My 840 Evo kind of died last weekend. The timing is interesting and the way it's died has me curious, expecially as I can't perform a secure erase. I had windows 10 installed with bitlocker. Running windows restore from a live usb couldn't fix it. I tried various sata controllers/pcs. Some get further than others. So the best I can do it to run a linux live setup, and I can access and read 2 boot partitions and one recovery partition. The main partition is unreadable even at the dd level. So the disks isn't completely lost but I can't seem to perform a secure erase. I've tried various tools, the samsung secure erase boot disk just says that it's not possible to secure erase the disk. hdparm can't perform a secure erase. More interestingly the hdparm tool get get the drive info but the security section about whether it is locked, etc is missing. Has anyone experienced or herd of anything like this before? Is it possible for bitlocker to enable hardware encryption at a partition level rather than disk level? Is there any reason I can read from partition from a disk but performing secure erase or factory reset is not possible?

redeyes posted:Samsung has a secure erase utility worth trying. Most likely you will have to pull the power cable out of the SSD while booted with the secure erase utility, then plug back in. The drives are locked at boot up and pulling power fixes that for some reason. I've tried that, without any luck. For reference, I had another samsung ssd which I did perform a secure erase on which means I have a decent reference of what I need to do. But this ssd just appears to defy every guide and software I've come across. A normal samsung drive would say under the security section that it is locked, etc. but this drive doesn't even display that info.Oh and windows or any windows recovery tools just locks up when the drive is connected.
