I have a Samsung 850 SSD that has recently been dying on me -- there appear to be some memory issues. I'm considering sending in the drive for replacement under the warranty program, but it contains some important unencrypted information. The people at Samsung have assured me that they wipe all incoming disks, but I want to be sure.
As such, I want to wipe the drive before sending it in. The trouble is that due to the drive having memory issues, none of my software can work with the drive. My systems can pick it up as present, but not read from/write to it -- even DBAN can't overwrite it. What should I do?
Is there a way that I can figure out which parts of the drive are still readable? Are there any tools that can write data to malfunctioning drives?
