Linux Data Recovery from failing M.2 NVMe SSD | LVM XFS dd_rescue losetup kpartx

Описание: The M.2 SSD in my laptop failed and so I'm going to attempt to recover some of the data off the failed Intel 600P NVMe SSD. I thought this would be a good video to share with you guys so that if you're ever in a situation where you need to recover data off a failed drive, this video would be helpful to you. In my case, the SSD has partitions, and one of them is managed with Linux LVM, and so I have to unravel all of that to get access to my XFS file systems.

I describe the story behind the failed drive, so if you just want to skip ahead to the actual data recovery steps, either jump to a 8:15 for an overview of the process, or jump straight to 13:29 where I begin the process of data recovery.
