microsoft-windows-10-bitlocker-is-slower-but-also-better/
So this "works for internal drives only". Ok, I have data that I want to encrypt on a USB flash drive. As a test, I copied a 300mb test MP4 to my BitLocker encrypted flash drive. After the copy, I had no indication that the file was encrypted. After taking the flash drive out, putting it back in and being denied access without the password it appeared that Bitlocker had done its job, no access to the drive. I suspected this would work fine but the article implies that the encryption happens (on a flash drive) at some other time. Can somebody please educate me on this? When do my flash drive files get encrypted and how will I know it's done?
Thanks!
