    Why would Asus encrypt the C partition


    I bought an Asus Asus X205TA, 11.6" Laptop on which Asus encrypted the C partition. This is quite annoying because you can do nothing to the C partition - no images, no recimg and even AOMEI OneKey did not work.

    For my wife we bought an Asus 10" T100 Transformer. Luckily that was not encrypted. Since the wife was so pleased with the T100, she recommended it to a friend who bought it too. And guess what, on that one the C partition was also encrypted.

    I talked to the second level support at Asus and they were also speechless. For my X205 they granted an RMA for it to be fixed at their service center in Cal. For the friends T100 we still have to negotiate.

    I wonder what interest Asus has to bitlocker encrypt the C partition. And also I thought that bitlocker would only work with 8.1 Pro - but those devices run on an 8.1 vanilla 32bit.

    How large is the laptop's hard-drive, and how much was pre-loaded?

    The hard drive is 32GB and the 32bit OS took 8GHB of space once it was installed and updated. That included Office 2013. There is also a MicroSD card slot for an additional 32GBs.

    Decrypts the drive and turns off BitLocker. All key protectors are removed when decryption is complete.

    It is possible to image BitLocker drives, at least when a TPM is not being used. It may be possible in that case, but I have no experience with it. I wrote more here on imaging with Terabyte products:

    With the prices of hard-drives, including SSDs, being very reasonable, it's best to not have encription, correct?
    And, if folder/file protection is needed, I've used 7zip to zip folders and/or separate files with a password, this is good?

    This sounds like a good idea. First problem is that this does not work.

    Image for Windows for a Windows 8.1 x64 system without a TPM, using a UEFI BIOS configured for the legacy mode.
    If you try to do that or turn Secure Boot off, you already run into the bitlocker encryption. I will try what KYHI posted - once I get a hold of the T100.

    Right, for a laptop that you use only for personal use, encryption is a nuisance. Especially if you have only benign content on it - e.g. pictures, etc.

    What has price got to do with it? It's about protecting your privacy.

    And, if folder/file protection is needed, I've used 7zip to zip folders and/or separate files with a password, this is good?
    There are too many opportunities for data leakage when using any sort of container, and I have no idea how strong the zips are. As I see it, it's best to go all-in and use FDE on everything, except things like thumb drives you use to hold drivers when installing an OS. It is possible to make it all completely seamless aside from authenticating when you boot your computer.

    As for what Asus seems to have done, I would never configure one of my own computers in such a way that I couldn't boot into a live CD or use imaging products. The good news is, you definitely can encrypt all drives including the OS drive with BitLocker without crippling yourself in those ways as I described in the message I linked to. Too bad it didn't apply to WHS's situation.
