I have a 2015 Macbook with an integrated 256gig SSD that has stopped working apparently due to the failing SSD. I've been able to boot into a live USB thumb drive in an attempt to try to get the failed drive to mount and hopefully recover some data using tools such as testdisk or ddrescue etc.
The MacBook seems to work fine within the Ubuntu live environment with the exception of the SSD not being properly detected or mounted. The output for dmesg shows the following:
Strangely however lspci seems to show the device being detected properly:
lshw also seems to list the device however shows storage as "UNCLAIMED"
I've tried assigning the device with "echo 106b 2001 > /sys/bus/pci/drivers/nvme/new_id" however get the following error:
Below is also the output for this device using lshw --short:
Below is the output for lspci -vvxxxs 03:00.0:
At this point I'm not sure if the device is truly not functioning properly (since it was not detected by macOS, or if there was some other kind of issue such as a corrupt partition etc. The device seems to be recongized by Ubuntu however I cannot get it to be detected properly or to mount.
I have some critical data on this device that I really need to try to access. Are there any additional steps I can take to troubleshoot this issue or try to get the device assigned and mounted? Any help would be greatly appreciated.
Thanks!
