XPS 9520 Edrive/SED support

If you want support for self encrypting drives, look at the Latitude or Precision line --  not the XPS models.

The laptop does support this but getting it to work properly is another story.

I set the SSD to secure mode, enabled bitlocker via a google link explaining the steps, I had to make a custom install so it prevented windows starting software encryption by default

I got it working via bitlocker as hardware encryption but the spanner in the works was the fact the BIOS now sees this as a drive with a password. Due to this on every boot it asks for the password, there is no password. You can't set a password in advance or you can't turn on drive encryption, once the password is removed you can set it on.

When it asks for the password you can click cancel, windows will boot normally.

I couldn't be doing with the password screen every time, that is not why I use bitlocker.

Back to no encryption again as this seems to be a BIOS bug.

Dell Precision line isn't much better. I believe they share the same BIOS too.

I'm due to fit new drives and RAM and wondered if anyone's had a crack at this again to see if it moans about a drive password a few BIOS revisions on.
