Has worked for me in many situations, back in the day drive overlays… Al From: Winterlight Sent: Monday, June 19, 2017 5:54 PM To: hardware@hardwaregroup.com Subject: [H] locked drive I have a Lenovo Edge laptop with a 500GB Samsung EVO 850 drive running windows 10 PRO. I stupidly did the Creators update last April and seance then I haven't been able to get any MS updates or even download apps from the windows store. Other programs have no problem updating. I had the same problem on another laptop. I solved that problem by restoring a backup that was pre creators update. I decided to do the same thing with the Edge. I did a restore with Acronis and it won't boot. I couldn't figure out why and, eventually I figured something must be corrupt in the boot sector so I did a wipe of the entire drive with Kill disk and, then a Acronis restore but same problem. Diagnostics report that the drive is locked which is why I can't fix it. How can I fix this? I need to get this laptop up and, running and I am prepared to buy another drive if need be. Thanks.
