What is the best way to securely wipe a Gen 1 Intel X25 mlc SSD. I want the drive to remain bootable and the data to be erased fairly completely. thanks
What exactly do you mean by "remain bootable"? If you wipe the drive, there won't be any boot-related data left. However, it will still boot fine if you later reinstall an OS.
Parted Magic has a GUI program for erasing disks, which does support Secure Erase.
what I mean by bootable is I was told formatting could render the drive unable to be used as a boot drive for windows. I am just making sure before I do something wrong
The issue here is that SSDs may include more storage than is advertised on the box. This helps longevity when re-writing a few files many times on a nearly-full drive. Unfortunately, it also means that you can't be sure it's completely erased after a single pass... But how many passes is appropriate?
Do a Secure Erase. It'll erase all the blocks in the SSD, since it's implemented in the firmware of the drive itself. DBAN will unnecessarily use up quite a few write cycles and not be able to access the entire flash anyway.
